Answer:
0
Step-by-step explanation:
The question lacks the graph to be able to solve it, I was doing a little research and I could find the graph which I will attach:
Already with the figure we can solve the question.
We have that the average exchange rate in this case would only take the normal slope between those 2 lines
. Furthermore we know that the slope (m) is given by:
m = (y2-y1) / (x2 - x1)
From the graph we have to:
y2 = 0
y1 = 0
x2 = 5
x1 = 3
we replace:
m = (0-0) / (5 - 3)
m = 0
Therefore the average rate is 0.
(1.49+1.29+1.79+0.99)/5+3+6+9= 19.112
Rounding to the nearest cent = 19.11
Answer: He will need 20 feet of fabric .
Step-by-step explanation:
Given: circumference of cushion = 7.85 feet.
Since , circumference = , where r = radius.
Area of each piece =
Area of 2 pieces = 2 x 5 feet = 10 feet
Area for 2 cushions = 2 x (Area of 2 pieces)
= 2 x 10 feet = 20 feet
He will need 20 feet of fabric .
