Question

A ___________ is any quantity that always has the same value.

(a) Variable

(b) Constant

(c) Function

(d) Stable

The 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 1

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.
