Draw a diagram to illustrate the problem as shown below.
The area of triangle acb is
A₁ = (1/2)*20*h = 10h
The area of trapezoid abcd is
A₂ = (1/2)*(20+12)*h = 16h
The ratio A₁/A₂ is
A₁/A₂ = (10h)/(16) = 5/8
Answer:
The ratio of triangle acb to the area of trapezoid abcd is 5/8.
Answer:
40%
Step-by-step explanation:
Original price: $25
Discounted price: $15
Amount of discount: $25 - $15 = $10
The boots sold for $10 less than the original price.
To find the percent discount, we need to find what percent of $25 is $10.
percent = part/whole * 100%
percent = 10/25 * 100%
percent = 0.4 * 100%
percent = 40%

Answer:
Step-by-step explanation:
Given
Let the total probability be 1
Probability that Brian wins a raffle = n/n+2
Probability that Brian does not win a raffle = 1 - Probability that Brian wins a raffle
Probability that Brian does not win a raffle = 1 - (n/n+2)
Probability that Brian does not win a raffle = 
Probability that Brian does not win a raffle =
Hence required fraction is
