What caused the Dust Bowl? (Site 1)

    Poor agriculture practices, harsh weather, removal of grasses

Explanation:

    The Dust Bowl was caused by people getting rid of the tall grasses that covered Texas´s plains, these grasses had roots deep into the soil that held on to the soil preventing it from flying away in the plains great wind speeds, these grasses´s roots also held onto water and nutrients making the soil very fertile.   Another thing that caused the Dust Bowl was it´s hot weather and poor agriculture techniques.

judaism developed through the growth of a single nation of people

christianity developed through followers spreading the religion throughout the world.

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".
