Question

1. what is the scale factor of figure b to figure a?

Explanation:

Step1: Recall the formula for scale factor

Scale factor \(=\frac{\text{Corresponding side length of Figure B}}{\text{Corresponding side length of Figure A}}\)

Step2: Identify corresponding side lengths

Take the side of length \(8.6\) in Figure B and the corresponding side of length \(21.5\) in Figure A.

Step3: Calculate the scale factor

Scale factor \(=\frac{8.6}{21.5}\)

Another pair: side \(4\) in B and \(10\) in A. Scale factor \(=\frac{4}{10}=0.4\)

Answer:

\(0.4\)
