Answer:
57
Step-by-step explanation:
The volume of a cone is given by the formula ...
V = (1/3)πr²h
For a pile with a radius of 8.5 m and a height of 9 m, the volume is ...
V = (1/3)π(8.5 m)²(9 m) = 216.75π m³ ≈ 680.94 m³
Then the number of truckloads required to create that size pile will be ...
(680.94 m³)/(12 m³/truck) = 56.745 trucks
Even a partial truck load entails another trip, so ...
57 truck loads of sand are needed.

the arrows point from the x coordinate to the y coordinate in each in pair
Answer:

Step-by-step explanation:
Complementary angles are two angles that add up to 90°.
We know the measurements of m∠ZA and m∠ZB, so their angle measures will add to 90°.

Let's simplify this equation so we have x on one side of the equation.

Now that we know the value of
, we can substitute it inside the equation for m∠ZB (
)
