Formula Explained

The calculation follows this formula:

Result = (Value1 × Weight1) + (Value2 × Weight2) + (Value3 × Weight3)

Where:

Value1 = 30
Weight1 = 0.6
Value2 = 0.6
Weight2 = 0.2
Value3 = 20
Weight3 = 0.2

This formula is commonly used in weighted average calculations, physics problems, and engineering applications.

Worked Example

Let's compute the expression 30 × 0.6 + 0.6 × 0.2 + 20 × 0.2:

First term: 30 × 0.6 = 18
Second term: 0.6 × 0.2 = 0.12
Third term: 20 × 0.2 = 4
Sum: 18 + 0.12 + 4 = 22.12

The final result is 22.12.

Interpreting Results

The result represents the combined weighted value of the inputs. This is useful in:

Physics calculations involving multiple weighted components
Engineering design where different factors contribute differently
Statistical analysis of weighted averages

Note: The result is sensitive to the weights you assign. Ensure your weights accurately represent the relative importance of each value.
