TO determine the mass of the helium in the balloon, we make use of the density of the gas that is given in the problem and the volume of helium that is present. <span>Density is a property of a
material which describes the mass of a material per unit volume. By multiplying the volume to density, we get the mass of the helium gas in the balloon. We do as follows:
Mass = Density x Volume
Mass = 0.1785 kg / m^3 x 3249 m^3
Mass = 579.9465 kg
Therefore, the mass of helium gas in the hot air balloon would be about 579.9 kg.</span>
Before we answer the question we must first:1. Assess what we have so far.2. Know what we need to find.3. Solve.4. Conclude.
Step 1: What we have so far.*Price of a ream of paper = $4.00
*No. of sheets of paper in a ream = 500pcs.
*A sheet of paper weighs = 0.50oz
Step 2: What we need to find.*The price of 1lb (pound) of paper = ?
Step 3: Solve.*1lb = 16oz
Know how many papers are there in 1lb:
*1lb = 16oz
*1 sheet of paper = 0.50oz
*16oz of paper = 32 pcs of paper.
Because 16 divided by 0.50 is = 32.
*1lb of paper = 32 pcs of paper.
Know how the weight of a ream of paper:
*Ream of paper has 500 papers.
*32 papers = 1lb
500 divided by 32 = 15.625
*Weight of a ream is 15.625lb.
Know how much a pound (lb) of paper is:
*A ream of paper costs $4.00.
*A ream of paper weighs 15.625lb.
4.00 divided by 15.625 = 0.256
*Cost per pound (lb) of paper = $0.256 or $0.26 or 26 cents.
Step 4: Conclusion.After successfully doing the steps above, we can now conclude that the cost per pound of paper is $0.256 or $0.26 or 26 cents.

Answer:
3/4
Step-by-step explanation:
Answer:
5m•5m•5m
Step-by-step explanation:
You are multiply the factor by itself as many times as the exponent says. so if the factor is 5m, you would multiply it by itself by the exponent, which in our case is 3.
