Answer:

Step-by-step explanation:

Let x equal the first mile marker.  Then x + 1 represents the second mile marker.

Then x + (x + 1) = 561, or

2x + 1 = 561, or

2x = 560, and so x = 280

Then the first mile marker reads 280 and the second mile marker reads 281.

The volume, V, of a rectangular prism is determined using the formula V=lwh, where l is the length, w is the width, and h is the
Olegator [25]

Answer:

Width of the rectangular prism

It is given to us that the volume of the rectangular prism is calculated by the given formula :-

v = lwh

Where,

v = volume

l = length

w = width

h = height

Now,

In the question we are given :-

v = 138.24 cubic inches

h =  9.6 inches

l = 3.2 inches

w = ?

Substitute these values in the volume formula given :-

138.24 = 3.2 * w * 9.6

138.24 = 30.72 * w

w = 138.24/30.72

w = 4.5

⇒ The width of the rectangular prism is 4.5 inches.

Step-by-step explanation:

In the real world, length and width only make sense when they are positive. For that to be the case, the width must be greater than 2. There is nothing in the description that restricts the values to integers.
