Answer:
A circle with circumference 18 had an arc with 120 central angle.
=> Radius of that circle: R = 18/(2 x pi) = 2.86
=> Length of that arc: L = R x 120 x pi/180 = 2.86 x (2/3) x pi = 5.99
Hope this helps!

Answer:
6
Step-by-step explanation:
Angle: arc length
360 : 18
120 : X
X/120 = 18/360
X = 120 × 18/360
X = 6

1/2 is the probability the coin would land heads up both times.
That can be factored to:
(x+6)(x+4)
24x^2 + 10x = 2x(12x + 5)
