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.

20 is 80 percent of what number?
Answer:
20 is 80 of 25
Explanation:
20x10/8=25
A percentage is a way to describe a part of a whole. 20 is 80% of 25.
What are Percentages?A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.
To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.
Let the number be x. Therefore, we can write,
80% of x = 20
0.80 × x = 20
x = 20/0.8
x = 25
Hence, 20 is 80% of 25.

History of algebra
Algebra can essentially be considered as doing computations similar to those of arithmetic but with non-numerical mathematical objects. However, until the 19th century, algebra consisted essentially of the theory of equations. For example, the fundamental theorem of algebra belongs to the theory of equations and is not, nowadays, considered as belonging to algebra (in fact, every proof must use the completeness of the real numbers, which is not an algebraic property).
This article describes the history of the theory of equations, called here "algebra", from the origins to the emergence of algebra as a separate area of mathematics.
Given that KB = 28, what is the measure of angle KBL and segment KA
Answer:
KA = 28
∠KBL = 90°
Step-by-step explanation:
KA = KB (both are radii)
KB = 28, so KA = 28
∠KBL = 90° because tangents are perpendicular to the radius

Which statement is true about the data sets of two sets of quiz scores?
Sample A: 5, 5, 5, 5, 5 Sample B: 2, 2, 2, 2, 17
Select one:
Samples A and B have the same mean, but Sample A has a smaller median than Sample B.
Samples A and B have the same median, but Sample A has a larger mean than Sample B.
Samples A and B have the same median, but Sample A has a smaller mean than Sample B.
Samples A and B have the same mean, but Sample A has a larger median than Sample B.
Answer: Samples A and B have the same mean, but Sample A has a larger median then Sample B.
Step-by-step explanation:
The median is the middle number in the sequence.
To find the median, place the numbers in order. Then take away, or cross out, one number from each side. Keep going until you are down to one or two numbers. If there is only one number left, that’s your median. If two, add the numbers together and divide by 2.
The mean is the average. To get the mean you add up all the values and subtract that sum by how many numbers there are in the sequence.
Option D is correct for the given conditions, Samples A and B have the same mean, but Sample A has a larger median than Sample B.
What are measures of central tendency?The descriptive summary of a data set is known as the central tendency in statistics. It reflects the center of the data distribution through the use of a single number from the dataset. Additionally, it only provides a summary of the dataset rather than information on specific data within the dataset. In general, several statistical metrics can be used to determine a dataset's central tendency.
Given the data sets of two sets of quiz scores,
Sample A = 5, 5, 5, 5, 5
sample B = 2, 2, 2, 2, 17
mean is the average of total samples,
mean of sample A = (5 + 5+ 5 + 5 + 5 )/5
mean of sample A = 5
Mean of sample B = (2 + 2 + 2+ 2 + 17)/5
mean of sample B = 5
since the mean of both sample are same,
median is the central digit of sets
median of A is 5 and the median of B is 2,
so the median of sample A is larger than sample B.
Hence option D is correct.

add 4x both sides
y=4x+9
insert into y=2x+1
2x+1=4x+9
subtract 1 both sides
2x=4x+8
subtract 4x both sides

You need to fence in a rectangular piece of land for your dog to run and play. The length is 3 times the width. If the perimeter is 120 ft, what are the dimensions of your very own dog park?
Answer:
Width = 15 feet
Length = 45 feet
Step-by-step explanation:
You need to fence in a rectangular piece of land for your dog to run and play. The length is 3 times the width. If the perimeter is 120 ft, what are the dimensions of your very own dog park?
Perimeter of a rectangle = 2L + 2W
The length is 3 times the width.
L = Length = 3W
W = Width
P = 120 ft
Hence:
120 = 2L + 2W
120 = 2(3W) + 2W
120 = 6W + 2W
120 = 8W
W = 120/8
W = 15 feet
Solving for Length
L = 3W
L = 3 × 15 feet
L = 45 feet
Therefore, the dimensions of your very own dog park is
Width = 15 feet
Length = 45 feet

CDE is reflected over the Y- Axis
Answer:
The answer to this question is A
The new coordinates will be C( 3 ,0), D( 7,1) , E(2,4) , Option A is the correct answer.
What is the meaning of Reflection ?When a object or a figure is reflected , it means an mirror image if the object is being created , the shape and size of the object remains same , Only the coordinates change on the basis of the axis used for Reflection.
The figure is given in the question.
The coordinates of the figure is
C( -3 ,0)
D( -7,1)
E(-2,4)
When reflection is done along any axis , the coordinates of the other axis change sign.
so in this case ( x,y ) -----> ( -x,y)
The new coordinates will be
C( 3 ,0)
D( 7,1)
E(2,4)
Therefore Option A is the correct answer.

Given the point and its image, determine the scale factor. B(2,5) B'(1,2.5) 0 -1/2 02 0-2 O 1/2
Given:
The point is B(2,5) and its image is B'(1,2.5).
To find:
The scale factor.
Solution:
If a figure is dilated by the scale factor k and (0,0) is the center of then the scale factor is defined as
[tex]k=\dfrac{\text{x-coordinate of the point on image}}{\text{x-coordinate of the corresponding point on the original figure}}[/tex]
x-coordinate of point B' is 1 and the x-coordinate of point B is 2. So, the scale factor is
[tex]k=\dfrac{1}{2}[/tex]
Therefore, the scale factor is [tex]\dfrac{1}{2}[/tex] and the correct option is D.
