Answer:
The region with the highest population density is Binky Lee
The region with the lowest population density is Cheslen
Step-by-step explanation:
we know that
The <u><em>population density</em></u> is the number of people per unit of area
so
Find out the population density for each region
<em>Bear Creek</em>
<em>Binky Lee</em>
<em>Cheslen</em>
<em>Crow's Nest</em>
so
Cheslen < Crow's Nest < Bear Creek < Binky Lee
therefore
The region with the highest population density is Binky Lee
The region with the lowest population density is Cheslen
Answer: 
, 
, 
and 
Step-by-step explanation:
Here, x represents the number of hours Zoe spent running on her wheel and y represents the number of hours spent scratching her cage.
Julie was awoke for at least an hour running on her exercise wheel and scratching the of her cage.
⇒
She ran on her wheel at least twice as long as she scratched at the corners of her cage.
⇒
Also, She spent more than 1/4 hour running on her wheel.
⇒
And, we know that number of hours can not be negative.
⇒
Therefore, the complete system of inequality which shows the given situation is,
, and ,
Note: the feasible region ( covered by the given system) is shown in the below graph.
To make it easier convert the times all into minutes.
2 hours 20 minutes = 120 minutes + 20 minute = 140 minutes
4 hours 10 minutes = 240 minutes + 10 minutes = 250 minutes
Then subtract:
250 minutes - 140 minutes = 110 minutes
Convert back to hours/minutes:
110 minute = 1 hour and 50 minutes
