Answer 1

Answer:

x = 14

∠ABD = 66

∠DBC = 24

Step-by-step explanation:

The sum of the two angles is 90 degrees, so:

3 (x + 8) + 2x - 4 = 90 (distribute 3)

3x + 24 + 2x - 4 = 90 (simplify)

5x + 20 = 90 (subtract 20 from both sides)

5x = 70 (divide both sides by 5)

x = 14

∠ABD = 3 (x + 8) (plug in 14)

∠ABD = 3 (14 + 8) simplify

∠ABD = 3 (22)

∠ABD = 66

∠DBC = 2x - 4 (plug in 14)

∠DBC = 2(14) - 4 (simplify)

∠DBC = 28 - 4

∠DBC = 24

To check, 66+24=90.

Answer 2

Answer:

The answer I got was

3(-26+8) = -54

2(-26)-4 = -56

Step-by-step explanation:

3(x+8)=2x−4

(3)(x)+(3)(8)=2x+−4(Distribute)

3x+24=2x+−4

3x+24=2x−4

Then subtract 2x from each side

Once then you have X substitute that number with X and you should get your answer.

So do 3(-26+8) and then 2(-26)-4 which then

3(-26+8)=

2(-26)-4 =

Here are three intersecting lines. Write an equation that represents a relationship between these angles. Describe, in words, the process you would use to find .

Answers

Answer:

[tex]w = 52[/tex]

Step-by-step explanation:

Given

See attachment for intersecting lines

Required

Find w

Using the horizontal line as a point of reference, the blank angle between w and 76 equals w.

This is so because it corresponds to angle w, at the bottom of the horizontal line.

So, to find w, we make use of:

[tex]w + w + 76 = 180[/tex] --- angle on a straight line

Collect like terms

[tex]w + w = -76 + 180[/tex]

[tex]2w = 104[/tex]

Solve for w

[tex]w = \frac{104}{2}[/tex]

[tex]w = 52[/tex]

Answers

Answer:

The first one (highlighted one)

Step-by-step explanation:

The answer is the one selected. When multiplying and subtracting numbers, you do the combination that is multiplying before you subtract-unless there are numbers in parenthese. You work parentheses first. In all of the other options, you are multiplying first so not subtracting from 3. For example the second option, you would multiply 4x7 BEFORE you subtract from 3 which doesn’t work. You are also multiplying first in options 3 and 4.

3. Suppose the radius of the larger circle is r. What is its diameter?
d2 =
R2

Answers

Answer:

Step-by-step explanation:

You suppose that the radius of a larger circle = r

so diameter = r*2 = 2r

aint really sure tho

Answer:

Step-by-step explanation:

The formula to find the diameter states the relationship between the diameter and the radius. The diameter is made up of two segments that are each a radius. Therefore, the formula is: Diameter = 2 * the measurement of the radius. You can abbreviate this formula as d=2r.

What is the gradient of the line that passes through the points (0,0) and (3,3)?

Answers

Answer:

Step-by-step explanation:

the gradient is a value that indicates how much the x value increases as the y value increases. It can be written as

rise/run

change in y value/change in x value

(y1-y2)/(x1-x2), where we know two coordinates (x1,y1) and (x2,y2).

We have two coordinates (0,0) and (3,3)

Therefore,

x1 = 0, y1 = 0

x2 = 3, y2 = 3

If we plug these values into the formula, it is [tex]\frac{3-0}{3-0} = \frac{3}{3} = 1[/tex]

Answer:

99.7% of customers have to wait between 8 minutes to 30 minutes for their food.

Step-by-step explanation:

We are given the following in the question:

Mean, μ = 18 minutes

Standard Deviation, σ = 3 minutes

We are given that the distribution of amount of time is a bell shaped distribution that is a normal distribution.

Empirical Formula:

Almost all the data lies within three standard deviation from the mean for a normally distributed data.

About 68% of data lies within one standard deviation from the mean.

About 95% of data lies within two standard deviations of the mean.

About 99.7% of data lies within three standard deviation of the mean.

Thus, 99.7% of the customers have to wait:

Thus, 99.7% of customers have to wait between 8 minutes to 30 minutes for their food.

Answers

Answer:

92 is your answer

Step-by-step explanation:

we have

3x/4-1=x/2+7 side of square are equal

3x/4-x/2=7+1

(3x-2x)/4=8

x=8×4=32

length =3×32/4 -1=24-1=23

now

perimeter=4×length=4×23=92 units

Answer: The perimeter of the square is 92 units.

Step-by-step explanation:

All four sides of a square are equal. Set the given values 3/4x - 1 and 1/2x + 7 equal to one another. It should like this: 3/4x - 1 = 1/2x+7. The next step is solving for x. We get x = 32 as our answer. See the image of the work below if you are confused. :) Next, plug in this answer to the original equations: 3/4x-1 and 1/2x+7.

