Answer:

None of the above unless the equations have a typo

Step-by-step explanation:

With (0,-2), the x is 0. Plug that in on all equations and see which result in -2 as y. Since all of them do, try the next pair

(4,-1). Now plug 4 in to all the equations.

y=4*4-2 -- y=16-2=14

y=-4*4-2 -- y=-16-2=-18

y=2*4-2 -- y=8-2=4

y=-3*4-2 -- y=-12-2=-14

Neither apply

The Coffee Counter charges $8 per pound for Kenyan French Roast coffee and $7 per pound for Sumatran coffee.

spayn [35]

Answer:

Kenyan French Roast coffee x=6

Sumatran coffee y=14

Step-by-step explanation:

x+y=20 blend coffee

8x+7y=7.3(20) selling price

x+y=20 ⇒ x=20-y

substitute in the equation:

8x+7y=7.3(20)

8(20-y)+7y=7.3(20) for 20 pound blend

160-8y+7y=146

-y=146-160

y=14 pond

x+y=20

x=20-14=6

check : 14*7+6(8)=146/7.3=20 pound

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;

$\rm Porosity =\dfrac{Volume \ of \ voids \ present \ in soil}{Volume \ of \ soil}$

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%
