Area of trapezoid = 1/2(b1+b2)h
b1 and b2 are top and bottom bases
so b1 = 15.8 and b2 = 21.8
h is height so h = 11.7
so
A = 1/2(15.8 + 21.8)(11.7)
A = 1/2(37.6)(11.7)
A = 219.96
answer
D. 219.96 yd^2
Answer:
D. 3b + 2(b + 0.75) = 4.50; $0.60 per pound of bananas, $1.35 per pound of oranges
Step-by-step explanation:
Price per pounds of bananas = b
Price per pound of oranges = b + $0.75
Diego buys:
3 pounds of bananas = 3(b) = 3b
2 pounds of oranges = 2(b + 0.75)
Amount paid by Diego is expressed as:
3b + 2(b + 0.75) = 4.50
To find the price per pound of each fruit, use the equation above to find the value of b:
3b + 2b + 1.50 = 4.50
Combine like terms
5b + 1.50 = 4.50
5b + 1.50 - 1.50 = 4.50 - 1.50
5b = 3
5b/5 = 3/5
b = 0.6
Price per pound of banana = b = $0.6
Price per pound of oranges = b + $0.75
Plug in the value of b
= $0.6 + $0.75
= $1.35
Any number to the power of 0 equals 1. So, we can rewrite the equation as follows:
