Answer:
Permeabilidad
Step-by-step explanation:
La permeabilidad es la medida de la capacidad o facilidad con la que un medio o material poroso permite el paso o la penetración de un fluido (líquido o gas) a través de él.
Un material altamente permeable como la grava permite que el fluido fluya a través de él fácilmente con poca restricción, de modo que prácticamente todo el fluido tiene el potencial de fluir a través de una columna de grava.
Un material poco permeable como la arcilla impide o restringe el flujo de fluido a través de él.
La permeabilidad se mide en un laboratorio utilizando muestras centrales de un material.
La unidad de permeabilidad es m²

In the diagram, the measure of angle 3 is 76°.
A transversal intersects 2 lines to form 8 angles. Clockwise from top left, the angles are 1, 2, 3, 4; 5, 6, 7, 8.
What is the measure of angle 4?
Answer:
Alright, lets get started.
Angle 3 and angle 4 are adjacent angles because they are having the common side.
They both are on straight line, so, their addition will be 180°.
Suppose angle 4 is x , hence
angle 4 + angle 3 = 180
Subtracting 89 from both sides
°
Hence angle 4 is 91°. : Answer
Hope it will help :)

Answer:
91 degrees

Solve the problem by entering and solving an equation.
A rectangular picture frame has a perimeter of 58 inches. The height of the frame is 12 inches. What is the width of the frame
Answer:
15 inches
Step-by-step explanation:
Substitute the formula
Let 'x' be the other side
2 [ l + b ] = Perimeter
2 [ 12 + x ] = 58
12 + x = 58 divided by 2
x = 27 - 12
= 15
Therefore 15 inches is the other side.

In Three gallons there are 64 cups. if 5 cups makes 10 servings, that is 1/2 cup per serving. So 64 cups will make 128 servings.
Anyone can help me solve this equation using cross multiplying
9514 1404 393
Answer:
x = 1 or 5
Step-by-step explanation:
The notion of "cross-multiplying" is the idea that the numerator on the left is multiplied by the denominator on the right, and the numerator on the right is multiplied by the denominator on the left. This looks like ...
[tex]\displaystyle \frac{x-1}{7}=\frac{2x-2}{3x-1}\ \longrightarrow\ (x-1)(3x-1)=(7)(2x-2)[/tex]
Then the solution proceeds by eliminating parentheses, and solving the resulting quadratic equation.
[tex]3x^2-4x+1=14x-14\\\\3x^2-18x+15=0\qquad\text{subtract $14x-14$}\\\\x^2-6x+5=0 \qquad\text{divide by 3}\\\\(x-1)(x-5)=0\qquad\text{factor}\\\\x\in\{1,5\}[/tex]

Comment on "cross multiply"
Like a lot of instructions in Algebra courses, the idea of "cross multiply" describes what the result looks like. It doesn't adequately describe how you get there. The one and only rule in solving Algebra problems is "whatever is done to one side of the equation must also be done to the other side of the equation." If you multiply one side by one thing and the other side by a different thing, you are violating this rule.
What looks like "cross multiply" is really "multiply by the product of the denominators and cancel like terms from numerator and denominator." Here's what that looks like with the intermediate steps added.
[tex]\displaystyle \frac{x-1}{7}=\frac{2x-2}{3x-1}\\\\\frac{x-1}{7}\times7(3x-1)=\frac{2x-2}{3x-1}\times7(3x-1)\\\\(x-1)(3x-1)=(2x-2)(7)\qquad\textit{looks like}\text{ cross multiply}[/tex]

Which expression represents the ratio of the difference of the two means to Sidney's mean absolute deviation
Answer:
The ratio of the difference of the two means to Sidney's mean absolute deviation = [tex]\frac{4}{3.28}[/tex] = 1.2195
Step-by-step explanation:
P.S - The exact question is -
Given - The means and mean absolute deviations of Sidney’s and Phil’s grades are shown in the table below.
Sidney’s Grades Phil’s Grades
Mean 82 78
Mean Absolute Deviation 3.28 3.96
To find - Which expression represents the ratio of the difference of the two means to Sidney’s mean absolute deviation?
Proof -
Given that Mean of Sidney Grades = 82
Mean of Phil's Grades = 78
So,
The difference of two means = 82 - 78 = 4
Also,
Given, Mean Absolute Deviation of Sydney = 3.28
Now,
The ratio of the difference of the two means to Sidney's mean absolute deviation = [tex]\frac{4}{3.28}[/tex] = 1.2195

Answer:
Sure.
Step-by-step explanation:
So X is a variable meaning its a letter that represents a number. When there are a number and a variable (or a letter) like this 2x or 9y it means you are going to multiply the number by the variable. In this case it is 7 times x is equal to 21 so all we have to do is find what times 7 is equal to 21 and that number is 3. So if 7*x=21 is 7*3=21 then x=3. If you have any questions ill be more than open to answering them, hopefully this helped. Have a good day/night.

Of Linear Eqitions by
Elimination
3x-y=0
2x+y=-10
Answer:
(-2, -6)
Step-by-step explanation:
Given the simultaneous equation
3x-y=0 ... 1
2x+y=-10 ... 2
Add both equations to eliminate y
3x + 2x = 0 - 10
5x = -10
x = -10/5
x = -2
Substitute x = -2 into 1
3(-2)- y = 0
-6 - y = 0
-y = 0+ 6
-y = 6
y = -6
Hence the coordinate (x, y) is (-2, -6)

Fill in the empty slots by dragging tiles from the left to show the next step for solving the equation. Solve the equation 1.2x = 5.16 for x X=
Answer:
x = 4.3
Step-by-step explanation:
Given the question :
Fill in the empty slots by dragging tiles from the left to show the next step for solving the equation. Solve the equation 1.2x = 5.16 for x X=
Taking out the equation :
1.2x = 5.16
Divudse both sides by 1.2
1.2x/1.2 = 5.16 / 1.2
x = 4.3
Hence, x = 4.3
The value of x in the equation is equal to 4.3
Data;
1.2x = 5.16Linear EquationTo solve this problem, we need to first make x the subject of formula and this is done by dividing both sides of coefficient of x.
[tex]\frac{1.2x}{1.2} = \frac{5.16}{1.2}[/tex]
This can be further simplified as
[tex]x = \frac{5.16}{1.2} = 4.3[/tex]
The value of x in the equation is equal to 4.3

The answer is 600
Step-by-step explanation:
Multiply 6 by 1000, and 10 by x.
The equation would be 6000=10x.
Now, just solve for x by dividing by 10 which equals to 600.
Find the quotient
6 1/2 divided by 3/4
Answer:
8 2/3
Step-by-step explanation:
First, we turn 6 1/2 into an improper fraction, which is 13/2. Now, we can write this out as: 13/2 divided by 3/4. When dividing fractions, you reverse the sign to multiplication and you flip the numerator and the denominator of the second number. So, in this case, it would be 13/2 TIMES 4/3 which now we can do! 13*4 is 52 and 2*3 is 6. 52/6 is a number we can simplify. We can divide out a 2, so 52/2 is 26 and 6/2 is 3. 26/3 can be put into a mixed number. 3 goes into 26, 8 times and there is a 2 left over. So our final answer is 6 2/3.
