Solve For XX=..........................

Answers

Answer 1

Answer:

(3x -5)°+ (2x- 15)°=180°[sum of co- Interrior angles of a triangle is 180°]

or, 3x- 5 + 2x - 15=180°

or,5x - 20 = 180°

or, 5x = 180°+20

or, x = 200÷ 5

•°•x = 40°

Answer 2

Answer:

X = 40

Step-by-step explanation:

3x + 2x -5 -15 = 180

5x + -20 = 180

then u add 20 on both sides

5x + 0 = 200

ya the 0 is not necessary but I was showing u add 20 on both sides lol

then u divide 5 on both sides to get the x by itself

x = 40

Hope this helps dude ^-^

Find the measures of two supplementary angles if their measures are in the given ratio.
3:7

Answers

Two supplementary angles are in the ratio 3:7. Find the angles ?

Let the two angles be 3x and 7x.

Supplementary angles add up to 180 degrees.

Therefore:

3x + 7x = 180

10x = 180

x = 18

3x = 3 * 18 = 54

7x = 7 * 18 = 126

Measure of angles are 54° and 126°.

What is Supplementary angle?

Sum of two or more angles are 180 degrees then, the angles are called supplementary angle.

Given that;

The ratio of angles are 3 : 7.

Now,

Let the two angles be 3x and 7x.

Since, Supplementary angles are add up to 180 degrees.

So,

3x + 7x = 180

10x = 180

x = 18

So, First angle of supplemental angles = 3x

                                                           = 3 × 18  

                                                           = 54

And, Second angle of supplemental angles = 7x

                                                                   = 7 × 18

                                                                   = 126

Thus, Measure of angles are 54° and 126°.

Given f(x) = 4x − 6 and g(x) = f(2x),
write an equation for g.

g(x) = _______________________

Answers

Answer:

1 and 1/3

Step-by-step explanation:

Fx equals 4x-6

Add six to both sides

6 equals 4X

Divide both sides by 4

2/3 equals x

Then GX equals f (2x)

Two times 2/3 is 1 and 1/3

The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3

What is a function?

Function is a type of relation, or rule, that maps one input to specific single output.

We have been given that  f(x) = 4x − 6 and g(x) = f(2x), then;

We have to Add six to both sides;

f(x) = 4x − 6

6 = 4X

Now Divide both sides by 4;

2/3 =  x

Then G(X ) is equals to f (2x)

Now, 2( 2/3 ) =  1 /3

The value of g(x) when f(x) = 4x − 6 and g(x) = f(2x) will be; 1/3

Which of the following describes two triangles that are similar to one another?

Answers

We have to determine, which of the following triangle is similar to another one.

Two similar triangle are always congruent. Two figures are similar if they have the same shape and size.

Two triangles are similar if their corresponding sides are proportional. Two polygons are similar if their corresponding side are proportional.

If two angles and the included side of one triangle are equal to the corresponding angles and side of another triangle, the triangles are congruent.

Both triangles are similar by SSS theorem, because all three pairs are in proportion,

To calculate the proportion of sides,

Triangle 1; m1 = 67, m2 = 15

Triangle 2 ; m1 = 15 , m2 = 95

[tex]\dfrac{67}{15}= \dfrac{15}{95}[/tex]

Thus the angles are not proportion then the triangle are not similar.

Triangle 1; m1 = 24, m2 = 101

Triangle 2 ; m1 = 65, m2 = 101

[tex]\dfrac{24}{65}= \dfrac{101}{101}[/tex]

Thus the angles are not proportion then the triangle are not similar.

Triangle 1; m1 = 45, m2 = 80

Triangle 2 ; m1 = 59 , m2 = 45

[tex]\dfrac{45}{59}= \dfrac{80}{45}[/tex]

Thus the angles are not proportion then the triangle are not similar.

Triangle 1; m1 = 71, m2 = 32

Triangle 2 ; m1 = 71 , m2 =77

[tex]\dfrac{71}{71}= \dfrac{32}{77}[/tex]

Thus the angles are in same proportion then the triangle are similar.

What is the slope of this line? Enter your answer as a fraction in the simplest term in the box.

Answers

The slope is 2/-2, rise over run

Answer:

-1/1

Step-by-step explanation:

The slope of a line is always the rise over run where rise is up or down(y axis) and the run is side to side(x-axis). Then, if the line is going up, your answer will be negative. So, using the points given, you can tell that the line is moving 2 units down while also moving 2 units to the left. Another way to calculate this is y2-y1 over(/) x2-x1, the y equals your y coordinates, x equals your x coordinants,d the 1 and 2 represent which points. Whichever point you use, you have to use the same coordinants fr the same value. For example, if you took the points (-2,0) and (0,-2) and you used (0,-2) as your second value, you can enter those into the formula.

(-2)-(0) / (0)-(-2) = -2 / 2

the denominater is a possitive two because, when you subtract a negative number, that number becomes positive and you now add it due to the distributive property. 0-(1)(-2) = -2 x -1 = 2

Between which two years did the club see the greatest growth? By what percent did it grow?
A. The greatest growth was between years 3 and 4. The growth between those years was about 32%.
B. The greatest growth was between years 1 and 2. The growth between those years was about 5%.
C. The greatest growth was between years 3 and 4. The growth between those years was about 8%.
D. The greatest growth was between years 1 and 2. The growth between those years was about 36%.

