In which direction does weather typically move? a. from east to west c. from north to south b. from west to east d. from south to north

Answers

The answer is B: west to east

Weather can move in any direction. In the United States, weather most often moves west to east, because that is the direction the jet stream blows. The jet stream carries weather systems along with it.

Now, you may ask, why does the jet stream blow west to east?

The answer is complicated, but it happens as a result of the way the sun heats the equator more than the poles, and the speed with which the earth spins.

Hope this helps
The weather most often moves from west to east in US so the answer to this question is B

A. More education generally means more children per family
B. Less education means less opportunity, and thus fewer children
C. Educated women are more likely to pursue business
opportunities
D. Educated women tend to have fewer children​

Answers

Education and reproductive rates have a negative relationship. Generally speaking, educated women have fewer children than uneducated women. Thus, option D is correct.

What is the fertility rate?

The number of live births to women of a certain age throughout the year expressed as a percentage of the average yearly population of women of that age is known as the fertility rate at that age.

The fertility rate and education have a negative relationship. Women with more education tend to have fewer children than those without education.

Economic development can be seen as both a cause and a result of lower fertility rates: Positive effects of increased education on women's fertility are passed on to future generations due to lower fertility.

hi:) I’m quite confused about the relative humidity concept. Anyone able to explain? thank you so much!:)

Answers

Answer:

Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air.

Climate control refers to the control of temperature and relative humidity in buildings, vehicles and other enclosed spaces for the purpose of providing for human comfort, health and safety, and of meeting environmental requirements of machines, sensitive materials (for example, historic) and technical processes.

Relative humidity is the ratio between the actual humidity in a given volume of air and the maximum capacity of water vapour the same volume of air can hold at a given temperature. It is a measure of how much of the air’s capacity to hold water vapour has been used up.

Answers

Completed Question

Rectangle ABCD has four right angles.  (1)What is the sum of its angle measures? (2)Move vertex A to a different location. Which vertex angle remains  unchanged? (3)What is the sum of the angle measures of the quadrilateral?  (4) Move vertex B to a different location. What is the sum of the  angle measures of the quadrilateral?

Answer:

1. 360 degrees

2. Angle C

3. 360 degrees

4. 360 degrees

Explanation:

(1)By the properties of a rectangle, each of its angles is 90 degrees.

Therefore:

[tex]S$um of its angles =\angle A+ \angle B+ \angle C+\angle D\\=90^\circ+90^\circ+90^\circ+90^\circ\\=360^\circ[/tex]

(2)If we move vertex A to a different location, the two adjacent angles( B and D will change). Angle C however will not change as can be seen in the attached diagram.

(3 and 4)

The sum of the angle in a quadrilateral is always 360 degrees.

Therefore, the answer to Questions 3 and 4 is 360 degrees.
