O A circular swimming pool has a diameter of 24 ft. and
a water height of 3.5 ft. A pump can fill the pool at a rate
of 1.2 ft? (9 gallons) per minute. About how long will it
take to fill this pool (in hours)?

1. perpendicular

2. parallel

3. perpendicular

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
