Answer:
To calculate the percent of change for your grade, you will need to know your original grade and your revised grade. If you originally got 5 questions right and you checked your work and ended up with 15 questions right, you can calculate the percent of change as follows:
Subtract your original score from your revised score to find the difference: 15 - 5 = 10
Divide the difference by your original score and multiply by 100 to express the change as a percentage: (10 / 5) x 100 = 200%
This means that your grade increased by 200%.

Tell whether each system of equations has no solution, one solution, or infinitely many solutions. Show how you arrived at your conclusion for each.
a. y = 5x + 11 and y = 5x
b. y = 6x + 3 and y = 3x
c. x + 4y = 8 and y = -1/4x + 2
System of equations y = 5x + 11 and y = 5x has no solution, y = 6x + 3 and y = 3x has one solution and x + 4y = 8 and y = -1/4x + 2 no solution.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given system of equations are
a. y = 5x + 11 and y = 5x
Substitute the y value in first equation
5x=5x+11
So the system of equations y = 5x + 11 and y = 5x has no solution.
b. y = 6x + 3 and y = 3x
Substitute the y value in first equation
3x=6x+3
-3x=3
x=-1
y=-3
The system of equations has one solution
c. x + 4y = 8 and y = -1/4x + 2
x+4(-1/4x + 2)=8
x-x+2=8
The system of equations has one solution has no solution
Hence, system of equations y = 5x + 11 and y = 5x has no solution, y = 6x + 3 and y = 3x has one solution and x + 4y = 8 and y = -1/4x + 2 no solution.

what the answer to the math question?
Ling wants to determine the average distance she travels each day in her car. She records the odometer reading, which measures the distance the car has traveled, each morning for a week. What is the mean distance Ling travels each day? Show your work.( Will Mark Brainliest if answer is correct)
Answer: [tex]10,724.28[/tex]
Step-by-step explanation:
Given
Distance traveled on each consecutive day is given as
[tex]10150,10211,10424,10769,10884,11155,11477[/tex]
Mean is given by the sum of the observations divided by the total no of observations.
There are 7 observations in total, so the mean is
[tex]\Rightarrow \mu =\dfrac{10150+10211+10424+10769+10884+11155+11477}{7}\\\\\Rightarrow \mu=\dfrac{75,070}{7}\\\\\Rightarrow \mu =10,724.28[/tex]
thus, the mean is [tex]10,724.28[/tex]
The mean distance Ling travels each day is [tex]10724.28 \: \rm miles[/tex] approximately.
How to find the mean value of a data set?The mean value of the data set is the ratio of sum of data set's values to number of values it has.
If the data set consists of values [tex]x_1, x_2, ..., x_n[/tex], then we get the mean value as:
[tex]\overline{x} = \dfrac{x_1 + x_2 + \cdots + x_n}{n}[/tex]
For this case, we have to find the average distance(in miles) from the distance Ling traveled for 7 days.
Thus, we get the average distance he traveled as:
[tex]\overline{d} = \dfrac{10150 + 10211 + 10424 + 10769 + 10884 + 11155 + 11477 }{7}\\\\\overline{d} = \dfrac{75070}{7} \approx 10724.28 \: \rm miles[/tex]
Thus, the mean distance Ling travels each day is [tex]10724.28 \: \rm miles[/tex] approximately.

B)

7
Answer:
x = 6
Step-by-step explanation:
4(x + 4) = 5(3 + 5) => Intersecting Secants Theorem
4(x + 4) = 5(8)
Open the bracket
4x + 16 = 40
Subtract 16 from each side
4x + 16 - 16 = 40 - 16
4x = 24
4x/4 = 24/4
x = 6
The length of the segment x is 6
The length of the segment x is calculated using the Intersecting Secants Theorem
This is represented as:
[tex]4(x + 4) = 5(3 + 5)[/tex]
Evaluate 3 + 5
[tex]4(x + 4) = 5(8)[/tex]
Open brackets
[tex]4x + 16 = 40[/tex]
Collect like terms
[tex]4x = 40 - 16[/tex]
Evaluate the like terms
[tex]4x = 24[/tex]
Divide both sides by 4
[tex]x = 6[/tex]
Hence, the length of the segment x is 6

