Question: "What is the GCF of 30, 42, and 12?

You may ask, "How did you get the answer?"

1) Let's list out the factors of 30, 42, and 12.

30 - 1, 2, 3, 5, 6, 10, 15, 30

42 - 1, 2, 3, 6, 7, 14, 21, 42

What are the common numbers from the list?

1, 2, 3, 6

What is the greatest number from the list of the common numbers?

6

Now let's separate the variables and find the common factor of the variables.

Variables:  

w 2 ,  w 4 ,  w * w

can also be thought of as  w 1 .

Since  

w

is the lowest powered variable and all of the other ones are greater than that. Then it means that the common factor of the variables is  

w .

Respuesta:

x = 5.656854249

Explicación paso a paso:

[NOTA: Solo quería disculparme de antemano por cualquier mala gramática, ya que estoy usando un traductor para esto.]

x/Sen30°= 8/Sen45° [Multiplica ambos lados por Sen30°]

x = (8/Sen45°) * Sen30° [Resuelve usando una calculadora]

x = 5.656854249

After calculations, we find that the company saves a total of $12 x 160 = $1,920 per month by having Alex work instead of a paid employee.

In this scenario, the company has three unpaid interns, including P. Alex, who are working in exchange for college credit. This means that the company does not have to pay these interns any salary or wages.

If the company were to hire a paid employee instead of having an intern like Alex work, they would have to pay that employee $12 per hour for the work that needs to be done. This is the amount that the company would have to spend in wages for each hour worked by the employee.

Now, we know that Alex works for the full 8 hours per day, and for 20 workdays in a month. This means that she works a total of 8 x 20 = 160 hours in a month.

Therefore, the total amount of money the company would have to pay a paid employee for the same amount of work that Alex does would be $12 per hour x 160 hours = $1,920.

Since Alex is working for the company without any payment, the company saves the entire amount of $1,920 per month that they would have had to pay a paid employee to do the same work.

According to the solution we have come to find that, The interquartile range (IQR):

(3) 18.33

(4) 38.5

(5) 58.5

Interquartile range (IQR) is a measure of variability or spread of a dataset. It is the difference between the third quartile (Q3) and the first quartile (Q1) of a dataset. It shows the range of the middle 50% of the data. IQR is often used as a measure of spread because it is less sensitive to outliers than the range.

First, we need to find the median of the dataset. Since there are an even number of values, we take the average of the two middle values:

Median = (30 + 36) / 2 = 33

Next, we find the median of the lower half of the dataset (values less than or equal to the median):

Q1 = 1 + 28 + 30 / 3 = 19.67

And the median of the upper half of the dataset (values greater than or equal to the median):

Q3 = 38 + 40 + 36 / 3 = 38

Finally, we calculate the interquartile range (IQR):

IQR = Q3 - Q1 = 38 - 19.67 = 18.33

There are no outliers in this dataset.

First, we need to find the median of the dataset. Since there are an even number of values, we take the average of the two middle values:

Median = (50 + 52) / 2 = 51

Next, we find the median of the lower half of the dataset (values less than or equal to the median):

Q1 = 45 + 48 / 2 = 46.5

And the median of the upper half of the dataset (values greater than or equal to the median):

Q3 = 60 + 110 / 2 = 85

Finally, we calculate the interquartile range (IQR):

IQR = Q3 - Q1 = 85 - 46.5 = 38.5

There are no outliers in this dataset.

First, we need to find the median of the dataset. Since there are an even number of values, we take the average of the two middle values:

Median = (60 + 60) / 2 = 60

Next, we find the median of the lower half of the dataset (values less than or equal to the median):

Q1 = 17 + 68 / 2 = 42.5

And the median of the upper half of the dataset (values greater than or equal to the median):

Q3 = 72 + 130 / 2 = 101

Finally, we calculate the interquartile range (IQR):

IQR = Q3 - Q1 = 101 - 42.5 = 58.5

There is one outlier in this dataset, the value 130.

Answer:

$140.024

Step-by-step explanation:

We know

A TV that usually sells for $183.52 is on sale for 30% off.

183.52 x 0.7 = $128.464

So, $128.464 is the price of the TV on sale for 30% off, not including tax yet.

If the sales tax on the TV is 9%, what is the price of the TV, including tax?

9% = 0.09

128.464 x 0.09 = $11.56

Then we take

128.464 + 11.56 = $140.024

So, the price of the TV is $140.024

Answer:

68

Step-by-step explanation:

Let The first number = X

& the Second one = X + 16

Sum of these two numbers = 120

X + X + 16 = 120

2X = 120 - 16

2X = 104

X = 52

So , the first number = 52

& Second one = 52 + 16 = 68

Answer:

The numbers are 52 and 68.

