Answer:
2143.6 ft³
Step-by-step explanation:
We use formula number 2 to get the volume. V=4\3πr³
4\3 x 3.14 x 8³ = 2143.573333
Rounded of to the nearest tenth = 2143.6 ft³

Answer:
(c) Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100
Step-by-step explanation:
Try the numbers in the constraints to see if they work.
<u>Build hours</u>:
(4 h/child bike)(10 child bikes) = 40 hours
(6 h/adult bike)(12 adult bikes) = 72 hours
total build hours: 40 +72 = 112, less than 120; constraint is met
<u>Test hours</u>:
(4 h/child bike)(10 child bikes) = 40 hours
(4 h/adult bike)(12 adult bikes) = 48 hours
total test hours: 40 +48 = 88, less than 100; constraint is met
__
Both constraints are met, so the order can be filled.
Answer:
18 Minutes
Step-by-step explanation:
Simon and sophie each do a fraction of the job per minute like this:
-Simon does
per minute (if we multiply this by 30 we have the completed job)
-Sophie does
of the job per minute (again if we multiply this by 45 we have the completed job)
We will add this two to know how much of the job they do together in a minute:

They will do
of the job per minute.
So the total time will be when they do
, we can put this in one equation like this:

where x is the total times we need to do
of the job to complete it. We solve for x:
