x^2-7x+7y-y^2

Answers

Answer 1

Given: [tex] {x}^{2} - 7x + 7y - {y}^{2} [/tex]

Now factoring them,

[tex] = > (x - y)(x + y) - 7(x - y)[/tex]

[tex] = > (x - y)(x + y - 7)[/tex]

Therefore, the answer to the question is [tex] (x - y)(x + y - 7)[/tex]

What is the value of X

Answers

Answer:

The letter "x" is often used in algebra to mean a value that is not yet known.

Step-by-step explanation:

Answer:

x = 24

Step-by-step explanation:

∠ 13 and ∠ 14 are adjacent angles on a straight line and sum to 180° , then

4x + 11 + 3x + 1 = 180 , that is

7x + 12 = 180 ( subtract 12 from both sides )

7x = 168 ( divide both sides by 7 )

x = 24

Untuk gambar berikut hitunglah nilai A, B, C, dan D!

Answers

Answer:

Draw all the three triangles and label them.

First triangle perimeter is 20 + c + a

The second is (20+15) + 70 + (30+a)

Third is (20+35+12) + d + (a+30+b)

Now we need to find scale factor (s.f) from on triangle to the other.

35/20 = 1.75 s.f.

Thus, 70/1.75 = c and it's 40

Now use pythag to find a

A = square root of 20^2 + 40^2

=44.72

(a+30) = 74.72

47/35 = 1.34 s.f.

70/1.34 = d and it's 52.13

Now pythag again to find b

A = square root of 47^2 + 52.13^2

^2 = 70.19

So, a+30+ b = 70.19

40+30 + b = 70.19

b= 70-70.19

b= 0.19

A=40

B=0.19

C=40

D=52.13

Hope this helps!

Por qué crees que el valor de la media no aparece en la tabla y es un número decimal?

Answers

La media no aparece en la tabla ya que se requiere un calculo para encontrarla, además, es un número decimal pues corresponde a la suma de los resultados dividida en el número de días.

¿Qué es la media?

En matemáticas, la media o promedio corresponde a la suma de todos los valores dividida en el número total de valores. En este caso la media corresponde a la suma de las temperaturas dividida en el número de días.

Calcular la media:

Usando la formula anterior, calculemos la media:

16 + 19 +17 + 20 + 22 + 18 +15 = 127/7 = 18.7

El valor de la media es 18.7, al respecto se puede observar que:

Este valor no aparee en la tabla pues no corresponde a la temperatura de ningún día sino que debe ser calculado.Este valor es decimal, lo que se común al hallar la media ya que se suman todos los valores y se dividen por un número determinado.

A data set has a maximum of 84, a minimum of 34, a median of 52.5, an upper quartile of 64, and a lower quartile of 44. Which statement is true of the box plot of this data set? The box will go from 44 to 64.A line dividing the box will be at 54.The left whisker will go from 34 to 52.5.The right whisker will go from 44 to 84.

Answers

Answer:

The box will go from 44 to 64.

Step-by-step explanation:

A box plot shows the five-number summary of a set of data.

Given five-number summary:

Minimum = 34Lower quartile (Q₁) = 44Median (Q₂) = 52.5Upper quartile (Q₃) = 64Maximum = 84

To represent the given data as a box plot:

Draw a box from the lower quartile (44) to the upper quartile (64).Draw a vertical line through the box at the median (52.5).Draw horizontal lines (whiskers) from the lower quartile (44) to the minimum value (34) and from the upper quartile (64) to the maximum value (84).

(See attached for box plot).

Answers

The measure of the intercepted arc is: B. 84°.

The Inscribed Angle Theorem

Based on the inscribed angle theorem, if an inscribed angle measures A, and the intercepted arc measures B, therefore, A = 1/2(B).

Thus, given the following:

Inscribed angle = 42°intercepted arc = WV = ?

Thus:

42 = 1/2(WV)

WV = 2(42)

WV = 84°

Therefore, the measure of the intercepted arc is: B. 84°.

A local boy club sold 136 bags of mulch and made a total of $253 it sold two types of mulch hardwood for 2.00 a bag and pine bark for $1.75 a bag how many bags of each kind of mulch did he sell

Answers

Answer:

The total number of hardwood mulch is 48 and pine bark mulch is 128 and this can be determine by forming the linear equation in two variables.

Given :

A local boys club sold 176 bags of mulch and made a total of $520.

Sold two types of mulch : hardwood for $3.50 a bag and pine bark for $2.75 a bag.

Let the number of hardwood mulch be x and the number of pine bark mulch be y then the total number of mulch will be:

  --- (1)

And the total amount is given by the equation:

   ----  (2)

Substitute the value of y in equation (2).

y = 128

Now, put the value of y in equation (1).

x = 176 - 128

x = 48

So, the total number of hardwood mulch is 48 and pine bark mulch is 128

Your company is facing increasing levels of competition for major corporate customer accounts, and profits have declined significantly. You have tried everything you can to cut costs and remain competitive, with the exception of laying off employees. Your company has had a no-layoff policy for the past 20 years, and you believe it is an important part of the organizations culture. However, you are experiencing mounting pressure to increase your firms performance, and your no-layoff policy has been questioned by shareholders. Even though you havent decided whether to lay off employees and thus break with a 20-year tradition for your company, rumors are rampant in your organization that something is afoot, and employees are worried. You are meeting today to address this problem. Tasks to perform: 1. Develop a list of options and potential courses of action to address the heightened competition and decline in profitability that your company has been experiencing. 2. Choose your preferred course of action, and justify why you will take this route. 3. Describe how you will communicate your decision to employees. 4. If your preferred option involves a layoff, justify why. If it doesnt involve a layoff, explain why. Organizational culture comprises the shared set of beliefs, expectations, values, norms, and work routines that influence how members of an organization relate to one another and work together to achieve organizational goals. In essence, organizational culture reflects the distinctive ways in which organizational members perform their jobs and relate to others inside and outside the organization. It may, for example, be how customers in a particular hotel chain are treated from the time they are greeted at check-in until they leave; or it may be the shared work routines that research teams use to guide new product development. When organizational members share an intense commitment to cultural values, beliefs, and routines and use them to achieve their goals, a strong organizational culture exists. When organizational members are not strongly committed to a shared system of values, beliefs, and routines, organizational culture is weak. ///Tasks to perform: 1.
