What is one theory to explain what happened to the settlers at roanoke? a) they secretely returned to england. b) they assimilated and lived among the native americans. c) they joined a french settlement in canada. d) they were abducted by aliens.

B is the correct answer.

Many believe that the settlers were either taken or joined the local tribe out of desperation.

Evidence for this is the introduction of genes for characteristics that are not endemic to the native people of the region.

just finished this it is b. centrifugal force

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".
