Answer:

x=2

Explanation:

I'm guessing that CB and BD are the two lengths that make up CD, so you would add up CB and BD to get CD.

2x+4x=12

Answer:

A geographic studying an ecosystem would look at:

the relationships between human activity and natural systemswhere things are located on the surface of the earthwhy they are located where they arehow places differ from one another, and how people interact with the environment

To comprehend an ecosystem's structure, function, and relationships, a geographer researching it would examine a variety of the ecosystem's features. They would research the geography, climate, hydrology, and landforms of the region.

The ecosystem's biological components, such as plants, animals, and microorganisms, would be examined by geographers. They would look into the diversity of species, population dynamics, and ecological connections.

The impact of human activity on the ecology would be taken into account by geographers. The effects of human activities like deforestation, urbanization, agriculture, pollution, and resource extraction will be evaluated.

predict what happens when regional boundaries are contested,overlapping, and/or transitional.

Answers

Answer:

Contesting boundaries always comes with tension.

Explanation:

It's not so much as the boundaries themselves that elicit the political tension and loggerheads. The primary factor is that it is the resources within those boundaries that are being contested for.

Resources which enrich the state and or country, resources that affect the livelihood of the people living in those geographical locations.

Changes in boundaries may translate to increased unemployment and vice versa and no region wants to be on the receiving end of the negative aftermaths.

Write a paragraph explaining which climate zone you would live in and why?

Answers

Answer:

I would want to live in the tropical climate zone.  During the summer, tempertures tend to average into the 90s, which is perfect for me considering I'm always complaining about being too cold.  Winters rarely drop below the 40s in this climate zone. Assuming I lived near the ocean in the tropical climate zone, I would spend my days hanging out on the beach, and enjoying myself and the ocean breeze.

We cannot be sure about population size in the future, anything could happen. How might these affect: global warming melts all the ice in antarctica and a deadly superbug appears.Antibiotics cannot kill it. Brainly in

Answers

Answer:

I'm not sure what the question is. If the Icecaps melt (north & south), including glaciers, the water levels will rise, and a mass migration would occur due to the rising Sea levels many countries won't exist anymore! Add a superbug, and it will result in catastrophic mass casualties. Either scenario will have enormous consequences for all of humanity. The reality is it’s already happening now, mass migration from war-torn countries in north Africa and other regions are trying to flee to survive, but it’s not as simple as to go to higher ground. Countries/regions on a higher ground cannot support the influx of refugees; thus, they won’t allow entry, and the people will perish. Every scenario is pointing to a total collapse of the current world and inevietably war. Of course, it’s not the end of the world, but close. Some humans will survive in remote areas, not directly affected by rising water levels or pandemics and war, but it won’t be pretty since most infrastructures will have to be rebuild.  It would set humanity set back to the pre-industral area.

Mechanical weathering

Explanation:

Weathering is defined as the process by which rock materials are broken down by the action of physical or chemical processes. Physical weathering is known as mechanical weathering, where rocks breakdown into smaller pieces by mechanical means.

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away

Answer:

Mechanical weathering (also called physical weathering) breaks rock into smaller pieces.

EXPLANATION:

Erosion happens when rocks and sediments are picked up and moved to another place by ice, water, wind or gravity. ... When the water freezes it expands and the cracks are opened a little wider. Over time pieces of rock can split off a rock face and big boulders are broken into smaller rocks and gravel.

Write an equation in slope intercept format of the line that is a segment bisector of both AB and CD. A(-1,8) B(3,4) C(1,10) and D(7,8) find y. ​

Answers

Answer:

y = x + 5

Explanation:

The equation of a line in slope intercept form is y = mx + c, where m is the slope and y is the intercept

The midpoint or bisector (x, y) of a line with endpoints at ([tex]x_1,y_1[/tex]) and ([tex]x_2,y_2[/tex]) is given by:

[tex]x=\frac{x_1+x_2}{2}\\ \\y=\frac{y_1+y_2}{2}[/tex]

If AB is at A(-1,8) B(3,4), the coordinates of the midpoint of AB is:

[tex]x=\frac{x_1+x_2}{2}=\frac{-1+3}{2}=1 \\ \\y=\frac{y_1+y_2}{2}=\frac{8+4}{2} =6[/tex]

The midpoint of AB is (1, 6)

If CD  is at C(1,10) and D(7,8), the coordinates of the midpoint of CD is:

[tex]x=\frac{x_1+x_2}{2}=\frac{1+7}{2}=4 \\ \\y=\frac{y_1+y_2}{2}=\frac{10+8}{2} = 9[/tex]

The midpoint of CD is (4, 9)

The equation of the line passing through two points is given as:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)\\ \\The \ equation \ of\ the\ line \ passing\ through \ the\ midpoint\ of\ AB, i.e (1,6)\ \\and\ the\ mdpoint\ of\ CD\ i.e(4,9)\ is:\\\\y-6=\frac{9-6}{4-1}(x-1)\\ \\y-6=1(x-1)\\\\y=x-1+6\\\\y=x+5[/tex]
