José left Westcliffe on his bicycle riding at an average rate of 8 miles per hour five hours before his father left by automobil
Serga [27]

Answer:

48 miles per hour

Step-by-step explanation:

José left Westcliffe on his bicycle riding at an average rate of 8 miles per hour five hours before his father left by automobile. The father overtook José in exactly one hour. This means Jose was riding

5 hours + 1 hour = 6 hours.

Use formula

D=r\cdot t,

where

D = distance

r = rate

t = time

In Jose's case,

D = unknown

r = 8 miles per hour

t = 6 hours

Hence,

D=8\cdot 6=48\ miles

In Jose's father case,

D = 48 miles

r = unknown

t = 1 hour (father overtook José in exactly one hour)

Hence,

48=r\cdot 1\\ \\r=48\ miles \ per \ hour

Using V = lwh, what is an expression for the volume of the following prism? The dimensions of a prism are shown. The height is S
Lubov Fominskaja [6]
<h2>Explanation:</h2><h2></h2>

We know that the volume of a prism is defined by:

V=lwh \\ \\ \\ Where: \\ \\ l:length \\ \\ w:width \\ \\ h:height \\ \\ \\ l=\frac{d-2}{3d-9} \\ \\ w=\frac{4}{d-4} \\ \\ h=\frac{2d-6}{2d-4}

Substituting values:

V=\left(\frac{d-2}{3d-9}\right)\left(\frac{4}{d-4}\right)\left(\frac{2d-6}{2d-4}\right) \\ \\ \\ Simplifying: \\ \\ V=\frac{d-2}{3d-9}\cdot \frac{4}{d-4}\cdot \frac{d-3}{d-2} \\ \\ V=\frac{\left(d-2\right)\cdot \:4\left(d-3\right)}{\left(3d-9\right)\left(d-4\right)\left(d-2\right)} \\ \\ V=\frac{4\left(d-3\right)}{\left(3d-9\right)\left(d-4\right)} \\ \\ V=\frac{4\left(d-3\right)}{3\left(d-3\right)\left(d-4\right)}

Finally: \\ \\  \boxed{V=\frac{4}{3\left(d-4\right)}}

The length of a rectangle is 12 inches longer than the width. Find the length and width if the perimeter is 184 inches.
solong [7]

Perimeter = 2l + 2w

Divide 184 by 4

184/4 = 46

Subtract by 6

46 - 6 = 40

Add by 6

46 + 6 = 52

The length is 52, and the width is 40.

We can verify by plugging these values into the original equation.

52*2 + 40*2 = 184
