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.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
