ROUND the answer to the Nearest WHOLE NUMBER. ( or it won't be right )

Answer 1

6435 is the answer......................

Answer 2

Answer: The required number of bacteria after 16 hours is 5400.

Step-by-step explanation: Given that a culture started with 3,000 bacteria and after 2 hours it grew to 3,300 bacteria.

We are to predict the number of bacteria that will be present after 16 hours.

We have

in 2 hours, the number of bacteria increased from 3000 to 3300.

So, in 2 hours, numbers of bacteria that grew = 3300 - 3000 = 300.

That is, in 1 hour, numbers of bacteria grew will be

`n_1=(300)/(2)=150.`

Therefore, the number of bacteria that will grew in 16 hours is given by

`150* 16=2400.`

Hence, the total number of bacteria that will preset after 16 hours will be

`3000+2400=5400.`

Thus, the required number of bacteria after 16 hours is 5400.
