The rate at which the height of the water in this cylindrical tank is increasing is 26.18 m/mn.
<h3>How to calculate the volume of a cylinder?</h3>
Mathematically, the volume of a cylindrical tank can be calculated by using this formula:
V = πr²h
Where:
Differentiating with respect to h, we have:
dV/dt = πr²(dh/dt)
3 = 3.142 × 5² × dh/dt
3 = 78.55dh/dt
dh/dt = 78.55/3
dh/dt = 26.18 m/mn.

Answer:
9 birds
Explanation:
f is finches, h is herons, w is warblers, t is total
f+h+w=t
All but 6 means subtracted from the total
f=t-6
h=t-6
w=t-6
Adding the three equations gets 3t-18 and plug that back in and isolate
t=3t-18
t= 9

Answer:
Tax multiplier = 3
Explanation:
Given:
Current MPC = 0.75
Find:
Tax multiplier
Computation:
Tax multiplier = MPC / [1 - MPC]
Tax multiplier = 0.75 / [1 - 0.75]
Tax multiplier = 0.75 / 0.25
Tax multiplier = 3
