Answer: There are 6400 bacteria that will be present after 3 hours.
Step-by-step explanation:
Since we have given that
Initial number of bacterial cells = 100
Each cell divides to form two new cells every 30 minutes.
Number of hours = 3 hrs
Number of minutes in 3 hours = 3\times 60 = 180 minutes
Number of 30 minutes in 3 hours = 
So, our equation becomes,
Hence, there are 6400 bacteria that will be present after 3 hours.
Cost subtracted by the amount of money Bobbi has.
$3.75 - $0.75 = $3.00
Still has to pay $3

doesn't have the $3 to pay for the rest of the bandanna
B. $3.00 deficit<span />
Answer:
143 calories
Step-by-step explanation:
We can use a ratio to solve
110 calories x calories
----------------- = ---------------
28.4 grams 36.92 grams
Using cross products
110* 36.92 = 28.4 * x
Divide each side by 28.4
110*36.92 / 28.4 = x
143 calories = x
