Answer:A line segment has two endpoints. It contains these endpoints and all the points of the line between them. ... A ray is a part of a line that has one endpoint and goes on infinitely in only one direction. You cannot measure the length of a ray.
Step-by-step explanation:
We have a line, line segment and ray.
We have to differentiate between the three of them.
State the Dimension of a line?Line along with line segment and ray are all one - dimensional in nature.
A line, line segment, and a ray can be differentiated as follows -
Line - Collection of points in a straight path is called line. It has no endpoint. It does not have any fixed length. The line has length but no width. A line is made up of a set of points that extend infinitely in opposite directions.Line Segment - A line segment is part of a line that has two endpoints and is finite in length. Ray - Ray is a part of the line. It has one endpoint and no fixed length. A ray can be extended infinitely in any one direction. A ray is also called a half-line. We do not measure the length of a ray.Hence - a line, line segment, and a ray is differentiated.

The length of a rectangle is 2 feet less
than three times the width. If the
perimeter is 68 feet, what are the
dimensions of the rectangle?
The length of the rectangle is 25 feet and the width of the rectangle is 9 feet.
It is given that,
Length of a rectangle is 2 feet less than three times the width.Perimeter is 68 feet.Explanation:
Let [tex]x[/tex] be the width of the rectangle. Then the length of the rectangle is [tex]3x-2[/tex].
Perimeter of a rectangle is:
[tex]P=2(\text{length}+\text{width})[/tex]
[tex]68=2(3x-2+x)[/tex]
[tex]68=2(4x-2)[/tex]
[tex]68=8x-4[/tex]
Isolate the variable.
[tex]68+4=8x[/tex]
[tex]\dfrac{72}{8}=x[/tex]
[tex]9=x[/tex]
Now, the length of the rectangle is:
[tex]3(9)-2=27-2[/tex]
[tex]3(9)-2=25[/tex]
Thus, the length of the rectangle is 25 feet and the width of the rectangle is 9 feet.

Does 1/6, -3, V7, -6/5 or 4.5 come first when the numbers are listed from least to greatest? Explain.
Answer:
-3
Step-by-step explanation:
Given numbers:
1/6, -3, √7, -6/5, 4.5
The smallest one is chosen between the two negatives as all the rest are greater.
- 3 is smaller than - 6/5= -1.2 as 3 > 1.2So the answer is -3
Greetings from Brasil...
Let's look at each number
1/6 = 1 ÷ 6 = 0.16666....
- 3 = - 3
√7:
√4 < √7 < √9, so
2 < √7 < 3 the result of √7 is between 2 and 3
-6/5 = (- 6) ÷ 5 or 6 ÷ (- 5) = - 1.2
4.5 = 4.5
Writing the numbers in ascending order can tell:
- 3; - 6/5; 1/6; √7 and 4.5or (same values - approximated values):
- 3; - 1.2; 0.2; 2.5 and 4.5

3x² + 6xy - xy - 2y² (factor the expression) (factor out 2x from the expression)
3x x (x + 2y) -y x (x + 2y) (factor the expression) (factor out x + 2y from the expression)
Solution : (x + 2y) x (3x - y)

Which expression is equivalent to 1.8(2x + 7) - 15?
a 1.2x
b 3.6x - 2.4
0 3.6x - 8
d 16.2x - 15
Answer:
Option B. 1.8(2x + 7) – 15 = 3.6x – 2.4
Step-by-step explanation:
1.8(2x + 7) – 15
To know which option is correct, let us simplify the above expression. This can be obtained as follow:
1.8(2x + 7) – 15
Clear bracket
1.8(2x + 7) – 15 = 3.6x + 12.6 – 15
1.8(2x + 7) – 15 = 3.6x – 2.4
Thus,
1.8(2x + 7) – 15 is equivalent to
3.6x – 2.4

Answer:27/343 or 0.0787172
Step-by-step explanation:
First you need to place the exponent on both the numerator and the demonimator to make 3 to the power of 3 over 7 to the power of 3
Next you evaluate the numerator so 3 to the power of 3 is 27
and 7 to the power of 3 is 343 so your answer in fraction form is 27/343
you can also change into a decimal if you divide the fraction if you need to
Hope this helps
Answer:
[tex](\frac{27}{343})[/tex]
Step-by-step explanation:
This is what you start off with [tex](\frac{3}{7})^{3}[/tex]
[tex](\frac{3}{7})^{3}[/tex] is also equal to [tex](\frac{3}{7})(\frac{3}{7})}(\frac{3}{7})[/tex] because the original equation is [tex](\frac{3}{7})[/tex] multiplied by itself 3 times.
[tex](\frac{3}{7})(\frac{3}{7})}(\frac{3}{7})[/tex]
Multiply the first two fractions straight across
[tex](\frac{9}{49})(\frac{3}{7})[/tex]
Multiply the answer of multiplying the two fractions by [tex](\frac{3}{7})[/tex]
[tex](\frac{27}{343})[/tex]

six students out of 40 students In a class are absent what percentage of the students are absent
15%
Step-by-step explanation:
Absent= 6
Total student = 40
[tex] \frac{6}{40} \times 100 \\ \\ \frac{600}{40} = 15\%[/tex]
Step-by-step explanation:
Hey there!!
We can simply do it.
Here,
Total students =40
Absent students = 6
Now,
[tex]absent\% = \frac{no.asent}{total \: student} \times 100\%[/tex]
Keep all values.
[tex]absent\% = \frac{6}{40} \times 100\%[/tex]
= 15%
Therefore, the absent percentage is 15%.

Change -3x+3y=9 into slope intercept form
To convert to slope-intercept form, we need to get the y by itself.
First add 3x to both sides to get 3y = 3x + 9.
I put the x term first because in slope-intercept form or y = mx + b form,
the x term will always come before the constant term.
Now divide both sides by 3 to get y = x + 3.
Answer:
y = x + 3
Step-by-step explanation:
-3x + 3y = 9
3y = 9 - 3x
/3 /3 /3
y = x + 3
Which is the slope of the line y = -3x +2?
Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - 3x + 2 ← is in slope- intercept form
with slope m = - 3
Answer:
-3.
Step-by-step explanation:
in the form y=mx+b, m is the slope
