Let's assume you start with one bacterium:
Step by step this gives you:
½ hour: 2
1 hour: 4
1½ hours: 8
2 hours: 16
2½ hours: 32
3 hours: 64
3½ hours: 128
4 hours: 256
You will notice that the number doubles each hour. So you can just apply the formula: bacteria = 2t, where t is the number of time periods. In this case we have 8 half-hours, so that's 28, or 256.
A bacteria splits in half after 20 minutes, so that after 20 minutes there are 2 bacteria, and after 40 minutes there are 4 bacteria. How many bacteria will there be after 2 hours?
You will have 16,777,216 bacteria after 24 hours if it reproduces once.
there are more than 10,000 bacterium in 5 hours
2,097,152
After six hours, and assuming they all survive dividing, you would have 232144
It depends on the species of bacteria as some divide more rapidly than others.
It would take 5 hours to get over 1000.
There were 20000*(1+340/100) = 20000*4.4 = 88000
I would say 2,361,183,241,434,822,606,848 based on: every 20 minutes for 24 hours = 72 times "doubling" after the initial doubling of 1 to 2, that leaves 71 more times, so the equation should be 271 = 2,361,183,241,434,822,606,848 ~= 2.36118324 × 1021
A bacteria splits in half after 20 minutes, so that after 20 minutes there are 2 bacteria, and after 40 minutes there are 4 bacteria. How many bacteria will there be after 2 hours?
486
You will have 16,777,216 bacteria after 24 hours if it reproduces once.
If B(t) represents the number of bacteria after t hours, then B(t) = 43.9157*(1.7533)t for t >= 0.
24 hours
no.
there are more than 10,000 bacterium in 5 hours
Bacteria can reproduce extremely quickly if in the right environment. Under favorable conditions, a single bacteria can reproduce 108 bacteria in twelve hours.
