physics
15/f - I really need help with a physics question my teacher gave me. Weve already gone over it, but i wasnt at school, so now he wont tell me how to work it out and what the answer is even though i need to know bc i was absent. Here it is:
"The information on a Party Balloon kit containing a tank of Helium states how many of each size balloon you can expect to fill from the tank. The label states that the tank will fill THIRTY 9-inch balloons. You plan to use 11-inch balloons instead of 9" ones, so how many can you expect to be able to fill?"
can you please solve this and tell me how to work it? I'd really REALLY appreciate it.

Maybe give some free advice about: School?
ok, so the tank will fit thirty 9 inch ballons, so if the ballons were 1 inch.. you would have to mutliply that 30 by 9 correct?
so , 30 x's 9 =270
so, in that tank there would fit 270 1 inch ballons.
since there's 11 inch ballons
you devide that 270 by 11.
which is 6.36363636..
but, since you can't put a 1/3 of a ballon, its 6
so 6 ballons.
want to see how its correct?
go back to the basic problem.
9 inch ballons, you'd do 270 devided by 9
which = 30
(: correct!
righ this out, it'll make more sense.
