Correct question:
Joanie uses 6.4 pints of blue paint and white paint to paint her bedroom walls. ³/₄ of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
The quantity of white paint she used to paint her bedroom walls is 1.6 pints
Step-by-step explanation:
Given;
total quantity of blue paint and white paint used by Joanie = 6.4 pints
she uses ³/₄ of the total quantity of the paints as blue
the remaining fraction as white paint = 1 - ³/₄ = ¹/₄
The fraction of the total quantity of paints that is white paint = ¹/₄
And,
The quantity of white paint she used to paint her bedroom walls = ¹/₄ x 6.4 pints = 1.6 pints
Then, quantity of blue paint she used = ³/₄ x 6.4 = 4.8 pints
<u>Check:</u>
blue paint + white pain = total
4.8 + 1.6 = 6.4 pints
Therefore, the quantity of white paint she used to paint her bedroom walls is 1.6 pints

Answer:
486 sq. in
Step-by-step explanation:
Find the area of one face
Area = s^2
s = 9 in
Area = 9^2
Area = 81
Area 6 sides
There are 6 sides to a cube. So if you have the area of 1 side, you need only multiply by 6 to get the area of the cube
Area = 6 * 81
Area = 486
