Answer:

Density = mass/volume

Step-by-step explanation:

The mass per unit volume of a given substance is called its density. It can be represented by d or ρ. Mathematically, it is given by :

density=mass/volume

The SI unit of mass is kg and the SI unit of volume is m³. So, the SI unit of density is kg/m³.

So, the statement that defines density is "A measure of how much mass a given volume of a substance will have". Hence, the correct option is (c).

Answer:

Below

Step-by-step explanation:

Sale price of each tire : $92.99 - $20 = 72.99. The cost of x tires is 72.99x

If the sales tax is 4% there is an additional (72.99x)(1.04)

Here is the equation

= (72.99)(1.04) t

If Patrick bought 8 tires.....

= (72.99)(1.04)(8)

= $607.2768

Hope this helps!

Solve for . Simplify your answer as much as possible. please help

Sonja [21]

Answer:

$x=-6$

Step-by-step explanation:

So we have the equation:

$-34=7(x+8)+8x$

First, distribute the 7 into the (x+8) and simplify:

$-34=7(x)+7(8)+8x\\-34=7x+56+8x$

Combine the like terms 7x and 8x by adding them together:

$-34=56+15x$

Subtract 56 from both sides to isolate the x:

$-34-56=15x+56-56\\15x=-90$

Divide both sides by 15 to get x:

$x=-90/15=-6$

What is an equation of the line that is perpendicular to -x+2y=4 and passes through the point (-2, 1)?

KATRIN_1 [288]

First: Slope of -x+2y=42y=x+4y=x/2+2So, m=1/2.
Second: Slope of the perpendicular line: mp=-2.
Third: Find the line with slope -2 and passes through the point (−2, 1)y-y1=m(x-x1)y-1=-2(x+2)y=-2x-4+1y=-2x-3
