Answer:

∠A = 44°

Step-by-step explanation:

In order to find the measure of angle A, you need to know the value of the variable x. This means you need some relation that you can solve to find x.

Happily, that relation is "the sum of angles in a triangle is 180°." This means ...

84° +(x +59)° +(x +51)° = 180°

(2x + 194)° = 180° . . . collect terms

2x = -14 . . . . . . . . . . divide by °, and subtract 194

x = -7 . . . . . . . . . . . .divide by 2

Now, the measure of angle A is ...

∠A = (x +51)° = (-7 +51)°

∠A = 44°

What common ratio would cause a geometric series to converge

Answers

Answer:0

Step-by-step explanation:

The sum of a convergent geometric series can be calculated with the formula a ⁄ 1 – r, where “a” is the first term in the series and “r” is the number getting raised to a power. A geometric series converges if the r-value (i.e. the number getting raised to a power) is between -1 and 1. So the answer is 0

Identify the unit rate in the graph.
A. 40mph
B. 75mph
C. 50mph
D. 25mph

Answers

Answer:

The unit rate is C. 50mph

Step-by-step explanation:

Take two points from the line,

I took points (1, 50) and (2, 100).

Then plug them into this formula:

y2-y1/x2-x1

Solve:

(100- 50)/(2 - 1)

100 - 50 = 50

2 - 1 = 1

50/1 = 50

So, you get C. 50mph

in the similarity transformation of abc to def, abc was dilated by a scale factor of [?], reflected across the [ ], and moved through the translation [ ].

Answers

The complete similarity transformation is: triangle abc was dilated by a scale factor of [2], reflected across the [x-axis], and moved through the translation [0].

How to complete the similarity statement?

From the figure, we have:

AB = 2 units

DE = 4 units

So, the scale factor (k) is:

k = DE/AB

k = 4/2

k = 2

So, the scale factor is 2

Also, both shapes are on either sides of the x-axis, and they are equidistant from the x-axis.

This means that the triangle is reflected across the x-axis with no translation.

Hence, the complete similarity transformation is:

abc was dilated by a scale factor of [2], reflected across the [x-axis], and moved through the translation [0].

The value of y varies directly with x. If x = 195 when y = 15, what is the value of x when y = 9?

Answers

Since the value of y varies directly with x, the value of x when y equals 9 is [tex]\frac{9}{13}[/tex]

Given the following data:

x = 195y = 15

To find the value of x when y = 9:

This is a direction proportion exercise and you're required to solve for the value of x when the value of y is equal to 9.

First of all, we would determine the constant of proportionality (k) for the mathematical expression.

[tex]y = kx\\\\15 = 195k\\\\k = \frac{195}{15}[/tex]

k = 13

Now, we can find x:

[tex]y = kx\\\\9 = 13x\\\\x = \frac{9}{13}[/tex]

Therefore, the value of x when y equals 9 is [tex]\frac{9}{13}[/tex]

Nine times the sum of nine and a number is -25. What is the number

Answers

Answer:

9(9 + x) = -25

x = 6.22222 repeating

Step-by-step explanation:

First, we have to distribute. 9 times 9 = 81 and 9 times x = 9x. The equation now becomes 81 + 9x = -25.

Second, we have to get the coefficient alone. Since the opposite of positive 81 is negative 81, we subtract it to get 0. Since we did that to one side we have to do it to the other. -25 - (-81) = 56. Now we have 9x = 56.

Third, we have to get the variable by itself. To do that we divide 9 by 9 to get 0 and that gets the variable alone. Since we did that to one side we have to do it to the other. 56 divided by 9 = 6.222 with the 2 repeating over 8 times.

