Viefleur [7K]

Answer:

3/14

Step-by-step explanation:

We need to line up the fractions. 5/7 on top, 1/2 on the bottom. We need to find common denominator so, 7 x 2 (denominators) gives us 14. 14 is now the denominator we will use. Solve for numerator: Starting at bottom fraction. 2 goes into 14 7 times, 7 times original numerator (1) 35. Theres your new numerator. Now, the top fraction: 7 goes into 14 2 times. 2 x original numerator (5) = 10. Now subtract both numerators (10 - 7 = 3) Plug in the denominator and your answer is: 3/14

A certain bacteria colony doubles in size every day for 20 days, at which point it reaches the limit of its habitat and can no l
erma4kov [3.2K]

Answer:

(E). 19

Step-by-step explanation:

Let original population of each colony be P.

We have been given that a certain bacteria colony doubles in size every day, so bacteria colony is growing exponentially. After x days, the population of bacteria would be:

P(2)^x

The population after 19 days will be P(2)^{19} for each colony.

The total population of both the colonies at that point will be P(2)^{19}+P(2)^{19}=2P(2)^{19}=P(2)^{20} which is what the habitat's limit is.

Therefore, it will take 19 days for two bacteria colonies to reach the habitat's limit and option E is the correct choice.
