Answer:
t = ln(0.5)/-r
Step-by-step explanation:
The decay rate parameter is missing. I will assume a value of 4% per day.
The exponential decay is modeled by the following equation:
A = A0*e^(-r*t)
where A is the mass after t time (in days), A0 is the initial mass and r is the rate (as a decimal).
At half-life A = A0/2, then:
A0/2 = A0*e^(-0.04*t)
0.5 = e^(-0.04*t)
ln(0.5) = -0.04*t
t = ln(0.5)/-0.04
t = 17.33 days
In general the half-life time is:
t = ln(0.5)/-r
Answer:
![Boxes = 1008oz](https://tex.z-dn.net/?f=Boxes%20%3D%201008oz)
Step-by-step explanation:
Given
![Boxes = 42](https://tex.z-dn.net/?f=Boxes%20%3D%2042)
![1\ box = 24oz](https://tex.z-dn.net/?f=1%5C%20box%20%3D%2024oz)
Required
Determine the number of ounces ordered
The question is incomplete, as the numbers to drag are not given. However, the alternate solution is as follows:
![Boxes = 42\ boxes](https://tex.z-dn.net/?f=Boxes%20%3D%2042%5C%20boxes)
This can be rewritten as:
![Boxes = 42 * 1\ box](https://tex.z-dn.net/?f=Boxes%20%3D%2042%20%2A%201%5C%20box)
Substitute 24oz for 1 box
![Boxes = 42 * 24oz](https://tex.z-dn.net/?f=Boxes%20%3D%2042%20%2A%2024oz)
![Boxes = 1008oz](https://tex.z-dn.net/?f=Boxes%20%3D%201008oz)
<em>Hence, a total of 1008 ounces were ordered</em>
Answer:
X = 2550
Step-by-step explanation:
Convert 12% to a decimal:
⇒ 12% = 12/100 = 0.12
12% of X is 306
⇒ 0.12X = 306
⇒ X = 306 ÷ 0.12
⇒ X = 2550
