The shoes are on sale for 39.99. If they were marked down 20%, what was the original price?
Final answer:
The original price comes out to $49.99 when rounded to the nearest cent.
Explanation:
To determine the original price of an item that has been marked down by 20%, we need to understand that the current price represents 80% of the original price (100% - 20% = 80%).
Therefore, the sale price is 80% of the original price. If the shoes were on sale for $39.99, we can set up an equation where the original price is represented by x, and the sale price is 80% of x, or 0.80x.
The equation would be 0.80x = $39.99.
To find the original price, we divide both sides by 0.80:
x = $39.99 / 0.80
x = $49.9875
Therefore, the original price of the shoes was $49.99 when rounded to the nearest cent.

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
The cost of 1 knife is £5.52
Emery bought 3 cans of beans that had a total weight of 2.4 pounds. If each can of beans weighed the same amount, which model correctly illustrates the relationship? Check all that apply
Answer:
Figure 2 and 3
Step-by-step explanation:
This question is incomplete, please find the figures in the attachment.
Number of cans of beans bought by Emery = 3
Total weight of cans = 2.4 pounds
weight of each can = [tex]\frac{2.4}{3}[/tex] = 0.8 pounds
If x be the number of cans and y represents the total weight then the model for this situation will be
y = 0.8x
Figure 1 :
From this graph weight of each can = [tex]\frac{20}{16}=1.25[/tex] pounds
so this graph is not the correct choice.
Figure 2:
From this graph weight of each can = [tex]\frac{8}{10}[/tex] = 0.8 pounds
So this graph is the correct choice.
Figure 3 :
From the given table, weight of each can = [tex]\frac{4}{5}=0.8[/tex] pounds
So the table shows the relationship.
Figure 4 :
From the given table, weight of each can = [tex]\frac{5}{4}[/tex] = 1.25 pounds
so this table is not the correct choice.
Therefore, figure 2 and 3 is illustrate the relationship.

Find the area of the shaded regions:
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.

Which of the following theorems verifies that DEF - XZY?
Answer:
AA
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.
Explanation: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.

In Ben's state, the weekly unemployment compensation is 55% of the 26-week average for
the two highest-salaried quarters. A quarter is three consecutive months. For July, August,
and September, Ben earned a total of $22,400. In October, November, and December, he
earned a total of $22,800. Determine Ben's weekly unemployment compensation.
Ben's weekly unemployment compensation is $956.15
What is percentage?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

To determine Ben's weekly unemployment compensation, we need to calculate the average of his two highest-salaried quarters and then multiply it by 55%.
Therefore, Ben's weekly unemployment compensation is $4,106.67.
Explanation:To determine Ben's weekly unemployment compensation, we need to calculate the average of his two highest-salaried quarters and then multiply it by 55%. First, let's calculate the average for each quarter:
Next, let's determine the two highest averages:
The highest average: $7,600The second highest average: $7,466.67Now, we can calculate the weekly unemployment compensation:
The highest average * 55% = $7,600 * 0.55 = $4,180
The second highest average * 55% = $7,466.67 * 0.55 = $4,106.67
Therefore, Ben's weekly unemployment compensation is $4,106.67.

15.425 cm is it without terms of pie
Step-by-step explanation:
you need to put it into terms of pie
Answer:
3pi + 6 units.
Step-by-step explanation:
The perimeter = the diameter + curved part.
Radius = 3 so the diameter = 2*3 = 6.
Length of the curved part = 1/2 * circumference of the circle = 1/2 * pi * diameter.
Perimeter = 6 + 1/2 pi * 6
= 3pi + 6 units.
Plot the image of point B under a dilation about point P
with a scale factor of
Please find the attached file.
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:
Draw point P on the coordinate plane at any location.From point P, move vertically 6 units up and label the new point as B.From point P, move horizontally 4 units to the left and label the new point as B'.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.

Which relation does not represent a function?
A. {(3, 0), (0, 3)}
B. {(6, -2), (5, -2)}
C. {(3, 4), (3, 5)}
D. {(5, 5), (-5, -5)}
E. {(1, -2), (-2, 1)}
Relation C: {(3,4), (3,5)} does not represent a function because it has the same first component with different outputs.
Explanation: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:
A. {(3, 0), (0, 3)}B. {(6, -2), (5, -2)}C. {(3, 4), (3, 5)}D. {(5, 5), (-5, -5)}E. {(1, -2), (-2, 1)}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.

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.
Find the distance between the two points (4, 1) and (10,9)
The distance between the two points (4, 1) and (10,9) is 10 units
CoordinatesAssume the points are A and B
The coordinates of the points are given as:
Point A = (4,1)Point B = (10,9)DistanceThe distance (d) between two points A and B is calculated as:
[tex]d = \sqrt{(x_1 -x_2)^2 + (y_1 -y_2)^2}[/tex]
So, the above equation becomes
[tex]d = \sqrt{(4-10)^2 + (1 -9)^2}[/tex]
[tex]d = \sqrt{100}[/tex]
Take the positive square root of 100
[tex]d = 10[/tex]

Answer:
c
Step-by-step explanation:
Let 1/x = a &
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
[tex]x+y=\frac{1}{2}+\frac{1}{3}\\\\=\frac{1*3}{2*3}+\frac{1*2}{3*2}\\\\=\frac{3}{6}+\frac{2}{6}\\\\=\frac{5}{6}[/tex]
