Step-by-step explanation:
180*0.55=99 (red)
180*0.6=108 (blue)
108-99=9.
The fan should expect the red team to win 9 fewer games.

Short Answer h = 6.5
Remark
I'm taking it that AB = 2.5 cm and that CD = 4cm
Formula
Area = 1/2(b1 + b2) * h
Givens
Area = 6.5 cm^2
b1 = 2.5 cm
b2 = 4 cm
Substitute
6.5 = 1/2 ( 2.5 + 4) * h
6.5 = 1/2 (6.5) * h Multiply both sides by 2
6.5 * 2 = 6.5 * h Divide both sides by 6.5
6.5 * 2/ 6.5 = 6.5 * h / 6.5
2 = h <<<<<< Answer
Answer:
The length of the semicircle arc is 6π
Step-by-step explanation:
To solve this problem we need to use the circumferenc formula of a circle:
c = circumference
r = radius = 12
π = pi
c = π * d
we replace with the known values
c = π * 12
c = 12π
The length of the circumference is 12π
N
ow we divide the circumference by 2 and we will obtain the length of the arc of the semicircle
12π / 2 = 6π
The length of the semicircle arc is 6π
