While these examples demonstrate some practical applications, divisibility rules are primarily mathematical tools that assist in simplifying calculations, verifying results, and understanding number properties.
Divisibility rules can be applied in various real-life scenarios, particularly in mathematics, finance, and everyday calculations. Here are a few examples:
Checking for even or odd numbers: The divisibility rule for 2 states that a number is divisible by 2 if its last digit is even (0, 2, 4, 6, or 8). This rule can be helpful when determining if a given quantity or count is even or odd. For example, in inventory management, you can quickly estimate the number of items in a collection by checking the parity of the count.
Divisibility by 3: The divisibility rule for 3 states that a number is divisible by 3 if the sum of its digits is divisible by 3. This rule can be useful when dealing with numbers or quantities that need to be evenly distributed or divided.
Divisibility by 9: The divisibility rule for 9 states that a number is divisible by 9 if the sum of its digits is divisible by 9. This rule can be applied in various financial calculations, such as checking if a large number is divisible by 9 to verify the accuracy of calculations involving money, invoices, or balances.
Divisibility by 10: The divisibility rule for 10 states that a number is divisible by 10 if its last digit is 0. This rule is often used in practical situations like determining if a given quantity can be divided evenly into groups of 10 or used in financial transactions involving rounding to the nearest multiple of 10.
Checking prime numbers: Divisibility rules can also help in determining whether a number is prime. For example, the rule that states a number is not divisible by any number greater than its square root can be used to quickly eliminate potential factors when checking for primality.

Answer: 99 in²
Step-by-step explanation:
We can use the given formula for a triangular prism. We will substitute our known values and solve.
Surface Area = length * base perimeter + (2 × base area)
Surface Area = length * (1.5 in + 2 in + 2.5 in) + (2 × [tex]\frac{bh}{2}[/tex])
Surface Area = 16 * (6 in) + (2 × [tex]\frac{(2\;in)(1.5\;in)}{2}[/tex])
Surface Area = 16 in * (6 in) + (3 in²)
Surface Area = 96 in² + 3 in²

In a village of 320 adults, each of them does at least farming or trading. 5/8 of them do farming and 75% of these who do farming are involved in trading. a. Find the number of people who are involved in: i. Farming ii. Trading. b. How many of the people are involved in exactly two activities?
c. Find the number of people who do only one activity.
d. What percentage of the people are traders only?
e. What is the probability of selecting an adult from the village at random who is a farmer but not a trader?
Answer:
please see answers below
Step-by-step explanation:
i) 5/8 X 320 = 200 people
ii) 0.75 X 200 = 150 (people in farming but also trade). only trade = 320 - 200 = 120.
number of people in trade = 150 + 120 = 270.
b) 0.75 X 5/8 = 3/4 X 5/8 = 15/32 = 150 people (both farm and trade).
c) only farming = 0.25 X 5/8 = 1/4 X 5/8 = 5/32 = 50.
only trade = 320 - 50 (only farm) - 150 (both farm and trade) = 120.
so, only do one activity = 50 + 120 = 170.
d) traders only = 120/320 = 3/8 = 37.5%
e) P(farmer only) = 50/320 = 0.15625

The slope of the line that passes through given points is -0.87. Option B is the correct answer.
In mathematics, slope is usually defined by the letter "m" and includes the change in y coordinate (vertical change) divided by the change in x coordinate (horizontal shift) between two points on a line.
We know that slope of a line that passes through two points is :
slope, [tex]m = \frac{y_{2} - y_{1} }{x_{2}-x_{1} }[/tex]
The given points are (-3.9,4.1) and (5.5,-4.1).
y2 = -4.1
y1 = 4.1
x2 = 5.5
x1 = -3.9
Substituting all these values in the above equation we get,
slope, [tex]m = \frac{-4.1 - (4.1)}{5.5 - (-3.9)}[/tex]
m = -8.2 / 9.4
m = -0.87
So, the slope of the line formed by given points is -0.87. Therefore , option B is correct answer.

Ki must travel to Atlanta to meet a client. She is starting from Memphis at
5:30 am. She gets to Atlanta at 3:00 pm. The total distance she traveled 391
miles. How fast did Ki travel if she kept a steady speed with no stop?
Ki traveled at an average speed of approximately 41.05 miles per hour without any stops.
To calculate the average speed at which Ki traveled from Memphis to Atlanta, we can use the formula:
Average Speed = Total Distance / Total Time
First, let's calculate the total time taken for the journey. Ki started from Memphis at 5:30 am and arrived in Atlanta at 3:00 pm, which is a total of 9.5 hours.
Next, we divide the total distance traveled, which is 391 miles, by the total time taken, which is 9.5 hours:
Average Speed = 391 miles / 9.5 hours
Calculating this, we find that Ki's average speed was approximately:
Average Speed ≈ 41.05 miles per hour
Therefore, Ki traveled at an average speed of approximately 41.05 miles per hour without any stops.

