Answer:

The correct option:  x + y = 6

Step-by-step explanation:

In a Cartesian system or a coordinate system, the abscissa is the value of the horizontal (x) value and the ordinate is the value of the vertical (y) value.

So, The sum of the abscissa and the ordinate = x + y when written as an algebraic expression.

Since given that The sum of the abscissa and the ordinate is six

So,  the correct equation is x + y = 6

huh cant see nun............

Answer:

Step-by-step explanation:

Let the number be x and y

xy = 378.......(1)

x + y = 41......(2)

Making y as subject in (2)

y = 41 - x......(3)

Substitute it in (1)

x(41 - x) = 378

41x - x² = 378

x² - 41x + 378 = 0

x² - 27x - 14x + 378 = 0

(x² - 27x) - (14x - 378) = 0

x(x - 27) - 14(x - 27) = 0

(x -14)(x - 27) = 0

x - 14 = 0 or x - 27 = 0

x = 14 or x = 27

And y = 41 - x

When x = 14

y = 41 - 14 = 27

y = 27

When x = 27

y = 41 - 27 = 14

y = 14

The two numbers are 14 and 27.

One or many equations having the same number of unknowns that can be solved simultaneously called as simultaneous equation. And simultaneous equation is the system of equation.

Given:

Let the numbers are x and y.

Then,

the system of equations

xy = 378  {equation 1}

x + y = 41   {equation 2}

y = 41 - x

Then

x(41 - x) = 378

41x - x² = 378

x² - 41x + 378 = 0

x² - 27x - 14x + 378 = 0

(x² - 27x) - (14x - 378) = 0

x(x - 27) - 14(x - 27) = 0

(x -14)(x - 27) = 0

x - 14 = 0 or x - 27 = 0

x = 14 or x = 27

And y = 41 - x

When x = 14

y = 41 - 14 = 27

y = 27

When x = 27

y = 41 - 27 = 14

y = 14

Therefore, the  14 and 27 are the numbers.

Answer:

The rate of change for the interval shown in the table is 1 , so the function is a linear function.

Step-by-step explanation:

See the table attached.

The table shows selected points from a function.

Now, the given interval is x = 1 to x = 4.

For, x = 1, f(x) = 2 and for x = 4. the function f(x) = 5.

Therefore, the rate of change for the interval shown in the table i.e slope of the line is [tex]\frac{5 - 2}{4 - 1} = 1[/tex] and it is constant throughout the interval so the function is a linear function. (Answer)

The rate of change for the interval shown in the table is constant , so the function is a linear function.

Note the following important points:

1. Linear Function:

If the difference between y values remains constant for any pair of consecutive points ([tex]y_2-y_1 = y_3-y_2 = y_4-y_3,[/tex]and so on), the function exhibits a constant rate of change, indicating a linear function. In this case, the rate of change would be the difference between two y values divided by the difference between their corresponding x values (e.g., [tex]\frac{(y_2-y_1)}{(x_2-x_1)}[/tex]).

2. Non-Linear Function:

If the difference between y values varies between consecutive points, the function would be non-linear. The specific type of non-linear function (e.g., quadratic, exponential) would require further analysis with more data points or additional information about the function's behavior.

In this case, as shown in the attached table, it is clear that

For [tex]x_1=1, y_1=f(x)=2[/tex].

For [tex]x_2=2, y_2=f(x)=3[/tex].

For[tex]x_3=, y_3=f(x)=4[/tex].

For [tex]x_4=, y_4=f(x)=5[/tex], and so on.

Thus the rate of change for the interval shown in the table or its slope is constant as evident from the following calculation.

[tex]\frac{(y_2-y_1)}{(x_2-x_1)}=\frac{3-2}{2-1}=1\\ \frac{(y_3-y_2)}{(x_3-x_2)}=\frac{4-3}{3-2}=1\\\frac{(y_4-y_3)}{(x_4-x_3)}=\frac{5-4}{4-3} =1[/tex].

So it is clear that, the rate of change for the interval shown in the table is constant , so the function is a linear function.

The intersection of the sets of outcomes of events A and B is the set of all outcomes that are common in both events A and B. This is a concept from set theory in mathematics.

The correct answer to the given question is option B.

The correct statement that best describes the intersection of the sets of outcomes of events A and B is 'The intersection of the sets is the set of all outcomes in events A and B'.

In mathematical terms, the intersection of two sets, often denoted as A ∩ B, is the set of elements which are in both A and B.

Thus, the intersection of two sets of outcomes of events A and B, would consequently be the set of all outcomes that are common in both events A and B.

This is mainly a concept from set theory, a fundamental part of mathematics that deals with the study of sets, which are collections of objects.

For instance, if the set A = {1, 2, 3} and the set B = {2, 3, 4}, then A ∩ B = {2, 3}. In this example, 2 and 3 are the outcomes that are common in both events A and B.

