Answer: The amount of water is 4200 liters during the first 30 minutes.
Step-by-step explanation:
Since we have given that
Water flows at the rate of
liters per minute.
Here, t is the number of minutes
We need to find the amount of water that flows from the tank during the first 30 minutes.
So, t = 30.
So, our equation becomes,
Hence, the amount of water is 4200 liters during the first 30 minutes.
9x^2 -c =d
add c to each side
9x^2 = c+d
divide by 9
x^2=(c+d)/9
take the square root on each side
x = +- sqrt ((c+d)/9)
simplify
x = +- 1/3 sqrt (c+d)
Answer: 1/3 sqrt (c+d), - 1/3 sqrt (c+d)
