Drug Name Half-life
-----------------------------------
Acetaminophen 1-4 hours
Ibuprofen 1.8-2 hours
Loratadine 8.4 hours
Lithium 8 hours
Diphenhydramine 5.3-11.7 hours
The table above displays the half-lives of 5 common house hold drugs. The half-life (h) is the time is takes for a substance to reduce to half its initial value (A0). Half life can be used to solve for the amount (A) of a substance left after t time by using the following equation:
A=A^0⋅(12)^t/h
If Scott was administered 300 mg of Lithium, which of the following represents how much lithium, rounded to the nearest hundredth of a mg, could be left in Scott's blood stream after 12 hours?
Select one:
A. 157.23
B. 106.07
C. 212.17
D. 188.99
Answers
Answer:
B. 106.07
Step-by-step explanation:
To make use of the given formula for amount remaining, we need to know the original amount (300 mg), the elapsed time (12 h), and the half-life of the substance of interest (8 h).
SetupUsing the given formula with the relevant values, we have ...
A = (300 mg)·(1/2)^(12/8)
EvaluationUsing a calculator to evaluate this expression, we find the amount of Lithium remaining in Scott's system after 12 hours to be ...
A ≈ 106.07 mg

The distance that a object covered in time was measured and recorded in the table. What equation would describe this motion?
y = 2x
y = 4x + 2.5
y = 4x + 4
y = 1.5x + 4.0
Answers
Answer:y = 1.5x + 4.0
Step-by-step explanation:
This is because the equation relates the distance traveled (y) to the time elapsed (x) through a linear relationship with a slope of 1.5, which represents the object's speed in meters per second, and a y-intercept of 4.0 meters, which represents the initial position of the object at time zero.
I'm pretty sure.
The equation that describes the motion of the object is y = 2x (option a)
Let's calculate the slope (m) using the values from the table. We take any two points (x₁, y₁) and (x₂, y₂) from the table:
(x₁, y₁) = (1, 2.0)
(x₂, y₂) = (5, 10.0)
The slope (m) is given by:
m = (y₂ - y₁) / (x₂ - x₁)
m = (10.0 - 2.0) / (5 - 1)
m = 8.0 / 4
m = 2.0
Now that we have the slope (m), we can determine the equation:
y = mx + b
Using one of the points from the table (1, 2.0) and the calculated slope (m = 2.0), we can solve for the y-intercept (b):
2.0 = 2.0 * 1 + b
2.0 = 2.0 + b
b = 2.0 - 2.0
b = 0
So, the Answer is option (a) y = 2x

How many cuts do you need to cut a stick into:
6 parts?
11 parts?
x parts?
Answers
Answer:
5,10,1.
Step-by-step explanation:
I'm not sure about the last one but I tried. hope this helped.
Answer:
5 cuts, 10 cuts, and for the last one it is an equation.
x parts - 1 = amount of cuts for x parts.
Step-by-step explanation:
I cannot upload an image but I can represent a half image/text to show how to find out the number of cuts.
Here is a "stick" that has been cut into 6 parts.
_ _ _ _ _ _
If you count the number of cuts in the "stick", you can tell it is 5 cuts, which is one less than 6. Let's try cutting a stick into 11 parts now.
_ _ _ _ _ _ _ _ _ _ _
As you can see, there are 10 cuts in the "stick". Therefore, you can use the equation, x-1 = amount of cuts, where x represents the number of parts the stick has been cut into.
The final answer:
5 cuts
10 cuts

Hayden drives a taxi cab and receives $200 a day plue $0.25 for every mile he drives. He is saving up for a new laptop that costs about $1800. If Hayden drives an average of 300 miles per day, how many days will he have to drive to save enough money to buy the laptop?
Answers
Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.
Given:
Daily base pay = $200
Earnings per mile driven = $0.25
Cost of the laptop = $1800
Average miles driven per day = 300
The basic arithmetic operations have been used to solve this question
1. Calculating the total earnings per day.
Total earnings per day = Daily base pay + (Earnings per mile driven × Average miles driven per day)
Total earnings per day = $200 + ($0.25 × 300)
Total earnings per day = $200 + $75
Total earnings per day = $275
2. Determining the number of days required to save enough money for the laptop.
Number of days = Cost of the laptop ÷ Total earnings per day
Number of days = $1800 ÷ $275
Number of days ≈ 6.545 (rounded to the nearest whole number)
Therefore, Hayden will have to drive for approximately 7 days to save enough money to buy the laptop.
