A certain colony of bacteria triples in length every 10 minutes. It's length is now 1 millimeter. How long will it be in 40 minutes? Please help answer thx
A certain colony of bacteria triples in length every 10 minutes. It's length is now 1 millimeter. How long will it be in 40 minutes?
A certain colony of bactericia doubles in size every 5 minutes. If the colony began with 2 organisms, how many will there be after 30 minutes?
81 lol
To determine how long the colony of bacteria will be in 40 minutes, we need to identify how many times it triples in length within that time period.
We know that the bacteria triples in length every 10 minutes, so within 40 minutes, it would triple in length four times (40 minutes divided by 10 minutes).
Starting with a length of 1 millimeter, we can calculate the length of the bacteria after each period of tripling.
1st period: 1 millimeter * 3 = 3 millimeters
2nd period: 3 millimeters * 3 = 9 millimeters
3rd period: 9 millimeters * 3 = 27 millimeters
4th period: 27 millimeters * 3 = 81 millimeters
Therefore, after 40 minutes, the colony of bacteria will be 81 millimeters long.
40/10 = 4, so it will triple 4 times.
3^4 = 81
