Answer:
Step-by-step explanation:
y = (-1/m)x + c
the slope here is -1/m
a perpendicular line will have a negative reciprocal slope...all that means is flip the slope and change the sign.
-1/m....flip the slope....-m/1......change the sign....m/1 which is the same as m
I cant tell u the equation of the line perpendicular, but I can tell u that is has a slope of m.

Answer:
B) 3
Step-by-step explanation:
This is because they are both circles and they each have the same equation for circumference. C=2πr
So that if pi stays x 2 then the perimeter will still be 3 x as big as the smaller circle. Which means it takes 3 full turns as to turn around the perimeter.
Answer: 1/3
Step-by-step explanation:
First right it out:
8/24
Then see what number can go in each number:
8 can go in 8 itself and also it can go in 24
Then divide:
8/8 = 1
24/8 = 3
Then you get your answer:
1/3!!!!
A + c = 181......a = 181 - c
9.3a + 5.8c = 1343.80
9.3(181 - c) + 5.8c = 1343.80
1683.3 - 9.3c + 5.8c = 1343.80
-9.3c + 5.8c = 1343.80 - 1683.3
- 3.5c = - 339.5
c = -339.5 / -3.5
c = 97 <== child ticket sold
