By definition, two rays labeled AB and AC must exist with which of the following conditions? Select ALL that apply! The two rays make a line AC The two rays are parallel The two rays form angle CAB D The two rays are perpendicular E The two rays intersect at point A​

Answer:

The two rays form angle CABThe two rays intersect at point A​

Explanation:

An angle is formed of two rays having the same endpoint. Angle CAB will be formed from rays AB and AC. Those rays will intersect at their end point: A.

__

Comments on other choices

The two rays will make line AC if and only if point A lies between points B and C on that line. That is, the existence of rays AB and AC do not guarantee that a line will be formed.

Parallel rays cannot share a point. Hence rays AB and AC, which share point A, cannot be parallel.

A letter is a written communication sent from one person to another via a medium. Something epistolary denotes a type of letter writing. The term typically excludes written material intended to get read in its original form by a large number of people, such as newspapers and placards, though even these may contain material in the form of a "open letter."

For many centuries, and still today, the typical form of a letter is a sheet made from paper sent to a correspondent via postal service.

2. Which month would be the best month for tourism in Merida, Mexico?
a. June
b. January
C. September
d. All of the above

Answers

Answer:

January is the best month for tourism in Merida, Mexico.

Explanation:

When we think of tourism, especially at places where people go to go swimming, sunbathing, enjoy the weather, we often have summer in our minds as the best time. This is not always the case though, and in fact, there are many places around the world that it is the winter months that are better for tourism. One of those places is Merida, Mexico.

The best month for tourism in Merida is actually January. This is due to the fact that the temperatures in January are the best, with the days being warm, while the nights fresh. Also, there is little rainfall during this month, so the sun and relatively stable weather are almost a given. This can not be said for the months like June and September though, as the temperatures are too high, humidity is too high, and there is a lot of rainfall.

Match the climate change term in column 1 to the characteristics in column 2.

Answers

Answer:

Human activity - Produces greenhouse gasses.

Greenhouse gasses - Cause atmosphere to trap more heat.

Sun's output - Can vary.

Ice age - Peaked 20,000 years ago.

Explanation:

Human activity includes the usage of fossil fuels on a very large scale, and by using them we release huge amounts of greenhouse gasses into the atmosphere.

The greenhouse gasses have the ability to trap the heat that is reflected from the surface of the planet, thus keeping more of it in the atmosphere and causing global temperature rise.

The sun is technically a star, thus an object that produces energy and light, and like every star, it has variations in its activity in accordance with the processes going on on it.

There have been numerous ice ages through the geological past, and the last one of them ended only around 10,000 years ago, with its peak being just 20,000 years ago.

The two types of water scarcity are __________ and __________.

A. Resource . . . Physical
B. Physical . . . economic
C. Economical . . . Climatic
D. Physical . . .Climatic

Answers

Answer:

B: Physical & Economic

Explanation:

Physical water scarcity occurs when and where there is not enough water to meet both human demands and those of ecosystems to function effectively. Arid regions frequently suffer from physical water scarcity. It also occurs where water seems abundant but resources are over-committed.

Economic water scarcity is caused by a lack of investment in water infrastructure or insufficient human capacity to satisfy the demand of water in areas where the population cannot afford to use an adequate source of water.

The answer to the question is B. The world’s arable farmland is unevenly distributed.

Not all soil is suitable for growing, like permafrost soil and soil that is too packed together.

Not every climate can support crops, like in Russia, there is permafrost ( soil that is frozen all year) that makes it hard to plant crops. It is also too cold for crops there.

Not all countries have the resources to grow food. Some countries may rely on hunting or fishing for food.
