A ___________ is any quantity that always has the same value.(a) Variable(b) Constant(c) Function(d) StableThe question was posed to me in an internship interview.I want to ask this question from Nomography topic in chapter Nomography, Computer Aided Drafting & Procedure of Estimating of Civil Engineering Drawing

Answer» CORRECT choice is (b) CONSTANT

To explain I would say: A fixed value.

In Algebra, a constant is a NUMBER on its own, or sometimes a LETTER such as a, b or c to stand for a fixed number.

Example: in “x + 5 = 9”, 5 and 9 are constants

If it is not a constant it is called a variable.
