45% of 20 is going to be 9
Answer:
The volume of the inflated beach ball is 13734in³
Step-by-step explanation:
We know that the formula to calculate the volume of a sphere is
v = 3/4 * π * r³
π = 3.14
r = 18in
we replace the values and calculate the volume of a sphere
v = 3/4 * 3.14 * (18in)³
v = 3/4 * 3.14 * (5832in³)
v = 13734.36 in³
the nearest whole number
13734in³
Answer:
3/4
Step-by-step explanation:
f(0) - f(3) / 0 - 3
f(0) = -4
f(3) = 9/4 - 16/4 = -7/4
f(0) - f(3) = [-4 - (-7/4)]
f(0) - f(3) = [-16/4 + 7/4]
f(0) - f(3) = -9/4
-9/4 ÷ -3 = -9/4 · -1/3 = 3/4
Answer:
10*5 = 50
10*4 = 40
5 * 4 = 20
The total is 110 but we can't forget there are 2 sides to each of those planes and so the area = 220 square meters
Step-by-step explanation:
<u>C. 42 units</u>
Step-by-step explanation:
I have attached a diagram to help you understand this problem. By looking at the diagram you can see that AE is half of BD, and that BD will be equal to AC. So we need to figure out the length of line BD to get AC.
To do this, you will multiply the length of AE by 2 and set it equal to BD.

Then distribute, multiply what is in the parentheses by 2.

Subtract 4x from both sides.

Subtract 2 from both sides.

x = 8
Now that we have x, we can plug it into the equation to find BD.

BD is equal to 42 units, so we know...
<u><em>AC = 42 units</em></u>
