Question

The number of bacteria in the colony doubles every hour. If the colony begins with 5 bacteria, how many bacteria will be present after 5hours?

Answer 1

To find the number of bacteria present after 5 hours, multiply the starting number of bacteria by 2, five times. After 5 hours, there will be 160 bacteria present in the colony.

Step-by-step explanation:

To find the number of bacteria present after 5 hours, we need to multiply the starting number of bacteria by 2, five times. Let's calculate:

1. Starting with 5 bacteria, after 1 hour there will be 5 x 2 = 10 bacteria.
2. After 2 hours, there will be 10 x 2 = 20 bacteria.
3. After 3 hours, there will be 20 x 2 = 40 bacteria.
4. After 4 hours, there will be 40 x 2 = 80 bacteria.
5. Finally, after 5 hours, there will be 80 x 2 = 160 bacteria.

Therefore, after 5 hours, there will be 160 bacteria present in the colony.
