Pls help!! An electrician charges $75 per visit plus $25/h for house calls.

A) write an algebraic expression that describes the service charge for one household visit.

B) use your expression to find the tot service charge for a 3.5 hour repair job.

C) suppose all charges are double for evening, weekends, and holidays. Write a simplified expression for these service charges.

hope this !

step-by-step explanation:

d = distance between moon and sun, which in this problem is the hypotenuse of a right triangle.  

the distance y is the side opposite to angle x in the right triangle.   use the definition of the sine function from basic trigonometry.

sin(x) = y/d ⇒

d = y/sin(x)

i would be 2,000 just get the square root of 50 which is 2500 and the divid 4/5 and last thing multiply the answer you get for that by the square root of 50
