Draw a diagram to illustrate the problem as shown below.
The area of triangle acb is
A₁ = (1/2)*20*h = 10h
The area of trapezoid abcd is
A₂ = (1/2)*(20+12)*h = 16h
The ratio A₁/A₂ is
A₁/A₂ = (10h)/(16) = 5/8
Answer:
The ratio of triangle acb to the area of trapezoid abcd is 5/8.

Answer:
$126.5
Step-by-step explanation:
45.18+18.07=67.25
67.25*2=126.5
Answer: 
Step-by-step explanation:
The formula for calculate the volume of a cylinder is:

Where "r" is the radius and "h" is the height.
Make the conversion from inches to feet. Since
,you get:

So in this case you can identify that:

Then, substituting them into the formula and simplifying you get:

Therefore, the expression for the volume of L feet of drainage tubing, in cubic feet is:

Answer:
69
Step-by-step explanation:
All the given arcs cover the entire circle circumference, so their measures add up to a full 360.
(2x - 16) + (x + 40) + x + 60 = 360
4x + 84 = 360
4x = 276
x = 69
