Answer:
The correct answer would be - 3ab.
Explanation:
Given:
area of polygon = 1/2 (perimeter)(apothem)
let assume the length of a side of the hexagon = x
The length of the apothem = a
Formula used:
the perimeter of polygon = number of sides*length of the side
for hexagon = 6*x .....1
Solution:
As the formula for the area of a polygon is given, and the hexagon is a polygon as it has six sides then the area then,
Area of hexagon = (1/2)* (6x) (a)
= 6ax/2
= 3ax
put the value of a and x and get the numeric value.

(Q020) Identify the true statement. a. The geothermal gradient is the rate of change in pressure with depth in the Earth. b. The temperature at the Earth's center may almost equal the temperature of the Sun's surface. c. The calculated density at the Earth's center makes scientists almost certain that the inner core is composed of diamond. d. The pressure at the Earth's center is less than 300 times greater than normal atmospheric pressure.
Answer: b. The temperature at the Earth's center may almost equal the temperature of the Sun's surface.
Explanation:
The Earth's core is very very hot due to various factors such as heat from radioactive materials decaying and the heat the earth had when it was formed. It is estimated that the temperature here is around 5,200° C which means that it can melt even Tungsten.
This is almost equal to the surface temperature of the sun which is around 5,500° C.
What type of galaxy is described as having an elongated center and spiraling arms?
Barred spiral
Spiral
Irregular
Elliptical
Answer:
barred spiral
Explanation:
The galaxy which is described as having an elongated center and spiraling arms is a Barred spiral. Thus the correct answer is A.
What is Galaxy?A galaxy is a large collection of planets, celestial bodies, gas, and particles. Gravity keeps a galaxy together. A big black hole also resides in the center of our galaxy, the Milky Way.
A spiral galaxy termed a barred spiral universe has a star-focused central bar structure. In almost two-thirds of spiral galaxies, streaks are present.
Stars no more revolve in circular orbits when a large barrel arises instead, the bar has bent the stars' orbits, which is causing them to move into more circular orbits that pass close to the center of the galaxy.
Therefore, option A Barred Spiral is the appropriate answer.

In which of the following scenarios would using a GIS be helpful?
Ο Ο Ο
assessing the soil erosion risk within a watershed
providing navigation assistance to guide a lost driver to his destination
transcribing inaccurate historical data into accurate historical maps
calculating local time when crossing the International Date Line
analyzing the relationship between functional and formal regions
Answer:
providing navigation assistance to guide a lost driver to his destination
Explanation:
The scenario in which using a GIS would be helpful is when "providing navigation assistance to guide a lost driver to his destination."
This is because GIS (geographic information system) is a computer system that carried out many processes including getting, storing, checking, and presenting data related to different positions on Earth.
Hence, GIS can be used by different people to know their locations or their destination.
For example, GIS using GPS information in a car to know the current location and destinations of drivers in a specific area.

identify the statement that is true about soil-forming factors. a. Dry soils tend to contain more organic material than wet soils contain, because wet soils drown vegetation. b. Different plant types can add or remove nutrients within a soil, thereby changing the type of soil that is formed. c. Soil that forms on basalt bedrock will be the same as soil formed on granite bedrock because they are both igneous bedrocks. d. Soil that forms on steep slopes is thicker than soil formed on flat land because of the accumulation of sediment on slopes.
Answer: b. Different plant types can add or remove nutrients within a soil, thereby changing the type of soil that is formed.
Explanation:
Some plants require more a of particular nutrient than others and so will draw more of these nutrients from the soil whilst giving away some of the ones that they do not want. This is one of the reasons that some plants grow better in a particular area than not.
When these plants give or take away nutrients, they would be changing the type of nutrient composition of the soil and this is what makes crop rotation so effective.
In a paragraph of not more than 8 lines describe the reasons for the difference in the population density of South Africa and England.
Hey there! I'm happy to help!
Both South Africa and England have a similar populations. However, these countries have different population densities. Population density is how crowded the country is with people. South Africa is a much larger country in terms of its area while England has a smaller land area. If they have similar populations, but different amounts of space, one is going to have a higher population density. Since England has less space, it has a higher population density as there are more people in a smaller space. There is more land area in South Africa, so this naturally makes it less crowded.

Some government officials dismissed these concerns, since statistics indicated that global atmospheric ozone levels remained constant. The relevance of the evidence cited by the government officials in support of their position would be most seriously undermined if it were true that

Even where the amount of atmospheric ozone is normal, some ultraviolet light reaches the Earth's Surface.

Factors that contribute to nation building are good governance, a united and inclusive society and a flourishing business community.
Great nations with great and working economies we not built in a day, but took a number of concerted efforts over time between the government and its citizen to bring such nations into limelight and a beacon for others to follow. Recommendations for building up a great nation is centred on three factors viz:
1. Good governance
2. United and inclusive society
3. Cooperative business community.
These factors listed above are crucial because it produces a society that is united, can fend for itself and harmonized in tackling challenges that cuts across all sectors such as socioeconomic development, inequality etc...
With a prospering business community, especially in instances where small and medium scale businesses are allowed to flourish and develop to their full potentials, it is seen that the income inequality is quickly bridged, thus raising the standard of living of such countries and helping to eradicate poverty. This also boosts local manufacturing and subsequently international trade with other nations thus forming meaningful ties and allies.
A government vested on good and quality educational system not only creates a sense of belonging and national unity through school curriculum, but also to develop creative and progressive minds that get to form the very fabric of the nations' financial institutes, research institutes, civil workers, engineers, future teachers, businessmen and women etc.
A society that is more equal than it was yesterday, is always one step ahead towards the goal of nation building. This is true in all aspects; a nation has to be inclusive, accommodating, diverse,...with a government with a good developmental and sustainable plan to steer the nation forward in future times to come.

which areas of Earth receive the greatest and the least solar irradiance?
Answer:
hope this helps
Explanation:
Earth receives different amounts of solar energy at different latitudes, with the most at the equator and the least at the poles
Answer: this is the answer
Explanation:
The regions closest to the equator receive the most direct sunlight because the light is arriving at an angle close to 0°. As a result, a lesser area is illuminated and so there is greater solar irradiance. The regions nearest to the poles receive sunlight at more of an angle, resulting in a larger area of illumination and therefore less solar irradiance.