Estimate 25.65 + 13.23 + 6.35 by rounding each number to the nearest tenth.

a. 26 + 13 + 6 = 45

b. 25.7 + 13.2 + 6.4 = 45.3

c. 25.6 + 13.2 + 6.3 = 45.1

d. 25.7 + 13.3 + 6.4 = 45.4

Answers

Answer:

b. 25.7 + 13.2 + 6.4 = 45.3

Step-by-step explanation:

25.65 ≈ 25.7, 13.23 ≈ 13.2, 6.35 ≈ 6.4

25.65 + 13.23 + 6.35 =25.7 + 13.2 + 6.4 = 45.3

Given the graph of a proportional relationship, if the (2,7) lies on the graph, what is the value of k? What is the equation of the line?

Answers

Answer:

k=3.5, and y=3.5x is the equation of the line

Step-by-step explanation:

y and x are proportional means that y = kx for some constant k.

Thus, when y=7 and x=2, we have that 7 = k * 2, so that k = 7/2 = 3.5,

and the equation of the line is y = 3.5x

Which group of words does the author use to advance the plot through the characters?from Sense and Sensibility CHAPTER IVby Jane Austen "What a pity it is, Elinor," said Marianne, "that Edward should have no taste for drawing." "No taste for drawing!" replied Elinor, "why should you think so? He does not draw himself, indeed, but he has great pleasure in seeing the performances of other people, and I assure you he is by no means deficient in natural taste, though he has not had opportunities of improving it. Had he ever been in the way of learning, I think he would have drawn very well. He distrusts his own judgment in such matters so much, that he is always unwilling to give his opinion on any picture; but he has an innate propriety and simplicity of taste, which in general direct him perfectly right." Marianne was afraid of offending, and said no more on the subject; but the kind of approbation which Elinor described as excited in him by the drawings of other people, was very far from that rapturous delight, which, in her opinion, could alone be called taste. Yet, though smiling within herself at the mistake, she honoured her sister for that blind partiality to Edward which produced it. "I hope, Marianne," continued Elinor, "you do not consider him as deficient in general taste. Indeed, I think I may say that you cannot, for your behaviour to him is perfectly cordial, and if that were your opinion, I am sure you could never be civil to him." Marianne hardly knew what to say. She would not wound the feelings of her sister on any account, and yet to say what she did not believe was impossible. At length she replied: "Do not be offended, Elinor, if my praise of him is not in every thing equal to your sense of his merits. I have not had so many opportunities of estimating the minuter propensities of his mind, his inclinations and tastes, as you have; but I have the highest opinion in the world of his goodness and sense. I think him every thing that is worthy and amiable." "I am sure," replied Elinor, with a smile, "that his dearest friends could not be dissatisfied with such commendation as that and I do not perceive how you could express yourself more warmly." Marianne was rejoiced to find her sister so easily pleased. "Of his sense and his goodness," continued Elinor, "no one can, I think, be in doubt, who has seen him often enough to engage him in unreserved conversation. The excellence of his understanding and his principles can be concealed only by that shyness which too often keeps him silent and you know enough of him to do justice to his solid worth. But of his minuter propensities, as you call them you have from peculiar circumstances been kept more ignorant than myself. He and I have been at times thrown a good deal together, while you have been wholly engrossed on the most affectionate principle by my mother and I have seen a great deal of him, have studied his sentiments and heard his opinion on subjects of literature and taste; and, upon the whole, I venture to pronounce that his mind is well-informed, enjoyment of books exceedingly great, his imagination lively, his observation just and correct, and his taste delicate and pure. His abilities in every respect improve as much upon acquaintance as his manners and person. At first sight, his address is certainly not striking; and his person can hardly be called handsome, till the expression of his eyes, which are uncommonly good, and the general sweetness of his countenance, is perceived. At present, I know him so well, that I think him really handsome; or at least, almost so. What say you, Marianne?" "I shall very soon think him handsome, Elinor, if I do not now. When you tell me to love him as a brother, I shall no more see imperfection in his face, than I now do in his heart." what is the rule for the reflection On Manifest Destiny, by John L.
