YZ = YA + AZ
41.5 = 5.5 + AZ
AZ = 41.5 - 5.5
AZ = 36
So, your final answer is AZ = 36
Hope this helps!
5.3 minutes.
First, let's calculate the volume of the tank. That will be the area of the base multiplied by it's length. And since it's base is a circle, the area is pi*r^2. So:
V = l*pi*r^2
V = 3.5 * pi * (2.2/2)^2
V = 3.5 * pi * (1.1)^2
V = 3.5 * pi * 1.21
V = 4.235 * pi
V = 13.30464489
So the tank has a volume of about 13.3 ft^3. Now simply divide that volume
by the rate of incoming fluid. So
13.3 / 2.5 = 5.32
Rounding to 2 significant figures gives a time of 5.3 minutes.
If you have two numbers x, y. The geometric mean is: √xy
For 4 and x. Geometric Mean = √4x and this is equal to √6
√4x = √6 Square both sides. The square root disappears.
4x = 6
x = 6/4 = 3/2 = 1.5
The other number is 1.5.
