The property is distributive property
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.
Answer:
70.6% decrease
Step-by-step explanation:
4250-1250 = 3000
4250x = 3000
x=70.6%
70.6% decrease

Answer:
12.6
Step-by-step explanation:
The question requires you to estimate the product of 0.12 * 105
12/100 * 105 ----multiply 12 and 105
12 * 105 = 1260
Divide the answer by 100
1260/100 = 12.6
All the angles in a circle equal to 360 degrees. So basically just add up all the known values: 23+23+15=61 and then subtract that from 360: 360-61=299.
You can also do 23+23+15+x=360. Adding it all becomes 61+x=360, subtract 61 from both sides of the equation, and you get x=299.
(Something to help remember is that the angle is obtuse, meaning it’s automatically more than 90 degrees, hope this helps!)
