Answer: 2
Step-by-step explanation:
x = 4
because it is perpendicular, the new equation has to be a vertical since the original was horizontal. We know that it passes through (4,-2) so it has to be x=4
C=2x Pi x R so 2x3.14x17.5 = 109.9
Answer:
40%
Step-by-step explanation:
So 10/25=0.4
0.4=40%
45 = 90% * x
45 = .90x
45/.90 = x
x = 50
45 is 90% of 50
