A store sells chips that are usually $6.00. They are on sale for $5.28. What percentage are they marked down?
Answer:
the chips are marked down by 12%.
Step-by-step explanation:
To calculate the percentage discount, you can use the formula:
percentage discount = (original price - sale price) / original price x 100%
Plugging in the values given in the problem, we get:
percentage discount = (6.00 - 5.28) / 6.00 x 100%
percentage discount = 0.72 / 6.00 x 100%
percentage discount = 0.12 x 100%
percentage discount = 12%
Answer:
The answer is 12%
Step-by-step explanation:
6 - 5.28 = 0.72
0.72/6 = 0.12
0.12 is a decimal, but written as a percent is 12%.

B) the graph is attached accordingly.
C) In the context of the given problem, to store 43 liters of coffee, she needs at least 8 dispensers, as given by the function D(L).
What is the explanation for the above response?a) To complete the table, we need to use the given function D(L) to determine the number of beverage dispensers needed to hold different amounts of coffee.
We know that each beverage dispenser can hold 6 liters of coffee, so we can start by dividing the amount of coffee needed by 6 and rounding up to the nearest integer to get the number of dispensers needed.
D(L) = ceil(L/6)
Using this formula, we can complete the table as follows:
L D(L)
0 0
3 1
4 1
6.5 2
10 2
11.9 2
15 3
Note that for L=0, we don't need any dispensers, so the value of D(L) is 0. For all other values of L, we divide by 6 and round up to get the corresponding value of D(L).
b) The graph is attached.
c) In the context of the given problem, the function D(L) gives the minimum number of beverage dispensers needed to hold L liters of coffee, assuming each dispenser can hold 6 liters.
So, D(43) = 8 means that if Giada needs to brew and store 43 liters of coffee, she will need at least 8 beverage dispensers. Each dispenser can hold 6 liters, so the first 7 dispensers will be completely filled, and the last dispenser will be partially filled with the remaining coffee.
In other words, if Giada fills 7 dispensers completely, she will have used 42 liters of coffee, and the remaining 1 liter of coffee will be stored in the 8th dispenser. Therefore, to store 43 liters of coffee, she needs at least 8 dispensers, as given by the function D(L).

Compute the probability that a randomly selected person does not have a birthday on the 1st day of the month.
Answer:
0.9973 or 364/365
Step-by-step explanation:
Assuming that every day of the year is equally likely to be someone's birthday, the probability that a randomly selected person has a birthday on the 1st day of the month is 1/365, since there are 365 possible birthdays in a year.
Therefore, the probability that a randomly selected person does not have a birthday on the 1st day of the month is:
P(not on 1st day) = 1 - P(on 1st day)
P(not on 1st day) = 1 - 1/365
P(not on 1st day) = 364/365
So, the probability that a randomly selected person does not have a birthday on the 1st day of the month is 364/365 or approximately 0.9973.
In a recent survey, 60% of the community favored building a supermarket in their neighborhood. If 25 citizens are chosen, what is the variance of the number favoring the supermarket?
The variance of the number of citizens favoring the supermarket is 6.
To find the variance of the number of citizens favoring the supermarket, we need to use the binomial distribution formula:
Variance = n × p × (1 - p)
where n is the number of trials (25 in this case), p is the probability of success (0.6 in this case), and (1 - p) is the probability of failure.
Plugging in the values, we get:
Variance = 25 × 0.6 × (1 - 0.6)
Variance = 25 × 0.6 × 0.4
Variance = 6
The binomial distribution is a probability distribution that models the number of successes in a fixed number of independent trials, where each trial has only two possible outcomes, success or failure. In this case, the trials are the 25 citizens who were chosen, and the success is the event of favoring the supermarket, which has a probability of 0.6.

Given ABC shown in the graph below, XYZ is found according to the following combined transformation function.
Look at both photos below to help answer the question.
The coordinates of triangle XYZ are X(-2,-2), Y(2,4), and Z(-4,8).
Describe Transformation?In mathematics, a transformation refers to a change or modification of an object's position, shape, size, or orientation in a coordinate plane or space. Transformations can be described as functions that map the points or vertices of an object to new positions in the plane or space.
Common transformations include:
Translation: a transformation that moves an object without changing its size, shape, or orientation. Translation involves shifting all points of the object by the same distance in the same direction.
Rotation: a transformation that turns an object about a fixed point or axis by a certain angle. Rotation preserves the size and shape of the object, but changes its orientation.
Scaling: a transformation that changes the size of an object by multiplying the coordinates of each point by a fixed factor. Scaling can either enlarge or reduce an object.
Since the transformation function is not provided, I'll assume that D2(ABC) means dilating the triangle ABC with center at the origin and a scale factor of 2.
To find the coordinates of the new triangle XYZ, we can apply the dilation transformation to each vertex of the original triangle:
For vertex A(-1,-1), we multiply its coordinates by the scale factor 2, giving us point X(-2,-2).
For vertex B(1,2), we multiply its coordinates by the scale factor 2, giving us point Y(2,4).
For vertex C(-2,4), we multiply its coordinates by the scale factor 2, giving us point Z(-4,8).
Therefore, the coordinates of triangle XYZ are X(-2,-2), Y(2,4), and Z(-4,8), as shown below:

