f a basketball player is 90 inches tall and the scale factor for his model bobble head is 1:20. How tall is the model bobble head in inches?

4.5 inches

Step-by-step explanation:

The scale factor is 1:20 which is 1/20, and the actual height is 90 inches.

First, write down the proportion:

1/20 = x/90

Multiply both sides by 90.

=> x = 90/20

=> x = 4.5in

Therefore, the height of the model is 4.5 inches.
