I will give you some intuitive remarks for some inspiration on the proofs.
For the first one, notice that if m divides n then n = pm where p is a integer.
Since n and m are both natural numbers p then must be a natural number as well.
Now we know that basically we want to prove that if a is congruent to b mod n then a is congruent to b mod "a factor of n" (this is cause n = pm).
Tell me if you need more clarification.
For the second proof, I would just draw a Venn diagram and prove that the two intersections cover identical regions.

Third Rock Ventures sells all its merchandise on credit. It has a profit margin of 8%, days sales outstanding were 60 days based on 360 days in a year, receivables of R180 000, total assets of R4000 000, and a debt ratio of 0,75. What is the company's return on equity (ROE)?
Answer:
Step-by-step explanation:
First, we need to calculate the company's credit sales for the year:
Credit Sales = Receivables / (Days Sales Outstanding / 360)
Credit Sales = R180,000 / (60/360) = R1,080,000
Next, we need to calculate the company's net income:
Net Income = Profit Margin x Credit Sales
Net Income = 0.08 x R1,080,000 = R86,400
We can calculate the company's total equity as follows:
Total Equity = Total Assets x (1 - Debt Ratio)
Total Equity = R4,000,000 x (1 - 0.75) = R1,000,000
Finally, we can calculate the ROE:
ROE = Net Income / Total Equity
ROE = R86,400 / R1,000,000 = 0.0864 or 8.64%
Therefore, Third Rock Ventures' return on equity is 8.64%.
A fruitier had 300 oranges and apples at first.20%of apples were sold in the morning.the fruitier then stocked up another 35 oranges.the total numbers of oranges and apple became 298.how many apples were there at first?
Answer:
185 apples
Step-by-step explanation:
We have to work in reverse to find the original number of apples.
298-35= 263 apples and oranges after 20% apples sold
300-263 = 37 apples
37 apples = 20%
For total apples:
37 apples x 5 = 20% x 5
185 apples = 100% of apples
There were 185 apples at first

A prism is completely filled with 96 cubes that have edge length of 1/2 cm.
What is the volume of the prism?
Thank you for answering ⋄∵₊⁺⧭ʷ⧬⁺₊∵⋄
Answer:
Since the prism is completely filled with 96 cubes that have an edge length of 1/2 cm, we can find the volume of the prism by multiplying the number of cubes by the volume of each cube.
The volume of each cube is (1/2 cm)^3 = 1/8 cm^3.
The number of cubes is 96.
Therefore, the volume of the prism is:
volume = (number of cubes) x (volume of each cube)
volume = 96 x (1/8 cm^3)
volume = 12 cm^3
So, the volume of the prism is 12 cubic centimeters.
Fill in the table of value for the equation y = 2x + 1
Answer:
To fill in the table of values for the equation y = 2x + 1, we can choose different values of x and substitute them into the equation to find the corresponding values of y. For example:
x y
0 1
1 3
2 5
3 7
4 9
To get the value of y, we substitute each value of x into the equation and simplify:
When x = 0:
y = 2(0) + 1 = 1
When x = 1:
y = 2(1) + 1 = 3
When x = 2:
y = 2(2) + 1 = 5
When x = 3:
y = 2(3) + 1 = 7
When x = 4:
y = 2(4) + 1 = 9
Therefore, the table of values for the equation y = 2x + 1 is:
x y
0 1
1 3
2 5
3 7
4 9

Angela, Breanna, Christine, Debbie, and Esther are in a club and they need to pick two people to go to a
meeting. They write each person’s name on equally sized pieces of paper, put them in a hat, and mix the
papers thoroughly. Find the probability model for this chance process and use it to determine the probability
that Angela gets to go to the meeting.
So the probability that Angela gets to go to the meeting is 2/5.
What is probability?Probability is a measure of the likelihood or chance of an event occurring. It is a numerical value between 0 and 1, where 0 means that the event is impossible and 1 means that the event is certain. Probability can be calculated by dividing the number of favorable outcomes by the total number of possible outcomes. It is an important concept in many fields, including mathematics, statistics, physics, and engineering, and is used to make predictions, analyze data, and make decisions under uncertainty.
Here,
There are a total of 5 people in the club, so there are 10 possible pairs of people that could be chosen to go to the meeting. Since each pair is equally likely to be chosen, the probability of any particular pair being chosen is 1/10.
To determine the probability that Angela gets to go to the meeting, we need to count the number of pairs that include Angela. There are 4 other people in the club, so there are 4 possible pairs that include Angela. Therefore, the probability that Angela gets to go to the meeting is:
P(Angela) = number of pairs that include Angela / total number of pairs

