Answer:
B. 
Step-by-step explanation:
The right triangle altitude theorem states that the altitude of a right angled triangles formed on the hypotenuse is equal to the geometric mean of the 2 line segments it creates.
This can be represented as:
Where,
h = the length of the altitude,
x and y are the lengths of the 2 segments formed.
Therefore, the length of the altitude = 
It took 22 $20 bills . $86 x5= $430
Then $430 divide by 20 = 21.5
So you can’t have half a bill do the answer has to be rounded up to 22 twenty dollar bills
Answer:
Step-by-step explanation:
Use PEMDAS:
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)

The correct answer is: 11
Here’s how you solve it!
You can remove the 0 since when you add or subtract 0 it stays the same.
Then you would want to look at the first set of parentheses (-20)
Since it is -(-20) this changes the sign to a positive +20
9-5+20+(-13)
Now since the + is in front of the (-13) it remains the same.
Now you are left with this:
9-5+20-13
9-5=4
4+20=24
24-13=11
Then you are left with your answer: 11
Hope this helps! :3
