Answer: x = - 7
Step-by-step explanation:
Square foot is a unit of area. find the area of the manhole. A = (pi)r^2
9.2 lbs per square foot multiplied by area in units of square feet gives lbs.
diameter is twice radius, so radius is 1.5 ft.
Area of manhole = (pi)(1.5)^2
lbs manhole = (9.2)(pi)(1.5)^2
= 65 lbs
Answer:
The length and width of the prism are 20 metres and 5 metres respectively
Step-by-step explanation: given that the length of a rectangular prism is four times its width. That is
Length L = 4 width W
L = 4W
the volume of the prism is 380 cubic meters
V = L × W × H
380 = 4W × W × H
380 = 4W^2H
W^2H = 380/4
W^2 H = 95
The only way to get a perfect square number is to make H = 3.8
3.8W^2 = 95
W^2 = 95/3.8
W^2 = 25
W = 5
But L = 4W
L = 4 × 5 = 20
The length and width of the prism are therefore 20 metres and 5 metres respectively
Answer:
y = 27
Step-by-step explanation:
If m=11, x=2, and b=5, then:
y = mx + b
Plug in the values into the linear equation:
y = 11(2) + 5
y = 22 + 5
y = 27
