Billy goes to the store. he has $90. he wants to purchase a leather jacket for $45, a hat for $10, and the rest on jeans. each pair of jeans cost $35. write an inequality for the number of jeans he can purchase

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
