Arc length is figured by the following formula theta/360 x 2pi(r) input the knowns 30/360x2pi(20)=11.52 miles
To solve, set an equation:
472=0.8x
Divide both sides by 0.8
472/0.8=0.8x/0.8
x=590
Answer: The original price was $590
Expression B results in a positive number

You can't. There are an infinite number of different parallelograms,
with different dimensions, that all have area of 96 square miles.
Knowing the area doesn't tell you the dimensions.
Here are a few parallelograms with areas of 96 square miles:
-- square, every side 4√6 miles long
-- rectangle, 12 miles long, 8 miles wide
-- parallelogram, base=32 miles, height=3 miles
There are an infinite number of others.
Hello!
Since this is a reflection, then the new figure has to be congruent since we're not changing the size or the shape.
Now, (x, y) is located in the First Quadrant, whereas (x, -y) is located in the Fourth Quadrant. If we're going from the First Quadrant to the Fourth Quadrant, then this has to be a reflection across the x-axis.
The correct answer is "Yes, ΔP'Q'R is a reflection of ΔPQR over the x-axis." :)
