After a heavy rainstorm, Barbara's dog left muddy paw prints all over her back patio. She decided to rent an electric
pressure washer to clean up the mess. The piecewise function below shows the rental charges for the pressure washer,
dependent upon how many hours she rents it. Due to high demand, you cannot rent the washer for more than 24 hours at
time. Barbara's brother asked to use the washer and agreed to pay Barbara for any additional monies owed.

her brother owe her?

option (b) is correct

step-by-step explanation:

to find the solution of this system, we need to convert it into reduced row-echelon form. we have,

after applying row operations r2 -> r2/2 and r3 -> r3/3, we get,

11.2

step-by-step explanation:

when doing tangent the tangent of the angle is equal to the opposite side from the angle over the adjacent side to the angle.

tan43 = x / 12

move 12 over by multiplying each side by 12

12tan43 = x

x = about 11.2

0.0076, if you meant 4.125 divided by 0.03125 it would be 132

step-by-step explanation:

first you have to move the decimal in 0.03125 over until its behind the 5 which is 5 places over. now the number is 3125

then you have to move the decimal in 4.125, 5 places over. now the number is 4,112,500.

now you divide like you would normally would and get 0.0076
