To find the width, divide the area by the length.
Width = 375 / 25
Width = 15 feet.
Length: 6 Width: 2 Area: 12
27 1/4 = 27.25
27.25 * 5.15 = 140.34
140.34 - (6.19 + 10.74 + 6.37) =
140.34 - 23.30 =
117.04 <== net pay
We already know that the hourly rate for John is : 1/6 and the hourly rate for Rick is : 1/8. What we don`t know is a hourly rate for Molly and we will call it 1 / x.
The hourly rate for all together is: 1 / 3
An equation is:
1 / 3 = 1 / x + 1 / 6 + 1 / 8
1 / 3 = 1 / x + 4 / 24 + 3 / 24
1 / 3 = 1 / x + 7 / 24
1 / x = 1 / 3 - 7 / 24
1 / x = 8 / 24 - 7 / 24
1 / x = 1 / 24
1 / 3 = 1 / 24 + 1 / 6 + 1 / 8
The hourly rate for Molly is 1 / 24. Molly can paint the room alone for 24 hours.
Answer: x = 20.
Step-by-step explanation:
x and (3x + 10) combine to form a right angle, shown in the diagram by the small square joining the perpendicular lines.
Right angles are 90 degrees, so you can add both angles to get 90:
