Step-by-step explanation:
y = mx + b
The b is the y intercept. This is where the graph crosses the y axis. Graph this first. The m is the slope. It is the rise over the run. You can make any number a fraction by putting it over 1. From the y-intercept you use the slope (rise/run) to graph the second point.
For example, if the slope is 1. then 1/1 would show your rise and run. Start when the y-intercept is and go up 1 and then 1 right. Connect the two points that you have graphed.
If the slope is 2/7, then from the y-intercept go up 2 and right 7. Graph that point and draw a line connecting that point to the point on the y-intercept.

Linda read 1/3 of her book on Friday. She reads 2/6 of the book on Saturday. On Sunday she reads the remaining 2/12 of the book. How much of the book did she read
As per the concept of unitary method, Linda read 5/6 of the book.
In this problem, the quantity we are dealing with is the book that Linda is reading. Let's call the total number of units in the book "x". Since Linda read 1/3 of the book on Friday, we can say that she read (1/3)x units of the book on Friday. Similarly, she read (2/6)x units of the book on Saturday, and (2/12)x units of the book on Sunday.
Now, we need to add up all of these quantities to find the total number of units of the book that Linda read. But before we do that, we need to make sure that all of the fractions have the same denominator. The smallest common multiple of 3, 6, and 12 is 12. So, we will convert all of the fractions to twelfths.
(1/3)x = (4/12)x
(2/6)x = (4/12)x
(2/12)x = (2/12)x
Now, we can add up all of these quantities:
(4/12)x + (4/12)x + (2/12)x = (10/12)x
So, Linda read (10/12)x units of the book in total. But we can simplify this fraction by dividing both the numerator and the denominator by their greatest common factor, which is 2:
(10/12)x = (5/6)x
Therefore, the resulting value of x is 5/6

A. Jace collected data on the distances electric vehicles can travel on one charge. He wants to show the average distance and the range an electric vehicle can travel on one charge.
Choose and make an appropriate display of the data
b. Jace wants to compare the range and shape of his electric-vehicle data to related data he collected on gas-powered vehicles. Choose and make appropriate data displays
A box-and-whisker plot is the appropriate data display for Jace's electric-vehicle data and gas-powered vehicle data, and it will give him a visual representation of the difference between the two datasets.
The appropriate data displays for Jace's electric-vehicle data and gas-powered vehicle data would be a box-and-whisker plot. This type of plot is a graphical representation of the five-number summary of a dataset. The five-number summary consists of the minimum, first quartile (Q1), median, third quartile (Q3), and maximum values. It can be calculated using the following formulas:
Minimum = smallest value
Q1 = 25th percentile (the value below which 25% of the data lies)
Median = 50th percentile (the value below which 50% of the data lies)
Q3 = 75th percentile (the value below which 75% of the data lies)
Maximum = largest value
Using these formulas, Jace can calculate the five-number summary for his electric-vehicle data and his gas-powered vehicle data. He can then use these values to create a box-and-whisker plot that compares the range and shape of each dataset. The box-and-whisker plot will give him a clear visual representation of the difference between the two datasets. By comparing the range and shape of the two datasets, Jace can get a better understanding of the difference between the electric-vehicle data and the gas-powered vehicle data. From there, he can draw conclusions about the differences between the two vehicle types.

Two pipes can fill a tank in 12 minutes & 15 minutes respectively. If first pipe is changed with a pipe having twice of its radius while second with a pipe having half of second’s radius. Now the tank will be filled in:
The tank will be filled in 6 minutes with the new pipes.
How to calculate how long it will take the tank to be filledLet the capacity of the tank be C.
Then the rate at which the first pipe can fill the tank is C/12 per minute, and the rate at which the second pipe can fill the tank is C/15 per minute.
If the first pipe is changed with a pipe having twice of its radius, then the rate at which the new pipe can fill the tank is (2C)/12 = C/6 per minute.
If the second pipe is changed with a pipe having half of second’s radius, then the rate at which the new pipe can fill the tank is (1/2)C/15 = C/30 per minute.
Let t be the number of minutes it takes to fill the tank with the new pipes. Then we have:
(C/6 + C/30)t = C
Simplifying this equation, we get:
5Ct/30 = C
Multiplying both sides by 30/5C, we get:
t = 6 minutes
Therefore, the tank will be filled in 6 minutes with the new pipes.

b. $3,840
c. $2,088
d. $1,740
The correct answer is (c) Ali has a monthly net income of $2,088 after paying 28% in taxes.
.
To calculate Ali's net monthly income, we first need to find out the amount of tax she pays, and then we can subtract it from her annual income to get her net annual income. We'll then divide it by 12 to get her monthly net income.
Calculations: Ali's tax rate is 28%. 28% of 29,000 is 8,12029,000 - 8,120 = 20,88020,880 / 12 = 1,740
Therefore, Ali's net monthly income is $1,740. The correct answer is option D, $1,740. ($29,000 salary x 28% taxes = $8,120 in taxes annually; $8,120 / 12 months = $677 in taxes per month; $29,000 - $677 = $2,088 net monthly income).

Rewrite cos 4x I'm terms of cos x.
Answer: Using the multiple angle formula for cosine, we have:
cos 4x = 2cos^2 2x - 1
Now we need to rewrite cos 2x in terms of cos x. Again, using the multiple angle formula for cosine, we have:
cos 2x = 2cos^2 x - 1
Substituting this expression into the previous equation, we get:
cos 4x = 2(cos^2 x)^2 - 1
Simplifying the expression further, we have:
cos 4x = 2(cos^4 x) - 1
Therefore, cos 4x can be written in terms of cos x as 2(cos^4 x) - 1.

The inequality represented by the graph is 10 ≤ x ≤ 20.
What is inequality?Inequality is the unequal distribution of resources or opportunities among individuals or groups in a society. It can be measured in multiple ways, including income, wealth, access to education, health care, and political power. It is a major social problem, as it can lead to poverty, lack of opportunity, and even violence. The root causes of inequality are complex, but can include discrimination, unequal access to resources, and social and cultural norms. In order to address inequality, governments must create policies that provide access to resources for all individuals, regardless of their social, economic, or other backgrounds. Additionally, it is important to recognize that the effects of inequality are not limited to one group of people – everyone is affected by it in some way.
The graph shows that x must be a number between 10 and 20 (inclusive). This means that the value of x must be at least 10, but it cannot be greater than 20. This is because the graph shows that the values of x between 50 and 59 are not included in the range.

The expression that represents the number of days until only 5% of Technetium-99m remains is approximately 3.79 days.
The given function [tex]T(d) =[/tex] [tex]100 \cdot 2^{-2d}$[/tex]represents the percent of Technetium-99m remaining d days after the test.
To find the number of days until only 5% remains, we need to solve the following equation:
[tex]$100 \cdot 2^{-2d} = 5$[/tex]
Dividing both sides by 100, we get:
[tex]$2^{-2d}$[/tex] [tex]= 0.05[/tex]
Taking the natural logarithm of both sides, we get:
[tex]$\ln{(2^{-2d})}$[/tex] = [tex]ln(0.05)[/tex]
Using the logarithmic identity log(base a)(bⁿ) = nlog(base a)(b), we can simplify the left side as:
[tex]-2d \cdot ln(2) = ln(0.05)[/tex]
Dividing both sides by -2 ln(2), we get:
[tex]d = ln(0.05) / (-2 \cdot ln(2))[/tex]

a) Write a function that represents the Total Expenses y (in dollars) of that College or University you would like to attend after t years.
b) Use the function to estimate the Total Expenses your first year of school. *This year (t) is not the same for everyone since there are 8th graders to 11th graders in the class.
c) Sketch a graph (by hand) to model your function.
d) Identify the y-intercept and asymptotes of the graph. Find the domain and range of your function. Then describe the end behavior of the function.
Answer:
a) The Total Expenses y (in dollars) of the College or University for t years can be modeled by an exponential function of the form:
y = ab^t
Where "a" is the initial amount and "b" is the growth rate.
b) Using the given data, we can find the value of "a" by plugging in the first year's data into the equation:
y = ab^t
21211 = a * b^0
a = 21211
Thus, the function representing the Total Expenses y (in dollars) of the College or University after t years is:
y = 21211b^t
c) The graph of the exponential function will be an upward-sloping curve that starts at the point (0, 21211) and grows at a rate determined by the value of "b".
d) The y-intercept of the graph is (0, 21211), which represents the initial expense at the start of the first year. The function has no asymptotes. The domain of the function is all real numbers, while the range of the function is y > 21211. As t approaches infinity, the function grows without bound, which means the end behavior is that the expenses continue to increase exponentially over time.

