Geometry help please. What is the value of v?

Answers

Answer:

v=15

Step-by-step explanation:

31+4v+44=9v

Answer:

v = 15

Step-by-step explanation:

By exterior angle theorem:

9v° = 31° + (4v + 44)°

9v° = (4v + 44 + 31)°

9v = 4v + 75

9v - 4v = 75

5v = 75

v = 75/5

v = 15

Ms. Albero decided to make juice to serve along with the pizza at the Student Government party. The directions said to mix 2 scoops of powdered drink mix with a half a gallon of water to make each pitcher of juice. One of Ms. Albero’s students said she will mix 8 scoops with 2 gallons of water to get 4 pitchers. How can you use the concept of proportion to decide whether the student is correct?

Answers

Answer:

2 scoops per pitcher,

Step-by-step explanation:

2 (per pitcher) * 4(pitchers) = 8

2 scoops makes 1 pitcher and she's using 8 scoops so that would give us 4 pitchers.

3x + 2 = 11

Answers

3x+2=11
(you need to isolate x, so step 1 is to subtract 2 from both sides.)
3x+2-2=11-2
3x=9
(then divide both sides by 3)
3x/3=9/3
x=3

Answer: x=3

Step-by-step explanation:

3x= 11-2

3x=9

Two numbers differ by 5. The sum of their squares is 193. Find the numbers.

Answers

Answer:

Let one number be x and the other be (x-5)

Step-by-step explanation:

x^2+(x-5)^2=193

x^2+x^2-10x+25=193

2x^2-10x+25=193

Subtract 193 from both sides of the equation.

2x^2-10x-168=0

x=12 or x=-7

what is the linear equation of (0.5,10) and -4.5,-10​

Answers

Answer:

The linear equation containing the points (0.5, 10) and (-4.5, -10) will be:

[tex]y=4x+8[/tex]

Please check the attached graph also.

Step-by-step explanation:

Given the points

(0.5, 10)(-4.5, -10)

Finding the slope between (0.5, 10) and (-4.5, -10)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(0.5,\:10\right),\:\left(x_2,\:y_2\right)=\left(-4.5,\:-10\right)[/tex]

[tex]m=\frac{-10-10}{-4.5-0.5}[/tex]

Refine

[tex]m=4[/tex]

Using the point-slope form of the line equation

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where

m is the slope of the line(x₁, y₁) is the point

substituting the values m = 4 and the point (0.5, 10)  in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 10 = 4(x-0.5)[/tex]

Add 10 to both sides

[tex]y-10+10=4\left(x-0.5\right)+10[/tex]

Simplify

[tex]y=4x+8[/tex]

Therefore, the linear equation containing the points (0.5, 10) and (-4.5, -10) will be:

[tex]y=4x+8[/tex]

2x^2 + 7x - 4 , i hope this helps

The equivalent expressions are:

x² + 11x + 18

2x² + 7x - 4

x² - 10x + 25

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

(x + 2) (x + 9)

(x + 4) (2x - 1)

(x - 5)²

Now,

Applying the distributive property.

1)

(x + 2) (x + 9)

x² + 9x + 2x + 18

x² + 11x + 18

2)

(x + 4) (2x - 1)

2x² - x + 8x - 4

Combining the like terms.

2x² + 7x - 4

3)

(x - 5)²

(x - 5) (x - 5)

x² - 5x - 5x + 25

x² - 10x + 25

Thus,

The equivalent expressions are:

x² + 11x + 18

2x² + 7x - 4

x² - 10x + 25

In a normally distributed data set with a mean of 24 and a standard deviation of 4.2, what percentage of the data would be between 19.8 and 28.2 and why

Answers

Answer:

By the Empirical Rule, 68% of the data would be between 19.8 and 28.2

Step-by-step explanation:

The Empirical Rule states that, for a normally distributed random variable:

68% of the measures are within 1 standard deviation of the mean.

95% of the measures are within 2 standard deviation of the mean.

99.7% of the measures are within 3 standard deviations of the mean.

In this problem, we have that:

Mean = 24

Standard deviation = 4.2

What percentage of the data would be between 19.8 and 28.2

19.8 = 24 - 4.2

28.2 = 24 + 4.2

So within one standard deviation of the mean

By the Empirical Rule, 68% of the data would be between 19.8 and 28.2

If you are describing to a friend something interesting that happened to you, you communicate not only with words but also with the tone and inflection of your voice, the look on your face, and the gestures you use. All of these forms of nonverbal communication help to explain what happened and to make it clear how you feel about it. A playwright knows that his audience not only will be able to hear the spoken script but also will be able to see characters and the setting. The writer of the short story does not have these advantages. The only means by which he can communicate with the reader and convey his ideas is diction. If he is to be published and remembered, he must use words skillfully.To write a story that will seem real to his readers, an author uses imagery. Imagery occurs when an author creates pictures with words. Using his imagination and skillfully manipulating the language, the author appeals to the reader's senses, making the reader feel, touch, taste, and hear. The most effective writers make use of the sound and rhythm of words and sentences to complement their meanings.Perhaps you have already noticed examples of imagery in stories you have read. A writer seldom uses a bland word in a description if a more specific word will create a clearer impression. Instead of walk, for instance, he is likely to say amble, shuffle, or swagger. Similarly, he avoids clichs such as "cold as ice" or "skinny as a rail." Instead, he strives for fresh, unique comparisons which give life to his writings. Often a writer uses the setting to complement the plot. Descriptions of buildings, weather, and scenery help to establish a mood and provide an appropriate background for the action.Read Esther 1:1-8 from the Holy Bible. This passage describes a great feast put on by King Xerxes.Now it came to pass in the days of Ahasuerus, (this is Ahasuerus which reigned, from India even unto Ethiopia, over an hundred and seven and twenty provinces:) That in those days, when the king Ahasuerus sat on the throne of his kingdom, which was in Shushan the palace, In the third year of his reign, he made a feast unto all his princes and his servants; the power of Persia and Media, the nobles and princes of the provinces, being before him: When he shewed the riches of his glorious kingdom and the honour of his excellent majesty many days, even an hundred and fourscore days. And when these days were expired, the king made a feast unto all the people that were present in Shushan the palace, both unto great and small, seven days, in the court of the garden of the king's palace; Where were white, green, and blue, hangings, fastened with cords of fine linen and purple to silver rings and pillars of marble: the beds were of gold and silver, upon a pavement of red, and blue, and white, and black, marble. And they gave them drink in vessels of gold, (the vessels being diverse one from another,) and royal wine in abundance, according to the state of the king. And the drinking was according to the law; none did compel: for so the king had appointed to all the officers of his house, that they should do according to every man's pleasure.
