What land was used for the new capital of Washington, D. C.? What
year was the new capital moved?

President George Washington chose the exact site along the Potomac and Anacostia Rivers, and the city was officially founded in 1790 after both Maryland and Virginia ceded land to this new “district,” to be distinct and distinguished from the rest of the states.

Explanation:

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".
