Total miles traveled in p hours = p*q miles and 
Total miles traveled in r hours = r*s miles
so, average rate of speed = total miles traveled / number of hours
                                     =[{(p*q)+(r*s)} / (p+r)] miles per hour

The rectangular prism is made of 8 cubes and has and edge length of 1/2 in, what is the volume
sashaice [31]
Hello!

To find the volume of the prism you first have to find the volume of a cube

To do this you use the equation

V =  a^{3}

V is volume
a is side length

Put in the values you know

V =  \frac{1}{2}^{3}

Solve

V = 0.125

Now to find the volume of the prism you multiply the volume of one cube by the amount of cubes in the prism

0.125 * 8 = 1

The answer is 1 cubic inch

Hope this helps!

First we define variables:
 x: Money Peter receives
 y: Money Paul receives
 z: Money Jane receives
 We write the system of equations:
 x / y = 13/12
 x / z = 13/7
 x = z + 78
 Solving the system we have:
 x = $ 169
 y = 156 $
 z = 91 $

2-4/2-(-3)

-2/5
