Divide 42 inches by the total amount of inches in one brick
why you are dividing by 42 inches is because 3 1/2 ft is equal to 42 inches
Answer:
33 feet
Step-by-step explanation:
Use SOHCAHTOA to determine which trigonometric function to use:
sin(65)=30/x
sin(65)x=30
x=30/sin(65)
x=33.1
So the length of the ladder rounded to the nearest foot is 33 feet
Total salary = 909.50
Out of this, overtime salary was = 229.50
Normal salary for 40 hours was = 909.50 - 229.50 = 680
Hourly rate = 680/40 = 17
Overtime is time and half = 17 + 17/2 = 17 + 8.5 = 25.5
Number of overtime hours = 229.50/25.5 = 9 hours
