Answer:

41 Degrees

Step-by-step explanation:

So basically you add the 72 and the other 72 to get 148.You obviously know the angle in between 72 and 72 is a right angle or 90 degrees.Then you add 148 and 90 to get 238.Then 360 - 238 is 122.Now you know all the angles.So we have to ask ourselves what is 148/360 simplified.It is 37/90.Now that we know that and we know that the radius is 10.We have to find the regular area which is 10 times 10 which is 100.Finally we need to figure out what part of 100 is 37/90 and it is 41.111111111111.Rounded it is 41.

Answer:

Consider the system of equations, x – 2y = 8 and –2x + 4y = –16.

What is x – 2y = 8 in slope-intercept form?

y=(1/2)x - 4

What is –2x + 4y = –16 in slope-intercept form?

y=(1/2)x - 4

How many solutions will there be?

infinitely many solutions

What will the graph of the system look like?

the lines are exactly the same

(I answered using the other answer and it was incorrect. It autocorrected it to these answers. This answer is correct.)

Slope intercept form of the equation

[tex]x - 2y = 8 \\ y=\frac{1}{2}x-4[/tex]

Slope intercept form of the equation

[tex]-2x+4y=-16 \\y=\frac{1}{2}x-4[/tex]

Solution is infinite

Graph of the system are the lines that lies one above the other.

Given :

System of equations

[tex]x - 2y = 8 \\ -2x+4y=-16[/tex]

slope intercept form of the equation is y=mx+b

Lets solve each equation for y

[tex]x - 2y = 8 \\-2y=-x+8\\y=\frac{1}{2}x-4[/tex]

Slope intercept form of the equation

[tex]x - 2y = 8 \\ y=\frac{1}{2}x-4[/tex]

Lets solve the second equation for y

Slope intercept form of the equation

[tex]-2x+4y=-16\\4y=2x-16\\y=\frac{1}{2}x-4[/tex]

The slope intercept form of both the equations are same

So there are infinite solutions for the given system of equations.

When the solution is infinite then the graph of equation are the lines that lies one above the other .

Ben's weekly unemployment compensation is $956.15

A percentage is a number or ratio expressed as a fraction of 100. It is generally denoted using the percent sign ''%''.

Now it is given that,

Weekly unemployment compensation = 55%

Ben earned a total in July, August, and September = $22,400

And in October, November, and December = $22,800

Therefore, his total compensation for the six month period = $22,400 + $22,800 = $45,200

his average weekly salary = $45,200 / 26 weeks = $1,738.46

Ben's unemployment compensation = $1,738.46 x 55% = $956.15

Hence,Ben's weekly unemployment compensation is $956.15

Answer:

knife = £5.52

Step-by-step explanation:

The 2 equations are

k = 3s → (1)

9s + 12k = 82.8 → (2)

Substitute k = 3s into (2)

9s + 12(3s) = 82.8

9s + 36s = 82.8

45s = 82.8 ( divide both sides by 45 )

s = 1.84

Substitute s = 1.84 into (1)

k = 3 × 1.84 = 5.52

Step-by-step explanation:

The question is about the congruency of two triangles DEF and XZY. A Congruence Theorem (SSS, SAS, ASA, or AAS) would demonstrate their congruence, but without specific measurements, we can't identify which theorem applies.

The subject area of this question is Geometry, more specifically, the concepts concerning triangles. The given notation, DEF - XZY, suggests that the student wants to establish the congruency between the two triangles DEF and XZY.

Based on the information provided, the student is likely referring to a Congruence Theorem, which is one of the primary methods to determine if two given triangles are congruent. The main Congruence Theorems are: SSS (Side-Side-Side), SAS (Side-Angle-Side), ASA (Angle-Side-Angle), and AAS (Angle-Angle-Side).

Without any additional specification, it's impossible to definitively say which theorem supports DEF - XZY. The student would need to provide specific measurements related to the triangles DEF and XZY, such as the lengths of the sides or the measures of the angles, to determine which Congruence Theorem applies.

We have been given am image of point B on coordinate plane. We are asked to plot the mage of point B under a dilation about point P  with a scale factor of [tex]\frac{1}{2}[/tex].

