We will evaluate each case separately:
with a roller:
P1 = (40/8) * 10 + (1/2) * 10 = 55 $
spray gun:
P2 = (40/20) * (5 + 10) + (1) * (10) = 40 $
Then, the saving is:
P1-P2 = 55-40 = 15 $
answer:
you save by using the spray gun on a paint job that involves painting 40 m2 15 $
Answer:
.00126 lb of icing
Step-by-step explanation:
Just divide 1.26 lb by 1000 since there were 1000 cakes and she used 1.26 total, and we want to find how much for just one cake.
MEAN (add up all the numbers then divide by how many numbers there are. Aka the average)
10 + 20 + 15 + 15 + 60
120 ÷ 5 = 24
MEDIAN (the number in the middle)
15
MODE (most repeated number)
Also 15
Answer:
3964 in³
Step-by-step explanation:
volume of sphere: V = 4/3 πr³
v₁ = 4/3 x 3.14 x 7³ = 1436
volume of prism: v = Bh B = 15 x 18 = 270 h = 20
v₂ = 270 x 20 = 5400
v₂ - v₁ = 5400 - 1436 = 3964 in³
