About 70,000 people live in a 6-mile radius of a city's town hall. Find the population density in people per square mile. Round

nika2105 [10]

Answer:

The population density is 618.93 per square mile.

Step-by-step explanation:

It is given that,

No. of people, N = 70,000

The radius of a city's town hall, r = 6 miles

We need to find the population density. It can be calculated by the formula i.e. number of people divided by area of land such that,

$P=\dfrac{N}{A}\\\\P=\dfrac{N}{\pi r^2}\\\\P=\dfrac{70000}{\pi (6)^2}\\\\P=618.93\ \text{per square mile}$

So, the population density is 618.93 per square mile.

Y=-x+1 y=2/3x-4 please answer this!!!!

yawa3891 [41]

Answer:

(x, y) = (-15, -14)

Step-by-step explanation:

y = x+1

y = 2/3x - 4

Next, we will substitute the value of y (first equation) into the second equation.

x+1 = 2/3x - 4

1/3x + 1 = -4

1/3x = -5

x = -15

So, y = -14
