PLEASE HELP ASAP How many hours will it take a culture of bacteria to increase from 20 to 2000 if the growth rate per hour is 50%

200 hours

Step-by-step explanation:

if it increases by 50% of 20 an hour, so it increases 10 and hour. 2000÷10=200

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

5x+10 is the correct one

hope this
