- thanks in advance!!

Answer 1

Answer:

25 feet

Step-by-step explanation: 5/3 is 1.6 repeated so you can do 3 times 5 to get the shadow and since we did that to the bottom then we have to do that to the top and it would be 25/15 which is 1.6 repeated as well.

Answer 2

The height of the tree is 25 feet.

Given that,

Andy is 5 ft tall and casts a 3-foot shadow.

At the same time, a tree casts a 15-foot shadow.

We have to determine,

What is the height of the tree?

According to the question,

A proportion comparing the height of each object to the length of the shadow.

Andy is 5 ft tall and casts a 3-foot shadow.

At the same time, a tree casts a 15-foot shadow.

Then,

The height of the tree is,

$= \dfrac{h}{s}\\\\= \dfrac{h}{15} = \dfrac{5}{3}\\\\= 3\times h = 5 \times 15\\\\= 3h = 75\\\\h = \dfrac{75}{3}\\\\h = 25 \ feet$

Hence, The height of the tree is 25 feet.
