Betsy has to sell carnival tickets worth at least $60. The price of a child ticket is $5, and the price of an adult ticket is $8. Let x be the number of child tickets sold and y be the number of adult tickets sold. which of the following graphs best models this situation. A) 5x+8y
60
B) 5x+8y
60
C) 5x+8y
60
D) 5x+8y
60

A) 5x + 8y 60

Step-by-step explanation:

"At least" translates to the inequality symbol or "greater than or equal to."

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
