Within a radius of 4.9 miles of a cell phone tower, 1483 people per square mile enjoy quality phone signals. what is the population of cell phones users within the towers converage area

The population around the tower is 111,862 people.

Step-by-step explanation:

In order to solve this problem we first need to calculate the area surrounded by the tower, since it's a circle we can apply the following formula:

tower area = pi*r²

tower area = pi*(4.9)² = 75.4296 miles²

For every mile² there are 1483 people, therefore:

population = area*density

population = 75.4296*1483 = 111,862

The population around the tower is 111,862 people.

step-by-step explanation:

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.
