515 to 103 markup percentage rate
The mark up percentage gained by the shopkeeper is 400%.
What is termed as the markup percentage rate?The markup percentage is the difference between how an item costs this same seller and what the customer pays. The greater the markup, as a percentage of a cost, the greater the profit.The markup percentage of a product is the ratio of its gross profit to its cost.It is most useful for companies that sell physical goods in industries in which prices are linked to the cost of acquiring more.The percentage of markup varies by industry as well as product. Other than discovering a price that did work for both your company and your customers, there is no golden rule.For the given question.
The cost of the item is $103.
The customer pays is $515.
The mark up percentage is -
mark up percentage = 515 - 103 / 103
mark up percentage = 4 × 100%
mark up percentage = 400 %.
Thus, the mark up percentage gained by the shopkeeper is 400%.

How do I get the other number and it’s bye using writing perfect-square trinomials
25
1) We must start by reminding the binomials. Since this question refers to a perfect square trinomial then we can write:
[tex](a-b)^2=a^2-2ab+b^2[/tex]2) Now we can look at the expression. Let's start by dividing that 10 by 2, since we have to write that -10x as 2 times the product of x and the other term:
[tex]\begin{gathered} -\frac{10}{2}=5 \\ (x-5)^2=x^2-2(5)(x)+5^2=x^2-10x+25 \end{gathered}[/tex]Note that the second term is 5²= 25

The Nya will pay $46.42 for the sweater. The decimal equivalent of a 20 percent discount is 0.20. To calculate the savings in dollars, multiply the decimal discount by the item's price. For instance, if the item's original price is $24, you would multiply 0.2 by that amount to get $4.80.
Calculation of amount paid to sweater?We have been given that Nya wants to buy a sweater that had an original price of $55. The sweater is now discounted 20%.
the price of sweater after20% discount is 55-20% of 55
The price of the sweater after discount =55-(20/100*55)
The price of the sweater after discount=55-(0.20*55)
The price of the sweater after discount=55-11
The price of the sweater after discount=44
SO The price of the sweater after discount is $44
Now let us find the price of sweater after adding 5.5% sales tax
The price of sweater after sales tax =44+(5.5/100*44)
The price of sweater after sales tax=44+(0.055*44)
The price of sweater after sales tax=44+2.42
The price of sweater after sales tax=46.42
$46.42 is paid for sweater after sales tax
Hence, The Nya will pay $46.42 for the sweater.

Forty years ago, uncle Luke was 5 times
as old as his
nephew. Today, Uncle Luke is 16 yeas older than his nephew. How
old is uncle Luke now?
Answer: Uncle Luke is at 50 years old
Step-by-step explanation: I went through trial and error first with simple t-charts. In the first one, I simply implemented the piece of info that Luke was 5 times older than the nephew. But then, I realized that Luke would always be 5 years older than his nephew. Here was the info for that t-chart:
[tex]\left \{ {{N=1} \atop {L=5}} \right. \left \{ {{N=2} \atop {L=6}} \right. \left \{ {{N=3} \atop {L=7}} \right.[/tex]
Next, I tried a chart starting with the nephew at 2 years of age, and got an age gap of 8. This helped me realize that I would have to start at 4 years of age in order to have an age gap of 16
[tex]\left \{ {{N=2} \atop {L=10}} \right.[/tex] | [tex]\left \{ {{N=4} \atop {L=20}} \right. \left \{ {{N=5} \atop {L=21}} \right.[/tex] (remember there are 1 increments)
Next, I realized that N=4, L=20 was 40 years ago, so if now the nephew was 44, we can increment 16 to get 50
44+16=50

What is the midpoint of line segment (-6,-10) ,(-2,-8)
The mid-point of two coordinates is the average of the x and y coordinates thus the midpoint of the line segment with endpoints (-6,-10),(-2,-8) is (-4,-9).
What is a line segment?A line section that can connect two places is referred to as a segment.
A line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
The midpoint associated with two points (x₁, y₁) and (x₂, y₂) is given by
x = (x₁ + x₂)/2 , y = (y₁ + y₂)/2
x = (-6 - 2)/2 = -4 , y = (-10 - 8)/2 = -9
So, the coordinate will be (-4,-9).
Hence "The mid-point of two coordinates is the average of the x and y coordinates thus the midpoint of the line segment with endpoints (-6,-10),(-2,-8) is (-4,-9)".

Ereed wash c cars to have enough to purchase the bicycle.
Select the 3 orrect equations below that can be used to represent when she will be able to purchase the bicycle she wants
The correct equations which can be used to represent when she will be able to purchase the bicycle she wants are:
250 = 125+25c125 = 25cc = 5Given, Eva wants to buy a bicycle.
The cost of bicycle is = $250
Saving's of Eva = $125
Eva plans on washing cars for $25 per car.
Eva wash 'c' cars to have enough to purchase the bicycle.
cost of bicycle = saving's of Eva + Eva washing 'c' cars for $25 per car.
⇒ 250 = 125 + 25c
arrange the like terms on one side.
⇒ 250 - 125 = 25c
⇒ 125 = 25c
⇒ 25c = 125
⇒ c = 125/25
⇒ c = 5
hence Eva washes 5 cars to earn $125 which gets added to the savings and becomes the cost of the bicycle she wants to purchase.
⇒ cost of bicycle = 125+25(5)
⇒ cost of bicycle = 125+125
⇒ cost of bicycle = $250
Hence we got the required answers.

A) distribution of x and its parameter(s) is (λ^x e^-λ ) / x!
B) standard deviation of x is 1
C) probability that x is (inclusively) within one standard deviation of the mean of x is 0.7358
The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.
The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.
A) The poisson distribution with mean is followed by X = λ = 1
Therefore, ≈ (λ = 1)
Distribution of X is:
(λ^x e^-λ ) / x! , x = 0, 1, 2, 3 ......

Answer: A z=9
Step-by-step explanation:
Answer:
z = 12
Step-by-step explanation:
To understand the equation, you must first know that m∠a = 108°. It equals that because a regular five-sided polygon has an interior angle of 108° each.
Next, you would want to group all constants to the right side of the equation. By doing so, you want to subtract 72 from both sides.
(3z + 72) - 72 = 108 - 72
3z = 36
Lastly, you want to isolate the z by dividing 36 by 3.
z = 36 ÷ 3
z = 12

Find the measure of each angle in the diagram
The measure of each angle in the diagram is as follows:
3y + 11 = 50 degrees10y = 130 degrees(4x - 22) = 50 degrees7x + 4 = 130 degreesHow to find the angles in intersecting lines?When lines intersect, angle relationships are formed such as vertically opposite angles, adjacent angles etc.
Therefore, the measure of each angle in the diagram can be calculated as follows:
10y = 7x + 4 (vertically opposite angles)
3y + 11 = 4x -22(vertically opposite angles)
Therefore,
10y - 7x = 4
3y - 4x = -22 - 11
10y - 7x = 4
3y - 4x = -33
multiply equation(ii) by 1.75
10y - 7x = 4
5.25y - 7x = - 57.75
subtract equation(ii) from equation(i)
Hence,
4.75y = 61.75
y = 61.75 / 4.75
y = 13
Therefore,
10(13) - 7x = 4
130 - 7x = 4
130 - 4 = 7x
7x = 126
x = 126 / 7
x = 18
Therefore, the unknown angles are as follows;
3y + 11 = 3(13) + 11 = 50 degrees10y = 10(13) = 130 degrees(4x - 22) = 4(18) - 22 = 50 degrees7x + 4 = 7(18) + 4 = 130 degreeslearn more on angles here: https://brainly.com/question/18193074
