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.

I hope this helps you

at the 30-60-90 triangle has rules

30=>k

60=>k(square root of) 3

90=>2k

so in this triangle 60=> see 9

k(square root of) 3=9

k=9/(square root of) 3

2k=18/(square root of) 3

at the 45-45-90 triangle rules are

45=>2k

45=>2k

90=>[2k/(square root of 3)] (square root of) 2

x=[18/(square root of 3)].(square root of 2)

x=18(square root of 2)/square root of 3

slamgirl [31]

Answer:

483 840 ways

Step-by-step explanation:

Let you and your friend be A and B.

With three people always between you two,, we have

Case 1: AxxxBxxxxx

Case 2: xAxxxBxxxx

Case 3: xxAxxxBxxx

Case 4: xxxAxxxBxx

Case 5: xxxxAxxxBx

Case 6: xxxxxAxxxB

So there is 6 ways of arranging you two through the line and for each of the six cases,

If you two remained in your positions, the rest can be arranged in 8! ways

Also for each case, you two can interchange your positions in 2! ways

Therefore,

The photographer can rearranged the line keep three people between you an your friend in

8! * 2! * 6 = 483 840 ways
