Significant figures help to find and establish the number that is in the form of digits. The significant digits used instead of figures. It is easy to identify significant digits by counting the numbers from the 1st non-zero digit located on the left. Significant figures of any given number are nothing but the significant digits they used to convey the meaning according to its accuracy. For example, 2.238 has four significant digits.

Clearly understand the topics available below.

• Rules to find the number of significant figures
• Rounding off a decimal to the required number of significant figures
• Round off to a special unit.

Significant Figures Rules

1. All non–zero numbers (1, 2, 3, 4, 5) are always significant.

Example:

• 2154 has four significant figures
• 142.35 has four significant figures

2. All zeros between non-zero numbers are always significant.

Example:

• 305.003 has six significant figures.
• 70.00 has four significant figures.
• 61.04020 has seven significant figures.

3. In a decimal number that lies between 0 and 1, all zeros that are to the right of the decimal point but to the left of a non-zero number are not significant.

Example:

• 0.00365 has only three significant figures.
• 0.006040 has four significant figures.

4. In a whole number if there are zeros to the left of an understood decimal point but to the right of a non-zero digit, the case becomes doubtful.

Example:

• 304000 there is an understood decimal point after the given six digits. There are 3 zeros that present to the left of the understood decimal point but to the right of a non-zero number so the case becomes doubtful.
• It is represented as 3.04 × 10⁵ also it consists of 3 significant figures. Also, it can represent as 3.040 × 10⁵, then the number of significant figures is 4.

5. When a decimal is round off to a given number of decimal places, all the final zeros in a decimal number are significant.

Example:

• If we round off 2.875 to two decimal places, we get 3.90 which has 3 significant figures.

Learn how a pair of angles formed between Parallel and Transversal Lines. When two parallel lines intersect by a Transversal Line, they form different angles. Those angles are given with different names based on their location. Therefore, check what are the angles formed and how to find them, and what names are given to them depending on their location. You can also get all concepts and examples available on Lines and Angles for free on our website.

When the transversal intersects two parallel lines

• Pairs of alternate angles are equal
• Pairs of corresponding angles are equal.
• Interior angles on the same side of the transversal are supplementary.

Parallel Lines Cut by a Transversal Problems

1. In adjoining figure l ∥ m is cut by the transversal t. If ∠5 = 70, find the measure of ∠7, ∠9, ∠10.

Solution:
Given that ∠5 = 70° ∠5 = ∠7 (Vertically opposite angles)
Therefore, ∠7 = 70°
Now, ∠5 = ∠9 (Corresponding angles)
Therefore, ∠9 = 70°
Also, ∠7 + ∠10 = 180° (Co-interior angles)
70° + ∠10 = 180°

Therefore, ∠10 = 180° – 70° = 110°

2. In the given figure PQ ∥ RS, ∠QAO = 125°, ∠RBO = 40°. Find the measure of ∠AOB.

Solution:

Draw a line AB parallel to PQ and RS passing through O such that PQ ∥ MN and RS ∥ MN
∠QAO + ∠NOA = 180° (Co-interior angles)
Therefore, 125° + ∠NOA = 180°
Therefore, ∠NOA = 180° – 125° = 55°
Also, ∠RBO = ∠NOB (Alternate angles)
Given ∠RBO = 40°
Therefore, ∠NOB = 40°
Then ∠AOB = ∠AON + ∠BON
= 55° + 40° = 95°

3. In the given figure NM ∥ PO ∥ SR and NS ⊥ NM. Also, ∠MNS = 90°. Find the values of ∠a, ∠b and ∠c.

Solution:

b + 45° = 180°
Therefore, ∠b = 180° – 45° (Co-interior angles) = 135°
∠b =∠a (Corresponding angles)
Therefore, ∠a = 135°
Also, 90° + ∠c + 45° = 180°
Therefore, 135° + ∠c = 180°
Therefore, ∠c = 180° – 135° = 45°

The final answer is ∠a = 135°, ∠b = 135°, ∠c = 45°

4. In the given figure, MN ∥ QP, QP ∥ RS, QR ∥ OP. Also, ∠6 = 60°, ∠8 = 55°, then find ∠7, ∠9, ∠10.

Solution:

