Question

I REALLY NEED HELP PLEASE HELP!

Mahesh wants to inflate twenty-five foil balloons with helium. If each balloon requires zero point 4 5 cubic feet of helium, how much total helium will he use?

Answer 1

total amount of helium used = 0.25*25=6.25 cubic feet

Answer 2

@twilaswift clear?

Answer 3

one balloon requires 0.45 cubic feet of helium, so two balloons would need twice this amount of gas ( 2 x 0.45 cubic feet), hence by the same reasoning 25 balloons would need 25 x 0.45 cubic feet of helium.

Answer 4

zero point 1 1 2 5 cubic feet

1 point 1 2 5 cubic feet

eleven point 2 5 cubic feet

one hundred twelve point 5 cubic feet

Answer 5

i mean 0.45*25=11.25 cubic feet
