Answer:
The answer is 8 feet.
Step-by-step explanation:
Let x = height where the ladder hits the building
7 squared+x squared=25 squared
49+x squared=625
x squared=576
x=24 feet
Let x = distance from wall:
x^2 + 20^2 = 25^2
x^2 + 400 = 625
x^2 = 225
x = 15 feet

Answer:
0.9 = 90%
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability that we find a value X between c and d is given by the following formula.

Miles per gallon of a vehicle is a random variable with a uniform distribution from 25 to 35.
This means that 
The probability that a random vehicle gets between 25 and 34 miles per gallon is:

So the answer is 0.9 = 90%
