what happens to the kinetic energy of the particles in a substance when it is heated
Answer:
Step-by-step explanation:
The kinetic theory of matter can be used to explain how solids, liquids and gases are interchangeable as a result of increase or decrease in heat energy. When an object is heated the motion of the particles increases as the particles become more energetic

Slope = 4.000/2.000 = 2.000
x-intercept = 1/-2 = -0.50000
y-intercept = 1/1 = 1.00000
#2 Slope = 2.000/2.000 = 1.000
x-intercept = 2/-1 = -2.00000
y-intercept = 2/1 = 2.00000
Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

Equation of a Straight Line
1.1 Solve y-2x-1 = 0
Tiger recognizes that we have here an equation of a straight line. Such an equation is usually written y=mx+b ("y=mx+c" in the UK).
"y=mx+b" is the formula of a straight line drawn on Cartesian coordinate system in which "y" is the vertical axis and "x" the horizontal axis.
In this formula :
y tells us how far up the line goes
x tells us how far along
m is the Slope or Gradient i.e. how steep the line is
b is the Y-intercept i.e. where the line crosses the Y axis
The X and Y intercepts and the Slope are called the line properties. We shall now graph the line y-2x-1 = 0 and calculate its properties
Graph of a Straight Line :
Calculate the Y-Intercept :
Notice that when x = 0 the value of y is 1/1 so this line "cuts" the y axis at y= 1.00000
y-intercept = 1/1 = 1.00000
Calculate the X-Intercept :
When y = 0 the value of x is 1/-2 Our line therefore "cuts" the x axis at x=-0.50000
x-intercept = 1/-2 = -0.50000
Calculate the Slope :
Slope is defined as the change in y divided by the change in x. We note that for x=0, the value of y is 1.000 and for x=2.000, the value of y is 5.000. So, for a change of 2.000 in x (The change in x is sometimes referred to as "RUN") we get a change of 5.000 - 1.000 = 4.000 in y. (The change in y is sometimes referred to as "RISE" and the Slope is m = RISE / RUN)
Slope = 4.000/2.000 = 2.000
Geometric figure: Straight Line
Slope = 4.000/2.000 = 2.000
x-intercept = 1/-2 = -0.50000
y-intercept = 1/1 = 1.00000
Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :
y-(x+2)=0

You have budgeted $4,800 for a company to complete guest satisfaction surveys for you. They charge $1,800 + $6 per respondent. How many respondents will you be able receive for the money paid?
Answer:
6
Step-by-step explanation:
There are 500 respondents will you be able receive for the money paid.
What is mean by expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The budgeted for a company to complete guest satisfaction surveys for you is, $4,800.
And, They charge $1,800 + $6 per respondent.
Now,
Let Number of respondents will you be able receive for the money paid is, x
Hence, We can formulate;
⇒ $1800 + $6x = $4800
⇒ 1800 + 6x = 4800
⇒ 6x = 4800 - 1800
⇒ 6x = 3000
⇒ x = 500
Thus, There are 500 respondents will you be able receive for the money paid.

statement: segment HA is parallel to seg HD and seg HD is parallel to seg AN.
Reason: given
statement: angle 1 is congurent to angle 3.
reason: alternate interior angles are congruent.
statement: angles 2 and 4 are congruent
reason: alternate interior angles are congruent.
statement: Seg DA is congruent to seg DA
reason: reflexive property
statement: angle AHD is congruent to angle AND
reason: since angles 1 and 3 are congruent, and 2 and 4 are congruent, and HDA is a triangle, same with AND, the last angle must be congruent.
statement: seg HD is congruent to seg NA and HA is cong to ND.
reason: ASA angle side angle theorem states that if 2 angles and a side is congruent to the corresponding parts of another triangle, then it is congruent.

In the expression 3x - 4y + z, what is the
coefficient of z?
Answer:
1
Step-by-step explanation:
The coefficient is the number in front of a variable. There is a hidden coefficient of 1 in front of z. The reason it is not shown is because any number multiplied by 1 is just that number so showing the 1 is redundant.
The coefficient of z in the expression 3x- 4y +z is 1.
What is expression?A mathematical operation such as subtraction, addition, multiplication, or division is used to combine terms into an expression. In a mathematical expression, the following terms are used:
An absolute numerical number is referred to as a constant.Variable: A symbol without a set value is referred to as a variable.Term: A term can be made up of a single constant, a single variable, or a mix of variables and constants multiplied or divided.Coefficient: In an expression, a coefficient is a number that is multiplied by a variable.Given:
3x - 4y + z
As, we know a coefficient is a number that is multiplied by a variable.
So, the coefficient of x is 3, coefficient of y is 4 and coefficient of z is 1.

Answer:
Three fifths
Step-by-step explanation:
Since 10 was divided by 2 to get 5,
you just do the same to the top half of the fraction.
So when you divide 6 by 2, you get 3.
So it is equal to 3/5, or three fifths.

For every 1 litre of water used 150ml of sucrose and 600ml of saline solution is used
Question:
For every 1 litre of water used to make a medicine, 600 ml of sucrose and 150ml of saline solution are used.
Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.
Answer:
[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]
Step-by-step explanation:
Given
[tex]Water = 1L[/tex]
[tex]Sucrose = 150mL[/tex]
[tex]Saline= 600mL[/tex]
Required
Express as a ratio to the simplest form
First convert the volume of water to mL
[tex]Water = 1L[/tex]
[tex]Water = 1 * 1000mL[/tex]
[tex]Water = 1000mL[/tex]
Express as ratio:
[tex]Water : Sucrose : Saline = 1000mL : 150mL : 600mL[/tex]
[tex]Water : Sucrose : Saline = 1000 : 150 : 600[/tex]
Divide through by 10
[tex]Water : Sucrose : Saline = 100 : 15 : 60[/tex]
Divide through by 5
[tex]Water : Sucrose : Saline = 20 : 3 : 12[/tex]
The ratio can not be further simplified

Solve the following system of equations graphically on the set of axes below.
y = 2x – 2
x +y = 4
Plot two lines by clicking the graph.
Click a line to delete it.
HELP ASAP
Answer: The solution is (2, 2)
Step-by-step explanation:
We have the system of equations:
y = 2*x - 2
x + y = 4
The first step is to write both equations as linear equations in the slope-intercept form.
y = 2*x - 2
y = -x + 4
Now we have two lines, and we can just graph them, the easiest way is the replace the value of x and obtain two points that belong to the line, and then draw a line that passes through both lines.
For example with the first one, we can firt replace x by 0 to get:
y = 2*0 - 2
y = -2
Then the point (0, -2) belongs to this line.
Now we can replace x by 1 to get:
y = 2*1 - 2 = 0
y = 0
The point (1, 0) belongs to this line.
Then we can draw these two points in the graph, and just draw a line that passes through these two points.
Once you have your two lines drawn, the solution of the system will be the point in which the lines intersect.
Below, you can see the two lines graphed (the green is the first one and the red is the second one)
And we can see that they intersect in the point (2, 2)
Then the solution of the system is (2, 2)
