Answer:
360
Step-by-step explanation:
1. Set up your equation!
= 
2. Cross multiply to solve!
100 times 126 = 12600
35 times x = 36x
3. Continue!
12600=35x
4. Divide the coefficient on both sides to get the variable by itself
=x (the 35 cancels out)
12600 divided by 35 = 360
And there’s your answer! 360
Answer:
The population is 3,000 to the nearest thousand
Step-by-step explanation:
Here, we want to calculate population density
Mathematically;
Population density = population/ area
form the question;
population = 4.2 * 10^5
area = 1.32 * 10^2 square miles
Population density = (4.2 * 10^5)/(1.32 * 10^2)
3.2 * 10^3
which as a whole number will be 3200
To the nearest thousand, this is 3000
