A New Suit Matthew is shopping for a new suit. At K&G Menswear, he finds that the sale price of a suit that was reduced by 25% is $187.5 . Determine the regular price of the suit.
The regular price of the suit is $250.
What is the discounts ?
A discount is a reduction in the price of a product or service. It is often used as an incentive to encourage customers to buy a product or service, especially when the original price is considered too high.
Let's assume the regular price of the suit to be x.
According to the problem, the sale price of the suit after a 25% discount is $187.5.
This can be written as:
x - 0.25x = 187.5
Simplifying the equation:
0.75x = 187.5
Dividing both sides by 0.75:
x = 250
Hence, the regular price of the suit is $250.

The function h(x) is a continuous quadratic function with a domain of all real numbers. The table lists some of the points on the function. x h(x) −6 12 −5 7 −4 4 −3 3 −2 4 −1 7 What are the vertex and range of h(x)?
The vertex of the parabola is at the point (-3/2, -21/4) and the range of the function would be (-21/4, infinity).
What is the quadratic function?
A quadratic function is a function of the form [tex]f(x) = ax^2 + bx + c,[/tex] where a, b, and c are constants, and a is not equal to 0. It is a type of polynomial function that can be graphed as a parabola, which is a symmetric curve that opens either upwards or downwards.
Given the table of points for the continuous quadratic function h(x), we can find the vertex and range of the function. Since the function is quadratic and continuous, it can be represented in the standard form [tex]f(x) = a(x - h)^2 + k[/tex], where (h, k) is the vertex of the parabola.
To find the vertex, we can use the fact that the x-coordinate of the vertex is given by -b/2a, where a and b are the coefficients of the quadratic term and the linear term, respectively. In this case, a = 1 (since the function is continuous and quadratic), and b can be found using any two points on the parabola:
[tex]b = (h(x2) - h(x1))/(x2 - x1) = (4 - 7)/(-2 + 1) = 3[/tex]
Therefore, the x-coordinate of the vertex is x = -b/2a = -3/2. To find the y-coordinate of the vertex, we can evaluate the function at this value of x:
[tex]h(-3/2) = (1)(-3/2 - h)^2 + k[/tex]
To solve for k, we can use one of the points on the parabola, say (-6, 12):
[tex]12 = (1)(-6 - h)^2 + k[/tex]
Expanding and simplifying, we get:
[tex]12 = (h - 6)^2 + k[/tex]
Substituting -3/2 for h, we get:
[tex]12 = (-(3/2) - 6)^2 + k\\\\12 = 81/4 + k\\\\k = -21/4[/tex]
Therefore, the vertex of the parabola is at the point (-3/2, -21/4).
To find the range of the function, we can look at the shape of the parabola. Since the coefficient of the quadratic term is positive, the parabola opens upwards, and the vertex is the lowest point on the graph. Therefore, the range of the function is all real numbers greater than or equal to the y-coordinate of the vertex, which is -21/4. In interval notation, we can write the range as (-21/4, infinity).
Hence, the vertex of the parabola is at the point (-3/2, -21/4) and the range of the function would be (-21/4, infinity).

Pls help Perimeter and Area
Answer:
Step-by-step explanation:
Since the circle is inscribed in the square, the diameter of the circle is equal to the side length of the square. Therefore, the diagonal of the square is twice the radius of the circle, or 10 mm.
To find the area of the square, we can use the formula A = s^2, where s is the side length of the square. The diagonal of the square is √2 times the side length, so we have:
10 mm = √2 x s
s = 10 mm / √2
The area of the square is:
A = s^2 = (10 mm / √2)^2 = 100 mm^2 / 2 = 50 mm^2
To find the area of the circle, we can use the formula A = πr^2, where r is the radius of the circle. We are given that the radius is 5 mm, so:
A = π(5 mm)^2 = 25π mm^2
To find the shaded section, we need to subtract the area of the circle from the area of the square. The shaded section is the remaining area of the square after the circle has been inscribed. Therefore, the shaded section is:
Shaded Section = Square Area - Circle Area
Shaded Section = 50 mm^2 - 25π mm^2
Shaded Section ≈ 10.79 mm^2 (rounded to two decimal places)
Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options. x2 + (y – 3)2 = 36 x2 + (y – 5)2 = 6 (x – 4)² + y² = 36 (x + 6)² + y² = 144 x2 + (y + 8)2 = 36
Answer: x^2 + (y – 3)^2 = 36
Step-by-step explanation:
The standard equation of a circle with center at (h, k) and radius r is
(x - h)^2 + (y - k)^2 = r^2.
If the center lies on the y-axis, then h = 0: (x - 0)^2 + (y - k)^2 = r^2
If the circle diameter is 12, then the circle radius is 6, and so r^2 = 36
So, among the given equations, your
x^2 + (y – 3)^2 = 36 is correct

