So, after 30 mins we have:

100*2

After 1 hour: 100*2*2, etc


the number of 2s will be the number of time they will divide: 3 hrs divided by 0.5 hour: this is six times.

So the final number of cells will be:

100* 2^{6} =100 *2*2*2*2*2*2= 100 *8*8=100 *64=6400


So after 3 hrs there will be 6400 cells there!

Answer:

Divide the number of contestants by 4 and when there is 120 contestants there is 30 winners

Step-by-step explanation:

Looking back at past sequences we can see that when we had 8 contestants we had 2 winners 8/4=2 and we also saw 16/4=4 so that was the formula now we just had to do it on 120 contestants and now we get 30 winners....Hope this helps! :)
