Will give brainiest if you get it ! is the following definition of supplementary reversible. if yes, write it as a true biconditional. supplementary angles are two angles whose measures sum to 180 a)yes, if angles are supplementary, then their measures sum to 180 b)yes, angles are supplementary if (and only if) their measures sum to 180 c)yes, angles are supplementary if their measures sum to 180 d)the statement is not reversible

Aparallel system functions whenever at least one of its components works. consider a parallel system of n components, and suppose each component works independently with probability 0.5. find the conditional probability that component n works given that the system is working

Agroup of students want to create a garden. they do not know the exact measurements but they propose using a variable to represent the length and width of the garden. the length of the garden is 10 feet longer than double the width. use a single variable to write algebraic expressions for both the length and width of the garden. write an algebraic expression for the area of the garden. use mathematical terms to describe this expression.

If the scale factor between two circles is 2x/5y what is the ratio of their areas?
