Point M is the midpoint of segment AB. If AM = 50 – 3x and MB = –20 + 4x, find the value of x.
Answer:
10
Explanation:
To find the value of x, equate the lengths of AM and MB as point M is the midpoint of segment AB. By solving the equation 50 - 3x = -20 + 4x, we find x = 10.
Explanation:To find the value of x, use the fact that point M is the midpoint of segment AB, meaning AM = MB. So, set 50 - 3x equal to -20 + 4x and solve for x:
50 - 3x = -20 + 4xCombine like terms: 7x = 70Divide by 7 to find x: x = 10What is the name of an impression formed when tiny plants or animals become trapped between sediment layers?
The inca empire was the largest nation on earth and remains the largest native state to have existed in the Western Hemisphere. True or false
Answer:
True
Explanation:
Incan or Inka empire was the largest empire in pre-Colombian America and was developed before the arrival of the coulombs. With an areal expanse of 2,000,000 km square. It largely functioned without money and markets. And is believed to the large scale empire of the Andes 1100 AD. Thus its characters are derived from the multi-ethnic and Andean culture and existed in the western hemisphere.The Inca Empire was the largest empire in pre-Columbian America and was the largest native state in the Western Hemisphere. It spanned from Ecuador to Northern Chile and from Colombia to Argentina, with Cuzco as its political and administrative center. The correct option is: True.
The statement that the Inca Empire was the largest nation on earth and remains the largest native state to have existed in the Western Hemisphere is true. Before the era of European colonialism, the Inca Empire was indeed the largest empire in existence, extending from Ecuador to northern Chile, and reaching from Colombia down to modern-day Argentina at its peak.
This pre-Columbian state, which originated in the highlands of Peru, saw its power expand considerably in the 15th century, controlling vast territories along the Andes but also including coastal areas and parts of the Amazon rainforest. With Cuzco as its capital and center of administration, the Incas developed a sophisticated society known for its monumental architecture, extensive road systems, and innovative agricultural practices such as terraced farming.
At first, hernan and cortese was welcomed by the aztec ruler. true or false?
"The statement "At first, Hernan and Cortes was welcomed by the Aztec ruler" is true.
When Hernando Cortes and his men arrived in the Aztec capital of Tenochtitlan in 1519, they were initially welcomed by the Aztec ruler, Moctezuma II (also spelled Montezuma). Moctezuma's actions were influenced by a complex mix of factors, including the belief that Cortes might be the returning god Quetzalcoatl, as well as a strategy to gather information and assess the strength of the Spanish forces. The initial welcome, however, did not last long, as tensions soon escalated, leading to conflict and the eventual conquest of the Aztec Empire by the Spanish."
How thick is the outermost layer of the Earth?
The Earth's outermost layer, the crust, ranges in thickness from 6 to 70 kilometers. The oceanic crust is approximately 6 kilometers thick and the continental crust ranges from 20 to 70 kilometers.
The thickness of the outermost layer of Earth, known as the Earth's crust, varies depending upon its geographical position. The oceanic crust, which covers 55% of the Earth's surface, is about 6 kilometers thick and mainly composed of basalt. On the other hand, the continental crust, which covers 45% of the surface, ranges from 20 to 70 kilometers in thickness and predominantly consists of granitic rocks. So overall, the thickness of the Earth's crust ranges from 6 to 70 kilometers but accounts for only about 0.3% of the total mass of Earth.Learn more about Earth's outermost layer here:

When studying historical geology, which type of rock provides the most useful evidence for uncovering what occurred in the past?
metamorphic
sedimentary
igneous
basalt
igneous
granite
Answer:
From the point of view of historical geology, sedimentary rocks (option B) have characteristics that allow to be the most useful to discover the events that occurred in the past.
Explanation:
Sedimentary rocks are the product of the lithification of the sediments of rocks originated by the weathering (meteorization) process, transported in the form of particles by environmental agents such as wind, rain, sea swell, among others.
The sediments that are deposited on the surface of the planet, over many years, go through a hardening process that turns them into rocks with heterogeneous material. The characteristics that make sedimentary rocks the ideal material for historical geology studies are:
The formation process, where particles from past eras are found. Its structure more or less accurately indicates the environmental conditions of the time they originated. They contain information about their formation mechanism. Fossils, also evidence of past times, are found in sedimentary rocks.In order for geologists to reconstruct events and characteristics of the past, sedimentary rocks provide valuable information that contributes to this work.

What type of texture results when extrusive igneous rock cools so quickly that crystallization does not occur. A.glassy. B. Aphanitic. C.phaneritic. D.porphyritic
The texture that results when extrusive igneous rock cools so quickly that crystallization doesn't occur is glassy. This texture is due to the rapid cooling process, which doesn't allow the formed minerals the time to crystallize.
Explanation:When extrusive igneous rock cools so rapidly that crystallization does not occur, the texture that results is glassy. This rapid cooling process denies the minerals within the lava the time to form crystals, thus resulting in an amorphous or glass-like structure. Examples of this type of rock include obsidian and pumice. On the other hand, Aphanitic texture is where the crystals are too small to see with the bare eye, usually because the rock cooled quickly. Phaneritic texture indicates that the rock cooled slowly, allowing the crystals to grow large enough to be seen without magnification. Porphyritic texture appears in rocks that cooled slowly at first, then more rapidly.

Which of the following statements is true?
A. Lithification is the formation of igneous rock from sedimentary rock.
B. The rock cycle is powered by the movement of tectonic plates.
C. Metamorphic rock cannot form from preexisting metamorphic rock.
D. Subduction changes metamorphic or igneous rock into sedimentary rock.
The true statement is - B. The rock cycle is powered by the movement of tectonic plates.
Almost all rocks on our planet came to existence because of the tectonic activity. The movement of the tectonic plates is enabling the magma from the mantle layer to come to the surface, cool off, and create new layers of rocks. On the other hand, the same process, where there's subdustion zones, is moving the existing rocks down into the mantle layer where they are ''recycled'' in way, and this process is continuing to happen all the time.

Calligraphy is an important art form, and it takes many years to learn how to create Chinese characters.
C.
The exact same written characters are used in all Chinese dialects and in Japanese.
D.
Across cultures in East Asia, many people cannot communicate by speaking, but can read the same writing.
The false statement is that the exact same written characters are used in all Chinese dialects and in Japanese. While there are similarities, the two are not exactly the same, and Japanese incorporates two other scripts. Students of East Asian languages, as well as artists studying calligraphy, have to learn the nuances of these diverse scripts.
Explanation:The false statement about language in East Asia among the given options is C: 'The exact same written characters are used in all Chinese dialects and in Japanese'. While there is significant overlap, particularly due to Japanese use of kanji, which originated from Chinese characters, the two writing systems are not exactly the same. Additionally, Japanese incorporates two other scripts called hiragana and katakana, and China's various dialects sometimes use distinct characters.
Statement A is partially correct as the modern Korean language uses hangul script but also employs classical Chinese characters, especially for formal or academic writings. Statement B is true; calligraphy is indeed an esteemed art form in East Asia that involves creating Chinese characters. Statement D reflects the phenomenon that, even though spoken languages in East Asia can be mutually unintelligible, the widespread use of Chinese characters in writing enables a certain level of intercommunication.
