Answer:
5
Explanation:
3 (2×-7)=9
6×-21=9
6×=9+21
6×=30
6×/6=30/6=5
×=5
In the equation 3(2n-7)=9, the value of n is 5. An equation represents a mathematical formula in which the equality of two statements is expressed by connecting with them the equals sign =.
Given,
3 (2n-7)=9
6n-21=9
6n=9+21
6n=30
6n/6-30/6-5
N=5
An equation represents a mathematical formula in which the equality of two statements is expressed by connecting with them the equals sign =. The word equation and its cognates in various languages may have somewhat different definitions; for example, in French, an équation is defined as including one or more variables, whereas in English, an equation is any well-formed formula comprising of two expressions linked by an equals sign.

C. Monsoons create a perfect environment for rice farming.
D. Monsoons can cause devastating landslides and floods.
Answers
Answer:
D. Monsoons can cause devastating landslides and floods.
Explanation:
Monsoons require a large area of land and oceans, they occur where large bodies of water are limited to large land areas.
Monsoons are formed on the shores of certain oceans in both the southern and northern hemispheres. The most pronounced monsoons are formed over the Indian Ocean and the southern part of Asia. They come to it in the summer and start from the Himalayas during the winter.
What is the name and reason why there is a band between the two hemispheres where no hurricanes occur
Answers
Answer:
In the equator region there are almost no earthquakes because of the lack of corolian strength in that region.
Explanation:
The corolis force moves large layers of air at rapid speed, which is one of the main factors in the formation of hurricanes and cyclones. This force is also responsible for the movement of ocean currents. A curious fact about the corolis force is that it promotes the movement of the winds in one direction in the southern hemisphere and promotes the same movement in the northern hemisphere, but in the opposite direction. However, the meeting point between these two movements promotes zero movement intensity, which makes hurricane formation difficult. This region of zero movement is the equator.
what are tectonics wegener theory
Answers
Answer:
Alfred Wegener first presented his hypothesis to the German Geological Society on 6 January 1912. His hypothesis was that the continents had once formed a single landmass, called Pangaea, before breaking apart and drifting to their present locations.Plate tectonic theory had its beginnings in 1915 when Alfred Wegener proposed his theory of "continental drift." Wegener proposed that the continents plowed through crust of ocean basins, which would explain why the outlines of many coastlines look like they fit together like a puzzle.

Describe the main causes that are responsible for over consumption of forest
Answers
Answer: Lumber is cut down for fire. These lumberjacks are mostly responsible for consumption in the forest.
Explanation:
The primary causes of deforestation and severe forest degradation are agriculture, poor forest management, mining, infrastructure projects, an increase in the frequency and intensity of fires, and agriculture.
What is the cause and effect of deforestation?Deforestation is the destruction of forest habitats for activities like mining, farming, or urban development. It happens everywhere in the world. Deforestation, which has been significantly increased by human activity since 1960, has been detrimental to natural ecosystems, biodiversity, and the climate.
Deforestation is a natural result of many factors, including forest fires and extreme droughts. Deforestation results from forest fires because they burn a lot of trees. Trees perish during extreme droughts because there isn't enough water available.

Identify and describe the two main methods for measuring the age of Earth and its parts

Explanation:
Answer:
The three primary methods are: Radiation Measurement. Stratigraphic Superposition. The Fossil Record.
Explanation:
To establish the age of a rock or a fossil, researchers use some type of clock to determine the date it was formed. Geologists commonly use radiometric dating methods, based on the natural radioactive decay of certain elements such as potassium and carbon, as reliable clocks to date ancient events.The best estimate for Earth's age is based on radiometric dating of fragments from the Canyon Diablo iron meteorite. From the fragments, scientists calculated the relative abundances of elements that formed as radioactive uranium decayed over billions of years.
What causes the wavelength of a particular beam of light change?
Answers
Answer:
Wave speed, frequency and wavelength in refraction
Explanation:
Although the wave slows down, its frequency remains the same, due to the fact that its wavelength is shorter. When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases.
Wave speed, wavelength in refraction and frequency causes the wavelength of a particular beam of light change.
What is wavelength of a light?The wavelength of light is the separation between both the two crests or troughs of the light wave. It is recognized by the Greek letter lambda (). Therefore, the term "wavelength" refers to the distance between the crest or trough of one wave and the wave that follows it.
The number of waves that travel through a single location in a specific amount of time determines frequency, and the distance between two subsequent troughs or crests determines wavelength. As a result of the inverse connection between wavelength and frequency, frequency falls as wavelength increases.
The wave slows down, but because its wavelength is shorter, its frequency doesn't change. Waves' frequency does not alter as they go from one medium to another. Waves slow down and shorten in wavelength when they move through denser media.
