Step-by-step explanation:
Population density is expressed as the ratio of the total number of people, N living in or occupying an area or space to the total area or space. Therefore
Population density = number of people/area
A) The town of Manchester (population 50,000) has the shape of a rectangle that is 5 miles wide and 7 miles long. The area would be
5 × 7 = 35 square miles
Population density = 50000/35
= 1429 people/square mile
B) The business area has radius of 1 mile. Its area would be
πr² = 3.14 × 1² = 3.14 square miles.
The area where people reside outside the business area is
35 - 3.14 = 31.86 square miles
Population density = 50000/31.86
= 1569 people per square mile
The diameter is 6 feet, so the radius is 3 feet.
The formula to solve for the areas of a circle is
A = πr^2
So, A = (3.14)(3^2)
A = 28.26
Since the table is cut in half, divide the total answer by 2
A = 14.13
Multiply $72 into 5% and that should give you an answer
Ur independent variable is ur x values....ur dependent variable is ur y values..so if hrs are on the x axis, then ur independent values are ur hrs (or time)....and ur dependent values are ur distance.
(0,0),(2,50)
slope = (50 - 0) / (2 - 0) = 50/2 = 25
y = mx + b
slope(m) = 25
and since u have point (0,0), ur y int (b) = 0
so ur equation is y = 25x + 0 which is written as y = 25x...which is basically saying that he travels 25 miles per hr
how far will he travel in 24 hrs.....so sub in 24 for x
y = 25(24)
y = 600 miles
in summary : The dependent variable is distance, the equation is y = 25x and the dragonfly will fly 600 miles.
