Answer:

Star A is 3.343 times hotter than star B.

Explanation:

It is known that the luminosity of a star is proportional to its effective temperature to the 4th power. This means that the ratio between the brightness of stars A and B is equal to the ratio between their temperatures to the 4th power:

125=T^4\\T=\sqrt[4]{125}\\T=3.343

Star A is 3.343 times hotter than star B.

Answer:

105°

Explanation:

Two angles are linear if their angle measures add up to 180°. (This is also known as vertical angles.)

If we know the measure of one angle, we can easily find the measure of the other, assuming x is the missing angle:

75 + x = 180\\\\x = 180-75\\\\x=105

Hope this helped!

Which factor has led to the increasing influence of oil-rich Middle Eastern countries over other nations?
monitta

Answer:

The dependence comes from the fact that the highest consumers of oil are not the highest producers.

Explanation:

The Middle East, as a region, has been blessed with reserves of oil. This is the natural resource for which there is the highest demand on the global market, so having it means that it brings a lot of benefits. The most obvious benefit is a lot of profit, but there is also the political influence because of the dependence of other countries on the resource.

The huge amount of profit complemented with having all major economies in the world (except two) highly dependent on oil from the Middle Eastern countries has led to a lot of looking through fingers situations. Almost all of the countries in this region tend to be among the worst when it comes to the violation of human rights, suppression, dictatorship, but all other countries turn their heads and there is no reaction because of how dependent they are on their oil. Also, the leaders of these countries are spreading out their influence in other countries by buying a lot of businesses, buying actions, sports clubs, or even finance political parties in order to make a stronghold, and so far they do it to great effect.
