f is given as -3
-3 is greater than -4, so use the second equation 3x-5.
replace x with -3 and calculate:
3(-3) - 5 = -9 - 5 = -14
The answer is -14.
We can set up a proportion to solve this problem as follows:
height of the model/width of the model= height of the actual/width of the actual
24/18=60/x
Cross multiply,
24x=18*60
24x=1080
x=45 ft.
Therefore the answer is 45 ft.

Answer:
The length of the ramp must be at least 14.71 feet
Step-by-step explanation:
Given


<em>See attachment for complete figure</em>
Required
Length of the ramp (z)
To do this, we consider sin of angle A (
).
So, we have:

This gives:

Make z the subject



<em>The length of the ramp must be at least 14.71 feet</em>
