Step-by-step explanation:
Subtract the discount percentage from 100%. Multiply the difference by the original price to get the sale price. For example, given a 10% discount applied to a list price of $50.00, subtract 10% from 100% = 90%. Multiply the list price $50.00 by 90% = $45.00, which is the sale price. Hoping this helps.
15. s = 10 because in a 45-45-90 degree triangle the longer and shorter leg have the same distance, r = 10√2 because the hypotenuse in a 45-45-90 degree triangle is √2 times the same variable as the longer and shorter leg
16. n °= 30° because it is a 30-60-90 triangle I knew that it was 30 degrees, 2n° = 60° because variable n equals 30 degrees and two times 30 equals 60, q = 15√3 I followed the formula of a 30-60-90 degree triangle that states the longer leg is equal to √3 times the shorter leg, p = 15 I got this answer because the hypotenuse (which is 30) is two times the shorter leg so all I had to do was divide by two to get 15 (the shorter leg)
17. Couldn't see got cut off.
18. c = 12 I saw that the square was made up of 4 congruent triangles and I noticed that one triangle had its hypotenuse given. I noticed that this triangle was a 30-60-90 degree triangle so I took 24 (the hypotenuse) and divided it by two to get 12 because the hypotenuse is two times the shorter leg. Next I looked at where variable c was and since all the triangles are congruent I saw that It was the shorter leg and I took the 12 that I found in the former triangle to get the answer c = 12.<span>
*I also suggest you look up on google "special right triangle formulas"</span>
The discount is 20%.
16 x 3 = $48.00 regular price for 3 CDs
$48.00 - $38.40 = $9.60
$48.00 x 20%
48 x .20 = 9.6
Hope this helps. :)
