Let the weights of the two candies be repres. by x and y.
Then x + y = 60, or x = 60 - y
($1.16 / lb) x + ($0.86 / lb) y = ($1.00 / lb) (60 lb) = $60
Then 1.16(60-y) + 0.86y = 60
69.6 - 1.16y + 0.86y = 60 9.6
9.6 = 0.3y Solving for y, y = ------- = 32 lb
0.3
Then x = (60-32) lb = 28 lb
120 is good engough if you dont kn o
Answer:
I need to see the data set and graph to be able to help you more
Step-by-step explanation:
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
