Question

Use proportions to solve these activities. Round your 17 A caboose is approximately 30 f long. How long is a 25 scale model? Solve for the missing side. Write the length on th Х 19)

Answer 1

We will assume that the scale model of the caboose is 17, and its approximately 30 feet long, and we will find the length for a 25 scale model.

For doing so, we will take the following proportion:

`(17)/(30)=(25)/(x)`

And we will use the fundamental property of proportions, for multiplying mediums and extremes:

`\begin{gathered} 17x=25\cdot30 \\ 17x=750 \\ x=(750)/(17)=44.116 \end{gathered}`

This means that under our assumptions, the 25 scale model caboose will have a size of 44.116 feet long.
