Answer:

the number of magazines purchased is 20

Step-by-step explanation:

As it is mentioned in the question that there is a total of 60 books + magazine altogether

Here we used the following equations

Let us assume the number of magazines be x

ANd, the number of books be y

x + y = 60 .............(1)

2x+ 3y = $160 ..........(2)

Now multiply with 2 in the equation 2

Then it comes

2x + 2y = 120

2x + 3y = 160

Solve these equations

y = 40

Now the x value is

x + 40 = 60

x = 20

Hence, the number of magazines purchased is 20

Answer:

T = 5 * ((7 * 10) + (6 * 9) + (3 * 2))

Step-by-step explanation:

The following mathematical expression would calculate the total number of materials in all of the classes which would be represented by the variable T. We would first multiply the quantity of a specific material in a single box by the number of boxes that exist for each separate material and then multiply that number by 5 since there are a total of 5 classrooms and all have the same quantity of the same materials.

T = 5 * ((7 * 10) + (6 * 9) + (3 * 2))

If we were to solve this we would see that there are a total of

T = 5 * ((7 * 10) + (6 * 9) + (3 * 2))

T = 5 * (70 + 54 + 6)

T = 5 * 130

T = 650

650 materials

Answer:

- 4 / 10 (or -2/5 if you need to simplify)

Step-by-step explanation:

using the point-slope formula, m = (y2-y1) / (x2 - x1)

using the ordered pairs, you get

m = (-2 - 2) / (3 - -7)

m = (-4) / (10)

m= -4/10

if you need to reduce, it's  -2/5

Step-by-step explanation:

Answer:

Step-by-step explanation:

In math, every function has a domain and a range.

Therefore, with this information given to us, we need to also know about coordinate pairs. Coordinate pairs are written in (x, y) form.

Functions are classified in four ways:

Finally, the domain and range should be written in ascending order. Therefore, the lowest number should be written first in the domain and the highest number should be written last.

Function 1

We are given the function: [tex]\text{ \{(-3, 3)}, (1, 1), (0, -2), (1, -4), (5, -1) \} }[/tex].

Using the information above, we can pick out our x and y-values from the function.

Values of Domain: -3, 1, 0, 1, 5

Values of Range: 3, 1, -2, -4, -1

Now, we need to arrange these in ascending order.

Domain Rearranged: -3, 0, 1, 1, 5

Range Rearranged: -4, -2, -1, 1, 3

Using these values, we can see what values we have.

For x-values:

x = -3: 1 value

x = 0: 1 value

x = 1: 2 values

x = 5: 1 value

For y-values:

y = -4: 1 value

y = -2: 1 value

y = -1: 1 value

y = 1: 1 value

y = 3: 1 value

Therefore, we can begin classifying this function. Because we have all separate y-values, we have a function. However, we have two of the same x-value, so we have an onto function.

Now, we can create our domain and range in the set. We use the same formatting given for the first function. We list the values in ascending order and list them in brackets to show that they are apart of a set.

The domain values are the x-values, so they are [tex]\text{ \{-3, 0, 1, 5\}}[/tex].

The range values are the y-values, so they are [tex]\text{ \{-4, -2, -1, 1, 3\}}[/tex].

Therefore, the domain and range for function one are defined, but this is not a function. Because the x-values repeat, it cannot be a function.

Function 2

We are given a table of values that needs to be translated into the set notation. This makes it easier to identify the values. We are given x-coordinates in the top row and y-coordinates in the bottom row. And, the table is set up to where the x-value directly above the y-value makes a coordinate pair. Using this, we can create the set function.

The set function is [tex]\text{ \{(-2, -7), (-1, -2), (0, 1), (1, -2), (2, -7)\}}[/tex].

Now, we can use the same method as above to pick out the x and y-values and reorder them to be from least to greatest.

Values of Domain: -2, -1, 0, 1, 2

Values of Range: -7, -2, 1, -2, -7

Now, we rearrange these.

Domain Rearranged: -2, -1, 0, 1, 2

Range Rearranged: -7, -7, -2, -2, 1

Now, we can check how many times the function presents each coordinate.

