“Three decimal places” is the same as “the nearest thousandth.” So, for example, if you are asked to round 3.264 to two decimal places it means the same as if your are asked to round 3.264 to the nearest hundredth. Some questions, like the example below, will ask you to “show your answer correct to two decimal places."
The area of smaller mp3 player is 4.5 square inches
<em><u>Solution:</u></em>
Given that ratio of corresponding side lengths of two similar MP3 players is 4:3
The area of the larger MP3 player is 8 square inches
<em><u>To find: area of the smaller MP3 player</u></em>
If two MP3 players are similar, then their corresponding sides are proportional.
To find the area ratios, raise the side length ratio to the second power
From given information,
area of larger mp3 = 8 square inches
Let the area of smaller mp3 = x
So the above ratio becomes,
Thus the area of smaller mp3 player is 4.5 square inches
Answer:
isolate variable by adding or subtracting it on both sides.
