Charge of Ralph:
Charge = $24 + $33 per hour
Let the time worked be = x.
For x hours, the cost = 33*x = 33x
Charge = 24 + 33x
24 + 33x = 189
33x = 189 - 24
33x = 165
x = 165/33
x = 5
The job took 5 hours.
I hope this helped
4 consecutive odd numbers....x, x + 2, x + 4, x + 6
2(x + x + 2) = 3(x + 4 + x + 6) - 40
2(2x + 2) = 3(2x + 10) - 40
4x + 4 = 6x + 30 - 40
4x + 4 = 6x - 10
4x - 6x = -10 - 4
-2x = - 14
x = -14/-2
x = 7
x + 2 = 7 + 2 = 9
x + 4 = 7 + 4 = 11
x + 6 = 7 + 6 = 13
ur numbers are : 7,9,11,13 <==

Where <em>r </em>is the radius and θ is the central angle, in degrees.
The windshield wiper has a radius of 20 inches and a central angle of 150°. Hence:
Use a calculator:
Our answer is A.
It would be 13 becsue 12.5 time 2 = 25 so round that it = 13