Therefore , the solution of the given problem of equation comes out to be (1, -4) is a solution to the equation 4x - 2y = 12.
How do equations work?The equivalent sign (=) is used in arithmetic equations to signify the equality of two propositions. It is shown that it is possible to compare various numerical factors by using mathematical techniques, which have served as manifestations of reality. For instance, the equal sign divides the number 12 even the solution y + 6 = 12 in two distinct portions. How many characters also are present from either end of such a character can be calculated. Conflicting symbol readings are prevalent.
Here,
To find the values of missing entries, we can pick any arbitrary value of x and solve for y. Let's take x=1.
4(1) - 2y = 12
Simplifying the equation, we get:
-2y = 8
Dividing both sides by -2, we get:
y = -4
So, when x=1, y=-4. Therefore, the missing entries in the table are (1, -4).
Using this value, we can also check that the equation 4x - 2y = 12 is satisfied:
4(1) - 2(-4) = 4 + 8 = 12
So, (1, -4) is a solution to the equation 4x - 2y = 12.

The solution to the inequality is x ≤ 1.
What is inequality?Inequality in mathematics is when two values are not equal. It can be expressed using symbols such as >, <, ≥ and ≤. This can be used to compare two values, express a range of values, or indicate that one value is greater or less than another. Inequality is a powerful tool for solving mathematical problems, as it can be used to deduce relationships between different variables.
To solve this inequality, we must first perform the operations on the left side of the equation to get an expression equal to 4. We can start by simplifying the fraction on the left side of the equation. We can multiply both the numerator and denominator by x, which will give us 5x - 3 = x + 2x. We can then add 3 to both sides to get 5x = 3 + 2x, which can then be simplified to 3x = 3. Finally, we can divide both sides by 3 to get x = 1. Therefore, the solution to the inequality is x ≤ 1.

Find the perimeter of the triangle whose vertices are (2,−2)
, (−2,0)
, and (−1,−7)
. Write the exact answer. Do not round.
The exact perimeter of the triangle is 2√5 + √34 + 5√2.
According to given information :To find the perimeter of the triangle, we need to find the distances between its vertices and add them up. Let's use the distance formula to find the three distances:
Distance between (2, -2) and (-2, 0):
d1 = √[(2 - (-2))^2 + (-2 - 0)^2]
= √[(4)^2 + (-2)^2]
= √(16 + 4)
= √20
= 2√5
Distance between (2, -2) and (-1, -7):
d2 = √[(2 - (-1))^2 + (-2 - (-7))^2]
= √[(3)^2 + (5)^2]
= √(9 + 25)
= √34
Distance between (-2, 0) and (-1, -7):
d3 = √[(-2 - (-1))^2 + (0 - (-7))^2]
= √[(-1)^2 + (7)^2]
= √(1 + 49)
= √50
= 5√2
Now, we can add up the distances to find the perimeter:
perimeter = d1 + d2 + d3
= 2√5 + √34 + 5√2
Therefore, the exact perimeter of the triangle is 2√5 + √34 + 5√2.
What is perimeter of triangle ?The perimeter of a triangle is the total length of its three sides. To find the perimeter, you simply add the lengths of the three sides together.