√3*√5*√12 i need to simplify please help
Step-by-step explanation:
To simplify the expression √3 * √5 * √12, you can combine the square roots and simplify the numbers under the radicals.
Step 1: Simplify the numbers under the radicals:
√3 = √(3) (The square root of 3 cannot be simplified further because 3 is a prime number.)
√5 = √(5) (The square root of 5 cannot be simplified further because 5 is a prime number.)
√12 = √(4 * 3) (The number 12 can be expressed as the product of 4 and 3, and the square root of 4 simplifies to 2.)
√12 = 2√(3)
Step 2: Combine the simplified square roots:
√3 * √5 * √12 = √(3) * √(5) * 2√(3)
Step 3: Apply the rule of multiplying square roots:
√(3) * √(5) = √(3 * 5) = √15
Step 4: Substitute the simplified square roots back into the expression:
√3 * √5 * √12 = √15 * 2√(3)
Step 5: Simplify the expression further:
√15 * 2√(3) = 2√(15) * √(3) = 2√(15 * 3) = 2√(45)
Step 6: Simplify the number under the square root:
2√(45) = 2√(9 * 5) = 2√(9) * √(5) = 2 * 3 * √(5) = 6√(5)
Therefore, the simplified form of √3 * √5 * √12 is 6√5.

The value of x for which the two lines are parallel is given as follows:
x = 60º.
What are consecutive interior angles?We have two parallel lines that are cut by a transversal, and the two angles are between the parallel lines and on the same side of the transversal, meaning that they are consecutive interior angles.
Consecutive interior angles are supplementary, meaning that the sum of their measures is of 180º, hence the value of x can be found as follows:
x + 2x = 180
3x = 180º
x = 180º/3
x = 60º.

