To solve this problem, we need to know that
arc length = r θ where θ is the central angle in radians.
We're given
r = 6 (units)
length of minor arc AB = 4pi
so we need to calculate the central angle, θ
Rearrange equation at the beginning,
θ = (arc length) / r = 4pi / 6 = 2pi /3
Answer: the central angle is 2pi/3 radians, or (2pi/3)*(180/pi) degrees = 120 degrees
Answer:
4. 54- 8.5x>20
Step-by-step explanation:
Catherine only has $54, so she cannot spend more than that.
The canvas will cost at least $20, but we don't know how much exactly.
The tubes cost $8.50 each.
So, she starts with a total budget of $54, out of which she will buy paints (8.5x) and she wants to have at least $20 left for canvas.
So, we transpose those facts into the inequity:
54 - 8.5x > 20
I wanna say (C) would be your best bet correct me if I’m wrong
80 because wht the ratio is implying is that for every boy there is the same amount of girls
Total servings to cups is 7:4
means total servings is 7 and total cups is 4
total=cups+cones
therefor
cones=total-cups
we want servings to cones
we know that cups=4 units and total =7
we apply
cones=total-cups
cones=7-4
cones=3
cones=3 units
therefor, serrvings to cones is 7:3
answer is C
