Answer:

yes, they are proportional

Step-by-step explanation:

A proportion is a relation that can be modeled by a straight line through the origin. The equation will have the form ...

y = kx

where x is the independent variable, y is the dependent variable, and k is a constant of proportionality.

If you start with the equation relating distance, rate, and time:

d = rt

and you fix the time at 50 seconds, then the equation becomes ...

d = 50t

This is the equation of a proportion with a constant of proportionality of 50. It tells you the distance run is proportional to the rate you run. When this equation is graphed, it is a straight line through the origin.

The population density of the world is calculated by finding the ratio of the total number of people in the world to the area of

Romashka [77]

Answer:

Step-by-step explanation:

A = Surface area of the Earth = $1.5\times 10^8\ \text{km}^2$

Total number of people on Earth = 7.594 billion as of 2018 = $7.594\times 10^9$

We need to find the number of people living in each square km of land area.

So, we need to divide the number of people by the land area of the Earth.

$1.5\times 10^8\ \text{km}^2=7.594\times 10^9\ \text{people}$

$\Rightarrow 1\ \text{km}^2=\dfrac{7.594\times 10^9}{1.5\times 10^8}$

$\Rightarrow 1\ \text{km}^2=50.63\approx 51\ \text{people}$

So, 51 people will inhabit each square km of land area.
