Answer:
Step-by-step explanation:
Subtract 15 from both sides of the equation.
Answer:
sinQ=cosR
Step-by-step explanation:
First we need to find out the measure of ∠R.
The sum of all the angles in a triangle add up to 180. Therefore:
∠Q+∠R+∠S=180
66+∠R+90=180
∠R=180-156
∠R=24°
Since ∠Q≠∠R, sinQ≠sinR. So the first option is incorrect - let's try the second one.
sinQ=cosR
sin66=cos24
0.9135454576=0.9135454576
So the second equation is the correct relation.
A=4πr^2
A=4π12^2
12 ^ 2 = 144
4 * 3.14 = 12.56
12.56 * 144 =1808.64
(Google states it 1809.56 though...)
Answer:
Discounted percent = 42.5% and price of the discounted product compared to original is 57.5%
Step-by-step explanation:
$46 = Discount of some decimal of $80
46 = x(80)
46/80 = 0.575
Change it to percent
57.5% discount
