It takes 21 minutes for a certain population of bacteria to double. If there are approximately 8,014,000 bacteria in this population at 10 a. M., what is the best estimate, in millions, of the number of bacteria at 10:42 a. M. On the same day?

32 million

Step-by-step explanation:

Given that:

Time it takes population to double = 21 minutes

Number of bacteria at 10a.m = 8,014,000

Best estimate of bacteria at 10:42

Difference :

10:42 - 10:00 = 42 minutes

42/ 21 = 2 times

Hence it doubles 2 times within the time range :

At 10:21 minutes :

8,014,000 * 2 = 16,028,000

At 10:42 minutes :

16,028,000 * 2 = 32,056,000

Best estimate is 32 million

452,489 to the nearest thousand is 452,000

answer: 12

step-by-step explanation:

because yes
