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.

Answer:
Step-by-step explanation:
Basically the word problem here is trying to get us to find the line using the two points (113,70) and (173,80).
It also tells us by saying that we're modeling the temperature that we're going to be using the y = mx + b formula. m and b are what we'll mainly be looking for.
Let's start by finding m, the slope. We'll be using the point slope formula:
So m = 1/6.
Now let's use that m and choose one of the points (I chose (113,70) ) to plug in everything but b in the original formula
so now that we know our b and our m, we can plug those into the original equation to get our answer!
Let
x----------> <span>Aidan's age
y----------> M</span><span>aggie's age
we know that
x=4
x=(y/2)-6
so
substitute
4=(y/2)-6----> multiply by 2-----> 8=y-12----> y=8+12-----> y=20
the answer is
</span>M<span>aggie's age is </span><span>20</span>
