I think that this is right, but I assumed that the ceiling has the same dimensions as the wall you would need 4 gallons for 2 coats.
Work:
20x8= 160 (square feet for 1 wall)
160x5=800 (i assumed there are 4 walls and 1 ceiling)
800x2=1600 (you need 2 coats)
1600/400=4 (each gallon includes 400 square feet)

Gnom [1K]

Answer:

15 yds

Step-by-step explanation:

12 in = 1ft

3 ft = 1yd

to convert

540 in * 1ft/12 in   * 1yd /3 ft = (540 * 1 * 1)/ (12*3) = 540/36 =15 yds

all the units canceled except for yds

Find the area of the unshaded part of the figure
Tcecarenko [31]
<h3>Answer:</h3>

  unshaded area = 25(4 -π) in^2 ≈ 21.46 in^2

<h3>Step-by-step explanation:</h3>

Each of the shaded circles has a diameter of (20 in)/4 = 5 in, which also is the width of the enclosing rectangle. Then each circle has a radius of 2.5 in, and an area of ...

  A = πr^2 = π(2.5 in)^2 = 6.25π in^2

The four circles together have an area of ...

  4A = 4·(6.25π in^2) = 25π in^2

The area of the rectangle is the product of its length and width:

  A = LW = (20 in)(5 in) = 100 in^2

Since the circles are shaded, the unshaded area is the difference between the rectangle area and the total area of the four circles:

  unshaded area = (100 in^2) - (25π in^2) = 25(4 -π) in^2 ≈ 21.46 in^2

Answer:

x = 2/3

Step-by-step explanation:

cross multiply

-9(x-4) = 10(3x+1)

and then solve the equation

-9x + 36 = 30x + 10

36 = 39x + 10

26 = 39x

x = 2/3
