Salvatore purchased several magazines for $2 each and books for $3 each. If he spent $160 on a total of 60 books and magazines altogether, what would be the number magazines that Salvatore purchased?
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

The school math coach takes an inventory of math materials. He counts the materials for 5 different classes. Each class has 7 boxes of 10 pattern blocks, 6 boxes of 9 rulers, and 3 boxes of 2 calculators. Which expression shows the number of math materials?
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

Ramon earns $1,800 each month and pays $53.60 on electricity. To the nearest tenth of a percent, what
percent of Ramon's earnings are spent on electricity each month?
Ramon spends ____% of his eamings on electricity each month.
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

bowl. Calculate the probability of two blue marbles drawn when sampling is done with replacement
Step-by-step explanation:
Answer. The probability of picking a blue marble from the blue urn is 2/6=1/3. The probability of picking a blue marble from the black urn is 11/15. The two events are independent so the probability of a blue marble from each urn is the product of the two separate probabilities=1/3×11/15=11/45.

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%
Step-by-step explanation:
use the substitution method to solve the system of equations. choose the correct ordered pair

Answer:
Function 1 is not a function.The domain and range of the first function respectively are [tex]\text{ \{-3, 0, 1, 5\}}[/tex] and [tex]\text{ \{-4, -2, -1, 1, 3\}}[/tex].Function 2 is a function.The domain and range of the second function respectively are [tex]\text{ \{-2, -1, 0, 1, 2\}}[/tex] and [tex]\text{ \{-7, -2, 1\}}[/tex].Step-by-step explanation:
In math, every function has a domain and a range.
The domain of the function is all of the x-values for which the function is true. These can be found on the x-axis for every position at which the function exists or crosses the x-axis.The range of the function is all of the y-values for which the function is defined. The range can be found in the same manner as the domain - for every y-value at which the function exists, it is apart of the 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:
One-to-one functions: Functions are considered to be one-to-one functions if there are unique y-values (no y-values are repeated) and there is one x-value for every one y-value.Onto functions: Functions are considered to be onto functions if there are unique x-values. These x-values cannot repeat, but different x-values can be connected to the same y-values.Both one-to-one & onto: Functions are considered both one-to-one and onto when there is exactly one x-value for every one y-value.Neither one-to-one or onto: Functions are considered to be neither an one-to-one function or an onto function when they have two or more of the same y-values assigned to the same x-values. A function cannot exist if y-values are duplicated on a x-value.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].
