Answer:
4,200 liters
Step-by-step explanation:
The flow rate is given by:

Integrating the flow rate expression from t=0 to t=30 minutes, yields the total volume that flows out of the tank during that period:

4,200 liters of water flow from the tank during the first 30 minutes.
Answer:
(6b+4)/r=t
Step-by-step explanation:
b=(rt-4)/6
multiply by 6
6b=rt-4
add 4
6b+4=rt
divide by r
(6b+4)/r=t
I am quite sure that it is B: Temperature

Answer: 6.93</h3>
Work Shown:
Use the pythagorean theorem to find x
a^2 + b^2 = c^2
x^2 + 11^2 = 13^2
x^2 + 121 = 169
x^2 = 169 - 121
x^2 = 48
x = sqrt(48)
x = 6.92820323027551
x = 6.93
