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

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
