Answer:
2.1
Step-by-step explanation:
The first pipe fills 1/8 of a pool in one hr.
The second pipe fills 1/4 of a pool in one hr.
(1/8+1/4)2= 3/4 done by the first two pipes in 2 hours.
Therefore the last pipe must do 1 1/4 of the filling in 2 hours, which is 5/8 per hour.
5/8x=1
x=8/5
It takes the third pipe 1 hour and 36 minutes to fill it by itself.
Answer:
If the sphere has a radius of 4, you can use the equation: V=4/3(pi)(r)^3
Step-by-step explanation:
V=4/3(pi)(r)^3
V=4/3(pi)(4)^3
D is wrong. D= 0.4 (roughly) A B and C are the same thing = 2.25 9 divided by 4=2.25 In math OF means TIMES (like multipling) and a fraction is dividing :) Hope this helps
Answer:
120 slices
Step-by-step explanation:
We are given that each slice is 1 over 10 of a pizza, so there are 10 slices per pizza (because the denominator represents the total amount of pieces). Since there are 12 pizzas, 12 x 10 = a total of 120 slices.
