Answer:
5.14
Step-by-step explanation:
b. 8 because Total Pieces Sold=60
Pieces contributed by the cafeteria=20
Pieces contributed by the clubs=x
We can solve this problem by creating an equation to relate these terms:
Total Pieces Sold= (pieces contributed by the cafeteria) + (pieces contributed by the clubs)
Our equation is therefore: 60=20+x. We solve for x:
60-20=x
40=x
This means the clubs contributed 40 pieces. To find out how many pies that equals, we can use the relationship:
(40 pieces)/(y pies) = (5 pieces)/(1 pie). Solve for y:
(1)(40)=(5)(x)
(40/5)=8
Answer:
feet, or 14.14 feet
Step-by-step explanation:
Use the arc length formula:
s = rθ
To use the formula, we have to convert the central angle to radians.
90° is equivalent to 
radians, so plug this and the radius into the formula:
s = rθ
s = (9)()
s =
So, the length of the arc is 
feet, or approximately 14.14 feet
