Answer:
Total <u>480 liters</u> of ice cream is in the cartons.
Step-by-step explanation:
Given:
An ice cream shop is testing some new flavors of ice cream. They invent 25 new flavors for customers to try, and throw out the 13 least popular flavors. The shop makes 80 cartons of each of the remaining flavors. It takes 2 cartons to get one liter of ice cream.
Now, to find the total ice cream in the cartons.
The ice cream shop invent new flavors = 25.
And ice cream shop throw out least popular flavors = 13.
So, to get the remaining ice cream we subtract quantity of flavors ice cream shop throw out from the quantity of flavors ice cream shop invent:
Thus, the remaining flavors = 12.
<em>According to question, the shop makes 80 cartons of each of the remaining flavors. And it takes 2 cartons to get one liter of ice cream.</em>
So, we get the unit rate of liter per carton:
If, 2 cartons contain 1 liter.
Then, 1 carton contain =
<u><em>Total quantity of ice cream per carton = 0.5 liter</em></u>
<u><em>Total number of cartons = 80.</em></u>
<u><em>Total flavors of ice cream = 12.</em></u>
Now, to get the total ice cream in the cartons we multiply total quantity of ice cream per carton by total number of cartons by total flavors of ice cream:
Therefore, total 480 liters of ice cream is in the cartons.
Answer: There will 486 bacteria in 31 hours.
Step-by-step explanation:
The population decay in bacteria is exponential.
Exponential function : , where A = initial population, b multiplication decay factor, t= time:
As per given:
Initial population:
After 36 hours, population =
Divide both sides by 120,000 we get
Taking natural log on both sides , we get
At x= 31,
Hence, there will 486 bacteria in 31 hours.
