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

In this discussion, you have the opportunity to have some hands-on fun. With a
tape measure determine the diameter and circumference of at least three circular
objects. Calculate the ratio of the circumference to the diameter.
Take a look at Khianna's post:
I used a tape measure to determine the diameter and circumference of an orange
juice can, a trash can, and a lamp shade. Here is what I found:
Circumference
4.65 in
Ratio
3.1
OJ Can
Diameter
1.5 in
8 in
6 in
Trash Can
3.12
24.96 in
18.8 in
Lamp Shade
3.13
The ratio was close to Pi, but never actually equaled 3.14, maybe because of an
error when I measured the objects.
After you complete your measurements, use the diameter to calculate the exact
circumference of each object as shown on the next page.
Use the diameter to calculate the exact.value of the circumference of each object.
Look how Khianna added to her post:
If I used the diameter I measured, the exact value for each object's circumference would be: diameter or circumference OJ can 1.5 in 1.5 pi and 4.71 in trashcan eight in a pie in 25.12 in lampshade six and six pie and 18.84 in
Use a measuring tape to determine the diameter and approximate for conference of three household items
Find the ratio of the circumference to the diameter for each circle identify what the value of this ratio should be
Use pi and the diameter to calculate the exact value of the circumference

A. less than 7 cm
B. between 7 cm and 8 cm
C. between 8 cm and 9 cm
D. greater than 9 cm
2. The net below shows equilateral triangles. What is the total surface area of the triangular pyramid in square feet?
Answers
Answer:
65^2
Step-by-step explanation:
if you woulndt mind giving me brainliest im trying to rank up, only if u dont mind.
#1:
Between 8 cm and 9 cm
Work:
SA = 6s^2
390 = 6 s^2
390/6 = 6s^2 /6
65 = s^2
sqrt(65) = s
s = 8.06
#2:
The total surface area of the triangular pyramid is 107 * square feet.
What is a triangular pyramid?
Take a triangle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first triangle and when they're taken together, they form a closed object, called as a triangular pyramid.
We are given that;
The length of median from outer triangle to side of the inner triangle is 8 ft
Side of inner equilateral triangle is 12 ft
Now,
First, we can find the height of the outer equilateral triangle using the Pythagorean theorem:
a is half the length of the side of the inner triangle (6 ft), m is the length of the median (8 ft), and b is the length of the side of the outer triangle (unknown).
a^2 + (m/2)^2 = b^2
b^2 = 6^2 + 8^2/4
b^2 = 36 + 4
b^2 = 40
b = sqrt(40)
b = 2 * sqrt(10)
So the height of the outer triangle is:
h = b * sqrt(3)/2
h = sqrt(30)
Now we can find the area of each equilateral triangle using the formula:
A = (sqrt(3)/4) * s^2
For the inner triangle:
A_inner = (sqrt(3)/4) * 12^2
A_inner = 36 * sqrt(3)
For the outer triangle:
Now we can find the area of the base, which is just the area of the inner equilateral triangle:
A_base = A_inner
A_base = 36 *
Finally, we can find the surface area of the triangular pyramid by adding the areas of the four triangles and the base:
SA = A_inner + 3 * A_outer + A_base
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.

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
