Answer:
Proper fractions with a denominator of 6: 1/6, 2/6, 3/6, 4/6, 5/6.
Step-by-step explanation:
A proper fraction means that the numerator is less than the denominator.
Examples of this are 1/3, 3/4, 2/7.
Since the denominator must be 6, hence the answers are 1/6, 2/6, 3/6, 4/6, 5/6.
We know that the number line is in 12ths. In addition, we know that 6ths are 1/2 of 12. Thus, we put a proper fraction on every other line on the number line.

Answer:
x=57
Step-by-step explanation:
Since the angles 'x' and '2x+7' add up to a supplementary angle (straight line)
we can then say;
[tex]x + 2x + 9 = 180[/tex]
[tex]3x = 180 - 9[/tex]
[tex]3x = 171[/tex]
[tex]x = \frac{171}{3} = 57[/tex]
Answer:
I think 57
Step-by-step explanation:
x+2x+9=180
3x+9=180
3x=180-9
3x=171
x=57

At a concert , tickets cost either $40 or $60. 700 tickets were sold at a cost of $33600, find how many $40 tickets were sold
Answer:
420 $40 tickets.
Step-by-step explanation:
Here is the explanation.
1. As 700 tickets cost a total of $33600, the average cost of each ticket is $48.
2. As there are 700 total tickets with each costing $40 or $60, we can use the total cost ($33600) to define the amount of each ticket.
3. If there were to be 420 $40 tickets, there will be 280 $60 tickets.
4. This means that the cost of each price of tickets ($40 and $60) will be distributed evenly among the total price, each costing $16800.
5. 420 x 40=16800 280x60=16800
6. There are 420 $40 tickets sold at the concert.

The admission fee at an amusement park is $1.50 for children and $4 for adults. On a certain day, 301 people entered the park, and the admission fees collected totaled 814 dollars. How many children and how many adults were admitted? Your answer is number of children equals number of adults equals
Answer:
156 children145 adultsStep-by-step explanation:
Let number of adults be a and children be c
Then we have equations
a + c = 3014a + 1.5c = 814From the first equation we get a = 301 - c, we substitute a in the second equation:
4(301 -c) + 1.5c = 8141204 - 4c + 1.5c = 8142.5c = 1204 - 8142.5c = 390c = 390/2.5c = 156Then finding the value of a:
a = 301 - 156 = 145is 14/20 and 16/24 equal (yes or no?)

Theorem used
Tangents drawn from a exterior point of a circle have equal length.
According to the question,
As shown in the diagram,
P, Q, R, and S are exterior points of a circle through which tangents are drawn.
Given,
Length of tangent PA = 13cm
Length of tangent SA= 9cm
Length of tangent RC = 4cm
Length of tangent QC =6cm
As per stated theorem we get,
Length of tangent PB = 13cm
Length of tangent SD 9cm
Length of tangent RD = 4cm
Length of tangent QB =6cm
Perimeter of a given polygon = 13 +13 +9+9+4+4+6+6

What is the surface area of the triangular prism?
What is the volume of the triangular prism?

Surface Area:
A triangular prism is made up of 3 rectangles and 2 triangles.
Area of a rectangle = base x height
Area of a triangle = 1/2 x base x height
Rectangle: 5.6 x 2.7 = 15.12
All 3 rectangles: 15.12 x 3 = 45.36
Triangle: 1/2 x 2.7 x 2.3 = 3.105
Both triangles: 3.105 x 2 = 6.21
Surface Area: 45.36 + 6.21 = 51.57 mm^2

Suppose Bobby's cat and dog were 6 miles apart after 30 minutes. Write an equation to
Answer:
3x/2 =6
Step-by-step explanation:
The distance between the dog and cat is 6 miles. Then the equation is 30x = 6 or x = 0.2.
What is speed?The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity. It is the ratio of distance to time.
We know that the speed formula
[tex]\rm Speed = \dfrac{Distance}{ Time }[/tex]
Bobby's cat runs at x mph. Bobby's dog runs twice as fast as his cat.
The speed of a cat is x. Then the speed of the dog is 2x.
The distance traveled by the cat in 30 minutes will be
[tex]\rm D_c = 30 \times x\\\\D_c = 30 \ x[/tex]
The distance traveled by the dog in 30 minutes will be
[tex]\rm D_d = 30 \times 2x\\\\D_d = 60 \ x[/tex]
Suppose Bobby's cat and dog were 6 miles apart after 30 minutes.

Answer:

Step-by-step explanation:
THIS IS THE COMPLETE QUESTION BELOW:
Karen has a red ribbon that is 18 feet long and a blue ribbon that is 12 feet long. She wants to cut both ribbons into pieces that are all the same length and she wants no ribbon leftover when she is done. What is the greatest length in feet, of each piece of ribbon that she can cut?
Here the question is only talking about the GREATEST COMMON FACTOR that exist between 12 and 18. Since we are told that She wants to cut both ribbons into pieces that are all the "THE SAME LENGHTH"
For the ribbon that of 18 feet long, it can only be cut into 3pieces of equal Lenght i.e(18/6)= 3 pieces
For the ribbon that of 12 feet long, it can only be cut into 2pieces of equal Lenght i.e(12/6)= 3 pieces
Therefore the greatest common factor which divide both 12 and 8 is 6. which means 6 is the greatest length in feet, of each piece of ribbon that she can cut

Create a line segment that is exactly 10 units in length and has a midpoint of (-3,4)
Answer: A segment AB with Endpoints A (-8, 4) and B (2,4) is a horizontal line segment with (-3,4) as the midpoint.
A segment CD with endpoints C(-3,9) and D(-3,-1) will create a vertical line segment with (-3,4) as the midpoint.
A line segment FG with endpoints F (-6,0) and G(0,8) is a diagonal line with a slope of 4/3 and its midpoint is (-3,4)
Step-by-step explanation: For a horizontal or vertical line segment, choose the x-value or the y value of the midpoint. subtract 5 to get the lower endpoint, add 5 to get the higher endpoint. Keep the other coordinate the same.
The diagonal line segment is based on the hypotenuse of a triangle with side lengths corresponding to the Pythagorean Triple 3,4,5 Add and subtract 3 to the x-value od the midpoint, add and subtract 4 to the y value of the midpoint and the hypotenuses will extend 5 units in both directions from the midpoint.
