Answer: 27people
Step-by-step explanation:
The turkey weighs 9 pounds.
Each member of the family will eat 1/3 of a pound.
If this is the case, the number of people that it would take to finish the turkey will be:
= Weight of turkey / Pounds eaten per person
= 9 ÷ 1/3
= 9 * 3/1
= 27people
This is a typical radioactive decay problem which uses the general form:
A = A0e^(-kt)
So, in the given equation, A0 = 192 and k = 0.015. We are to find the amount of substance left after t = 55 years. That would be represented by A. The solution is as follows:
A = 192e^(-0.015*55)
<em>A = 84 mg</em>
Answer: 4 hours 30 minutes
Step-by-step explanation:
36/8 = 4.5 hours
hours = 4, minutes = 0.5*60 = 30
For this case we must find a linear equation of the form:
![y = mx + b](https://tex.z-dn.net/?f=y%20%3D%20mx%20%2B%20b)
Where,
m: slope of the line
b: cutting point with vertical axis.
For the slope we have the following equation:
![m = \frac {y_ {2} -y_ {1}} {x_ {2} -x_ {1}}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%20%7By_%20%7B2%7D%20-y_%20%7B1%7D%7D%20%7Bx_%20%7B2%7D%20-x_%20%7B1%7D%7D)
Substituting values we have:
![m = \frac {6-5} {1-1}\\m = \frac {1} {0}](https://tex.z-dn.net/?f=m%20%3D%20%5Cfrac%20%7B6-5%7D%20%7B1-1%7D%5C%5Cm%20%3D%20%5Cfrac%20%7B1%7D%20%7B0%7D)
We observe that the slope of the line is not defined.
Therefore, the line is vertical.
Thus, the equation of the line is given by:
![x = 1](https://tex.z-dn.net/?f=x%20%3D%201)
Answer:
The equation of the line is given by:
![x = 1](https://tex.z-dn.net/?f=x%20%3D%201)
