Answer:

2500 people PER square mile

Step-by-step explanation:

THe population density is the population per unit area.

Here,

Given:

Population = 400,000

Total Area = 160 sq. miles

To get population density, we would need the population PER UNIT AREA, per miles.

We can get that by dividing the total population by total area:

400,000/160 = <u>2500 people PER square mile</u>

This is the population density.

sladkih [1.3K]

Answer:

  1 in = 500 km

Step-by-step explanation:

It is nice to choose a scale that leaves a little border, so one could probably make it ...

  10 in = 5000 km

  1 in = 500 km

__

If you'd rather have a "nice" ratio, you could use ...

  2.5 cm = 500 km   ⇒   1 : 20,000,000

_____

<em>Additional comment</em>

An inch is 2.54 cm, so using 2.5 cm for the same distance means the map is slightly smaller. It would end up about 9.8 inches wide, leaving a border of almost 0.6 inches on either side.

You might want a scale that makes it easy to draw using the tools you have. If your distances are in km, and you have an inch ruler, then the first choice might be better. If you have a centimeter ruler, then the second scale might work better for you.

The unitless scale is found by doing the division:

  \dfrac{2.5\times10^{-2}\text{ m}}{5.00\times10^5\text{ m}}=\dfrac{1}{2\times10^7}=\dfrac{1}{20,000,000}

Mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.

  • A linear pair is made up of two angles, and the sum of their measures is 180°.

<h3>What is the formula for linear pairs?</h3>
  • A two-variable linear equation of the form axe + by + c, with a, b, and c all being real numbers and not equal to zero.
  • The Transitive Property states that if all real numbers x, y, and z are equal, then x=z.
  • Substituting characteristics. If x=y, then x can be swapped to y in any equation or formula.
  • Mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.
  • A linear pair is made up of two angles, and the sum of their measures is 180°.
  • Line pairs can be congruent.
  • Adjacent angles are joined by a vertex.
  • Angles that are similar cross across.
  • A linear pairing is unnecessary.

Therefore, mathematically speaking, the linear pair postulate and linear pair theorem both express the same thing.

  • A linear pair is made up of two angles, and the sum of their measures is 180°.
