The scale factor would be 0.2 because you have to divide the new stamp by the original so it would be 1.9/9.5=0.2 and same with 1.4/7=0.2

Answer:

5/8

Step-by-step explanation:

A.   2/3 × 4/5 × m = 1/3               B.      4/5 × 2/3 × m = 1/3

      8/15 × m = 1/3                                 8/ 15 × m  = 1/3                                    

                 m = 1/3 ÷ 8/15                                 m = 1/3 ÷ 8/15

                  m = 1/3 ×15/8                                 m = 1/3  × 15/8

                  m = 5/8                                          m = 5/8        

C.  2/3 × 4/5 = 1/3 ÷ m        

            8/15 =  1/3 ×  1/m

            8/15 = 1/3m                   cross multiply  

           (3m) × (8) = 15

                24m = 15

                     m = 15/24

                     m=  5/8

The scale factor that Thea uses to go from Rectangle Q to Rectangle R is equal to 6.

<h3>What is the scale factor from rectangle Q to rectangle R?</h3>

In geometry, the scale factor is a ratio of the resulting length to the initial length. Since the area of the square is equal to the square of its side length, then the scale factor is equal to:

k² = A' / A

k = √(A' / A)

Where:

  • k - Scale factor
  • A' - Area of the rectangle R.
  • A - Area of the rectangle Q.

If we know that A = 2 and A' = 72, then the scale factor is:

k = √(72 / 2)

k = √36

k = 6

Then, the scale factor that Thea uses to go from Rectangle Q to Rectangle R is equal to 6.
