PLEASE HELPP !!!!!!!

Answer 1

The actual length of the helicopter is 23 feet.

Explanation:

Given:

On a scale drawing, a helicopter is 2.3 feet long.

The scale on the drawing shows a ratio of 1 foot to 10 feet.

Now, to find the actual length of the helicopter.

Let the actual length of helicopter be
`x`.

On scale drawing length of helicopter = 2.3 feet.

The scale on the drawing shows a ratio = 1:10.

Now, as ratios are given so by setting proportion we solve it:

`(2.3)/(x) =(1)/(10)`

By cross multiplying we get:

⇒
`2.3* 10=x`

⇒
`23=x`

⇒
`x=23\ feet.`

Therefore, the actual length of the helicopter is 23 feet.
