Answer:
Time for bacteria count reaching 8019: t = 2.543 hours
Step-by-step explanation:
To find the composite function N(T(t)), we just need to use the value of T(t) for each T in the function N(T). So we have that:
Now, to find the time when the bacteria count reaches 8019, we just need to use N(T(t)) = 8019 and then find the value of t:
Solving this quadratic equation, we have that t = 2.543 hours, so that is the time needed to the bacteria count reaching 8019.
Answer: each of the students took 1/4 of an eraser home.
Step-by-step explanation:
On the last period our teacher had 1/2 of an eraser left. She gave it equally to 2 students. This means that the amount of eraser that each student takes home would be
(1/2)/2 = 1/2 × 1/2 = 1/4 of an eraser. Converting to decimal, it becomes 0.25 of an eraser.

Answer:
Step-by-step explanation:
Let the larger number = 6
Let the smaller number = 4
Ratio
The greater number = 6
The smaller number = 4
The ratio is 6/4 = 3/2
Isn't that a bit amazing? If you multiply 6 * 4 you get 24. You would think that that is the lowest common multiple. It isn't.
6: 3 * 2
4: 2 * 2
The lowest common multiple is one with 1 three and 2 twos.
