There are 50 sections.

Step-by-step explanation:

Given,

Length of section = 10 meters

Total length of guardrail = 0.5 km

We will convert this length in meters.

1 km = 1000 meters

0.5 km = 0.5*1000 = 500 meters

Now,

No. of sections = \frac{Total\ length\ of\ guardrail}{Length\ of\ one\ section}

No. of sections = \frac{500}{10}

No. of sections = 50

There are 50 sections.

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.
