The formula for density of an object is Density= $\frac{mass}{volume}$ First you plug in the information you already know. 163.5= $\frac{mass}{0.492}$ Now you have to solve for the mass so you multiply 0.492 by 163.5 $0.492*163.5=80.442$ Lastly, you simplify and you will get 80.44. Hope this helped :)

Answer: y = 0.45x + 21

Step-by-step explanation:

let x represent the number of minutes used in a month.

Let y represent the monthly cost for x minutes.

If we plot y on the vertical axis and x on the horizontal axis, a straight line would be formed. The slope of the straight line would be

Slope, m = (304.5 - 183)/(630 - 360)

m = 121.5/270 = 0.45

The equation of the straight line can be represented in the slope-intercept form, y = mx + c

Where

c = y intercept

m = slope

To determine the y intercept, we would substitute x = 360, y = 183 and m = 0.45 into y = mx + c. It becomes

183 = 0.45 × 360 + c

183 = 162 + c

c = 183 - 162

c = 21

The equation for the monthly cost is

y = 0.45x + 21

What is a simlified form of x+3 over x^2-x-12 multiplied by x-4 over x^2-8x+16?

Vesnalui [34]

Answer:

$\large\boxed{\dfrac{x+3}{x^2-x-12}\cdot\dfrac{x-4}{x^2-8x+16}=\dfrac{1}{x^2-8x+16}}$

Step-by-step explanation:

$\dfrac{x+3}{x^2-x-12}\cdot\dfrac{x-4}{x^2-8x+16}=\dfrac{x+3}{x^2+3x-4x-12}\cdot\dfrac{x-4}{x^2-8x+16}\\\\=\dfrac{x+3}{x(x+3)-4(x+3)}\cdot\dfrac{x-4}{x^2-8x+16}=\dfrac{x+3}{(x+3)(x-4)}\cdot\dfrac{x-4}{x^2-8x+16}\\\\\text{cancel}\ (x+3)\ \text{and}\ (x-4)\\\\=\dfrac{1}{x^2-8x+16}$