To solve our given problem, we need to find vertical distance and horizontal distance between point B and point P.  

We can see that vertical distance is 4 units as shown in the attachment and horizontal distance is 6 units.

Since the scale of dilation is [tex]\frac{1}{2}[/tex], so the vertical distance between point P and B' would be [tex]\frac{1}{2}[/tex] of 4 that is [tex]\frac{1}{2}(4)=2[/tex].

The horizontal distance between point P and B' would be [tex]\frac{1}{2}[/tex] of 6 that is [tex]\frac{1}{2}(6)=3[/tex].

Now we will count 3 units to left of point P and 2 units upwards. That will be the position of point B'.

The below-attached graph represents the image of point B under a dilation about point P with a scale factor of 1/2.

To plot the image of point B under a dilation about point P with a scale factor of 1/2, follow these steps:

The point where this line intersects the vertical line through point C will be the image of point B under the dilation with a scale factor of 1/2.

Thus, the image of point B will be half as far away from point P as point B.

Hence, the below-attached graph represents the image of point B under a dilation about point P with a scale factor of 1/2.

1/y = b

So, now the equation:

2a +3b  = 13   --------------------(i)

5a - 4b  = -2  --------------------(ii)

To eliminate a, Multiply equation (i) by 5 and multiply (ii) by (-2)

(i)*5             10a  + 15b = 65

(ii)*(-2)        - 10a + 8b  = 4      ( Now add, a will be eliminated}

                            23b = 69

b= 69/23

b = 3

Plug in the value of b in equation (i)

2a + 3*3 = 13

2a + 9 = 13

2a  = 13 - 9

2a = 4

a= 4/2

a = 2  

Now a = 1/x   ------>x = 1/a = 1/2

b = 1/y ----------->y = 1/b = 1/3

Relation C: {(3,4), (3,5)} does not represent a function because it has the same first component with different outputs.

In Mathematics, a relation is defined as a set of ordered pairs. A relation is considered as a function if for each input (x value), there is exactly one output (y value). In other words, no two distinct ordered pairs in the function have the same first component. Looking at the options given:

The relation C. {(3,4), (3,5)} does not represent a function because there are two distinct ordered pairs with the same first component (or x-value) which is 3, but with two different y-values which are 4 and 5. Therefore, this relation violates the definition of a function.

https://brainly.com/question/35114770

#SPJ2

Final answer:

The relation that does not represent a function is Option C: {(3, 4), (3, 5)} because the number 3 in the domain is paired with two different values in the range, contradicting the definition of a function.

Explanation:

The relation that does not represent a function is Option C: {(3, 4), (3, 5)}. This is because a function is defined as a set of ordered pairs where each element of the domain (the first value in each pair) must correspond to exactly one element in the range (the second value in each pair). Option C depicts the number 3 in the domain being paired with both 4 and 5 in the range, which violates this rule. Therefore, Option C does not satisfy the definition of a function.

Option A, B, D, and E each show that every element of the domain is matched with only one unique value in the range, indicating they are all functions.

Answer:

mean = mode

Step-by-step explanation:

To make this easier, let's find the mean, median, and mode.

Mean: Sum of a set of numbers divided by number of terms

Median: Middle number of data when data is in numerical order

Mode: Number that occurs most often in data

To find the mean, add all the values together. -1 - 1 + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3 = 11. Now, divide by the number of terms, which is 11. 11/11 = 1. The mean is 1.

To find the median, look at the number in the middle of the data. -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3. The median is 1.

To find the mode, look at the number that occurs most often. There are 4 1's, so the mode is 1.

Since all numbers are equal, the only possible answer is the first option.

The mean, median, and mode are all equal; thus, a.) mean = mode is true.

Sum of all values: (-1) + (-1) + 0 + 1 + 1 + 1 + 1 + 2 + 2 + 2 + 3 = 11

Number of values: 11

Mean = Total sum / Number of values = 11 / 11 = 1

Arrange the values in ascending order: -1, -1, 0, 1, 1, 1, 1, 2, 2, 2, 3

The middle value (6th value) is 1

Median = 1

The value that appears most frequently is 1 (occurs 4 times)

Mode = 1

Comparing these values:

Mean = 1

Median = 1

Mode = 1
