Rachel purchased different carpets that had the same ratio of the length to the width. the table below shows the length and width of some carpets rachel bought: length (feet) width (feet) 4 3 8 6 12 9 16 12 ? 15 the missing value in the table is feet. numerical answers expected! answer for blank 1:

4 3

8 6

12 9

16 12

? 15

Let's take a look at the numbers running down the left. They are increasing by how much?

Take a look at the numbers running down the right. They are increasing by how much?

Our carpets continue to have the ratio of 4:3.

Because these two columns (L & W) are increasing by the same rate for each carpet piece, we say they have the same ratio of L to W.

The missing piece has to be 20 by 15 (a ratio of 4:3)

-4

step-by-step explanation:

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
