Please help!! A roofing contractor purchases a shingle delivery truck with a shingle elevator for $40,700. The vehicle requires an average expenditure of $8.50 per hour for fuel and maintenance, and the operator is paid $12.50 per hour. Use the formula for profit [P = R − C] to write an equation for the profit derived from t hours of use.

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0

70

the answer is b
