One day, a corn stalk was 0.85 m tall. A tomato plant was 0.850 m. A carrot top was 0.085 m. 0 tenths are less than the 8 tenths. So, 0.085 is less than 0.85 or 0.850.

Explain.<br \/>\nType below:<br \/>\n_________<\/p>\n<p>Answer:<br \/>\nThe slowest speed to the thousandths that could round to 5.67 meters per second is 5.671<br \/>\nThe fastest speed to the thousandths that could round to 5.67 meters per second is 5.674<\/p>\n<p>Explanation:<br \/>\nTo find the slowest speed to the thousandths that could round to 5.67 meters per second we need to find the lowest digit which will not affect the digit in the hundredths place, and that is 1. So, the slowest speed to the thousandths that could round to 5.67 meters per second is 5.671.<br \/>\nTo find the fastest speed to the thousandths that could round to 5.67 meters per second we need to find the greatest digit which will not affect the digit in the hundredths place, and that is 4.

During August, the plant grew 18.2 centimeters.<br \/>\nPart A<br \/>\nEstimate the height of Yolanda\u2019s plant at the end of August by rounding each value to the nearest whole number. Will your estimate be less than or greater than the actual height? Explain your reasoning.<br \/>\n_____ cm<\/p>\n<p>Answer:<br \/>\nFirst, we want to round the number 64.34 to the nearest whole number.<br \/>\n1. We have to round this number to the molest tenth. To round the number to the nearest tenth we need to look at the digit in the hundredths place. So, as 4 &lt; 5, the rounded number is 64.3.<br \/>\n2. We now have to round this number to the nearest one. lb round the number to the nearest one we need to look at the digit in the tenths place. So, as 3 &lt; 5, the rounded number is 64.<br \/>\nNow, we have to round the number 18.2 to the nearest whole number.<br \/>\n1. We have to round this number to the nearest one. To round the number to the nearest one we need to look at the digit in the tenths place. So, as 2 &lt;5, the rounded number is 18.<br \/>\nSo, we now have to find the sum of these rounded values: 64 + 18 = 82. Therefore, the estimated height of Volanda&#8217;s plant at the and of August is: 82 centimeters.<br \/>\nThe estimate is less than the actual height because rounded values are less than the actual values.<\/p>\n<p>Question 17.<br \/>\nPart B<br \/>\nWhat was the exact height of the plant at the end of August? Was the estimate less than or greater than the exact value?<br \/>\n_____ cm<\/p>\n<p>Answer:<br \/>\nThe exact height of the plant is: 64.34 + 18.2<br \/>\nAdd the hundredths first.<br \/>\n4 hundre.dths + 0 hundredths = 4 hundredths<br \/>\nAdd the tenths.<br \/>\n3 tenths + 2 tenths = 5 tenths Add the ones. Regroup as nee.ded<br \/>\nAdd the tens.<br \/>\n6 tens + 1 ten + 1 regrouped ten = 8 tens.<br \/>\nTherefore, the exact height is 64.34+ 18.2 = 82.54.<br \/>\nThe estimate is less than the actual height.<\/p>\n<h3><a id=\"Review\/Test_\u2013_Page_No._164\"><\/a>Chapter Review\/Test &#8211; Page No. 164<\/h3>\n<p>Question 18.<br \/>\nOscar ran the 100-yard dash in 12.41 seconds.
