20% off
100-20=80
find 80% of 179
percent mean psarts ouf o 100
80%=80/100=0.8
'of' means mutipy
80% of 179=
0.8*179=143.2
saleprice=$143.20
Answer:
See Below
Step-by-step explanation:
The left side of the equation HAS TO BE GREATER THAN 3
So we take each ordered pair (x,y), plug it into the expression of left side of inequality and see which one is GREATER THAN 3. That's our answer.
A:
0.5x - 2y
0.5(-2) -2(0.5) = -2
NO
B:
0.5x - 2y
0.5(2) -2(1) = -1
NO
C:
0.5x -2y
0.5(2) -2(-1) = 3
NO
D:
0.5x -2y
0.5(-2) -2(-0.5) = 0
NO
None of them are solutions. C would have been a solution if the inequality had an "EQUAL SIGN" -- but it doesn't. Maybe the question is wrong, but if the question is right, then there is no correct answer.
Answer:
m∠QPR = 35° m∠QPM =40° m∠PRS = 30°
Step-by-step explanation:
ΔPRQ is a right triangle with right angle at R. So m∠QPR = 90 - 55 = 35
ΔQPM is a right triangle with right angle at M. So m∠QPM = 90 - 40 = 40
Arc RQ = 2(35) = 70 and arc SR = 2(25) = 50.
So arc PS = 180 - (arc RQ + arc SR) = 180 - (70 + 50) = 180 - 120 = 60
Now arc PS is the intercepted arc for ∠PRS.
Therefore, m∠PRS = 60/2 = 30
I used the fact that an inscribed angle has a measure 1/2 the measure of the intercepted arc several times. Also, I used the fact that the acute angles of a right triangle are complementary. And, finally I used the fact that an inscribed angle in a semicircle is a right angle.
I hope this helped.
