Answer: 6
Step-by-step explanation: set the equations equal to each other then solve. plug that number into the equation for AB
Given:
The growth of a sample of bacteria can be modeled by the function

where, b is the number of bacteria and t is time in hours.
To find:
The number of total bacteria after 3 hours.
Solution:
We have,

Here, b(t) number of total bacteria after t hours.
Substitute t=3 in the given function, to find the number of total bacteria after 3 hours.



Therefore, the number of total bacteria after 3 hours is 119.1016.
Answer:
Number of rats : Food weight = 1 : 5
Step-by-step explanation:
Number of rats in the group = 9
Weight of food carried away by them = 45 kg
Ratio of the number of rats and food weight = 
= 
= 
= 
Therefore, Number of rats : Food weight = 1 : 5
To find the distance you would use the distance formula which is:

This equals:
Answer: AB/y = BC/z = AC/x
Step-by-step explanation:
Side AB corresponds to side y, side BC corresponds to side z, and side AC corresponds to side x.
