Answer:
7 females, 24 males
Step-by-step explanation:
I solved it by using this equation:
2x + 17 = 31
then, i subtracted 17 on both sides:
2x=14
then divide by 2 on both sides:
x=7
then I added 7 to 17 to find the number of males:
7+17= 24
2:3
?:36
36/3=13
2x13=26
26:36
26+3=29
29:36

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.
t=45min
d=4km
45min/60min = 0.75 hours
v=d/t
v=4km/0.75hours
v=5.33km/hour. So the answer is B. 45 minutes.
