The expression 0.09x+(x-30) models the final price of a bicycle is its an instant rebate in a state that charges a sales tax. the tax is on the original price. which expression represents the amount of tax that is paid on the bicycle? a)0.09x b)1.09x c)x-30 d)0.09x-30

A)0.09x

Step-by-step explanation:

The original price of the bicycle is x.

The discounted price of the bicycle is x - 30. It is a $30 discount.

The tax goes on the original price. 0.09x is the 9% tax applied to the original price x.

0.09x

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