Answers

Answer:

D

Step-by-step explanation:

19 - 14 = 5 / 14 x 100 = 35.714 > 36%

The other values by calculating the percent increase were

(from 2-3) = 31.57%

(from 3-4) = 32%

Greatest growth was between years 3 and 4. The growth between those years was about 32%.

What is Percentage?

percentage, a relative value indicating hundredth parts of any quantity.

Given table is  participation in a school's debate club during the last four years.

Year           1   2   3   4

Students   14 19 25 33

We need to find between which two years did the club see the greatest growth.

From year 1 and 2 the growth is increased by 5 (19-14)

year 2 and 3 the growth is increased by 6 (25-19)

year 3 and 4 the growth is increased by 8 (33-25)

So between 3 and 4 there is greatest growth.

Now let us find the percentage of the growth.

33-25/25

0.32×100

32%

Hence, greatest growth was between years 3 and 4. The growth between those years was about 32%.

Erskine Clarke.Which line from the story supports the idea that Fred is a courageous boy?It was Saturday afternoon when the boys of Wedderburn School went off as usual to swim their boats on a beautiful lake. Fred Langton had a new boat, which his grandfather had sent to him as a birthday present. It was a larger and better-constructed boat than any of the others. Each boy was, of course, eager that his own boat should win the race. Although all the boys admired Fred's boat and wished that they could have had one as good, they felt no grudge towards Fred himself. In fact, he was a general favorite in the school. He was kind-hearted, unselfish, and always willing to give anything that he had to his companions.I tell you, said Bill Cowan to his own particular chum, Joe Morris, that boat of Fred's will beat ours all hollow! I wish I had one as good!Well, suppose it does win, replied Joe Morris, I shall not grudge it to him, for Fred is no sneak; he is out-and-out the jolliest fellow in Wedderburn School.So he is, said Bill Cowan, and no mistake about it. Well, here we are at the lake, and now for some fun.On this particular Saturday, however, Fred was going to become famous in quite another way. The little boats were all in full sail, and the schoolboys were shouting with glee at the fun. Suddenly a fox-terrier took it into his head to chase the boats and show that he could swim as well as they could. Poor dog! It was quite true that he could swim. Unfortunately he got caught among weeds. He began struggling in the water and barking for help.Oh, I say, I can't stand this! cried Fred Langton; he will be drowned. I must go in and fetch him out!No, no! cried Bill Cowan; the lake is quite deep just at that place.Yes, I know it's deep, added Joe Morris, and, besides, you can't swim, Fred; don't be silly. Who cares for a dog being drowned?I do, for one, cried Fred, and dashing into the water he waded out to where the poor dog was half-standing, half-lying, among the choking weeds. Yes, the water was deep; but stretching out his arms he contrived to catch hold of the poor animal, and he quickly waded back to shore amid ringing cheers from all the people who had now gathered on the bank to watch the plucky lad. And whose was the dog? Nobody knew; it seemed, indeed, to have no owner and no home. But Fred and his companions carried it back with them to the school, and, after having told their tale, they begged the head master to keep it for himself. As Dr. Williams could not discover anything about the dog's ownership, he did keep it. So Fred's brave deed not only saved the animal's life, but procured a good home for it as well. what of the following are functions of lipids? choose three correct answers derive ideal gas equation for n mole of gas. which one of these situations is commonly caused by acid rain?a. people being poisoned by drinking water b. fish and birds in freshwater habitats dying offc. people receiving acid burns on there skind. whales and dolphins dying off in the oceans What value of x makes this equation true?need done fast please, offering 25 points!

Founded in 1983 by Nicolas Hayek, Swatch is now the worlds biggest watch maker. The company not only produces finished watches, it also produces jewelry, watch movements, and watch components. Indeed, Swatch Group supplies nearly everything used in the production of its 18 individual brands that includes icons like Omega and Harry Winston as well as more mainstream options like Tissot and Longines. In addition to its own line of products, Swatch Group sells watch components to third-party watchmakers and produces parts used for sport event timing. Swatch employs about 37,000 people across 37 global subsidiaries. With some 40 percent of the company still under the control of the Hayek family, Swatch focuses on diversity and culture. The Swatch Revolution combines Swiss excellence in watchmaking with quirky affordable plastic components. Swatch promotes its watches as a means of speaking without words. Wearers of Swatch watches are telling more than just time, they are telling the world something about themselves. Swatch even suggests that wearers share their individuality and preferences on Instagram by tagging #MySwatch. Discussion Questions 1. With the Hayek family controlling nearly 40 percent of The Swatch Group, how do you think the familys influence impacts the corporate culture in the company? What about the companys international culture being impacted by the Hayek family? 2. Many of the Swatch brands have become cultural icons among a strong core following of customers in the global marketplace. Some even talk about the "Swatch Revolution" that began when Nicolas Hayek founded the company. Why do you think Swatch has such a strong cultural following? 3. As mentioned, Swatch wants you to create your own unique way of accessorizing through its Swatch watch. Is a watch a way to show who a person is culturally? Does a watch get embedded into a persons culture? Can a watch create a cultural image?
