-- 9 people paint 5 walls in 60 minutes
-- 9 people paint (5 / 5) = 1 wall in (60 / 5) = 12 minutes
-- (9 / 9) = 1 person paints 1 wall in (9 x 12) = 108 minutes
-- 1 person paints (1 x 6) = 6 walls in (108 x 6) = 648 minutes
-- (1 x 4) = 4 people paint 6 walls in (648 / 4) = 162 minutes .
Answer:
Yvonne's bill = $16.5
Step-by-step explanation:
let
Total of the bill = a
If they split the bill equally = a/3
Yvonne's bill = 3 + a/3
Victoria's bill = $12
Wanda's bill = $12
a = 3 + a/3 + 12 + 12
collect like terms
a - a/3 = 27
(3a - a )/3 = 27
2a/3 = 27
cross multiply
2a = 81
divide both sides by 2
a = 81/2
a = 40.5
Yvonne's bill = 3 + a/3
Yvonne's bill = 3 + 40.5/3
Yvonne's bill = 3 + 13.5
Yvonne's bill = $16.5
The formula for an arc length is, <span>S = r<span>θ, where r is radius and <span><span>θ is theta. Theta must be in radians (which it is because you stated theta = 4 pi / 7). Multiply 5 and 4 pi / 7, the arc length will be 20 pi / 7. It will be 8.97 when you compute this into a calculator (rounded to the nearest hundredth). Found this helpful?
