The number of ants in his farm after 12 weeks is 218.
Step-by-step explanation:
Step 1:
It is given that there are 15 ants initially and the ant population increases by 25% each week.
This is an exponential rate of increase that can be modeled by the following equation:
Number of ants after n weeks = Initial number of ants * 
Step 2:
Rate of increase = 25% = 25 / 100 = 0.25
Number of weeks = 12
Number of ants after 12 weeks = 15* 
= 218.27 (rounded off to 218)
Step 3:
Answer:
The number of ants in his farm after 12 weeks is 218.
Based on the rate of increase, the number of employees that will be there in 2016 is<u> 21,927 people.</u>
<h3>Number of employees in 2016</h3>
This can be calculated by the formula:
= Employees in 2009 x ( 1 + rate of increase)
Solving gives
= 19,100 x (1 + 14.8%)
= 21,926.8
= 21,927 people
In conclusion, there will be 21,927 people in 2016.

Answer:

Step-by-step explanation:
Use the zero's trick for 10's.
<u> 4 x² = 64</u>
Divide each side by 4 : x² = 16
Take the square root
of each side: x = √16
x = <em>+ 4</em>
and
x = <em>- 4</em> .
-5x + 46 +4z
Combine like terms
-5x + 2x = -3x
-3x + -2x = -5x
14 - (-32) = 46
4z is left alone since it doesn't have a like term.
