7. Solve For X:8. Find M

Answers

Answer 1

Answer:

From Triangles...

The sum of two opposite interior angles = the exterior

so

3x-2 + 9x + 7 = 14x - 19

12x +5=14x -19

Collecting Like terms

2x= 24

x= 12°.

For "m"

Sum of angles in a triangle=180°

So

180 - (19x-3+9x-2) = m

180 -(28x -5) =m

m= 180 - 28x + 5

m=185 - 28x.

Now

Since sum of everything in a triangle = 180

185 - 28x + 9x -2 + 19x - 3 = 180

185 -28x + 28x -5= 180

185-5=180

180=180

3- Option 3

4- 108 degrees

Answer:

1. C

2. B

3. Option 3

4. 108 degrees

Step-by-step explanation:

1. There cannot be less than 0 people or more then 25 people, but the theatre capacity can be equal to both of these numbers.

2. x is multiplied by 8 to create y, so the equation is y=8x

3. There can't be over 8 refrigerators on the truck, and you can't have a fraction of a refrigerator.

4. One line is 180 degrees. 36+36=72, 180-72= 108 degrees

In an arithmetic sequence, the 10th term is 37, and the 21st term is 4. Find the common difference and the first term

Answers

Answer:

Common difference is 3. And the first term is 64.

Step-by-step explanation:

The differnce between 21 and 10 is 11. So there are 11 unknown numbers in between.  And the difference between 37 and 4 is 33. 33/11 is equal to 3. So the pattern is minus three. the first term is 9 terms before 37. 9 times 3 is 27. 37+27 is equal to 64. so the first term is 64

The triangle below is equilateral. Find the length of side x in simplest radical form with a rational denominator.

Answers

Answer:

x = 8

Step-by-step explanation:

If a triangle is equilateral, each vertex has an angle that is equal to 60 degrees

As we can see, we have two sets of similar right triangles

The value x faces the right angle and that makes it the hypotenuse

Also, the side measure 4 is the adjacent side to the angle 60

The trigonometric identity that relates the hypotenuse and the adjacent is the cosine

it is the ratio of the adjacent to the hypotenuse

Mathematically;

cos 60 = 4/x

x = 4/cos 60

x = 8

3x-8y=24
y=x-8
Please show
work

Answers

Answer:

3x - 8y = 24   --------(1)

y = x - 8  ---------(2)

substitute  y in (1)

3x - 8( x - 8) = 24

3x - 8x + 64 = 24

-5x = 24 - 64

-5x = -40

5x = 40

x= 8

substitute x in (2)

y = 2 - 8

y = - 6

Answer:

x = 8, and y = 0

Step-by-step explanation:

We can solve this by taking y as (x-8), as it states there.

Since y is equal to x-8, we can rearrange the system of equations into one single equation.

We can multiply y by 8, as it shows in the first equation, which is something like 8x-64.

Since it is a negative 8 being multiplied by y, it would be the inverse of 8x-64, which is -8x+64.

We can now organize our equation here.

3x - 8x + 64 = 24.

We can use subtraction property of equality by subtracing 64 from both sides to get rid of it.

We will get something like:

3x - 8x + 64 - 64 = 24 - 64.

Simplify by solving like terms like the x value and the integers.

-5x = -40

Divide both sides with division property of equality:

-5/5x = -40/5

x = 8

We can then plug the 8 back into x, lets use the second equation because I'm lazy and it looks the easiest to solve for.

y = (8) - 8

y = 0

Therefore, x = 8, and y = 0.

A bag contains n counters. one counter is blue and the rest are red. Two counters are taken at random from the bag. a) express, in terms of n, the probability that a counter of each colour is taken. Give your answer as a fraction. b) the probability that a counter of each colour is taken is 0.125. How many red counters are in the bag?

Answers

Answer:

A] Probability = 1/n ; B] Number = 8

Step-by-step explanation:

Total counters = n , Blue counter = 1 , Red counters (remaining) = n -1

A] Prob (One blue, & One red counter) = (Blue counter / Total counters) x (Red counters / Total remaining counters) = [1 / n] x [ (n -1) / (n-1)] = 1 / n

Alternative, Prob  (One red, & one blue) = (Red counter / Total counters) x (Blue counters / remaining counters) = [ (n-1) / n ] x [1 / (n-1) ]  = 1 / n

B] Prob (each color , a blue & red counter taken) = 0.125  {Given}

By A], this Prob = 1/n.

