Answer:
The actual length of the helicopter is 23 feet.
Step-by-step 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 [tex]x[/tex].
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:
[tex]\frac{2.3}{x} =\frac{1}{10}[/tex]
By cross multiplying we get:
⇒ [tex]2.3\times 10=x[/tex]
⇒ [tex]23=x[/tex]
⇒ [tex]x=23\ feet.[/tex]
Therefore, the actual length of the helicopter is 23 feet.
