Peter paid $12.83 for a dvd. the price of the dvd was $11.99. how much sales tax did peter pay?

$0.84 or 84 cents

Step-by-step explanation:

Peter paid $12.83 for a DVD even though the price of the DVD player was $11.99.

To get the amount of sales tax Peter paid, we would subtract the price of the DVD player from the price paid by Peter. This will give:

=$12.83 - $11.99

= $0.84

Since 100 cents make a dollar, this will be: $0.84 × 100

= 84 cents

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