David and Ken took part in a cycling race. Both of them did not change their speed throughout the race. David completed the race in 5 hours while Ken took 7 hours. Ken's average speed was 9.8 km/h less than David's average speed.
A) What was David average speed
B)What was the distance of the cycling race?
Let's assume David's average speed is S km/h.
A) To find David's average speed, we can use the formula: Speed = Distance / Time.
David completed the race in 5 hours, so his speed is S km/h. Therefore, we have:
S = Distance / 5
B) Ken's average speed is 9.8 km/h less than David's average speed, which means Ken's average speed is (S - 9.8) km/h.
Ken took 7 hours to complete the race, so we have:
S - 9.8 = Distance / 7
Now, we can solve the system of equations to find the values of S and Distance.
From equation (1): S = Distance / 5
Substitute this into equation (2):
Distance / 5 - 9.8 = Distance / 7
Multiply both sides of the equation by 35 to eliminate the denominators:
7 * Distance - 35 * 9.8 = 5 * Distance
7 * Distance - 343 = 5 * Distance
Subtract 5 * Distance from both sides:
2 * Distance - 343 = 0
Add 343 to both sides:
2 * Distance = 343
Divide both sides by 2:
Distance = 343 / 2 = 171.5 km
Therefore, the distance of the cycling race is 171.5 kilometers.
To find David's average speed, substitute the distance into equation (1):
S = Distance / 5 = 171.5 / 5 = 34.3 km/h
So, David's average speed was 34.3 km/h.[tex][/tex]
Answer:
A) 34.3 km/h
B) 171.5 km
Step-by-step explanation:
Since Ken's average speed is said to be 9.8km/h less than David's average speed, and we know that Ken's average speed is dependent on him traveling for 7 hours, then we have our equation to get the distance of the cycling race:
[tex]\text{Ken's Avg. Speed}=\text{David's Avg. Speed}\,-\,9.8\\\\\frac{\text{Distance}}{7}=\frac{\text{Distance}}{5}-9.8\\\\\frac{5(\text{Distance})}{7}=\text{Distance}-49\\\\5(\text{Distance})=7(\text{Distance})-343\\\\-2(\text{Distance})=-343\\\\\text{Distance}=171.5\text{ km}[/tex]
This distance for the cycling race can now be used to determine David's average speed:
[tex]\text{David's Avg. Speed}=\frac{\text{Distance}}{5}=\frac{171.5}{5}=34.3\text{ km/h}[/tex]
Therefore, David's average speed was 34.3 km/h and the distance of the cycling race was 171.5 km.
What value of x and y will make quadrilateral KLMN a parallelogram?
x + 3y
5y
2(x + y - 1)
H
11
and y =
20
Answer:
x = 6 , y = 4
Step-by-step explanation:
for the figure to be a parallelogram , the opposite sides must be congruent, that is
5y = 20 ( divide both sides by 5 )
y = 4
and
2(x + y - 1) = x + 3y ← distribute parenthesis on left side by 2
2x + 2y - 2 = x + 3y ← substitute y = 4
2x + 2(4) - 2 = x + 3(4)
2x + 8 - 2 = x + 12
2x + 6 = x + 12 ( subtract x from both sides )
x + 6 = 12 ( subtract 6 from both sides )
x = 6
A man has 14 coins in his pocket, all of which are dimes and quarters. If the total value of his change is $2.15, how many dimes and how many
Answer:
9 dimes and 5 quarters----------------------
Let d be the number of dimes and q be the number of quarters.
We can set up two equations based on the information given:
d + q = 14 (14 coins in total) 0.10d + 0.25q = 2.15 (total value of his change is $2.15)Use substitution here:
d = 14 - q (from the first equation) 0.10(14 - q) + 0.25q = 2.15 (substituting into the second equation) 1.40 - 0.10q + 0.25q = 2.15 0.15q = 0.75 q = 5So he has 5 quarters.
We can plug that back into either equation to find the number of dimes:
d + 5 = 14 d = 9So he has 9 dimes and 5 quarters.
Reema wants to build a coat rack for the front hallway. The wall is
4 feet long, and the piece of wood she has for the rack is 28 1/4
inches long. She wants to center the coat rack on the wall. There
needs to be an equal amount of space, about 7 or 8 inches,
between the coat hooks. The first and last hooks should be no
less than 1 3/4 inches from either end of the wood. How many
hooks should Reema use? What is the distance between the
hooks? What is the distance of each hook from the left edge of
the wood?
Reema should use 3 hooks. The distance between the hooks is approximately 4 inches, and the distances of each hook from the left edge of the wood are approximately 1.75 inches, 5.75 inches, and 9.75 inches.
Given:
Wall length: 4 feet
Wood length: 28 inches
Space between hooks: about 7 or 8 inches
Minimum distance from each end: 1 3/4 inches
To center the coat rack on the wall, we need to find the remaining space on either side of the wood after accounting for the minimum distances from each end.
Convert measurements to inches:
Wall length: 4 feet = 48 inches
Calculate the available space for the wood on the wall:
Available space on each side = (Wall length - Wood length) / 2
Available space on each side = (48 inches - 28 inches) / 2
Available space on each side = 20 inches / 2
Available space on each side = 10 inches
Determine the number of hooks and the space between them:
Space between hooks: about 7 or 8 inches
Let's assume we choose a space of 8 inches between hooks for this calculation.
Remaining space for hooks = Wood length - (Minimum distance from each end × 2)
Remaining space for hooks = 28 inches - (1 3/4 inches × 2)
Remaining space for hooks = 28 inches - (3 1/2 inches)
Remaining space for hooks = 28 inches - 7/2 inches
Remaining space for hooks = 28 inches - 3.5 inches
Remaining space for hooks = 24.5 inches
Number of hooks = Remaining space for hooks / Space between hooks
Number of hooks = 24.5 inches / 8 inches (approximately)
Number of hooks ≈ 3.06 (rounded to the nearest whole number)
Since we cannot have a fraction of a hook, we'll round down to 3 hooks.
Calculate the distance between hooks:
Distance between hooks = Space between hooks / (Number of hooks - 1)
Distance between hooks = 8 inches / (3 hooks - 1)
Distance between hooks = 8 inches / 2
Distance between hooks = 4 inches
Calculate the distance of each hook from the left edge of the wood:
Hook 1 distance from the left edge = Minimum distance from each end
Hook 2 distance from the left edge = Minimum distance from each end + Distance between hooks
Hook 3 distance from the left edge = Minimum distance from each end + (Distance between hooks × 2)
Using the given minimum distance from each end of 1 3/4 inches (or 1.75 inches), we can calculate the distances for each hook:
Hook 1 distance from the left edge = 1.75 inches
Hook 2 distance from the left edge = 1.75 inches + 4 inches
Hook 2 distance from the left edge = 5.75 inches
Hook 3 distance from the left edge = 1.75 inches + (4 inches × 2)
Hook 3 distance from the left edge = 9.75 inches
So, Reema should use 3 hooks. The distance between the hooks is approximately 4 inches, and the distances of each hook from the left edge of the wood are approximately 1.75 inches, 5.75 inches, and 9.75 inches.

