What is the relationship between mass, density and volume? Provide and example that involves calculating population density.
Ymorist [56]

Answer:

Density is directly related to the mass and the volume. In fact, it tells us of the exact relationship between the two. To find an object's density, we take its mass and divide it by its volume. If the mass has a large volume, but a small mass it would be said to have a low density.

Trey had a cylindrical can with a radius of 4 inches and a height of 12 inches that was completely full of beet juice. He poured
Arisa [49]

Answer:

8\ glasses\ of\ juice

Step-by-step explanation:

step 1

Find the volume of the cylindrical can

The volume of the cylinder is equal to

V=\pi r^{2}h

we have

r=4\ in\\ h=12\ in

substitute the values

V=\pi (4)^{2}(12)=192\pi\ in^{3}

step 2

Find the volume of the cylindrical glasses

The volume of the cylinder is equal to

V=\pi r^{2}h

we have

r=2\ in\\ h=8\ in

substitute the values

V=\pi (2)^{2}(8)=32\pi\ in^{3}

Find the volume of 3/4 of the glass

32\pi (\frac{3}{4})=24\pi\ in^{3}

step 3

Divide the total volume of cylindrical can by the 3/4 volume of the glass

192\pi\ in^{3}/24\pi\ in^{3}=8\ glasses\ of\ juice

is 3x+4y=12 linear or nonlinear......is y=1/2x+6 linear or nonlinear......is y=4x to the power of 2 linear or nonlinear......is
Ilya [14]

3x+4y=12 is Linear.

y-1/2x+6 is Linear.

y=4x^2 is nonlinear.

y+2=|4| is linear.

y+6=4x is linear.

In order to tell whether an equation is linear or not, you have to first see if there is any variable^2 or more than ^1. If that is the case, it isn't linear. For example the equation x^2=4 or y^5=100 isn't linear. It also isn't linear if the equation is divided by X or Y.For example the equation 1/x=1 isn't linear or 1/y^2=5 isn't linear.

A question is also linear if you can write it in the form y=mx+b , 'm' meaning the slope of the equation and 'b' meaning the y-intercept of the equation.