Hot dogs and corndogs were sold at last night's football game. A total of 81 were sold which allowed the concession stand to bring in $201. How many of each were sold?
The total number of corn dogs sold is 28 corn dogs and number of hotdogs is 53
What is total cost?Total cost is the overall expense incurred for a particular product, service, or project. It includes both fixed and variable costs, such as materials, labor, and overhead. It is often used in business and economic analysis as a measure of the efficiency and profitability of a particular venture. The total cost of a product or service can also be used to set prices and make pricing decisions.
According to question:-
step1
h = number of hotdogs
c = number of corndogs.
cost of hotdog = $3
corn dog = $1.50
The equation:
3h + 1.50c = 201 (1)
h = 2c - 3 (2)
step2
substitute (2) into (1)
3(2c - 3) + 1.50c = 201
6c - 9 + 1.50c = 201
7.50c - 9 = 201
7.50c = 201 + 9
7.50c = 210
c = 210/7.50
c = 28
Therefore,
h = 2c - 3
= 2(28) - 3
= 56 - 3
= 53

A bomber aircraft on take-off carries twelve dozen bombs, each weighing ten kilos; the aircraft takes off for Warsaw, the international center of Jews. It bombs the town. On take-off with all the bombs on board and a fuel tank containing 1000 kilos of fuel, the aircraft weighed about eight tons. When it returns from the crusade, there are still 230 kilos of fuel left. What is the weight of the aircraft when empty?
Answer:
The aircraft when empty weighs 4,817.48 kilograms.
Step-by-step explanation:
Since a bomber aircraft on take-off carries twelve dozen bombs, each weighing ten kilos; and the aircraft takes off for Warsaw, the international center of Jews bombing the town, and on take-off with all the bombs on board and a fuel tank containing 1000 kilos of fuel, the aircraft weighed about eight tons, while when it returns from the crusade, there are still 230 kilos of fuel left, to determine what is the weight of the aircraft when empty, the following calculation must be performed:
1 ton = 907.185 kg
8 x 907.185 = 7,257.48
7,257.48 - (12x12x10) - 1000 = X
7,257.48 - 1,440 - 1000 = X
7,257.48 - 2,440 = X
4,817.48 = X
Therefore, the aircraft when empty weighs 4,817.48 kilograms.

Hexagon DEFGHI is translated on the coordinate plane below to create hexagon D′E′F′G′H′I′: Hexagon DEFGHI and Hexagon D prime E prime F prime G prime H prime I prime on the coordinate plane with ordered pairs at D 2, 5, at E 5, 5, at F 6, 3, at G 5, 1, at H 2, 1, at I 1, 3, at D prime negative 6, negative 2, at E prime negative 3, negative 2, at F prime negative 2, negative 4, at G prime negative 3, negative 6, at H prime negative 6, negative 6, at I prime negative 7, negative 4
Answer: To find the image of a figure under a translation, you need to apply the same translation to every point in the figure.
In this case, the image of hexagon DEFGHI is hexagon D′E′F′G′H′I′. To find the image of each point, you can apply the translation that maps point D to point D′.
For example, to find the image of point E under the translation, you can apply the same translation that maps point D to point D′:
Point D is located at (2, 5).
Point D′ is located at (-6, -2).
The translation that maps point D to point D′ is a translation 6 units to the left and 2 units down.
To find the image of point E under this translation, you can apply the same translation to point E:
Point E is located at (5, 5).
The image of point E is located at (5 - 6, 5 - 2) = (-1, 3).
You can follow the same process to find the images of the other points under the translation.
Alternatively, you can use the coordinates of point D and point D′ to find the translation vector that describes the translation. The translation vector is a displacement that describes the change in position of a point under the translation.
In this case, the translation vector is given by the displacement from point D to point D′:
Point D is located at (2, 5).
Point D′ is located at (-6, -2).
The translation vector is given by the displacement (-6 - 2, -2 - 5) = (-8, -7).
To find the image of any point under the translation, you can add the translation vector to the coordinates of the point. For example, to find the image of point E under the translation, you can add the translation vector to the coordinates of point E:
Point E is located at (5, 5).
The translation vector is (-8, -7).
The image of point E is located at (5 - 8, 5 - 7) = (-3, -2).
You can follow the same process to find the images of the other points under the translation.
