Question 4Consider This Diagram.(6x+30)(8x+10)Given: M/CEA (8z + 10); M/AED (6x +30)Prove: == 10Part

Answers

Answer 1

The angles m∠CEA and m∠AED are supplementary thus the value of x will be 10 has been proved.

What is an angle?

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

m∠CEA and m∠AED are only two angles on a straight line thus they will be supplementary.

Therefore,

m∠CEA + m∠AED = 180°

8x + 10 + 6x + 30 = 180

14x + 40 = 180

14x = 140

x = 10

Hence "The value of x will be 10 has been proven since the angles m∠CEA and m∠AEDare complementary".

Colloids are a type of mixture where particles are dispersed throughout a medium, creating a stable and homogeneous mixture. In colloids, the particles are larger than those in solutions but smaller than those in suspensions. Option B is the correct answer.

Paint is a colloid because it consists of small pigment particles dispersed in a liquid medium, such as oil or water. These particles do not settle over time and the mixture appears uniform.

The minerals might have been framed simultaneously. What is important is that normal process stuck them all together.

There are three main types of rocks: sedimentary, igneous, and metamorphic. Every one of these rocks are shaped by actual changes, for example, dissolving, cooling, disintegrating, compacting, or twisting that are important for the rock process.

Deposition is the geographical process in which silt, soil and shakes are added to a land structure or landmass. Wind, ice, water, and gravity transport recently endured surface material, which, at the deficiency of enough motor energy in the liquid, is saved, developing layers of residue.

Deposition happens when the powers liable for dregs transportation are not, at this point adequate to conquer the powers of gravity and erosion, making a protection from movement.

He defeated the other six major states one by one, using a combination of superior military strategy and diplomacy. Once he had conquered these states, Shi Huangdi set about centralizing his rule by consolidating power in the hands of the emperor and the central government. He created a centralized bureaucracy to govern the empire, and appointed officials to administer the provinces and local governments.

Shi Huangdi also standardized legal and administrative systems throughout the empire. He created a uniform legal code, standardized weights, and measures, and standardized the writing system. This helped to create a sense of unity among the people of China and made it easier for the central government to exert control over the empire.

The point Submit Test Reader Tools lies on CD is (17, 0)

Point (-2, 19) lies on CD

Find slope of AB:

\(m = \frac{y2 - y1}{x2-x1}\)

x1, y1 = (-10, -3)x2, y2 = (7, 14)

\(m = \frac{14 + 3}{7 +10}\)

m = 1

Therefore,

1 × slope of CD

slope of CD = -1

Substitute m = -1 and (x, y) = (5, 12) in eq. 1

12 = -1(5) + c

c = 12 + 5

c = 17

Substitute m = -1 and c = 17 in eq. 1

y = -x + 17 ------ eq. 2

The x-intercept is found by setting y equal to 0

x = 17

Is Greece a primate or rank-size city, explain.

Greece is a rank-size city. A rank-size city is a city whose population size follows a predictable pattern based on their rank. In a rank-size city, the population of the largest city is always the largest by a factor of 1/n, where n is the city's rank.

Therefore, the population of the second-largest city is 1/2 times the population of the largest city, the population of the third-largest city is 1/3 times the population of the largest city, and so on.  This pattern is known as Zipf's Law and it holds true for many cities around the world, including those in Greece.

Athens, which is the largest city in Greece, has a population of approximately 3.7 million people, making it the 56th largest city in the world. Thessaloniki, which is the second-largest city in Greece, has a population of approximately 1.1 million people, making it the 246th largest city in the world.

The rest of the cities in Greece follow a similar pattern, with their populations being proportional to their rank. This makes Greece a rank-size city. Overall, the rank-size distribution of cities is a useful way of understanding urban systems and can provide insights into the underlying economic and social processes that drive urban growth and development.

Spring tides occur twice a month. This is when the sun and moon exert a combined gravitational pull on ocean waters. Spring tides occur during the new moon and full moon phases of the moon. The gravitational pulls of the sun and moon combine, resulting in higher high tides and lower low tides during these periods.

What is a spring tide?

A spring tide is a type of tide that occurs when the gravitational forces of the sun and the moon align and combine, resulting in particularly high high tides and low low tides.

During a spring tide, the sun, moon, and Earth are in a straight line, with the gravitational pull of both the sun and the moon reinforcing each other.

This alignment causes the ocean waters to be pulled in the same direction, leading to a greater difference between high and low tide levels.

When a forest is set on fire by cinders from a neighboring volcano, or when a tree is set ablaze by a thunderbolt, we may say that nature strikes a match. In the early history of the world, nature had to kindle all the fires, for man by his own effort was unable to produce a spark. The first method, then, of getting fire for use was to light sticks of wood at a flame kindled by natureby a volcano, perhaps, or by a stroke of lightning. These firebrands were carried to the home and used in kindling the fires there. The fire secured in this way was carefully guarded and was kept burning as long as possible. But the flame, however faithfully watched, would sometimes be extinguished. A sudden gust of wind or a sudden shower would put it out. Then a new firebrand would have to be secured, and this often meant a long journey and a deal of trouble.In 1827, John Walker, a druggist in a small English town, tipped a splint with sulphur, chlorate of potash, and sulphid of antimony, and rubbed it on sandpaper, and it burst into flame. The druggist had discovered the first friction-chemical match, the kind we use to-day. It is called friction-chemical because it is made by mixing certain chemicals together and rubbing them. Although Walker's match did not require the bottle of acid, nevertheless it was not a good one. It could be lighted only by hard rubbing, and it sputtered and threw fire in all directions. In a few years, however, phosphorus was substituted on the tip for antimony, and the change worked wonders. The match could now be lighted with very little rubbing, and it was no longer necessary to have sandpaper upon which to rub it. It would ignite when rubbed on any dry surface, and there was no longer any sputtering. This was the phosphorus match, the match with which we are so familiar.What is the main idea of this text? Firebrands were hard to keep lit. Nature provided fire to early humans. The history of the match is interesting. The match made life easier for humans.
