Answer:
You need to get a 95 on the next test to have a 90 grade average.
Step-by-step explanation:
(85 + 90 + n)/3 = 90
<u>Step 1: Multiply both sides by 3</u>
(85 + 90 + n)/3 * 3 = 90 * 3
85 + 90 + n = 270
<u>Step 2: Subtract 85 from both sides</u>
85 + 90 + n - 85 = 270 - 85
90 + n - 90 = 185 - 90
n = 95
Answer: You need to get a 95 on the next test to have a 90 grade average.
Answer:
C
Step-by-step explanation:
The question states he wants to show the relationship between the trees ages and the number of apples they produce.
An hemispherical dome is half a sphere. If the diameter is 60 m, then the radius is 30 m.
We can use differentials to solve this problem because we are adding a thin layer to the original dome, so the volume of the dome in increased by a differential of itself.
This differential volume that the dome is increased is equal to the volume of the coat of paint.
The volume of the dome can be written as:

Now, we can calculate dV as:

Answer: the paint needed for this coat is approximately 7.92 m^3
