Step-by-step explanation:
He made 64 pots so?
2.77x64=177.28now since he made 3.19 selling all of them we have to multiply 64x3.19=204.16, now subtract this from how much it cost for him to make it.
He made 26.88$ in profit.
The table shows the cost for a clothing store to buy jeans and khakis. The total cost for Saturday's shipment, $1,800, is represented by the equation 15x + 20y = 1,800. Use the x- and y-intercepts to graph the equation. Then interpret the x- and y-intercepts.
The graph of the given function is attached below.
x intercept means if there will be no khakis shipped, then there will be 120 jeans shipped.
Also, y -intercept means if there will be no jeans shipped, then there will be 90 khakis shipped.
Given equation:-
15x + 20y = 1800
Where,
x represents the number of jeans shipped and,
y represents the number of khakis shipped
We have to use the x and y-intercepts to graph the equation.
Putting x = 0 to find the y -intercept, we get,
15(0) + 20y =1800
0 + 20y = 1800
y = 1800/20
y = 90
The coordinates of the point will be (0,90).
Putting y = 0 to find the x -intercept, we get,
15x + 20(0) =1800
15x + 0 = 1800
x = 1800/15
x = 120
The coordinates of the point will be (120,0).
Using the coordinates, we have graphed the graph attached.
Here, x intercept means if there will be no khakis shipped, then there will be 120 jeans shipped.
Also, y -intercept means if there will be no jeans shipped, then there will be 90 khakis shipped.

if you take away 25 from a number you will be left with two and halftimes 30. what is the number?
The following data was collected from a simple random sample from a process (infinite population).
13 15 14 16 12
I've already determined that the point estimate of the population mean is 14 and the point estimate of the population std. deviation is 1.581.
What is the Mean of the Population?
A. 14
B. 15
C. 15.1581
D. Could be any Value.
The mean of the population is 14, which is the point estimate of the population mean that was determined from the simple random sample.
The mean of the population is a measure of the central tendency of the population. It is calculated by taking the sum of all the values in the population and dividing by the total number of values. In this case, the mean of the population would be calculated by adding the values of the sample (13, 15, 14, 16, 12) and dividing by the total number of values (5). The mean of the population is then 14 (13 + 15 + 14 + 16 + 12 / 5 = 14).
To calculate the mean of the population, we first need to calculate the sum of all the values in the population. This is done by adding the values of the sample together (13 + 15 + 14 + 16 + 12 = 70). We then divide the sum of the values by the total number of values in the population (70 / 5 = 14). This gives us the mean of the population, which is 14.

What is a rotation?In Mathematics and Geometry, a rotation is a type of transformation which moves every point of the object through a number of degrees around a given point, which can either be clockwise or counterclockwise (anticlockwise) direction.
Next, we would apply a rotation of 90° clockwise about the origin to the coordinate of this triangle NOG in order to determine the coordinate of its image;
(x, y) → (y, -x)
Point N = (-4, -1) → Point N' (-1, 4)
Point O = (-4, -3) → Point O' (-3, 4)
Point G = (0, -1) → Point G' (-1, 0)

Window Rock Recruitment Agency just placed Alejandro Rivera in a job as an assistant
pharmacist. The job pays $71,500 annually. The agency fee is equal to 40% of the first
5 weeks' pay. Demonstrate and explain how you would be able to determine what he will
earn during the first 4 weeks if he pays the agency fee weekly?
Answer: To determine Alejandro's earnings for the first 4 weeks, we first need to calculate his weekly pay. To do this, we divide his annual salary by the number of weeks in a year:
Annual salary / 52 weeks/year = weekly pay
$71,500 / 52 weeks/year = $1,375/week
Next, we need to determine the agency fee that Alejandro will pay each week. The agency fee is equal to 40% of the first 5 weeks' pay, so we multiply Alejandro's weekly pay by 40% to get the agency fee:
Weekly pay * 40% = agency fee
$1,375/week * 40% = $550/week
Finally, to determine Alejandro's earnings for the first 4 weeks, we multiply his weekly earnings by the number of weeks:
Weekly pay * number of weeks = earnings
$1,375/week * 4 weeks = $5,500
So, Alejandro will earn $5,500 during the first 4 weeks of his new job, after paying the agency fee each week.

