Answer:
66.56 cm
Step-by-step explanation:
First, let's find the circumference of a circle with radius 8 cm.
2 * 8 * 3.14 = 50.24
Now, since we only need a 1/4 of the circumference, divide that number by 4
50.24 / 4 = 12.56
Add up the rest of the sides
12.56 + 10 + 17 + 10 + 9 = <u>66.56</u>
18. 12/4 =3, 36/12 =3 the ratio is 3
19. 108/162 =0.667, 72/108= 0.667 the ratio is 0.667 or 2/3
20. 2/3 / 4/3 = 1/2, 1/3 /2/3 = 1/2, the ratio is 1/2

Answer:
(2, -3)
Step-by-step explanation:
Apparently, the equations are supposed to be ...
The solution for x can be found by subtracting the second equation from the first:
(4x +y) -(3x +y) = (5) -(3)
x = 2 . . . . . . . matches the second answer choice
Y can be found from either equation:
y = 5 - 4x . . . . . subtract 4x from the first equation
y = 5 -4(2) = -3
The solution is (x, y) = (2, -3).
