How did the geographic setting of north america- including its relation to asia, europe, and africa- affect its subsequent history?

The American continent is geographically inaccessible and secluded, separated by two oceans from any other countries.  

This made colonization (or invading a country) of North America which possibly only through a sea. That removed and eradicated nations with large armies as threats. The only power that could influence North America was a nation with a powerful and tough navy, like England’s.  

To our north countries like, Canada was resolved by the French, who were our alliances. To the south was Mexico, South America, and Central America.

Thus, at the start, North America had a geographic superiority against any conquering force: distance across an ocean. However, the United States of America can grow and establish their own identities separately from their parent and other countries.

part a. there were 250 teenagers surveyed (100% of tenagers = 250)therefore 1 % = 250/100 = 2.5 76% = 1% x 76 = 2.5 x 76 = 190 teenagers of the 250 surveyed liked burgerspart b: jane surveyed 25% (which is equal to 50 teenagers, i.e. a quarter of the teenagers surveyed is 50) to get 100% we simply get 4 quarters, i.e. multiply 50 by 4 = 200 teenagers were surveyed by jane. part c: it is impossible to give an example where a percentage is greater than 100%, since, by definition , percentage means "per 100".

it was the new england colonies.
