"The two pumps working together would pump out water at a rate of 100 gallons per minute. To determine the time it takes to completely pump out the water from the basement, we need to determine the volume of the water in the basement. The dimensions of the basement is 40 feet by 50 feet (given elsewhere) while the depth of the water is said to be 16 inches. From these dimensions, we can calculate for the volume as follows:"
V = length x width x depth
length = 50 feet
width = 40 feet
depth = 16 inches ( 1 foot / 12 inches ) = 1.33 feet
V = 50 x 40 x 1.33 = 2666.67 ft^3 = 19948.05 gal
Time = V / rate
Time = 19948.05 gal / 100 gal / min
Time = 199.48 min
The following system of equations is independent
It would be D. Vertical angles are congruent therefore, b + 56 = 5b. you subtract b from each side which would leave you with 56 = 4b. You divide each side by 4 and you would get 14.
I believe the answer is 0.44444.......
Given:
Amount after three years = $10000
Rate of interest = 8.2 percent compounded monthly = 0.082
Time = 3 years
To find:
The principal value.
Solution:
Formula for amount is
where, P is principal, r is rate of interest, n is the number of times interest compounded in an year, t is number of years.
Substitute A=10000, r=0.082, n=12 and t=3 in the above formula.
Divide both sides by 1.27783.
Therefore, today she have to deposit $7825.767.
