Roni wants to write an equation to represent a proportional relationship that has a constant of proportionality equal to Start F
raction 7 over 25 End Fraction. She writes the equation y = x + Start Fraction 7 over 25 End Fraction. What error is Roni making?
A. She should have written y = negative x + StartFraction 7 over 25 EndFraction so that x and y have a constant sum.
B. She should have written x y = StartFraction 7 over 25 EndFraction so that x and y have a constant product.
C. She should have written y = StartFraction 7 over 25 EndFraction x so that x and y have a constant quotient.
D. She should have written y = StartFraction 7 over 25 EndFraction so that y has a constant value.

Answer:
D. 220.16 Square feet
Step-by-step explanation: The shaded area is the space in the square not filled by the circle. So we need to find the area of the circle. The formula for area of a circle is . So we fill in this equation with the information we already know:
Simplify the exponents
Multiply
So now we know the area of the circle we have to find the area of the square because the circle is inside the square. It is a simple which is 1,024. Since we are looking for the shaded area we will subtract the area of the circle from the area of the square because the circle is not shaded.
1024-803.94= 220.16 square feet
