Question

A model of a volcano has a scale of 2.5 inches to 1.000 feet. If the model is 18 inches high, find

the height of the volcano. (1ft = 12in)


Pls help me solve this!!!

Answer 1

To solve this problem, we can set up the following equation:

2.5 inches = 1,000 feet

We are told that the model is 18 inches high, so we can write the following equation:

18 inches = X feet

To solve for X, we can cross-multiply the equations to get:

(2.5 inches)X = (1,000 feet)(18 inches)

Simplifying this equation, we get:

X = 4,500 feet

Therefore, the height of the volcano is 4,500 feet.

Answer 2

Answer = 7, 200 ft

Explanation

1. Set up a proportion with the given information to solve for the height of the volcano. It would be 2.5/1000 ft = 18/x.

2. Cross multiply. 2.5x = 18000.

3. Divide 2.5 on both sides to get the variable by itself leaving x = 7, 200 ft