A square wrestling mat has a perimeter of (12x−32)
feet. Write an expression in simplest form that represents the side length (in feet) of the mat.
Answer:
The perimeter of a square is given by the formula P = 4s, where s is the side length. In this case, we are given that the perimeter is (12x - 32) feet, so we can set up an equation:
P = 4s
(12x - 32) = 4s
To solve for s, we can divide both sides by 4:
(12x - 32)/4 = s
Simplifying the expression on the left:
3x - 8 = s
Therefore, the expression in simplest form that represents the side length of the square wrestling mat is 3x - 8 feet.

3.1 x 105 = 310,000
OB) 3.1 x 10 = 31
2.4 x 10 = 24
2.7 x 105 = 270,000
OC) 2.7 x 105 = 270,000
2.4 x 10¹ = 24
3.1 x 10¹ = 31
OD) 3.1 x 103 = 3,100
2.7 x 105 = 270,000
2.4 x 10 = 24

Which of the following contains the better choice with the correct reasoning?
O The Traditional IRA is the better choice because the employee will be taxed at a lower rate on lower earnings in retirement than during employment.
O The Roth IRA is the better choice because the employee will be taxed at a lower rate on lower eamings during employment than in retirement
O The Traditional IRA is the better choice because the employee will be taxed at a higher rate on lower earnings in retirement than during employment.
O The Roth IRA is the better choice because the employee will be taxed at a higher rate on lower eamings during employment than in retirement.
Based on the employee contribution, the Traditional IRA is the better choice because the employee will be taxed at a lower rate on lower earnings in retirement than during employment. The Option A is correct.
Why is Traditional IRA the best choice for the employee?The Traditional IRA allows the employee to make contributions on a pre-tax basis, which reduces the taxable income during the years of contribution. This reduces the tax liability during employment years in the 33% tax bracket. During retirement, the employee will be in the 15% tax bracket, which means they will pay a lower tax rate on the withdrawals from the Traditional IRA.
In contrast, the Roth IRA contributions are made with after-tax dollars, and the withdrawals during retirement are tax-free. Since the employee is currently in the 33% tax bracket, they will pay a higher tax rate on their current income than they would in retirement. Therefore, the Traditional IRA is a better choice for the employee in this scenario.

Expressions can be composed of variables, constants, and mathematical operations such as addition, subtraction, multiplication, division, exponents, and radicals.
We can simplify the expression inside the parentheses first and then subtract the fraction.
(5 5/6 + 1 3/4) - 4 7/12
= (33/6 + 7/4) - 55/12
= (11/2 + 7/4) - 55/12

= 87/12 - 275/60
= 87/12 - 11/4
= (29/4) - (33/12)
= (29/4) - (11/3)
To find the correct solution, we can simplify this expression:
(29/4) - (11/3) = (87/12) - (44/12) = 43/12
Therefore, the correct solution is C. (5 + 1 - 4) + (10/12 + 9/12 - 7/12) = 2 + 1 = 3.

How to obtain the average rate of change?The average rate of change of a function is given by the change in the output of the function divided by the change in the input of the function. Hence we must identify the change in the output, the change in the input, and then divide then to obtain the average rate of change.
For Maine, in 9 days, the temperature fell by 13.5ºF, hence the rate is given as follows:
-13.5/9 = -1.5ºF/day.
For Connecticut, in 2.5 days, the temperature fell by 6.25ºF, hence the rate is given as follows:

