The porosity of the gravel sample is 28.75%
We have to determine.
What is the porosity of the gravel sample?
<h3>The porosity of the gravel sample;</h3>
Porosity is the term which is defined as the volume of voids present in the soil to the total volume of the soil.
The formula used to calculate the Porosity is;

A sponge is a case of a permeable fabric because it incorporates a huge number of purge spaces compared to its volume.
Porosity is the property of a question that communicates the entire volume of purge or pore space within the material.
Hence, the porosity of the gravel sample is 28.75%

<u>Given</u>:
The given equations are
and 
We need to determine the pair of numbers that is a member to the system of equations.
<u>Pair of numbers:</u>
The pair of numbers can be determined by solving the system of equations.
Let us use the substitution method to solve the equations.
Substituting
in the equation
, we have;




Thus, the value of x is 1.
Substituting x = 1 in the equation
, we get;



Thus, the value of y is 7.
Hence, the pair of numbers that is a member of both the equations are (1,7)
Answer:
2
Step-by-step explanation:
to find slope use the equation-
y2-y1 / x2 - x1
then plug in your points
13-7 / 6-3
13-7 = 6
6-3 = 3
6/3 = 2