Introduction

Wrestling is a wonderful activity with many advantages for the student-athlete. It is a sport that is highly

competitive, exciting and satisfying. It is a sport that provides for individual and team competition. It is -

and should be - fun. Unfortunately, the practice of losing weight by not eating, restricting fluid intake and

over-exercising reduces the sport's fun. This information is presented to help clear up misconceptions

regarding wrestling and weight loss. I also hope to give some guidance to those who desire to manage

their weight properly in preparation for and during the wrestling season.

History and Stigma

For too long, the wrestling community has unthinkingly accepted the myth that to be a good wrestler, you

must cut weight. The generally accepted thinking is something like this: if your natural weight is 135

pounds, you may be a good wrestler at 135 pounds. But if you wrestle at 130 pounds, you'll be a better

wrestler. And if you can make it down to 125, you'll be a state champion. No facts support that widely held

view, yet wrestlers and parents subscribe to that faulty reasoning. Looking further back, many remember

the days that losing excessive weight was a specific practice and expectation among wrestlers. It was

supposed to teach sacrifice, commitment, and the idea of “No Pain, No Gain.”

Regardless of the current attitude of the majority of the wrestling community, the stigma that an unhealthy

loss of weight is a requirement of wrestling among outside observers sticks. The Virginia High School

League has followed national guidelines to establish rules that encourage healthy weight management

among wrestlers.

Current Regulations

Preseason weight certification is accomplished with three steps. The first is determining each wrestler’s

body fat percentage using skin fold calipers. Next, the wrestler completes a hydration test, to insure

against a dehydrated weight measurement, and the wrestler weighs in. The third step is the calculation of

the wrestler’s minimum wrestling weight based on 7% body fat for males and 12% for females. The

wrestler may not wrestle at a weight class below his minimum weight during the season. The wrestler is

also restricted from losing more then 1.5% body weight loss per week (official weigh-ins at certification,

matches, and tournaments are used for this calculation). A one-pound per month growth allowance is

provided to allow for the natural growth of this age group. The VHSL advises, and we have instituted,

daily weigh-ins before and after practice to monitor weight-loss and dehydration.

Additionally, the National Federation of State High School Associations has adopted several other rules to

guide coaches and wrestlers while managing their weight. Wrestlers are discouraged from wrestling at a

weight class more then one weight class above their certified weight.

The equation that models the situation of a wrestler's varying weight is w = x +/- 3.2, with x representing the normal weight. The minimum weight is 164.8 pounds and the maximum weight is 171.2 pounds.

To write an equation that models the situation, we can use the variables x and w to represent the normal weight and the varying weight, respectively. The equation can be written as w = x +/- 3.2, where the +/- sign represents that the weight can vary by as much as 3.2 pounds. Given that the normal weight is 168 pounds, the minimum weight would be 168 - 3.2 = 164.8 pounds, and the maximum weight would be 168 + 3.2 = 171.2 pounds.

2 BTUs/cubic foot.

Step-by-step explanation:

Suppose that 2 people exercising in an enclosed room are each generating about 2,400 BTUs of body heat per hour.

So, 2 people will produce (2400 × 2) = 4800 BTUs for 1 hour.

Now, the volume of the room with dimensions (20 ft by 12 ft by 10 ft) will be (20 × 12 × 10) = 2400 cubic feet.

Therefore, the number of BTUs per cubic foot will be produced  by [tex]\frac{4800}{2400} = 2[/tex] BTUs/cubic foot. (Answer)

Miranda can solve 1300 divided by 26 by using multiplication – specifically, by finding what number multiplies with 26 to result in 1300. She can break down the number 26 into smaller factors for easier estimation, using inverse operations to eventually find that 50 is the correct answer.

Using Multiplication to Solve Division Problems

Miranda was asked to solve the problem 1300 divided by 26. To use multiplication to solve this division problem, she can apply the reciprocal approach. Essentially, she can multiply 1300 by the reciprocal (the inverse) of 26. The reciprocal of a number 'a' is 1/a, so the reciprocal of 26 is 1/26. However, finding the reciprocal of 26 directly can be challenging, so we can use intuitive steps that simplify the problem.

For example, we could productively think about what number, when multiplied by 26, gives us 1300. This is a form of inverse operations. One way to approach this is to break down 26 into factors like 2 and 13, which might lead to simpler multiples to work with. She may start by estimating and refining her estimations by multiplying different numbers by 26 and seeing how close she gets to 1300. It’s a trial and error process, but eventually, she will find the correct answer of 50, as 26 multiplied by 50 equals 1300.

well...you know the business is gonna want to make a profit...so they would have to sell it for more then they bought it for.

I would say $ 60 or $ 80

Final answer:

Given the wholesale price of $45, the sensible retail prices to charge customers would be $60 and $80, as they both allow for covering costs and earning a profit, unlike $20 and $40, which would incur losses.