Step-by-step explanation:

Let x be the first number and y be the second. The question tells us that:

1) x = y + 16

2) (x + y) / 2 = 60

2 equations, 2 unknowns. Solve the system. Plug equation 1 into equation 2:

(y + 16 + y) / 2 = 60

2y + 16 = 120

y + 8 = 60

y = 52

Now plug the value of y back into either original equation. I'll use the first:

x = 52 + 16

x = 68

The transformation that would produce an image with vertices B"(-2, 1), C"(3, 2), D"(0, -1) from the original vertices B(-3,0), C(2, -1), D(-1, 2) is the transformation (x,y) → (X + 1, y + 1).

By applying the transformation (x,y) → (X + 1, y + 1), each point's x-coordinate is shifted one unit to the right (X = x + 1), and each point's y-coordinate is shifted one unit upward (Y = y + 1). This results in the image with the given coordinates B"(-2, 1), C"(3, 2), D"(0, -1).

The other transformations listed do not match the given image coordinates and would not produce the desired result.

Answer:

(x, y) → (x, −y) → (x + 1, y + 1)

Step-by-step explanation:

Reflect the vertices over the x-axis by applying the transformation (x, y) → (x, -y):

B'(-3, 0) → B'(-3, 0)

C(2, -1) → C(2, 1)

D(-1, 2) → D(-1, -2)

Translate the reflected vertices by (1, 1):

B'(-3, 0) → B″(-3 + 1, 0 + 1) → B″(-2, 1)

C(2, 1) → C″(2 + 1, 1 + 1) → C″(3, 2)

D(-1, -2) → D″(-1 + 1, -2 + 1) → D″(0, -1)

So, the correct sequence of transformations is:

(x, y) → (x, -y) → (x + 1, y + 1)

===========================================

Work Shown:

AC/QS = BC/RS

4/10 = m/15

4*15 = 10*m

60 = 10m

10m = 60

m = 60/10

m = 6

The first equation is possible because the triangles are similar. The horizontal sides AC and QS form the ratio AC/QS. This is equal to the ratio of the diagonal sides BC/RS since similar triangles have their sides in proportion.

After the equation is set up, we cross multiply and then solve for m.

Step-by-step explanation:

The equation of the line is y = (1/8)x + 4. And the graph of the equation is drawn below.

A connection between a number of variables results in a linear model when a graph is displayed. The variable will have a degree of one.

The linear equation is given as,

y = mx + c

Where m is the slope of the line and c is the y-intercept of the line.

The slope of the line is 1/8. Then the equation of a line is written as,

y = (1/8)x + c

The line is passing through (0, 4), then we have

4 = (1/8) (0) + c

c = 4

The equation of the line is y = (1/8)x + 4. And the graph of the equation is drawn below.

Answer of given problem -2-3-(-4) is integer -1

The Latin term "Integer," which implies entire or whole, is where the word "integer" first appeared. Zero, positive numbers, and negative numbers make up the particular set of numbers known as integers.

Integer examples include: – 1, -12, 6, 15.

Symbol

The letter "Z" stands in for an integer.

Z= {……-8,-7,-6, -5, -4, -3, -2, -1, 0, 1, 2, 3, 4, 5, 6, 7, 8,……}

Several Integer Types

Three categories of integers exist:

-2-3-(-4)

Using BODMAS, solving the bracket value, we get

=-2-3+4

Now, subtracting 4 from -3, we get

=-2+1

Now subtracting 1 from -2

=-1

Hence, Answer of given problem -2-3-(-4) is integer -1.

solution: In picture.

The point(s) at which horizontal tangent(s) occur(s) are: (2, (-2 + √6) / 2) and (2, (-2 - √6) / 2).

2x - 4 = -4y² - 4y + 2 ------(1)

Differentiating equation (1) w.r.t x, we get:

2dx - 4 = [-8y - 4]dy/dx ------(2)

For horizontal tangent, dy/dx = 0.

Putting dy/dx = 0 in equation (2), we get:

2dx - 4 = -4(0) ------(3)

From equation (3), we get: 2x = 4 ⇒ x = 2.

Now, putting x = 2 in equation (1), we get:

4 = -4y² - 4y + 2 ⇒ 4y² + 4y - 2 = 0 ⇒ 2y² + 2y - 1 = 0.

Now, solving the above quadratic equation by quadratic formula, we get:y = (-2 ± √6) / 2.

Substituting this value in x = 2, we get two points:(2, (-2 + √6) / 2) and (2, (-2 - √6) / 2).

Therefore, the point(s) at which horizontal tangent(s) occur(s) are: (2, (-2 + √6) / 2) and (2, (-2 - √6) / 2).
