Answer:
20/(9π) m/min ≈ 0.707 m/min
Step-by-step explanation:
The rate of change of height is the rate of change of volume divided by the surface area. Of course, the surface area is given by πr², where r = d/2 = 3 m.
dh/dt = (dV/dt)/A = (20 m³/min)/(π(3 m²))
dh/dt = 20/(9π) m/min ≈ 0.707 m/min
Answer:
b) 18
Step-by-step explanation:
600 - 150 = 450
25x = 450
x = 18
check
25 x 18 = 450
450 + 150 = 600
Answer:
the answer will be 0.35
Step-by-step explanation:
If you are trying to state that:
(23 + x) + 19 = 23 + (x + 19), then any number can complete the number sentence.
Because they are the same for both sides, no matter what x is, it will always be equal. (Additive Property of Equality).
hope this helps
