Answer:
She used 5.775 pints of white paint to paint her bedroom walls.
Step-by-step explanation:
This question can be solved using a system of equations.
I am going to say that:
x is the amount of white paint used.
y is the amount of blue paint used.
7.7 pints of blue paint and white paint to paint her bedroom walls.
This means that 
1/4 of this amount is blue paint, and the rest is white paint.
The rest is 1-(1/4) = 3/4. That is, the amount of white paint is the triple of the amount of blue paint. That is, 
, or 
Replacing in the first equation:
She used 5.775 pints of white paint to paint her bedroom walls.

Answer:
62.28
Step-by-step explanation:
Ok, so since we know the radius of the circle and the area of the shaded region, we can find the fraction of the whole circle the shaded region is, and apply that to the total circumference to find the length of the arc.
1. area of whole circle = 17^2*3.14 = 907.46in^2
2. 529.35/907.46 = 0.5833314967
3. circumference of whole circle = 2*3.14*17 = 106.76
4. length of arc = 106.76*0.5833314967 = 62.2764705877 --> 62.28
