Question

A tree has a shadow that is 9 feet long. Otis is 4 feet tall, and he is standing next to the tree. Otis has a shadow that is 4.5 feet long.

Answer 1

Answer:

8 ft

Step-by-step explanation:

We can use ratios to solve

tree                          Otis

--------------------  = --------------

tree shadow          Otis shadow

tree                   4 ft

-------------- = ----------------

9 ft                   4.5 ft

Using cross products

4.5 tree = 4* 9

4.5 tree = 36

Divide each side by 4.5

tree = 36/4.5

tree =8
