Answer:
1000 *
Bacteria after 18 hours,
Step-by-step explanation:
The condition given in the problem is that the number of bacterial triple after every 2 hours.
So, after 2 hours, total bacteria= 1000 * 3
So, after 4 hours, total bacteria= 1000 * 3 * 3
Therefore, the general format for the number of bacteria is 1000 *
, where n is the number of times the bacteria has tripled.
In 18 hours, there are
ties that the bacteria has tripled.
Therefore, the no. of bacteria after 9 hours= 1000 * 
1.) Simply to 1/5 and 1/10
2.) put in decimal form 1/5= .2 and 1/10 = .1
3.) Add = .3
