Because its heavy and it was available
To change the equation, you'd have to take the square root of both sides. When you do this, x^2 cancels out leaving you with x = sqrt(y)
If you need help on the other ones, all you have to do is solve for x by using either addition/subtraction or dividing/multiplying.

Answer:
TRUE
Explanation:
Cinder cones are usually characterized by the cone-shaped, steep sloping volcanoes, and are typically comprised of pyroclastic materials. These volcanoes have a slope of about 30° to 40° and have a summit at the mouth of the volcano. They are of short height and are found mostly adjacent to the bigger volcanoes such as strato-volcanoes and central vent volcano. They erupt at a much faster rate compared to the long-lived ones.
Thus, the above-given statement is True.
Answer:
An analysis of 5,000-year-old genetic material from preserved human remains found in Sweden suggests that people moving from southern to northern Europe spread agriculture across that continent long ago.
In addition to agricultural know-how, the intrepid farmers brought their genes: They interbred with hunter-gatherer communities to create modern humans living in Europe today.
"Genetic variation of today's Europeans was strongly affected by immigrant Stone Age farmers, though a number of hunter-gatherer genes remain," study researcher Anders Götherström, of Uppsala University in Sweden, said in a statement.
The results of this study, to be published in the April 27 issue of the journal Science, match up well with previous archeological evidence of farming in Europe.