So, 0.125 = 1/n → n = 1 / 0.125 = 8

A volume of the cone is (1/3) the volume of a cylinder. The volume of the sphere is what fraction of the volume of the cylinder?

Answers

Answer:

4/3

Step-by-step explanation:

To know this, let's write down the formulas for the volume of cylinder and sphere.

Vs = 4/3πr³   (1)

Vc = π r² h    (2)

Now, we do have a little problem here and its the fact that the sphere do not have a height like the cylinder do. But in this case so if you want to have an idea of the fraction of the volume, we will assume that the cylinder has the same height as its radius. Assuming this we have the following:

Vs / Vc = 4πr³ / 3πr²h

Vs/Vc = 4πr³ / 3πr³

From here, we can cancel out the values of π and r³:

Vs/Vc = 4/3

Vs = 4/3 Vc

Thus we can conclude that the volume of the sphere is 4/3 the volume of a cylinder.

The Kings HawkA Even the worlds greatest leaders sometimes learn things the hard way. Eight hundred years ago a powerful king named Genghis Khan ruled an empire that stretched from eastern Europe to the Sea of Japan and included all of China. His armies marched on China and Persia, and Khan was known as the greatest king since Alexander the Great.B According to legend, one day Khan gathered some friends and servants and rode into the countryside to search for game. Everyone in the party had high hopes of bringing home enough meat for a great feast that night. In those days it was customary to bring a trained hawk along on hunting trips. On command, the hawk would leave its masters wrist and fly high into the sky. Then, using its exceptional eyesight, the hawk would spot its prey and swoop down on it, so the hunters would know where to follow.C On this trip the king had brought his favorite hawk. It was a hot summer day, and although the hunting party rode for hours, they had no luck finding game. At dusk they gave up and turned toward home. The king knew the area well, and while the hunting party took the fastest way home, the king rode off on his own between two large mountains, determined to have a successful hunt. In the valley, his hawk flew off.D As the king rode farther, he became parched and started looking for a spring of water. His thirst was growing, but the hot summer had dried up all the brooks that usually ran by the path. Finally, he spotted a trickle of water running over the edge of a steep rock. Quickly, he jumped from his horse, taking a small silver cup from his bag. He held the cup under the trickle of water until there was enough to drink.E However, as he raised the cup to his lips, there was a whooshing sound, and the cup was knocked from his hand to the ground. The king turned to see who could be responsible. Spotting his pet hawk, he wondered why the bird would do such a thing. Angrily, the king picked up the cup and again held it under the trickling water. This time he held the cup for just a few seconds before he began to raise it to his mouth. Just as the cup touched his lips, the hawk flew down again, rushed past the king, and again knocked the cup to the ground.F The king was very angry now. Again he filled the cup, and again the hawk kept him from having even the smallest drink. You awful bird! the king shouted. If you were near me I would kill you in an instant! As the king filled the cup for the fourth time, he spoke to the hawk. Now, you arrogant hawk, I warn you. If you value your life, let me drink. As he spoke, he held his sword ready. Again the bird flew down, knocking the cup from the kings hand; but this time, the king was ready. His sword flashed and the bird fell. The hawk dropped at his masters feet and died quickly.G That will teach you, said the king. Then Genghis Khan turned and looked for the cup, but it was nowhere to be found. I will drink now anyway, he said, and started climbing the steep rock toward the source of the water. It was a long climb, and the kings thirst grew and grew.H Finally, he reached the top and could see the water. As he walked closer, he could see something in the water. With one more step the king could see now that the huge thing was a dead snake, one of the most poisonous in his entire kingdom.I Now, the king stopped walking. He forgot his thirst, and his heart ached as he thought dismally of the dead hawk he had left lying on the ground below. He dropped his head and said, You were a true friend, Sir Hawk. You saved my life, and yet in anger I killed you. I will honor your memory and never forget the lesson you taught me.In paragraph A, the author most likely compares the king with Alexander the Great inorder to show that the kingA. was enormously powerfulB. hoped to become famousC. came from noble blood linesD. was humble despite his high position
