Answer
a decrease of 0.2 gallons per second
Explanation
The drain was open for 30 seconds.
The water that ran out for 30 seconds = 20 - 14
= 6 gallons
Rate of decrease = (change in gallons)/(time taken)
= 6/30
= 0.2
The rate of change in the amount of water remaining in the tub per second will be the same as the one that ran out since the outlet is the same.
So the correct answer from the choices is "a decrease of 0.2 gallons per second".
Answer:
The compound interest is Rs8275
Step-by-step explanation:
The rule of the compound interest is A = P
, where
- r is the interest rate in decimal
- n is the number of periods
The interest I = A - P
∵ The amount of investment is Rs25000 for 3 years
∴ P = 25000
∴ t = 3
∵ The rate of interest is 10% per annum, compounded annually
∴ r = 10% = 10 ÷ 100 = 0.1
∴ n = 1 ⇒ compounded annually
→ Substitute these value in the 1st rule above to find the new amount
∵ A = 25000
∴ A = 25000
∴ A = Rs33275
→ Use the 2nd rule above to find the interest
∵ I = 33275 - 25000
∴ I = 8275
∴ The compound interest is Rs8275
