Question

The scale from a stadium video screen to this drawing is 9 ft to 1 in. The scale from the same video screen to a second drawing is 6 ft to 1 in. What is the height of the second drawing of the video screen? Use the number pad to enter your answer in the box h = 3.5 in. in w = 8.5 in.

Answer 1

First, we have to calculate the height of te video screen:

`\begin{gathered} 1in\to9ft \\ 3.5in\to x \\ x=3.5in\cdot(9ft)/(1in)=31.5ft \end{gathered}`

So, the height of the video screen is 31.5ft.

Now, we can calculate the height of the second drawing:

`\begin{gathered} 6ft\to1in \\ 31.5ft\to x \\ x=31.5ft\cdot(1in)/(6ft)=5.25in \end{gathered}`

The height of the second drawing is 5.25 in
