Answer:

Time taken to fill the pool = 7.81 hours

Step-by-step explanation:

We are given that it takes 19 seconds to fill 2 gallons. Therefore, we can use cross multiplication to know how long will it take to fill one gallon as follows :

Time taken to fill 2 gallons of tank = 19 seconds

\text{Time taken to fill 1 gallons of tank = }\frac{19}{2}\text{ = 9.5 seconds}

Therefore, it takes 9.5 seconds to fill one gallon of water.

One gallon is equivalent to 0.133681 cubic feet

Therefore, it takes 9.5 seconds to fill 0.133681 cubic feet

Now, to find Volume of the pool :

radius of pool = 6 ft

volume of pool = pi × (radius)² × height

volume of pool = 3.14 × 6² × 3.5 

volume of pool = 395.64 cubic feet

Time taken to fill 0.133681 cubic feet of water = 9.5 sec

\text{Time taken to fill 395.34 cubic feet of water = }\frac{9.5}{0.133681}\times 395.64\\\\\implies\bf\textbf{Time taken to fill the pool = 28116.04 seconds}=\frac{28116.04}{60\times 60}\text{ hours}\\\approx 7.81\textbf{ hours}

Hence, Time taken to fill the pool = 7.81 hours

Mr. Nolan has a bank account that compounds interest
german

Answer: At the end of the day on December 8, he has a total balance of $2841.02

Step-by-step explanation:

The rate at which the compound interest adds up is a 3.7%.

His principal is $2644.08, on the 7th of December, he withdraws $550. Thus, his balance is = $2644.08 - $550 = $2094.08.

He later deposits $934, after being paid by his employer.

That is $2094.08 + $934 = $3028.08

Which is his balance at the end of the day on December 7.

Remember that the rate is daily, at a 3.7%.

A 3.7% of the balance of December 7, $3028.08 is $112.039.

In total, interest +amount = real balance,

$112.039+$3028.08 = $3140.119

He later withdraws $300 for holiday shopping = $3140.119 - 300 = $2840.119

But 1 dollar = 100 cents and vice versa.

Therefore, $2840.119 = $2841.019

In two decimal places, that is approximately $2841.02

Therefore, Mr Nolan's balance at the end of December 8 is $2841.02.
