The population of a certain bacteria doubles in size every 3 hours. If a population begins with one bacterium, how many will the

gladu [14]

There would be 256 bacteria after one day.

There are 24 hours in a day, and the amount of bacteria doubles every 3 hours, so it will double:

24 / 3 = 8 times.

To find the current amount we could use an equation such as:

1 * 2^8 = x

Finally, solve for the number of bacteria:

1 * 2^8 = x

1 * (2 * 2 * 2 * 2 * 2 * 2 * 2 * 2) = x

1 * (4 * 4 * 4 * 4) = x

1 * (16 * 16) = x

1 * 256 = x

x = 256

klasskru [66]

Answer:

200 words are peter can be type in 5 minutes.

Step-by-step explanation:

As given

If peter can type 80 words in 2 minutes .

i.e

80 words = 2 minutes

Now words type in 1 minutes.

$1\ minutes = \frac{80}{2}\ words$

1 minutes = 40 words

Now calculate number of words are type in 5 minutes.

Words are type in 5 minutes = Number of minutes × Number of words are type in 1 minutes.

Number of minutes = 5 minutes

Number of words are type in 1 minutes = 40 words

Words are type in 5 minutes = 5 × 40

= 200 words

Therefore 200 words are peter can be type in 5 minutes.