Since, QR ∥ OP cut by transversal QP
Therefore, ∠8 = ∠10 we know, ∠8 = 55°
Therefore, ∠10 = 55°
Also, QP ∥ XY cut by transversal OP
Therefore, ∠10 = ∠x we know ∠10 = 55°
Therefore,∠x = 55°
Also, ∠x + ∠1 + ∠y = 180°
55° + 60° + ∠y = 180°
115° + ∠y = 180°
∠y = 180° – 115°
Therefore, ∠y = 65°
Now, ∠y + ∠2 = 1800 (Co-interior angles)

65° + ∠7 = 180°
∠7 = 180° – 65°
∠7 = 115°
Since, QP ∥ RS cut by transversal QR
Therefore, ∠8 + ∠9 = 180°
55° + ∠9 = 180°
Therefore, ∠9 = 180° – 55° = 125°

The final answer is ∠7 = 115°, ∠9 = 125°, ∠10 = 55°.

5. In the given figure AB ∥ EF. Also, m : n = 4 : 5 find.

Solution:
Let the common ratio be x
Then m = 4x and n = 5x
Also, ∠n = ∠o (Alternate interior angles)
Since, n = 5x
Therefore, ∠o = 5x [CD ∥ EF cut by transversal t]
Now, ∠o = ∠l (Corresponding angles)
Since, ∠o = 5x
Therefore, ∠l = 5x [AB ∥ CD cut by transversal t]
∠l + ∠m = 180° (Co-interior angles)
5x + 4x = 1800
9x = 180°
x = 180/9
x = 20
Since, m = 4x
Therefore, m = 4 × 20
m = 80°
n = 5x
Therefore, n = 5 × 20
n = 100°
l = 5x
Therefore, l = 5 × 20
l = 100°

Therefore, ∠l = 100°, ∠m = 80°, ∠n = 100°

Example 1. The Distance Between Points on an Axis
Consider the points (- 4, 0) and (5, 0).
What do the ordered pairs have in common, and what does that mean about their location in the coordinate plane?
Answer:
Both of their y-coordinates are zero, so each point lies on the x-axis, the horizontal number line.

How did we find the distance between two numbers on the number line?
Answer:
We calculated the absolute values of the numbers, which told us how far the numbers were from zero. If the numbers were located on opposite sides of zero, then we added their absolute values together. If the numbers were located on the same side of zero, then we subtracted their absolute values.

Use the same method to find the distance between (- 4, 0) and (5, 0).
Answer:
|- 4| = 4 and |5| = 5. The numbers are on opposite sides of zero, so the absolute values get combined: 4 + 5 = 9. The distance between (- 4, 0) and (5, 0) is 9 units.

Example 2.
The Length of a Line Segment on an Axis
Consider the line segment with end points (0,- 6) and (0, – 11).
What do the ordered pairs of the end points have in common, and what does that mean about the line segment’s location in the coordinate plane?
Answer:
The x-coordinates of both end points are zero, so the points lie on the y-axis, the vertical number line. If its end points lie on a vertical number line, then the line segment itself must also lie on the vertical line.

Find the length of the line segment described by finding the distance between its end points (0,- 6) and (0, – 11).
Answer:
|- 6| = 6 and |- 11| = 11. The numbers are on the same side of zero, which means the longer distance contains the shorter distance, so the absolute values need to be subtracted: 11 – 6 = 5. The distance between (0, – 6) and (0, – 11) is 5 units, so the length of the line segment with end points (0, – 6) and (0, – 11) is 5 units.

Example 3.
Length of a Horizontal or Vertical Line Segment That Does Not Lie on an Axis
Consider the line segment with end points (- 3, 3) and (- 3, – 5).
What do the end points, which are represented by the ordered pairs, have in common? What does that tell us about the location of the line segment on the coordinate plane?
Answer:
Both end points have x-coordinates of – 3, so the points lie on the vertical line that intersects the x-axis at – 3. This means that the end points of the line segment, and thus the line segment, lie on a vertical line.

Find the length of the line segment by finding the distance between its end points.
Answer:
The end points are on the same vertical line, so we only need to find the distance between 3 and – 5 on the number line.
|3| = 3 and |- 5| = 5, and the numbers are on opposite sides of zero, so the values must be added: 3 + 5 = 8. So, the distance between (- 3, 3) and (- 3, – 5) is 8 units.