Explanation:

The question involves understanding wholesale and retail prices, essential concepts in economics and business mathematics. When a company buys an item at a wholesale price, it usually marks up the price when selling it at retail to cover costs and generate profit. Given the wholesale price of $45, the retail prices that make sense to charge customers would be those higher than $45 because selling at a lower price would result in a loss.

Both $60 and $80 are above the wholesale price and would allow the company to cover additional costs and earn a profit. $20 and $40 would not make sense as they are below the wholesale price, leading to a loss per item sold.

Part a) see the explanation

Part b) The graph in the attached figure

Step-by-step explanation:

The complete question is

The length of a snake in a video game doubles every minute. the function f(x)=10*(2)^x represents the length of the snake in centimeters. the time x=0 represents when the game started.

a) label the correct axes with "length (cm)" and"time (minutes)"

b) graph f(x)=10*(2)^x

Part a) we know that

we have a exponential function of the form

[tex]f(x)=a(b^x)[/tex]

where

f(x) -----> the length of a snake in a video game in centimeters

x ----> the time in minutes

a is the initial value or y-intercept of the linear equation

b is the base of the exponential equation

In this problem

[tex]f(x)=10(2^x)[/tex]

so

[tex]a=10\ cm[/tex] ---> initial value, value of y when the value of x is equal to zero[tex]b=2[/tex] ----> factor growth

[tex]b=(1+r)\\r=b-1=2-1=1[/tex]

[tex]r=100\%[/tex] ----> percent rate of change

Is a exponential growth function

Part b) Graph the function

To graph the function we need different points

assume different values of x and find the values of f(x)

For x=0 ---->  [tex]f(0)=10(2^0)=10[/tex] ----> point (0,10)

For x=1 ---->  [tex]f(1)=10(2^1)=20[/tex] ----> point (1,20)

For x=2 ---->  [tex]f(2)=10(2^2)=40[/tex] ----> point (2,40)

For x=3 ----> [tex]f(3)=10(2^3)=80[/tex] ----> point (3,80)

For x=4 ---->  f(4)=10(2^4)=160 ----> point (4,160)

Plot the points, connect them and draw the graph

see the attached figure

The original number is 64

Step-by-step explanation:

The given is:

We need to find the original number

Assume that the unit digit of the number is x and the ten digit is y

∵ The unite digit of the number is x

∵ The ten digit of the number is y

∵ The sum of the two digits is 10

- Add x and y, then equate the sum by 10

∴ x + y = 10 ⇒ (1)

∵ The value of the number is x + 10y

- Reverse the digits means y will be the unit digit and x will

   be the ten digit

∴ The new number is y + 10x

∵ The new number is 18 less than the original number

- That means their difference is 18, (the original number minus

   the new number = 18)

∴ (x + 10y) - (y + 10x) = 18

- Simplify the left hand side

∴ x + 10y - y - 10x = 18

- Add the like terms in the left hand side

∴ -9x + 9y = 18

- Divide both sides by 9

∴ -x + y = 2 ⇒ (2)

Now we have a system of equation to solve it

Add equation (1) and (2) to eliminate x

∴ 2y = 12

- Divide both sides by 2

∴ y = 6

- Substitute the value of y in equation (1) to find x

∵ x + 6 = 10

- Subtract 6 from both sides

∴ x = 4

∵ The original number is x + 10y

∵ x = 4 and y = 6

∴ The original number = 4 + 10(6) = 4 + 60 = 64

The original number is 64

To check the answer reverse the digits of the number

∵ The new number is y + 10x

∴ The new number = 6 + 10(4) = 6 + 40 = 46

∵ The original number is 64

∵ The new number is 46

∵ 64 - 46 = 18

∴ The new number is less than the original number by 18

Answer:

The total amount that Beyonce will pay for the chair is $9100.

Step-by-step explanation:

The Principal amount of chair  = $6500

Rate of interest  = 8%

Time = 5 years

Now, SIMPLE INTEREST  = [tex]\frac{P\times R \times T}{100}[/tex]

So, here calculating the interest on the chair, we get:

[tex]SI = \frac{6500 \times 5 \times 8}{100} = 2600[/tex]

So, the interest on the amount of chair for 5 years  is $2600.

Total amount of chair  = Original Amount of Chair + Interest Amount

                                      = $6500 + $2600 = $9100

Hence, the total amount that Beyonce will pay for the chair is $9100.

To find the total amount, calculate the interest and add it to the principal amount.

Simple interest is calculated using the formula: I = P * r * t, where I is the interest, P is the principal amount (loan), r is the annual interest rate, and t is the time in years. In this case, the principal amount (loan) is $6500, the annual interest rate is 8%, and the time is 5 years. So, the interest can be calculated as: I = 6500 * 0.08 * 5 = $2600.

To find the total amount that Beyonce will pay for the chair, we need to add the interest to the principal amount. The total amount is given by the formula: Total Amount = Principal + Interest. Therefore, Total Amount = 6500 + 2600 = $9100.

So, Beyonce will pay a total amount of $9100 for the chair, including the principal amount and interest.
