Well 120 is 1/3 of the square so the 9ft is 2/3 of the square so it is B
B they only have one pair of parallel sides. The top and bottom
Answer: $4902
Step-by-step explanation:
Amount = P (1 + rt)
= 4300 (1 + .02 * 7)
= 4300 (1 + .14)
= 4300 (1.14)
= 4902
Answer:
The water level is dropping at a rate of 0.24 ft/s
Step-by-step explanation:
Here, we simply want to calculate the change in depth (height of the cone) , given the volume change
Mathematically, we have the volume of a cone as;
V = 1/3 * π * r^2 * h
we are given dv/dt as 12 ft^3/m
dv/dh = 1/3 * π * r^2
Substituting the value for the radius, we have
dv/dh = 1/3 * 22/7 * 4^2 = 50.29
dh/dt = dh/dv * dv/dt
dh/dv = 1/(dv/dh) = 1/50.29
Thus,
dh/dt = 1/50.29 * 12
dh/dt = 0.24 ft/s
