First, multiply the number of feet it takes for one balloon by the number of balloons filled daily.
0.5 * 80 = 40
So, 40 cubic feet is 20% of one tank. Now, unless you remember how to find what 40 is 20% of, simply play around with some numbers on your calculator until you find that 200 * 0.20 = 40. I would love to explain how to find that part with an actual formula, but I don't remember how. :/ Hope this helped.
Answer:
41
Step-by-step explanation:
Answer:
ok
Step-by-step explanation:
Prove:
Using mathemetical induction:
P(n) = 
for n=1
P(n) =
= 6
It is divisible by 2 and 3
Now, for n=k, 
P(k) = 
Assuming P(k) is divisible by 2 and 3:
Now, for n=k+1:
P(k+1) = 
P(k+1) = 
P(k+1) = 
Since, we assumed that P(k) is divisible by 2 and 3, therefore, P(k+1) is also
divisible by 2 and 3.
Hence, by mathematical induction, P(n) =
is divisible by 2 and 3 for all positive integer n.