Exercise

Find the lengths of the line segments whose end points are given below. Explain how you determined that the line segments are horizontal or vertical.
a. (- 3, 4) and (- 3, 9)
Answer:
Both end points have x-coordinates of – 3, so the points lie on a vertical line that passes through – 3 on the x-axis. |4| = 4 and |9| = 9, and the numbers are on the same side of zero. By subtraction, 9 – 4 = 5, so the length of the line segment with end points (- 3, 4) and (- 3, 9) is 5 units.

b. (2, – 2) and (- 8, – 2)
Answer:
Both end points have y-coordinates of – 2, so the points lie on a horizontal line that passes through – 2 on the y-axis. |2| = 2 and |- 8| = 8, and the numbers are on opposite sides of zero, so the absolute values must be added. By addition, 8 + 2 = 10, so the length of the line segment with end points (2, – 2) and (- 8, – 2)is 10 units.

c. (- 6, – 6) and (- 6, 1)
Answer:
Both end points hove x-coordinates of – 6, so the points lie on a vertical line. |- 6| = 6 and |1| = 1, and the numbers are on opposite sides of zero, so the absolute values must be added. By addition, 6 + 1 = 7, so the length of the line segment with end points (- 6, – 6) and (- 6, 1) is 7 units.

d. (- 9, 4) and (- 4, 4)
Answer:
Both end points have y-coordinates of 4, so the points lie on a horizontal line. |- 9| = 9 and |- 4| = 4, and the numbers are on the same side of zero. By subtraction, 9 – 4 = 5, so the length of the line segment with end points (- 9, 4) and (- 4, 4) is 5 units.

e. (0, – 11) and (0, 8)
Answer:
Both end points hove x-coordinates of 0, so the points lie on the y-axis. |- 11| = 11 and |8| = 8, and the numbers are on opposite sides of zero, so their absolute values must be added. By addition, 11 + 8 = 19, so the length of the line segment with end points (0, – 11) and (0, 8) is 19 units.

Question 1.
Find the length of the line segment with end points (7, 2) and (- 4, 2), and explain how you arrived at your solution.
Answer:
11 units. Both points have the same y-coordinate, so I knew they were on the same horizontal line. I found the
distance between the x-coordinates by counting the number of units on a horizontal number line from – 4 to zero and then from zero to 7, and 4 + 7 = 11.
or
I found the distance between the x-coordinates by finding the absolute value of each coordinate. |7| = 7 and |- 4| = 4. The coordinates lie on opposite sides of zero, so I found the length by adding the absolute values together. Therefore, the length of a line segment with end points (7, 2) and (- 4, 2) is 11 units.

Question 2.
Sarah and Jamal were learning partners in math class and were working independently. They each started at the point (- 2, 5) and moved 3 units vertically in the plane. Each student arrived at a different end point. How is this possible? Explain and list the two different end points.
Answer:
It is possible because Sarah could have counted up and Jamal could have counted down or vice versa. Moving 3 units in either direction vertically would generate the following possible end points: (- 2, 8) or (- 2, 2).

Question 3.
The length of a line segment is 13 units. One end point of the line segment is (- 3,7). Find four points that could be the other end points of the line segment.
Answer:
(- 3, 20), (- 3, – 6), (- 16, 7) or (10, 7)

Question 1.
Determine whether each given pair of end points lies on the same horizontal or vertical line. If so, find the length of the line segment that joins the pair of points. If not, explain how you know the points are not on the same horizontal or vertical line.

a. (0, – 2) and (0, 9)
Answer:
The end points both have x-coordinates of 0, so they both lie on the y-axis, which is a vertical line. They lie on opposite sides of zero, so their absolute values have to be combined to get the total distance. |- 2| = 2 and |9| = 9, so by addition, 2 + 9 = 11. The length of the line segment with end points (0, – 2) and (0, 9) is 11 units.

b. (11, 4) and (2, 11)
Answer:
The points do not lie on the same horizontal or vertical line because they do not share a common x- or y-coordinate.

c. (3, – 8) and (3, – 1)
Answer:
The end points both have x-coordinates of 3, so the points lie on a vertical line that passes through 3 on the x-axis. The y-coordinates lie on the some side of zero. The distance between the points is determined by subtracting their absolute values, |- 8| = 8 and |- 1| = 1. So, by subtraction, 8 – 1 = 7. The length of the line segment with end points (3, – 8) and (3, – 1) is 7 units.

d. (- 4, – 4) and (5, – 4)
Answer:
The end points have the same y-coordinate of – 4, so they lie on a horizontal line that passes through – 4 on the y-axis. The numbers lie on opposite sides of zero on the number line, so their absolute values must be added to obtain the total distance, |- 4| = 4 and |5| = 5. So, by addition, 4 + 5 = 9. The length of the line segment with endpoints (- 4, – 4) and (5, – 4) is 9 units.

Eureka Math Grade 6 Module 3 Lesson 18 Opening Exercise Answer Key

Four friends are touring on motorcycles. They come to an intersection of two roads; the road they are on continues straight, and the other is perpendicular to it. The sign at the intersection shows the distances to several towns. Draw a map/diagram of the roads, and use it and the information on the sign to answer the following questions:

What is the distance between Albertsville and Dewey Falls?
Answer:
Students draw and use their maps to answer. Albertsville is 8 miles to the left, and Dewey Falls is 6 miles to the right. Since the towns are in opposite directions from the intersection, their distances must be combined by addition, 8 + 6 = 14, so the distance between Albertsville and Dewey Falls is 14 miles.

What is the distance between Blossville and Cheyenne?
Answer:
Blossville and Cheyenne are both straight ahead from the intersection in the direction that they are going. Since they are on the same side of the intersection, Blossville is on the way to Cheyenne, so the distance to Cheyenne includes the 3 miles to Blossville. To find the distance from Blossville to Cheyenne, I have to subtract; 12 – 3 = 9. So, the distance from Blossville to Cheyenne is 9 miles.

On the coordinate plane, what represents the intersection of the two roads?
Answer:
The intersection is represented by the origin.

Students practice estimating size of quantities and performing operations on numbers written in the form of a single-digit integer times a power of 10.

Question 1.
The Atlantic Ocean region contains approximately 2×10¹² gallons of water. Lake Ontario has approximately 8,000,000,000,000 gallons of water. How many Lake Ontarios would it take to fill the Atlantic Ocean region in terms of gallons of water?
Answer:
8 000 000 000 000=8×10¹²
\(\frac{2 \times 10^{16}}{8 \times 10^{12}}\)=\(\frac{2}{8}\)×\(\frac{10^{16}}{10^{12}}\)
=\(\frac{1}{4}\)×10⁴
=0.25×10⁴
=2500
2,500 Lake Ontario’s would be needed to fill the Atlantic Ocean region.

Question 2.
U.S. national forests cover approximately 300,000 square miles. Conservationists want the total square footage of forests to be 300,000² square miles. When Ivanna used her phone to do the calculation, her screen showed the following:

a. What does the answer on her screen mean? Explain how you know.
Answer:
The answer means 9×10¹⁰. This is because:
(300 000)²=(3×10⁵)²
=3²×(10⁵)²
=9×10¹⁰

b. Given that the U.S. has approximately 4 million square miles of land, is this a reasonable goal for conservationists? Explain.
Answer:
4 000 000=4×10⁶. It is unreasonable for conservationists to think the current square mileage of forests could increase that much because that number is greater than the number that represents the total number of square miles in the U.S,
9×10¹⁰>4×10⁶.

Question 3.
The average American is responsible for about 20,000 kilograms of carbon emission pollution each year. Express this number as a single-digit integer times a power of 10.
Answer:
20 000=2×10⁴

Question 4.
The United Kingdom is responsible for about 1×10⁴ kilograms of carbon emission pollution each year. Which country is responsible for greater carbon emission pollution each year? By how much?
2×10⁴>1×10⁴
Answer:
America is responsible for greater carbon emission pollution each year. America produces twice the amount of the U.K. pollution.

Most English-speaking countries use the short-scale naming system, in which a trillion is expressed as 1,000,000,000,000. Some other countries use the long-scale naming system, in which a trillion is expressed as 1,000,000,000,000,000,000,000. Express each number as a single-digit integer times a power of ten. How many times greater is the long-scale naming system than the short-scale?
Answer:
1 000 000 000 000=10¹²
1 000 000 000 000 000 000 000=10²¹
\(\frac{10^{21}}{10^{12}}\). The long-scale is about 10⁹ times greater than the short-scale.

Example 1.
Mother’s 10K Race
Sam’s mother has entered a 10K race. Sam and his family want to show their support for their mother, but they need to figure out where they should go along the race course. They also need to determine how long it will take her to run the race so that they will know when to meet her at the finish line. Previously, his mother ran a 5K race with a time of 1\(\frac{1}{2}\) hours. Assume Sam’s mother will run the same rate as the previous race in order to complete the chart.

→ Discuss with your partner: Can you find Sam’s mother’s average rate for the entire race based on her previous race time?
→ 3\(\frac{1}{3}\) km/h, or \(\frac{10}{3}\) km/h

Create a table that shows how far Sam’s mother has run after each half hour from the start of the race, and graph it on the coordinate plane to the right.

