Answer:

$3 * 18= 54$ and $54/18 = 3$

Step-by-step explanation:

Given

$Sections = 3$

$Measurement=18$ per section

$Total\ Measurement=54$

Required

Model the scenario

The model of this scenario is:

$Sections * Measurement = Total\ Measurements$

This gives:

<em /> $3 * 18 = 54$ <em> -- This represents the multiplication model</em>

Divide both sides by 18

$3 * 18/18 = 54/18$

$3 * 1 = 54/18$

$3 = 54/18$

Reorder

<em /> $54/18 = 3$ <em> -- This represents the division model</em>

If a bloodstain has a length of 3.0cm and a width of 1.5cm what is the angle of impact?

zalisa [80]

The angle of impact is 30°

<h3>What is the angle of impact?</h3>

In a bloodstain, the angle of impact can be used to determine the appearance of the resulting bloodstain if the bloodstain has a tail or pattern.

Bloodstain pattern analysis is the study of bloodstains at a scene of the crime in an attempt to reconstruct the events that resulted in the bloodshed.

Mathematically;

$\mathbf{Angle \ of \ impact = sin^{-1} (\dfrac{width \ stain}{length \ stain} )}$