For x-values:

x = -2: 1 value

x = -1: 1 value

x = 0: 1 value

x = 1: 1 value

x = 2: 1 value

For y-values:

y = -7: 2 values

y = -2: 2 values

y = 1: 1 value

Now, we can classify the function. The x-values are unique, but the y-values are repeated. Therefore, because the x-values are assigned to one y-coordinate and they are unique, this is not an one-to-one function. Additionally, it cannot be an onto function because the y-values are not unique - they are repeated. Therefore, it is neither an one-to-one function or an onto function. If this function were graphed, it would actually reveal a parabola. However, it is still a function.

The domain values are the x-values, so they are [tex]\text{ \{-2, -1, 0, 1, 2\}}[/tex].

The range values are the x-values, so they are [tex]\text{ \{-7, -2, 1\}}[/tex].

Answer:

3%

Step-by-step explanation:

So in the most basic form, this question is asking what percent of $1,800 is $53.60. To find the percentage, we are simply going to divide both numbers then multiply by 100.

I'd like to add that by multiplying by 100, we change the number to a percentage. If we were to skip this step, it would just be a small decimal and not in the correct format needed for the answer.  

= (53.60/1800) x 100

= (0.02977777777) x 100

= 2.97777777778%

All that is left is to round to the tenths place

3. (9 + 5) + 3

4. 11

5. 1

6. 0

Step-by-step explanation:

1. Additive Identity means that if you add 0 with any number, the result would always be the number itself.

2. Commutative Property of Multiplication means that no matter what order, the result would still be the same when the arithmetic operations are all ×.

3. Associative Property of Addition means that no matter where the bracket is placed or which numbers are associated with each other using a bracket, the result would still be the same.

4. Multiplicative Identity means that if you times 1 with any number, the result would always be the number itself.

5. Multiplicative Inverse means that when the denominator of the first fraction is the same as the numerator of the second fraction and the numerator of the first fraction is the same as the denominator of the second fraction, the result would always be 1.

6. If you add the positive of a number with a negative of a number, the result would always be 0.

How to Calculate Percentages

There are many formulas for percentage problems. You can think of the most basic as X/Y = P x 100. The formulas below are all mathematical variations of this formula.

Let's explore the three basic percentage problems. X and Y are numbers and P is the percentage:

Find P percent of X

Find what percent of X is Y

Find X if P percent of it is Y

Read on to learn more about how to figure percentages.

1. How to calculate percentage of a number. Use the percentage formula: P% * X = Y

Example: What is 10% of 150?

Convert the problem to an equation using the percentage formula: P% * X = Y

P is 10%, X is 150, so the equation is 10% * 150 = Y

Convert 10% to a decimal by removing the percent sign and dividing by 100: 10/100 = 0.10

Substitute 0.10 for 10% in the equation: 10% * 150 = Y becomes 0.10 * 150 = Y

Do the math: 0.10 * 150 = 15

Y = 15

So 10% of 150 is 15

Double check your answer with the original question: What is 10% of 150? Multiply 0.10 * 150 = 15

2. How to find what percent of X is Y. Use the percentage formula: Y/X = P%

Example: What percent of 60 is 12?

Convert the problem to an equation using the percentage formula: Y/X = P%

X is 60, Y is 12, so the equation is 12/60 = P%

Do the math: 12/60 = 0.20

Important! The result will always be in decimal form, not percentage form. You need to multiply the result by 100 to get the percentage.

Converting 0.20 to a percent: 0.20 * 100 = 20%

So 20% of 60 is 12.

Double check your answer with the original question: What percent of 60 is 12? 12/60 = 0.20, and multiplying by 100 to get percentage, 0.20 * 100 = 20%

3. How to find X if P percent of it is Y. Use the percentage formula Y/P% = X

Example: 25 is 20% of what number?

Convert the problem to an equation using the percentage formula: Y/P% = X

Y is 25, P% is 20, so the equation is 25/20% = X

Convert the percentage to a decimal by dividing by 100.

Converting 20% to a decimal: 20/100 = 0.20

Substitute 0.20 for 20% in the equation: 25/0.20 = X

Do the math: 25/0.20 = X

X = 125

So 25 is 20% of 125

Double check your answer with the original question: 25 is 20% of what number? 25/0.20 = 125

Remember: How to convert a percentage to a decimal

Remove the percentage sign and divide by 100

15.6% = 15.6/100 = 0.156

Remember: How to convert a decimal to a percentage

Multiply by 100 and add a percentage sign

0.876 = 0.876 * 100 = 87.6%
