Question

Find the missing dimension.

Use the scale 1: 15.
Item: Pipe
Model: Length: 5 ft
Actual: Length:___ft

Answer 1

75ft

Explanation:

Hello There! With the information given in the problem we can set up a ratio in order to help us solve for the actual length that the model is scaled upon.

This ratio can be written as:

`(1ft)/(15ft)`

From this we just set up another ratio in relation to the original. In this one we will be solving for x.

`(1ft)/(15ft)` x
`(5ft)/(x)`

After solving for x we find that the actual model should be roughly 75ft.

Hope this helps!