Answer:

a. What are some specific things you notice about this graph?
Answer:
It forms a line through the origin; it relates time (in hours) to the distance run (in kilometers); the line through the origin means that the values are proportional.

b. What is the connection between the table and the graph?
Answer:
The time (in hours) is on the horizontal axis, and the distance run (in kilometers) is on the vertical axis; the coordinates of the points on the line are the same as the pairs of numbers in the table.

c. What does the point (2, 6\(\frac{2}{3}\) ) represent in the context of this problem?
Answer:
After 2 hours, she has run 6 \(\frac{2}{3}\) km.

Discuss the responses with the class and draw a conclusion.
→ Write an equation that models the data in the chart. Record the student responses so that they can see all of the responses.
→ D = 3\(\frac{1}{3}\) H, where D represents the distance, and H represents the hours (or D=\(\frac{10}{3}\) H).

c. Write an equation to model this data.
Answer:
C = 8w

d. What ordered pair represents the unit rate, and what does it mean?
Answer:
(1, 8) The unit rate is 8, which means that one pound of mushrooms costs $8.00.

e. What does the ordered pair (2, 16) mean in the context of this problem?
Answer:
(2, 16) This means 2 pounds of mushrooms cost $16.00.

f. If you could spend $10.00 on mushrooms, how many pounds could you buy?
Answer:
C = 8w; C = 10;(\(\frac{1}{8}\) )10 = (\(\frac{1}{8}\) )8w; 1 \(\frac{1}{4}\) = w. You can buy 1.25 pounds of mushrooms with $10.00.

At the end of the second day, there were 1,769 milliliters of paint remaining in the barrel. Total amount of the paint is
6 L 775 mL + 1 L 118 mL = 7 L 893 mL,
Paint left after first day is 7 L 893 mL – 2 L 125 mL =
7 L 893 mL = 7 X 1000 mL + 893 mL = 7,893 mL,
2 L 125 mL = 2 X 1000 mL + 125 mL = 2,125 mL,
So 7,893 mL – 2,125 mL = 5,768 mL paint is left after first day,

Given On Thursday, the pizzeria used less 2 kilograms 180 grams
less flour than they used on Friday. On Friday, they used
12 kilograms 240 grams. On Saturday, they used 1,888 grams
more than on Friday. So on Thursday they used
12 kg 240 g – 2 kg 180 g =
12 X 1000 g + 240 g = 12,240 g,
2 X 1000 + 180 g = 2,180g,
12,240 g – 2,180 g = 10,060 g on Thursday,
On Saturday they used 1,888 g + 12,240 g = 14,128 g,
Now the total amount of flour used over the three days is
10,060 g + 12,240 g + 14,128 g = 36,428 g or 36,428 g ÷ 1000 =

Explanation:
Given the gas tank in Zachary’s car has a capacity of 60 liters.
He adds 23 liters 825 milliliters of gas to the tank,
which already has 2,050 milliliters of gas.
So  the gas tank has  23 L 825 mL + 2,050 mL =
as 23 L 825 mL = 23 X 1000 mL + 825 mL =
23,000 mL + 825 mL = 23,825 mL gas,
Now 23,825 mL + 2,050 mL = 25,875 mL
More gas can Zachary add to the gas tank is 60 L – 25,875 mL =
as 60 L = 60 X 1,000 mL = 60,000 mL,
So 60,000 – 25,875 mL = 34,125 mL or 34,125 mL ÷ 1000 =

Explanation:
Given A giraffe is 5 meters 20 centimeters tall. An elephant is
1 meter 77 centimeters shorter than the giraffe and
A rhinoceros is 1 meter 58 centimeters shorter than
the elephant. So height of rhinoceros is first we see
height of elephant as 5 m 20 cm – 1 m 77 cm =
as 5 X 100 cm + 20 cm = 5,20 cm and
1 m 77 cm = 1 X 100 cm +77 cm = 1,77 cm,
so 520 cm – 177 cm = 343 cm, Now rhinoceros is
343 cm – 1 m 58 cm =
as 1 m 58 cm = 1 X 100 cm + 58 cm = 158 cm
so 343 cm – 158 cm = 185 cm or 185 cm ÷ 100 = 1 m 85 cm,
therefore the rhinoceros is 185 centimeters tall or
1 meter 85 centimeters tall, modeled problem with a
