Question

Izzy measures and finds that she can do a vertical jump that is 27.5% of her height. If Izzy can jump 13.2 inches, how tall is she?

a) 36 inches
b) 42 inches
c) 48 inches
d) 54 inches

Answer 1

Izzy's height is 48 inches.

Step-by-step explanation:

To find Izzy's height, we can set up a proportion using her vertical jump and the given percentage. Let's say Izzy's height is h inches. We can set up the proportion as: (13.2 / h) = (27.5 / 100). We cross multiply and solve for h: 13.2 * 100 = 27.5 * h. Simplifying gives: 1320 = 27.5h. Divide both sides by 27.5 to find h: h = 48 inches. Therefore, Izzy's height is 48 inches, so the correct answer is c) 48 inches.
