Jodie wants to buy a shirt regularly priced at $20. the shirt is on sale for 15% off the regular price. which equation can be used to determine s , the sale price of the shirt, not including tax? a s = 20 – (20)(0.15) b s = 20 – (20 + 0.15) c s = 20(0.15) d s = 20 + 0.15

it's A

Step-by-step explanation:

you toke the price and times it by the decimal of the discount

0.150 x $20 = $ 3.00.

Step-by-step explanation:

You want to buy something that costs $20, and it's on sale for 15% off. What is the item's sale price?

First, convert the 15% to a real mathematical number. For percents, this is always done by dividing the 15% by 100%, or 15% / 100% = 0.150.

Second, find out what 15% of $20 is. This is the amount of the sale discount. This is always found by mulitplying 0.150 by the item's cost $20. So for this sale, you'll save $ 3.00 on this item.

This means, the cost of the item to you is $17.00$

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
