Answer:
15 - 5 = 10 wow that was so hard
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.
The answer should be 2x-2
Do 24 times 9
This equals 216 square feet
Answer:
660
Step-by-step explanation:
20 * 8 = 160
25,000 * 2% = 500
500 + 160 = 660
Therefore your answer is 660
