Answer:
C - The cost of fabric compared with its length over time.
1) The formula for finding the area of a trapezoid is (base 1+base 2)*height/2
2) Plug in the information we already have:
(6+6.8)*h/2=32
3) Simplify:
12.8h/2=32
4) Multiply both sides by 2:
12.8h=64
5) Divide both sides by 12.8:
h=5
6) HEIGHT IS 5 IN.
Answer:
y = 0.05x
Step-by-step explanation:
A movie theater sends out a coupon for 95% off the price of a ticket, so the price of the ticket with the coupon is 100% - 95% = 5% of the original price.
Let
x = original price
y = price of the ticket with the coupon
Then
x - 100%
y - 5%
Write a proportion:
Cross multiply:
Since the original price and final price are always greater than 0, then the graph of this equation is in the first quadrant (see attached diagram)