Her marginal cost of production is constant at $20 for each additional unit (or jacket) produced. If she behaves like a monopolist, what is the number of jackets she will sell?
a. 1
b. 3
c. 4
d. 5
The number of jackets Meera will sell if she behaves like a monopolist is 3( option B).
To determine the number of jackets Meera will sell if she behaves like a monopolist, we need to compare the marginal revenue (MR) and marginal cost (MC) of producing and selling additional jackets. Meera can sell jackets at various price points depending on the quantity sold, but as she behaves like a monopolist, we consider the revenue and costs associated with a given production level.
From the pricing information given, we can determine her total revenue function, R(x), as follows:
- For 1 jacket, R(1) = 40
- For 2 jackets, R(2) = 70
- For 3 jackets, R(3) = 90
- For 4 jackets, R(4) = 100
- For 5 jackets, R(5) = 100
To determine her marginal revenue function, MR(x), we find the change in revenue from selling an additional jacket. From the data given, we can see that MR is not constant and decreases as the quantity sold increases. Specifically:
- For 1 jacket, MR(1) = 40 - 0 = 40
- For 2 jackets, MR(2) = 35 - 40 = -5
- For 3 jackets, MR(3) = 30 - 35 = -5
- For 4 jackets, MR(4) = 25 - 30 = -5
- For 5 jackets, MR(5) = 20 - 25 = -5
Meera's marginal cost of production is given as a constant $20 for each additional jacket produced, so MC(x) = 20 for all values of x.
To maximize her profits, Meera should produce and sell jackets up to the point where MR(x) = MC(x), which represents the level of production that equates the revenue from selling an additional jacket with the cost of producing that jacket. This happens at the output level of 3, where MR(3) = -5 = MC(3) = 20.(option-b)

Find the surface area of the
regular hexagonal prism.
3.5 cm
The surface area is cm Superscript 2
4 cm
11 cm
...
Answer:
348 cm²
Step-by-step explanation:
In this problem, we are asked to find the surface area of the regular hexagonal prism. We can use the formula:
[tex]SA = 2A + (P \cdot h)[/tex]
where [tex]A[/tex] is the area of the prism's hexagonal faces, [tex]P[/tex] is the perimeter of the hexagonal faces, and [tex]h[/tex] is the prism's height.
We can solve for the area of the hexagonal faces by splitting it into 6 triangles and multiplying the area of each triangle by 6.
[tex]A = 6\left(\dfrac{1}{2} bh\right)[/tex]
where [tex]b[/tex] is the triangle's base and [tex]h[/tex] is the triangle's height.
[tex]A = 6\left(\dfrac{1}{2}\cdot 4 \cdot 3.5\right)[/tex]
[tex]A = 6\left(2 \cdot 3.5\right)[/tex]
[tex]A = 12 \cdot 3.5[/tex]
[tex]A = 42\text{ cm}^2[/tex]
We can solve for the perimeter by multiplying one side length by 6.
[tex]P = 6(4) = 24\text{ cm}[/tex]
We are given that the height of the prism is 11 cm.
[tex]h = 11\text{ cm}[/tex]
Finally, we can solve for the surface area of the prism by plugging these values into the above formula.
[tex]SA = 2A + (P \cdot h)[/tex]
[tex]SA = 2(42) + (24 \cdot 11)[/tex]
[tex]SA = 84 + 264[/tex]
[tex]\boxed{SA = 348 \text{ cm}^2}[/tex]

The children's reading room of a library is shaped like a triangle. Two perpendicular sides of the room measure 12 feet and 17 feet. What's the area of the room?
a.29 squared feet
b.102 squared feet
c.120 squared feet
d.204 squared feet
Answer: B 102
Step-by-step explanation: The perpendicular sides of the room tells us that it is a right triangle.
To find our the area of the triangle you use the formula [tex]\frac{base*height}{2}[/tex]base*height/2
We plug in 12feet and 17 feet for the base and height
We get [tex]\frac{12*17}{2}[/tex]
12 and 2 cancel out so our new equation is 6*17 squared feet
So our answer is 102 square feet
