The math club could rent the room for up to 8 hours. I have also attached a picture of the work in case you need it.
Answer:
(6,0)
Step-by-step explanation:
The given system has equations:


Multiply the top equation by 2 to get:


Subtract the top equation form the bottom equation to get:



Put y=0 into 


Therefore the solution is (6,0)
Answer:
<em>The mass of the steel ball is 4,235.9 gr</em>
Step-by-step explanation:
<u>Density</u>
The density ρ of a substance is a measure of its mass per unit volume:

If the density and the volume are given, the mass can be calculated by solving the above formula for m:

We know the density of pure steel ρ=8.09 gr/cm3 and the diameter of a solid steel ball d=10 cm.
We need to calculate the volume of the sphere:
The volume of a sphere of radius r is given by:

The radius is half the diameter: r= 10/2 = 5 cm. Thus:

Calculating:

The mass is:

m=4,235.9 gr
The mass of the steel ball is 4,235.9 gr
