In circle B, find x if m A = 3x + 9 and m B = 8x – 4.

Answers

2(3x + 9) = 8x - 4
6x + 18 = 8x - 4
22 = 2x
11 = x

The value of x is 11.

Central Angle Theorem :

It states that the central angle from two chosen points A and B on the circle is always twice the inscribed angle from those two points.

From given figure, [tex]A=3x+9,B=8x-4[/tex]

[tex]\angle B=2\angle A\\\\8x-4=2(3x+9)\\\\8x-4=6x+18\\\\8x-6x=18+4\\\\2x=22\\\\x=22/2=11[/tex]

5x+y=7
20x+2=y
What does x=?
What doesy=?

Answers

Answer: y = 6 x = 0.2

Step-by-step explanation:

5x+y=7

20x+2=y

re-write one

5x + y = 7 OR y = 7 - 5x

substitution

20x + 2 = 7 - 5x

20x + 5x = 7 - 2

25 x = 5

x = 5/25

x = 0.2

now for finding y

y = 7 - 5x

y = 7 - 5(0.2)

y = 7 - 1

y = 6

While on a business trip to Brookfield, Haley treated her co-workers to a meal that cost $50. Haley knew that when the bill came, she would need to pay Brookfield sales tax of 14% and would want to leave an 18% tip on the original $50. Including tax and tip, how much did Haley's meal cost?

Answers

Answer:

$66

Step-by-step explanation:

The meal cost $50 without taxes.

The cost of tax:

$50*%14= $7

so she will pay a $7 tax

Also, she wants to tip %18 of the original $50 so:

$50*%18= $9

so she will tip $9

$50 + $7 + $9 = $66

Plzz help me to find coefficient in binomial theorem (25 points)

Answers

Denote x2 by y.

(x2-3)7=(y-3)7

This is a binomial expansion in y, and you want the coefficient of y4 because y4=x8

You have 7 terms of (y-3) in (y-3)7. To get the fourth power of y, you need to choose y from four of the terms. The number of ways you can do this is the combinations of 7 things taken 4 at a time. This is:

7!/(4!3!)=35

So, the coefficient of x8 in the given expansion will be 210.

The vet told Casey that her dog should weigh at most 70 lbs. Her dog weighs 106 pounds, so Casey set a goal that he would lose 4 pounds per week. Which inequality represents the number of weeks it take for Casey's dog to reach 70 lbs?

Answers

Answer:

The inequality =

106 - 4x ≥ 70

The number of weeks =

9 weeks

Step-by-step explanation:

Let the number of weeks for Casey's dog to lose for 4 pounds be represented as: x

The goal weight = 70 Ibs

Hence:

70 Ibs = 106Ibs - 4Ibs ×x

106 - 4x ≥ 70

4x ≥ 106 - 70

4x ≥ 36

x ≥ 36/4

x ≥ 9 weeks

It would take 9 weeks for Casey's dog to lose 4 pounds per week and weigh 70 Ibs

Therefore:

The inequality =

106 - 4x ≥ 70

The number of weeks =

9 weeks

Given the statement "r varies jointly as s and t". if r =16 when s = 4 and t =6, what is the constant of the variation? I remember well the remark made to me once by one of my teachersand a very good teacher, too, who nevertheless did not see what her own observation ought to have suggested. School-children, she said, regard teachers as their natural enemies. The thought which it would have been logical to suppose would have followed this observation is, that if children in general are possessed of that notion, it is because there is a great deal in the teachers treatment of them which runs counter to the childs nature: that possibly this is so, not because of natural cussedness on the part of the child, but because of inapplicability of the knowledge taught, or the manner of teaching it, or both, to the mental and physical needs of the child. I am quite sure no such thought entered my teachers mind,at least regarding the system of knowledge to be imposed; being a sensible woman, she perhaps occasionally admitted to herself that she might make mistakes in applying the rules, but that the body of knowledge to be taught was indispensable, and must somehow be injected into childrens heads, under threat of punishment, if necessary, I am sure she never questioned. It did not occur to her any more than to most teachers, that the first business of an educator should be to find out what are the needs, aptitudes, and tendencies of children, before he or she attempts to outline a body of knowledge to be taught, or rules for teaching it. It does not occur to them that the childs question, What do I have to learn that for? is a perfectly legitimate question; and if the teacher cannot answer it to the childs satisfaction, something is wrong either with the thing taught, or with the teaching; either the thing taught is out of rapport with the childs age, or his natural tendencies, or his condition of development; or the method by which it is taught repels him, disgusts him, or at best fails to interest him.When a child says, I dont see why I have to know that; I cant remember it anyway, he is voicing a very reasonable protest. Of course, there are plenty of instances of wilful shirking, where a little effort can overcome the slackness of memory; but every teacher who is honest enough to reckon with himself knows he cannot give a sensible reason why things are to be taught which have so little to do with the childs life that to-morrow, or the day after examination, they will be forgotten; things which he himself could not remember were he not repeating them year in and year out, as a matter of his trade. And every teacher who has thought at all for himself about the essential nature of the young humanity he is dealing with, knows that six hours of daily herding and in-penning of young, active bodies and limbs, accompanied by the additional injunction that no feet are to be shuffled, no whispers exchanged, and no paper wads thrown, is a frightful violation of all the laws of young life. Any gardener who should attempt to raise healthy, beautiful, and fruitful plants by outraging all those plants instinctive wants and searchings, would meet as his rewardsickly plants, ugly plants, sterile plants, dead plants. He will not do it; he will watch very carefully to see whether they like much sunlight, or considerable shade, whether they thrive on much water or get drowned in it, whether they like sandy soil, or fat mucky soil; the plant itself will indicate to him when he is doing the right thing. And every gardener will watch for indications with great anxiety. If he finds the plant revolts against his experiments, he will desist at once, and try something else; if he finds it thrives, he will emphasize the particular treatment so long as it seems beneficial. But what he will surely not do, will be to prepare a certain area of ground all just alike, with equal chances of sun and amount of moisture in every part, and then plant everything together without discrimination,mighty close together!saying beforehand, If plants dont want to thrive on this, they ought to want to; and if they are stubborn about it, they must be made to.In the second sentence of the second paragraph, the repetition of the word things primarily serves toqualify a claim by acknowledging an exception to itAportray contrasting viewpoints as equally legitimateBclarify an argument by restating it in simpler termsCillustrate a generalization with a particular caseDstrengthen an assertion by broadening its implicationsE A pizza shop sells three sizes of pizza, and they track how often each size gets ordered along with how much they profit from each size.