Zoe has 7/3 of an ounce of children’s ibuprofen. A full dose for Zoe’s one-year-old is 2/5 of an ounce. To figure out exactly how many doses she has left, she drew the diagram below. But she realized that her diagram shows how many 1/5-ounce doses are in 7/3 of an ounce. How can she use her diagram to figure out how many 2/5-ounce doses she has? Explain using words and diagrams.
It should be noted that to use the diagram to figure out how many 2/5-ounce doses Zoe has, she can divide the 7/3-ounce amount into equal parts of 2/5 ounce.
How to explain the word problemOne way to do this is to divide 2/5 by 1/5 to get the number of 1/5-ounce portions that make up a 2/5-ounce dose, which is 2. Then, divide 7/3 by 2/5 to get the total number of 2/5-ounce doses she has.
So, using the diagram, Zoe can count the number of 1/5-ounce portions she has, and then divide that number by 2 to find out how many 2/5-ounce doses she has.
Alternatively, Zoe could redraw the diagram to show 2/5-ounce portions instead of 1/5-ounce portions, and then count the number of 2/5-ounce portions she has. She would need to divide the original diagram into equal parts of 2/5 ounce by drawing lines to divide each square into two parts. Then she can count the number of squares that represent a 2/5-ounce dose.

the cost for3.8 pounds of shrimp is 18.05 . find the unit price in dollars per pound. if necessary round it to the nearest cent
The unit price in dollars per pound is $4.75 (rounded to the nearest cent).
What is profit and loss?
Mathematicians use the profit and loss formula to calculate market prices for goods and to assess how lucrative a company is. There is a selling price and a cost price for every commodity. We can determine the profit made or loss suffered for a specific commodity based on the values of these prices. Cost price, fixed, variable, and semi-variable costs, selling price, marked price, list price, margin, etc. are some of the key words that are discussed in this article.
To find the unit price in dollars per pound, we need to divide the total cost by the total weight:
Unit price = Total cost / Total weight
In this case, the total weight is 3.8 pounds and the total cost is $18.05.
Unit price = $18.05 / 3.8 pounds
Unit price = $4.75 per pound (rounded to the nearest cent)
Therefore, the unit price in dollars per pound is $4.75 (rounded to the nearest cent).

13. The profit, in thousands of dollars, from the sale of x kilogram of coffee bean can be modelled by the function () = 5−400 +600 . a) State the asymptotes and the intercepts. Then, sketch a graph of this function using its key features. (5 pts) b) State the domain and range in this context. (2 points) c) Explain the significance of the horizontal asymptote. (1 point) d) Algebraically, find how much amount of tuna fish, in kg, should be sold to have a profit of exactly $4000? (4 points) SOLUTION
Answer: a) The profit function can be written as:
P(x) = 5x - 400x + 600
To find the asymptotes, we can look at the denominator of the second term, which is (x - 3). This means that there is a vertical asymptote at x = 3. To find the intercepts, we can set P(x) = 0:
5x - 400x + 600 = 0
Solving for x, we get:
x = 1.5 and x = 2.5
Therefore, there are x-intercepts at (1.5, 0) and (2.5, 0). To sketch the graph, we can also note that the coefficient of x^2 is negative, which means that the graph is a downward-facing parabola.
b) The domain of the function is the set of all possible values of x, which in this context represents the amount of coffee sold. Since we cannot sell a negative amount of coffee, the domain is x ≥ 0.
The range of the function is the set of all possible values of P(x), which represents the profit. Since the coefficient of x^2 is negative, the maximum profit occurs at the vertex of the parabola. The vertex has x-coordinate:
x = -b/(2a) = -(-400)/(2(-200)) = 1
Therefore, the maximum profit occurs when x = 1. The vertex has y-coordinate:
P(1) = 5(1) - 400(1) + 600 = 205
Since the coefficient of x^2 is negative, the range is (-∞, 205].
c) The horizontal asymptote of the function is y = -400, which represents the long-term average profit per kilogram of coffee sold. This means that as x gets very large, the profit per kilogram approaches -400. This could happen, for example, if the cost of producing the coffee increased significantly while the price remained the same.
d) To find the amount of coffee that must be sold to make a profit of $4000, we can set P(x) = 4000 and solve for x:
5x - 400x + 600 = 4000
Simplifying, we get:
