A hot air balloon holds 2,200 cubic meters of helium. The density of helium is 0.1785 kilograms per cubic meter. How many kilograms of helium does the balloon contain, rounded to the nearest tenth of a kilogram? (5 points) 2,199.8 kg 11,195.9 kg 392.7 kg 2,200.2 kg

ok see.. here:

density is 0.1785 kilograms per cubic meter

volume is 2,200 cubic meters

and we need mass...

so just put all these in the formula and solve.

Step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.

a28=58

step-by-step explanation:

a1=a1+(n-1)d

a28= 4+ (28-1)2

a28=4+(27)(2)

a28=4+54

a28=58