What is area?In mathematics, area is a measurement of the size of a two-dimensional surface or shape, usually measured in square units such as square meters, square centimeters, or square feet. It is the amount of space inside the boundary of a flat object or shape.
Here,
To calculate the area of the base of the new container, we need to find the radius of the container first. Since the diameter is given as 10 cm, the radius would be half of that, which is 5 cm. The formula for the area of a circle is A = πr², where A is the area and r is the radius. So, substituting the values, we get:
A = π(5 cm)²
A = π(25 cm²)
A = 25π cm²
However, the answer choices are not in this format. To simplify the answer, we can use the value of π as approximately 3.14 (rounded to two decimal places). So, the area of the base would be:
A = 25π cm²
A ≈ 25(3.14) cm²
A ≈ 78.5 cm²

81 + 73= 154
180 - 154= 26
Answer:
∠m = 26
Step-by-step explanation:
We know that the sum of the interior angles in a triangle is added up to 180°.
Accordingly,

Yes, quadrilaterals LMNO and PQRS are similar because a rotation and a dilation map quadrilateral LMNO onto PQRS.
Yes, quadrilaterals LMNO and PQRS are similar because a reflection and a dilation map quadrilateral LMNO onto PQRS.
No, quadrilaterals LMNO and PQRS are not similar because their corresponding segments are not proportional.
The correct answer is (d) No, quadrilaterals LMNO and PQRS are not similar because their corresponding sides are not proportional.
What are quadrilaterals?A quadrilateral is a geometric shape with four sides and four corners.
To be classified as a quadrilateral, its shape must be a closed figure with four straight sides and four interior angles.
To determine quadrilaterals are similar, we need to check if corresponding angles are congruent and corresponding sides are proportional.
Checking corresponding angles are congruent:
∠ L to ∠P.
∠M to ∠Q.
∠ N to ∠ R.
∠O to ∠S.
All corresponding angles are congruent. Therefore, quadrilaterals have the same shape.
Check if corresponding sides are proportional.
LM =√((-1 - (-2))² + (4 - 2)²) = √(2² + 2²) = 2√2
MN = √((3 - (-1))² + (4 - 4)²) = √(4²) = 4
NO = √((4 - 3)² + (2 - 4)²) = √(2² + 2²) = 2√(2)
OL = √((-2 - 4)² + (2 - (-6))²) = √(6² + 8²) = 10
PQ = √((4 - 2)² + (-2 - (-6))²) = √(2² + 4²) = 2√5
QR = √((12 - 4)² + (-2 - (-2))²) = √(8²) = 8
RS = √((15 - 12)² + (-6 - (-2))²) = √(3² + 4²) = 5
SP = √((2 - 15)² + (-6 - (-6))²) = √(13²) = 13
LM / PQ = (2√2) / (2√5) = √(8/5)
MN / QR = 4 / 8 = 1/2
NO / RS = (2√(2)) / 5√(1) = (2/5)√(2)
OL / SP = 10 / 13
The corresponding sides are not proportional because they are not all equal or proportional to each other. Therefore, we can conclude that the quadrilaterals LMNO and PQRS are not similar.

Jacque bought 2.5 pounds of dark chocolate covered pecans at $0.30 per ounce. In dollars and cents, what was the cost of these pecans?
Answer:
$12.00
Step-by-step explanation:
We know that 1 pound = 16 oz. Thus, we can create a proportion to find how many ounces (x) is 2.5 pounds:
[tex]\frac{1}{16}=\frac{2.5}{x}\\ x=(2.5*16)\\ x=40[/tex]
Since 2.5 pounds = 40 oz, we can now multiply 40 by 0.30 to find the price of 40 ounces of peacans priced at $0.30/ounce:
40 * 0.30 = $12.00

Sam's height is 15 centimeters less than 2 times Martha's height. If Sam is 185 centimeters tall, and Martha's height is x, the relationship between the heights can be represented by the equation 2x − 15 = 185. What is Martha's height?
Step-by-step explanation:
The equation 2x − 15 = 185 represents the relationship between Sam's and Martha's heights. We can solve for x, which represents Martha's height, by isolating x on one side of the equation:
2x − 15 = 185
Add 15 to both sides of the equation:
2x = 200
Divide both sides of the equation by 2:
x = 100

