Answer:
500 in^3
Step-by-step explanation:
The volume of a sphere is given by
V = 4/3 pi r^3
Using 3 for pi
V = 4/3 (3) (5)^3
V = 4 * 125
V = 500
Answer:
6/5 or 1 and 1/5
Step-by-step explanation:
To do this you need to multiply 6/1, 2/3, and 3/10 all together by cancelling out the numerator in 3/10 and the denominator for 2/3. Then you would be left with 6*2*1/10
This simplifies to 6*1/5 because of the 2*1/10 is 1/5, because 1/5 doubled is 1/10.
then multiply the numerator and 6 together to get 6/5.

Answer:
5.5 minutes
Step-by-step explanation:
Fill in the given information and solve for t.
75 = -15cos(2πt/15) +65
-10/15 = cos(2πt/15)
t = 15/(2π)arccos(-2/3) ≈ 5.492
The volume reaches 75 dB about 5.5 minutes after the truck arrives.
