In a certain year. Cairo has a population of 10,400,000. The land area of Cairo is 520 km square kilometers If the population density (number of people per square kilometer) of Cairo during this year wask people km, what is the value of k?

20,000 per sq. km.

Step-by-step explanation:

In this question, the variable k represents the total number of people in a single square km. Since we are provided both the total number of the population and the total square kilometers of the land, we can calculate the value of k by dividing the population size by the total land. Therefore, the calculation would be the following...

= k

20,000 per sq. km. = k

Finally, we can see that the value of k is 20,000 per sq. km.