3/4(32) - 1 = 23

1/2(32) + 7 = 23

After basic substitution, we will conclude that each side of the square is 23 units long. To find perimeter use the equation 4s (let s represent sides). 4(23) = 92 units. Hope this was helpful!

What is m∠1? Help me, please

Answers

Answer:

∠1 = 72°

Step-by-step explanation:

exterior ∠ = the sum of two opposite(remote) interior ∠s

∠1 = 37° + 35°

=> ∠1 = 72°

Answer:

72 degrees.

Step-by-step explanation:

Angle 1 is one of the triangle's exterior angles. The exterior angle theorem states that the measure of a triangle's exterior angle is equal to the sum of the opposite interior angles. Therefore, m<1 is equal to the sum of 35 and 37:

35+37=72

m<1 = 72 degrees

It was empty, so Odysseus suggested that they wait for its owner to return, hoping for a hospitable inhabitant. The soldiers advised against this, but Odysseus insisted. Not long after, they discovered that their host was the quite inhospitable Cyclops, who proceeded to trap them in the cave by blocking the entrance with an enormous rock. Many of Odysseuss men had suggested ending the beasts life, but that would leave them trapped in the cave. Even if they all worked together, they would not have the strength to remove the boulder from the caves opening. For the past few days, Odysseus had observed the one-eyed monster. He had noticed that every morning, the Cyclops removed the rock from the caves opening to let out his flock of sheep before replacing it to keep Odysseus and his men confined inside. "We will blind the monster. Then, well use his own sheep to aid us in our escape, Odysseus explained to his crew. I have noticed that the males are fully grown and have thick black wool. We can tie three of them together. Then, we can hide a man under the belly of the middle animal. This way, hell be able to pass by the Cyclops unnoticed. Once the monster had fallen asleep, Odysseus blinded the Cyclops. The beast cried out in pain but then drifted back into slumber as the soldiers had shared their strong mead with him that night. Odysseus and the men worked all night to make sure there were three sheep for each man. Once his crew was hidden, Odysseus leapt onto the remaining sheepa ram that was finer than all the others. Then, he wiggled his way underneath the animal, concealing himself in the dark wool hanging below the rams belly. As dawn approached, the men were fearful that the plan would not succeed, but they knew they must carry on if they hoped to escape the Cyclopss lair. When the sun rose above the horizon, the Cyclops awoke and opened the cave entrance for his flock. Despite his pain, the Cyclops felt the back of each animal as it stood up and left the cave. He was not aware that the men were hidden beneath their bellies.As the last sheep went out, the fine ram concealing Odysseus, the Cyclops grabbed hold of the animal. My good ram, why are you last today? You never let the others go ahead of you, the Cyclops mused aloud. Youre usually the one leading the restwhether it is to go out and eat in the morning, or it is to come home at night. Odysseus held his breath; would they be discovered? But to his relief, the monster let the ram go out to the pasture with the other sheep. Finally, when they were far enough from the cave, Odysseus let go of the rams belly and helped his men to do the same. They drove the sheep to their awaiting ship, and once all men and animals were on board, the soldiers cried in relief at their narrow escape. Odysseus signaled for them to hush. He realized that they were still in range of the Cyclopss hearing. The men understood and quickly began to row the ship out to sea. But Odysseus could not resist taunting the Cyclops from the deck of the ship. Cyclops, Odysseus shouted, you did wrong by trapping us, and now the gods have punished you. The Cyclops grew furious. In his rage, he ripped off the top of a mountain and hurled it toward the sound of Odysseuss voice. The piece of the earth plunged into the water just in front of the ship. This caused a wave that carried the ship back toward the Cyclops's land. Odysseus picked up a long stick and quickly drove it into the sea to stop the motion of the ship. He nodded his head toward the men, indicating that they must row for their lives, which they did. Odysseus was so angry he could not resist insulting the Cyclops further. Monster, he yelled, if anyone asks you how you lost your sight, you can tell them that it was I, the valiant warrior Odysseus. The Cyclops grabbed a giant piece of land, even larger than the first, and threw it with all his might. This time, the wave it caused drove the ship toward the island, where the rest of the soldiers were anxiously awaiting Odysseuss return.In the story adapted from Book IX of The Odyssey, what does Odysseus's scheme involving the sheep reveal about him?A: He is an expert fighter.B: He is unnecessarily cruel.C: He is a cunning strategist.D: He is motivated by fear. 1.a word picture2.responsible for the first collection of songs and lyrics in England3. something that can be perceived by the senses4. means little song in Italian5. wrote Italian sonnet6.
