Question

If the number of bacteria in a colony doubles every 210 minutes and the population is currently 8,000 bacteria, what will the population be in 630 minutes?

Answer 1

Answer:

in 630 minutes, the population of the bacteria  will  64,000

Step-by-step explanation:

current population of the bacteria = 8,000

and this population doubles every 210 minutes

0 (minute) ------------------------ 8,000 bacteria

210 + 0 (210 minutes) -------------------- 2 x 8,000 = 16,000 bacteria

210 + 210 ( 420 minutes) -------------------- 2 x 16,000 = 32,000 bacteria

420 + 210 (630 minutes) -------------------- 2 x 32,000 = 64,000 bacteria

Therefore, in 630 minutes, the population of the bacteria  will  64,000