What is insertion sort?
Insertion sort is a simple sorting algorithm that works by repeatedly iterating through the elements of an array, or a list, and inserting each element into its proper position within the sorted portion of the array. The algorithm maintains a sorted sublist of elements, which starts as the first element of the array, and then iterates through the remaining unsorted elements one-by-one, comparing each element with the elements in the sorted sublist and moving them to the right until the correct position is found. In other words, insertion sort iteratively expands the sorted sublist by inserting each new element into its correct position, until the entire array is sorted. The time complexity of the insertion sort algorithm is O(n^2) in the worst-case scenario, where n is the number of elements in the array, but it can perform much better on small datasets or partially sorted arrays.
According to given conditions:
For the first question:
After the first pass of the outer loop, the array will be [2, 5, 4, 1, 3, 6]. After the second pass, the array will be [2, 4, 5, 1, 3, 6]. After the third pass, the array will be [1, 2, 4, 5, 3, 6]. Therefore, the answer is (C) [1, 2, 4, 5, 3, 6].
For the second question:
Statement 1 will execute 6 times because there are 6 elements in the array. Statement 2 will also execute 6 times because each element in the array will be moved to its correct position during the insertion sort. Therefore, the answer is (E) 6, 6.
For the third question:
To correctly separate the words in listofWords with commas and enclose them in braces, we need to iterate through the list and add each word to the result string followed by a comma (except for the last word) and a space. Then we need to remove the last comma and space and add the opening and closing braces. This can be achieved with the following expression and condition:
Expression: listofWords.get(k) + ", "
Condition: k != listofWords.size() - 1
Therefore, the answer is (A) expression: listofWords.get(k) + ", ", condition: k != listofWords.size() - 1.
For the fourth question:
To sort the integers in elements in descending order, we need to make two changes to the sort method:
I. Replace line 9 with: if (elements[k] > elements[index])
II. Replace lines 15-17 with:
Line 15: int temp = elements[index];
Line 16: elements[index] = elements[j];
Line 17: elements[j] = temp;
III. Replace line 3 with: for (int j = elements.length - 1; j > 0; j--) and replace line 7 with: for (int k = 0; k < j; k++)
Therefore, for the given insertion sort program the answer is (E) I, II, and III.

Find the value of x from the adjoining figure
The value of x from the adjoining figure given as pentagon is 85°.
What is angle?An angle is a geometric figure formed by two rays, or lines, that share a common endpoint, called the vertex. The measure of an angle is typically expressed in degrees, radians, or other units of angular measurement, and it represents the amount of rotation between the two rays. Angles are often used in geometry, trigonometry, physics, and other fields to describe the orientation of objects and the relationships between them. Some common types of angles include acute angles (less than 90°), obtuse angles (greater than 90°), and right angles (exactly 90°).
Here,
This is a pentagon with sum of angle as 540 degrees.

Which of the following claims is best supported by the table?
The most likely number of employees who work on a given day is 24.
A. The mean number of employees who work on a given day is equal to the median number of employees who work on a given day.
B. The mean number of employees who work on a given day is greater than the median number of employees who work on a given day.
C. The mean number of employees who work on a given day is less than the median number of employees who work on a given day.
D. On a given day, the number of employees who work at the restaurant occurs with equal probabilities.
Number of Employees Probability
20 0.1
21 0.1
22 0.1
23 0.4
24 0.3
The mean number of employees who work on a given day is less than the median number of employees who work on a given day and option C is correct.
What is mean median and mode?In statistics, we frequently choose a representative value that roughly describes the full collection to represent a set of data. The label "measure of central tendency" denotes that this representative value is one around which the data is centred. The mean, median, and mode are these central tendencies.
Mean = sum of all values/frequency
Mean = (20(0.01) + (21(0.1)) + (22(0.1)) + (23(0.4)) + (24(0.3))
mean is 22.7.
The median id the value of X for which P(X<x) is greater than or equal to 0.5 and P(X>x) is greater than or equal to 0.5. Therefore, median is 23.
Mode is the value of X having maximum probability. Therefore, mode is 23.
Hence, the mean number of employees who work on a given day is less than the median number of employees who work on a given day and option C is correct.

The solution of the given problem of area comes out to be the regular decagon is approximately 324.16 cm².
Describe Surface Area.Its surface area is a reliable indicator of its overall size. When figuring out the right triangle squared, the environment is taken into account. The surface area of everything determines its overall size. The total of the volumes from each of the twelve vertical sides makes up the water volume inside a cuboid. Utilize the following formula to get the box's dimensions: The region is represented by 2lh, 2lw, & 2hW. (SA). The area is represented by the flexible shape's entire surface area.
Here,
The area of a regular decagon can be calculated using the formula:
Area = (perimeter x apothem) / 2
For a regular decagon with a side of 6.8 cm and an apothem of 9.52 cm, the perimeter can be calculated as 10 times the length of the side, that is:
Perimeter = 10 x 6.8 cm = 68 cm
Therefore, the area of the decagon is:
Area = (68 cm x 9.52 cm) / 2 = 324.16 cm²
So, the area of the regular decagon is approximately 324.16 cm².
