Answer:
x=20
Explanation:
3x-10+5x+30=180 (co-interior angles=180)
8x+20=180
8x=160
x=20
Answer:
The statement suggests that the Aryans originated in India, but in reality, they originate from the steppes of Eurasia.
Explanation:
The Aryans were an ancient group of people that formed as such in the Eurasian steppes, mostly in the close area north of the Black and Caspian Seas. Because the populations were growing but the resources were very limited, these warlike people groups started to migrate in order to find other suitable places for living.
The migrations went in numerous directions, with the majority moving toward the south in what is now Iran, southeast in the Indian subcontinent, and west toward Europe. These migrations resulted in spreading out of a gene pool, culture, and language with the same basis over a very large area. The Aryans lived in India and their descendants still do, and so is their language, but this is the case in Europe as well. Over thousands of years though, the isolation between the groups has resulted in the divergence of the language and creation of numerous different languages, but they all belong to the same group and have the same origin.
The correct answer is J. Arab-Israeli wars.
Explanation
The conflict between Israel and Palestine is a social and armed conflict that originated at the beginning of the 20th century. However, this confrontation became more acute after the end of the Second World War since the partition of what had been the British mandate in Palestine was approved, assigning about 7% of the lands of Palestine to the Jewish people. This triggered the expulsion of two thirds of the Palestinian population to different parts of the planet, especially to surrounding countries such as Jordan, Lebanon, Saudi Arabia, Qatar, Oman, among others. So the correct answer is J. Arab-Israeli wars.
Answer:
b. wind waves, seiches, tsunami, tides.
Explanation:
The wavelength of water waves is calculated measuring the distances between the trough (low point) portion of a wave. Usually, the bigger the wave, the greater the wavelength.
wind waves: small waves caused by the wind. These waves tend to be small and with a short wavelength.
seiches: are usually waves on a lake or other closed water bassin. They can be pretty high from a human perspective, so they are definitely bigger than wind waves.
tsunami: we all know how big the waves of a tsunami can be, totally wiping out coastal cities they encounter, so that's pretty big waves, and big waves tend to be larger apart (so with a bigger wavelength) than smaller ones.
tides: yes, a tide can be considered as a huge wave... that's running throughout the planet. We barely see it as a wave because we can only see one wave at a time, the next wave being tens of thousands of mile away.
