Answer:
The population growth is 6.26 per square mile per year
Step-by-step explanation:
We are given
he US Census found at the population per square mile in the state rose from 128.7 to 191.3 during the last 10 years
So,
Initial population =128.7
Final Population =191.3
Total time =10 years

now, we can plug values
So,
The population growth is 6.26 per square mile per year
Answer:
20%
Step-by-step explanation:
We can start by finding out how much the price of the television was reduced by.
250 - 200 = 50
Now, we need to know what percent of 250 is 50? Let x represent the percent of 250 that is 50. Using this, we can set up an equation:
<u />
Notice that a percentage can also be written as that number over 100.
Reduce the fraction (250 and 100 have a common factor of 10)
Reduce the fraction again (25 and 10 have a common factor of 5)
Multiply both sides by two
Divide both sides by 5
Therefore the price of the television was reduced by 20%.
