Answer:-8w^2x^2-4wx^2+60x^2
Step-by-step explanation:
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.
In order to find the solution you must calculate the mean, or the average by adding the numbers together and dividing by how many numbers there are.
5.5 + -3.6 + 12.8 = 14.7
14.7 ÷ 3 = 4.9
4.9 is Molly's average score.
