# An equation that expresses a relationship between two or more variables, such as H=9/10(220-a), is called a/an? The process of finding such equations to describe real-world phenomena is called mathematical ? Such equations, together with the meaning assigned to the variables, are called mathematical ?

This article aims to find the definition of formula, modeling, and models. This article uses the concept of formula, modeling, and models. In mathematics, a formula is a fact, rule, or principle expressed using mathematical symbols. Examples of formulas include equations, equalities, identities, inequalities, and asymptotic expressions.

A mathematical model usually describes a system using a set of variables and a set of equations that establish relationships between the variables. Variables can be of many types; for example, real or integer numbers, Boolean values, or strings. Variables represent some properties of system, for example the outputs of the measured system often in the form of signals, time data, counters and occurrence of events. A real model is a set of functions that describe the relationships between different variables.

A formula is also an equation that expresses a relationship between two or more variables. The act of finding patterns to describe real-world phenomena is called modeling. A formula models real-world phenomena, meaning that the formula gives a relationship between variables representing real-life situations.

Thus, a complementing statement is “An equation that expresses a relationship between two or more variables, such as $H = \dfrac { 9 } { 10 } ( 220 – a )$ is called $\dfrac { a } { an }$ formula. Process of finding such equations to explain real-world phenomena is called mathematical modeling. Such equations and the meaning assigned to the variables are called mathematical models”.

## Numerical Result

A formula can also be called an equation that expresses a relationship between two or more variables. The act of finding patterns to describe real-world phenomena is called modeling.

A formula models real-world phenomena, meaning that the formula gives a relationship between variables representing real-life situations.

Thus, a complementing statement is “An equation that expresses a relationship between two or more variables, such as $H = \dfrac { 9 } { 10 } ( 220 – a )$ is called $\dfrac { a } { an }$ formula. Process of finding such equations to describe real-world phenomena is called mathematical modeling. Such equations and the meaning assigned to the variables are called mathematical models.”
