Answer:
Step-by-step explanation:
Given the expression
, we are to find the value of with powers of 10.
From the equation:

cross multiply

divide both sides by 7.208

express x in powers of 10

Similarly given the equation 
From the equation:

cross multiply

divide both sides by 7.208

express x in powers of 10

For the equation 
From the equation:

cross multiply

divide both sides by 7.208

express x in powers of 10

Answer:
The largest number =5 3/4
The smallest number =1 2/5
Required difference = 5 3/4 − 1 2/5 = 4 7/2
I could be very off. hope it helps somehow
According to the information given, the ramp would be 50 feet high. (However, that seems really high. Did you type your problem correctly?)
If you draw a picture, you will see that you can set up a cosine ratio to solve this problem. With a 30 degree angle of depression, the angle we are going to use 60 degrees.
We can set up the following equation:
cos(60) = x / 100
0.5 = x / 100
50 = x
Over the x-axis: (x, y) (x, –y)
Over the y-axis: (x, y) (–x, y)
Over the line y = x: (x, y) (y, x)
Through the origin: (x, y) (–x, –y)
