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

The scale factor dilating from the red image to the blue image is 1/4

Step-by-step explanation:

we know that

A dilation is a non rigid transformation that produce similar figures

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

In this problem

Figure ABCD and Figure A'B'C'D' are similar

so

using proportion

substitute the given values

The scale factor dilating from the red image to the blue image is 1/4

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
