What is the difference between a line, line segment, and a ray?
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.

Answer:
x= -12
Step-by-step explanation:
3(x+7)+6= -9
3x+21+6= -9
subtract 6 from both sides that gives you your equation that you can work with.
3x+21= -15
then subtract 21 from both sides that gives you

Simplify these ratios.
(a) 1.8 kg : 600 grams
(b)
1 hour 20 minutes : 30 minutes
Answer:
a) 3 :1
b)8 : 3
Step-by-step explanation:
When finding ratio's, both should be in same units.
1.8 kg = 1.8 * 1000
= 1800.0 grams
1.8 : 600 = 1800 : 600 = 18 : 6
= 3 : 1
b) 1 hour 20 minutes = 60 + 20 = 80 minutes
1 hour 20 minutes : 30 minutes = 80 : 30
= 8 : 3
Answer:
a. 3grams : 1gram b. 8 minutes : 3 minutes
Step-by-step explanation:
1.8kg is the same as 1800 grams.
1800:600 is the same as 3:1.
1 hour 20 minutes is the same as 80 minutes.
80:30 is the same as 8:3.

find the distance between the points (-3,10) and (9,-6)
Answer:
20
Step-by-step explanation:
The distance formula is:
[tex]d = \sqrt {\left( {x_1 - x_2 } \right)^2 + \left( {y_1 - y_2 } \right)^2 }[/tex]
where (x₁, y₁) and (x₂, y₂) are the points. We are given the points (-3,10) and (9,-6). Therefore,
[tex]x_{1}=-3 \\y_{1}= 10\\x_{2}=9 \\y_{2}=-6[/tex]
Substitute the values into the formula.
[tex]d = \sqrt {\left( {-3 - 9} \right)^2 + \left( {10- -6} \right)^2 }[/tex]
[tex]d = \sqrt {\left( {-3 - 9} \right)^2 + \left( {10+6} \right)^2 }[/tex]
Solve inside the parentheses. Subtract 9 from 3. Add 10 and 6.
[tex]d = \sqrt {\left( {-12} \right)^2 + \left( {16} \right)^2 }[/tex]
Evaluate the exponents.
⇒ -12²= -12*-12= 144
[tex]d = \sqrt {\left144 + \left( {16} \right)^2 }[/tex]
⇒ 16²= 16*16=256
[tex]d = \sqrt {\left144 + \left256}[/tex]
Add 144 and 256.
[tex]d=\sqrt{400}[/tex]
Take the square root of 400.
[tex]d=20[/tex]
The distance between the two points is 20.

Answer:
A(2, 6) and C(2, -6)
Step-by-step explanation:
The distance between any two points is given by :
Given vertices : A(2, 6), B(6, 0), C(2, -6) and D(-4, 0)
Since, points A and C has the largest distance between them.
Therefore, the points A and C are the farthest points.
A gym membership is $100 sign-up fee and charges $20 a month thereafter. How much is the membership fee in a month?
Answer:
$120
Step-by-step explanation:
y = mx + b
The $100 sign up fee is a set amount, or the b value.
The $20 would be the m value since it the constant change, or the slope.
Thus, the equation would be y=20x + 100
The membership fee for 1 month would be --->
y= 20(1) +100
y= 20 + 100
y= $120

The diagram shows a circle inside a square.
a
16 cm
Work out the area of the circle.
Answer:
Side of square=Diameter of circle=16
Radius= Diameter/2=16/2=8
Area of circle=4Πr²
=4*3.14*8²
=803.84cm²
The area of the circle that is formed inside the square will be 200.96 square cm.
What is the area of the circle?It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
Let r be the radius of the circle. Then the area of the circle will be
A = πr² square units
The length of the square is 16 cm.
From the diagram, the length of the square is equal to twice the radius of the circle. Then we have
2r = a
2r = 16
r = 8 cm
The area of the circle is given as,
A = π (8)²
A = 3.14 × 64
A = 200.96 square centimeters
The region of the circle that is framed inside the square will be 200.96 square cm.

Nikki is building a wall with bricks. Each brick is 10 inches long. The bricks are laid end-to-end, and one inch of mortar is layered between each brick.
a. Write and equation to model the number of bricks, N, Nikki needs in each layer to build a wall 10 feet long.
b. Solve the equation and state your result in words.
Answer:
b = 11
11 bricks will be required with 10 (1 inch motar) in between the bricks.
Step-by-step explanation:
Given the following :
Length of brick = 10 inches long
Between each laid brick, there is an inch of mortar layered before the next brick.
Number of bricks needed to build a wall which is 10 feets long.
Converting from feet to inch :
1 foot = 12 inches
Hence,
10 feets = (10 × 12) = 120 inches (length of wall).
Hence number of bricks needed in each layer :
Total length of b, bricks = length per brick × b = 10b
Since mortar is laid in between any two bricks, then length of mortar for b, number of bricks will be (b-1) inches
Since the total length of wall to be constructed is 120 inches ;
Then the equation required =
Sum of brick length + mortar = 120 inches
10 b + (b - 1) = 120
11b - 1 = 120
Hence,
11b = 120 + 1
11b = 121
b = 121 / 11
b = 11
Number of mortar = (b - 1) = - 11 - 1 = 10
Hence, 11 bricks will be required with 10 (1 inch motar) in between the bricks.
Simplify (5x−2+3x^2)+(4x+3)
Answer:
3x^2 + 9x + 1
Or
3x ( x + 3 ) + 1
Step-by-step explanation:
(5x - 2 +3x^2 ) + (4x + 3 )
To make this a little bit more easier to read, you can remove the parentheses:
5x - 2 + 3x^2 + 4x + 3
Now, write in a way so that the like terms are next to each other:
3x^2 + 5x + 4x - 2 + 3
Now simplify the 'x' terms to get:
3x^2 + 9x - 2 + 3
Now, simplify the integers (the ones with now variables with them) to get:
3x^2 + 9x + 1
If you want, you can factor out the 3x for two of the terms to get :
3x ( x + 3 ) + 1
Therefore, your simplest form can either be 3x^2 + 9x + 1 OR 3x (x + 3 ) + 1
