Well, since it has 2 zeros, you move the point 2 places to the right.
Answer:
x = 2
Step-by-step explanation:
2x - 10 + 3x - 15 = 10
5x - 25 = 10
5x = 35
x = 7
7 - 5 = 2
4 hours=240 minutes
240 minutes=5 1/3 45 min. intervals
5 1/3 x 6 = 16/3 x 6 = 32
The staff can prepare 32 tables in 4 hours
Answer:
The coordinates of the vertex are
(-5;-9)
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.
