Aweather balloon holds 2,000 cubic meters of helium. the density of helium is 0.1765 kilograms per cubic meter. how many kilograms of helium does the balloon contain? only enter a numerical value in the answer blank.

353 kg.

Step-by-step explanation:

We have been given that a weather balloon  balloon holds 2,000 cubic meters of helium. The density of helium is 0.1765 kilograms per cubic meter.

We will use density formula to find the mass of helium.

Upon substituting our given values in above formula we will get,

Therefore, the ball contains 353 kilograms of helium.

step-by-step explanation:

4^(x+2)=12

4^(x+2)=12

take the log base 4 on each side

log 4 (4^(x+2) = log 4(12)

we know log b(a^y) = y log b (a)

(x+2) log 4(4) = log 4 (12)

x+2 = log 4 (12)

we know   logb c = loga c/loga b

we want to convert to base 10   so a = 10

by default, we do not write the 10   c = 4   and b = 10

log4 10 = log 12/log 4

log4 10 = log 12/ log 4

x+2 = log 12/ log 4

subtract 2 from each side

x +2 -2 = log 12/ log 4 -2

x = 1.79248125 -2

x =-.20752
