What is the height of a rectangle when I base is 8 ft and the area is 30 ft
ZanzabumX [31]
To do this you have to fill in the equation base*height=area, but you don't know the height, so we'll use h for height. Plugging in the numbers you gave me, the equation is: 8*h=30. To solve this, we need to find h. To find height you do \frac{area}{base}. Doing this, we get h = 3.75 ft.

Hope this helped!

DanielleElmas [232]

Answer:

$432.18

Step-by-step explanation:

Time and a half = 50% more pay rate / 1.5*6.86 = $10.29 per hour

Double time = 2*6.86 = $13.72 per hour

Rest of the time => At regular rate

Total Amount = 10(10.29) + 4(13.72) + (54 - 10 - 4)(6.86)

                       = 10(10.29) + 4(13.72) + (40)(6.86)

                       = $ 432.18
