n/5 = -1/5

5n = -5

<u>n = -1</u>

n - 13 = -12

n = -12 + 13

<u>n = 1</u>

n + 15 = -10

n = -10 - 15

<u>n = -25</u>

-5n = 1

<u>n = -1/5</u>

You want to put a 5 inch thick layer of topsoil for a new 16 ft by 34 ft garden. The dirt store sells by the cubic yards. How ma
shepuryov [24]

Answer: About 8.5 cubic yards

Step-by-step explanation:

Given : The length of the garden = 16 ft.

The width of the garden = 34 ft.

The depth of the thick layer of topsoil on the garden = 5 inch

=\dfrac{5}{12}\text{ ft.}               [Since 1 foot = 12 inches]

The volume of a rectangular prism :-

V=l*w*h, where l is length , w is width and h is height.

The number of cubic feet of topsoil required will be

V=16\times34\times\dfrac{5}{12}=\dfrac{680}{3}\text{cubic feet}

Since 1 yard = 3 feet

1\text{ foot}=\dfrac{1}{3}\text{ yard}

V=\dfrac{680}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}\times\dfrac{1}{3}=8.3950617284\approx8.50\text{cubic yards}

A cylindrical can is to have volume 1500 cubic centimeters. determine the radius and the height which will minimize the amount o
Degger [83]
Assuming R and H:
So volume is pir^2 * H = 1500 and H = 1500/(pir^2)  while surface area is A= 2pir*H + 2pir^2 
A = 2pir(r+h)= 2piR^2 + 2pir*1500/(pir^2)= 2piR^2 + 3000/r
For A to take minimum, get the derivative 4pir - 3000/R^2 and let it be 0 
4pir^3 - 3000 = 0 
r = cbrt(3000/(4pi)) ≈ 6.20
h = 1500/(pi(6.20)^2) ≈ 12.42