The amount of money in an account may increase due to rising stock prices and decrease due to falling stock prices. Maggie is studying the change in the amount of money in two accounts, A and B, over time.
The amount f(x), in dollars, in account A after x years is represented by the function below:
f(x) = 9,628(0.92)x
Part A: Is the amount of money in account A increasing or decreasing and by what percentage per year? Justify your answer.
Part B: The table below shows the amount g(r), in dollars, of money in account B after r years.
r (number of years) 1 2 3 4
g(r) (amount in dollars) 8,972 8,074.80 7,267.32 6,540.59
Which account recorded a greater percentage change in amount of money over the previous year? Justify your answer.
The amount of money in account A is decreasing by 8% per year.
The account that recorded a greater percentage change in amount of money over the previous year is account B.
How to calculate the percentage?From the information, the amount f(x), in dollars, in account A after x years is represented by the function below:
f(x) = 9,628(0.92)x
Therefore, this shows a decrease and the percentage will be:
= 1 - 0.92
= 0.08
= 8%
The account that recorded a greater percentage change will be:
Account B = (8,972 - 8,074.80) / 8,972 × 100
= 10%
Therefore, B has a higher percentage.

Answer:
+4
Step-by-step explanation:
F(x,y) = 3x+y and y <= -2x+ 4 sub in for 'y'
= 3x + (-2x+4)
= x + 4
If you look at the graph for y <= - 2x+4 ( see below)
you will see that the domain (x values ) can only go from 0 to 4 and the max value is +4 ( rememeber too that y is restricted to >= 0 as is x )

What is Perfect Square?A perfect Square is defined as an integer multiplied by itself to generate a perfect square, which is a positive integer. Perfect squares are just numbers that are the products of integers multiplied by themselves.
To complete the perfect square, we need to factor out the coefficient of the squared term (-2) from the expression:
A = -2x² + 36x
A = -2(x² - 18x)
Next, we need to add and subtract the square of half the coefficient of the x-term (-18/2 = -9) inside the parentheses:
A = -2(x² - 18x + (-9)² - (-9)²)
Simplifying the expression inside the parentheses, we get:
A = -2[(x - 9)² - 81]
Distributing the -2, we get:
A = -2(x - 9)² + 162
Therefore, the missing value in the expression is 162.

A bag contains 10 green,8 blue, and 2 white balls. Naomi seclets 2 balls from the bag at random, one at a time, without replacing them. What is the probability that she selects all two white balls?
E.) 2/95
F.) 1/95
G.) 1/190
H.) 1/380
To find the probability that Naomi selects both white balls, we need to consider the total number of possible outcomes and the number of favorable outcomes.
Total number of outcomes:
Naomi selects 2 balls without replacement, so the total number of outcomes is the number of ways she can choose 2 balls out of the total number of balls in the bag. This can be calculated using combinations:
Total outcomes = C(20, 2) = (20!)/(2!(20-2)!) = (20 * 19)/(2 * 1) = 190
Number of favorable outcomes:
Naomi needs to select 2 white balls. There are 2 white balls in the bag, so the number of favorable outcomes is the number of ways she can choose 2 white balls out of the 2 white balls in the bag:
Favorable outcomes = C(2, 2) = 1
Probability = Favorable outcomes / Total outcomes = 1/190
Therefore, the correct answer is (G) 1/190.
6 minus 3 times a number is less than 30. Find the number:
x > -8
Explanations:Let the number be represented by x:
Three times the number = 3x
Six minus three times the number = 6 - 3x
Six minus three times the number is less than 30:
That can be interpreted mathematically as:
6 - 3x < 30
To find the value of x:
Step 1: Collect like terms
- 3x < 30 - 6
-3x < 24
Step 2: Divide both sides by 3:
\(\frac{-3x}{3}=\text{ }\frac{24}{3}\)-x < 8
Multiply both sides by (-1) and change the < sign to >
(-1) (-x) > 8 x(-1)
x > -8

find the arc length?
The length of the Arc of the circle is 17.00 units
How to find the length of arc?We should know that the arc of the circle is part of the circumference of the circle cut off by the radii of the circle.
The length of the arc is given by
L=\(\frac{A}{360} *2*\pi *r\) where A= angle made by the radii
\(\pi\)=3.14, radius =10, L-length of arc = x
Applying the values in the formula we have
x=(x/3*2*3.14*10)÷360
Simplifying the expression
62.8x=1080x
Taking the ratio of both sides we have
62.8x:1080x
