What is the approximate scale factor dilating from the blue image to the red image? explain how you figured this out.

The approximate scale factor dilating from the blue image to the red image is 3.5

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is equal and this ratio is called the scale factor

see the attached figure to better understand the problem

Let

z------> the scale factor

Observing the attached figure

AB=x

A'B'=3.5x

substitute

ruth is 6 years old

step-by-step explanation:

6 + 24 = 30,   so 6/30 = .2  

if you do 1/5 it also equals .2, so that is the answer.

.632

step-by-step explanation:

6 * 1/10 = 3/5

3*0.01 = 0.03

3/5 + 0.03 = .63

2*0.002 = .002

.63 + 0.002 = .632