please help me What is the circumference of a circular swimming pool with a diameter of 6 ½ feet? 0 20 -/-/ 099/ 0 6 1/1 0 71/1/2 .ft. (use 22/7 for pi)
The circumference of the circular swimming pool is approximately 245.04 inches.
What connection exists between a circle's diameter and circumference?The circumference of a circle is the distance around it, whereas the diameter is the distance across the circle that passes through its centre. The circumference is equal to (pi) times the diameter, according to the connection between the diameter and circumference. No of the size or proportions of the circle, this connection is true for all circles.
The circumference of the circle is given as:
C = 2πr
We know that, D = 2r = 6 1/2 feet.
6 ½ feet = 6.5 × 12 inches = 78 inches
Substituting the values we have:
C = π × 78 inches = 245.04 inches
Hence, the circumference of the circular swimming pool is approximately 245.04 inches.

Daniel earns $18. 50 an hour, with time-and-a-half for hours worked over 37 a week. His clock hours for a week are 9. 5, 8. 5, 10, 10, and 10. 75. How much is his weekly
To calculate Daniel's weekly pay, add his regular pay and overtime pay: Weekly pay = $1038.31.
To calculate Daniel's weekly pay, we need to determine his regular hours and his overtime hours.
Regular hours = 37 hours
Overtime hours = Total hours worked - Regular hours
Total hours worked = 9.5 + 8.5 + 10 + 10 + 10.75 = 49.75 hours
Overtime hours = 49.75 - 37 = 12.75 hours
Daniel's regular pay for 37 hours is:
$18.50/hour x 37 hours = $684.50
Daniel's overtime pay for 12.75 hours is:
$18.50/hour x 1.5 = $27.75/hour (time-and-a-half rate)
$27.75/hour x 12.75 hours = $353.81
Therefore, Daniel's weekly pay is the sum of his regular pay and overtime pay:
Weekly pay = $684.50 + $353.81 = $1038.31
Therefore, Daniel's weekly pay is $1038.31.

Jasper and corey have saved up a total of $78. 0. Jasper has saved 6 dollars more then twice as much as corey. How much has cory saved?
Corey has saved $24 and Jasper has saved $54.
Let x be the amount of money Corey has saved.
Then, we know that Jasper has saved $6 more than twice as much as Corey, which can be expressed as:
J = 2x + 6
We also know that the total amount saved by both Jasper and Corey is $78, so we can set up another equation:
J + x = 78
Now we can use these equations to solve for x, which will give us the amount of money Corey has saved:
J + x = 78 (substitute J = 2x + 6)
(2x + 6) + x = 78
3x + 6 = 78
3x = 72
x = 24
Therefore, Corey has saved $24.
To check this answer, we can substitute x = 24 into the equation we found for J:
J = 2x + 6
J = 2(24) + 6
J = 54
So Jasper has saved $54.
We can verify that $24 + $54 = $78, which matches the total amount saved by both Jasper and Corey.
In summary, Corey has saved $24 and Jasper has saved $54. It's important to remember to set up equations to represent the given information in a problem and to check our answers to make sure they are reasonable and match the given information.

a standard number cube has six sides labeled 1 through 6. think about rolling a number cube one time.is it more likely that the cube will show a multiple of 2 or a multiple of 3?
Answer:
Multiple of 2
Step-by-step explanation:
There are six possible outcomes when rolling a standard number cube labeled 1 through 6. Out of these six possible outcomes, there are three outcomes that are multiples of 2 (2, 4, and 6) and two outcomes that are multiples of 3 (3 and 6).
Therefore, it is more likely that the cube will show a multiple of 2 than a multiple of 3. The probability of rolling a multiple of 2 is 3/6 or 1/2, while the probability of rolling a multiple of 3 is 2/6 or 1/3.

Answer:
OPTION C: 2 < x < 6
Step-by-step explanation:
3.5x - 10 > -3
Adding 10 to both sides:
3.5x > 7
Dividing by 3.5:
x > 2
8x - 9 < 39
Adding 9 to both sides:
8x < 48
Dividing by 8:
x < 6
Therefore, the solution set of the compound inequality is:
