Answer:
Option C. 1,024 bacteria
Step-by-step explanation:
We are given that a bacteria culture begins with 4 bacteria which double in size every hour. And we have to find that how many bacteria exist in the culture after 8 hours;
So, Number of bacteria after one hour = 4 * 2 = 8
Number of bacteria after two hours = 8 * 2 = 16
Number of bacteria after three hours = 16 * 2 = 32
Number of bacteria after four hours = 32 * 2 = 64
Number of bacteria after five hours = 64 * 2 = 128
Number of bacteria after six hours = 128 * 2 = 256
Number of bacteria after seven hours = 256 * 2 = 512
Number of bacteria after eight hours = 512 * 2 = 1,024
Therefore, 1,024 bacteria exist in the culture after 8 hours .
He can only pick 7 different groups because 2 times 7 is 14, and there are 15 people in all.
Hope this helps. c:
I believe C. The temperature is -23 degrees.
This is because, a negative (absolute value) becomes positive
Which would lead for |-23| to end up being |23|
Anytime a negative absolute value is placed, it becomes a positive and a positive stays positive.
So the smallest would be C then B later D and at last A
The Volume is V= 84823. say thanks haha
