6 thousand less than 37,215
6000 less than 37,215 is basically subtracting.
37,215 - 6000 = 31,215
On problems ii, and iii, you just count up the amount of sides on the polygon and add x behind it to create a type of an equation to find the perimeter of that shape that will work as longs as the sides are congruent to each other.
For problems a,b, and c, you just have to calculate what x is. On a, you find what the other side is if one side is 2 and the area is 24. On b you find what the other side could equal if one side is 4 and the area is 16. On c you know what the perimeter is (72) . The longer sides are 2x and the shorter sides are x. SO you divide by the #s and check your work!
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:
15 days
Step-by-step explanation:
Well, since there are 5 cups of oatmeal, and she eats 1/3 a day, then the equation is: 5 divided by 1/3 then change 1/3 to its reciprocal which is 3. 5 times three is 15 so therefore Stella will finish it in 15 days.
