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.
I guess it’s A not sure tho
ANSWER:
The right option is d)
As 5*1=5
5*3=15
5*4=20
HOPE IT HELPS!!!!!
PLEASE MARK BRAINLIEST!!!!
Answer:
Its A because when you do (x-5)=0 you add 5 to get x=5 and thats your x value and the 3 for your k is your y value
Do 142degrees subtract that by 180 that is the angle on the other side then put that answer plus 49 equal to 180 then there is your answer
