My brother wants a new pair of the Jordan Aerospace 720s. They are currently $200, but he has a coupon for 15% off. If he uses the coupon, how much will he pay before sales tax

$170

Step-by-step explanation:

15% off means you pay 85% of the original price.

To find the price you will pay take the original price $200 and multiply that by .85 to figure out how much you will pay.

200 x .85 = $170

your brother will have to pay $170 before sales tax because %15 of $200 is $30 so then you subtract $30 from $200 and you get $170

Step-by-step explanation: Step 1: you use a calculator or ask google what %15 of $200 is.

Step 2: you the subtract $30 from $200 and you get $170.

Step 3: you verify your answer by asking an adult and then by searching it up on google.

something that characterises a right triangle is the fact that we may use pythagoras' theorem to find any one of its sides given that we have the length of the other two sides. here, we have the length of the hypotenuse, √(87) yd, and one other side, √(23) yd, thus we can easily find the length of the remaining side using pythagoras' theorem as defined below:

c^2 = a^2 + b^2, where c is the length of the hypotenuse, and a and b are the lengths of the other two sides.

thus, given that c = √(87) and a = √(23), we may substitute these into the formula we defined above to get:

c^2 = a^2 + b^2

(√87)^2 = (√23)^2 + b^2 (substitute c = √87 and a = √23 into the equation)

87 = 23 + b^2 (evaluate (√87)^2 = 87 and (√23)^2 = 23 - remember that the square root of a number, squared will equal that very same number)

64 = b^2 (subtract 23 from both sides)

√64 = b (take the square root of both sides)

8 = b (evaluate √64 = 8)

therefor, the length of the unknown leg in the right triangle is 8 yd (first answer).

1/3 + 1/5 = 8/15.