A 90 degree clockwise rotation about the point (0,0), the new coordinates of Point B are (3, -1) and the new coordinates of Point C are (1, -2).
How do you check if a quadrilateral is a rectangle on a graph?A quadrilateral can be proven to be a rectangle in a number different ways. Here are the three simplest methods: 1. Establish that all angles are 90 degrees; 2. Establish that two opposed angles are 90 degrees; and 3. Establish that the diagonals are equally long and intersect one another.
The following transformation matrix can be used to rotate a point (x,y) 90 degrees clockwise with respect to the origin (0,0):
|0 1|\s|-1 0|
This transformation matrix can be applied to each point to determine its new coordinates upon rotation.
Point B is the first point, and its initial coordinates are (-1, 3). The transformation matrix in use:
|0 1| |-1| |3|
|-1 0| x |3| = |-1|
After rotating Point B 90 degrees clockwise, the new coordinates are: (3, -1).
The transformation matrix is then applied to Point C, whose initial coordinates are (2, 1):
|0 1| |2| |1|
|-1 0| x |1| = |-2|
After rotating in a clockwise direction by 90 degrees, Point C's new coordinates are (1, -2).
As a result, after rotating 90 degrees in a clockwise direction around Point 0, Point B's new coordinates are (3, -1), while Point C's new coordinates are (1, -2).

FACE is a rhombus the following measures are 9. CY= 39.05 cm, 10. FC= 40 cm, 11. AY ≈ 39.05 cm, 12. YE = 20 cm, 13. FA ≈ 39.05 cm, 14. AC ≈ 48.99 cm, 15. Perimeter ≈ 156.20 cm.
Describe Rhombus?A rhombus is a quadrilateral with all four sides of equal length. It is also known as a diamond or a lozenge. The opposite sides of a rhombus are parallel to each other, and the diagonals of a rhombus bisect each other at a right angle. Additionally, the diagonals of a rhombus are perpendicular bisectors of each other. This means that they split the rhombus into four congruent right triangles.
Since FACE is a rhombus, all four sides are equal in length. Additionally, the diagonals bisect each other at a right angle, so we can use the Pythagorean theorem to find the lengths of various segments in the figure.
9. CY: Since FC is a diagonal of the rhombus, it bisects angle FCE. This means that triangle FCY is a right triangle with FC as the hypotenuse and FY and CY as the legs. Using the Pythagorean theorem, we can find that CY is:
CY² = FC² - FY²
CY² = 40² - 15²
CY² = 1525
CY ≈ 39.05 cm
10. FC: We already know that FC = 40 cm, since it is one of the diagonals of the rhombus.
11. AY: By symmetry, we know that AY is equal in length to CY, so AY ≈ 39.05 cm.
12. YE: Since YE is half of EA, and we know that EA = 40 cm, we can find that YE = 20 cm.
13. FA: Since all four sides of the rhombus are equal, FA has the same length as CY and AY, so FA ≈ 39.05 cm.
14. AC: Since AC is a diagonal of the rhombus, it bisects angle EAF. This means that triangle ACE is a right triangle with AC as the hypotenuse and AE and EC as the legs. We can use the Pythagorean theorem to find that:
AC² = AE² + EC²
AC² = 40² + 2*(YE)²
AC² = 40² + 2*(20²)
AC² = 1600 + 800
AC² = 2400
AC ≈ 48.99 cm
15. Perimeter of the given rhombus FACE: Since all four sides of the rhombus are equal, we can find the perimeter by multiplying the length of one side by 4. Using any of the values we found above for the length of a side, we get:
Perimeter = 4*CY
Perimeter ≈ 156.20 cm

10. FC = 30 cm
11. AY = 20 cm
12. YE = 20 cm
13. FA = 25 cm
14. AC = 25 cm
15. Perimeter FACE = 100 cm
Step-by-step explanation:
In a rhombus:
All sides of a rhombus are congruent.The diagonals are perpendicular bisectors of each other.Given the diagonals bisect each other, Y is the point of intersection, and CY = 15 cm, then:
[tex]\begin{aligned}\overline{FY} &= \overline{CY} \\&= 15 \; \sf cm\end{aligned}[/tex]
[tex]\begin{aligned}\overline{FC} &= \overline{FY} + \overline{CY} \\&= 15 + 15 \\&= 30 \; \sf cm\end{aligned}[/tex]
Given the diagonals bisect each other, Y is the point of intersection, and EA = 40 cm, then:
[tex]\begin{aligned}\overline{AY}&=\overline{EA} \div 2\\&=40 \div 2\\&=20\; \sf cm\end{aligned}[/tex]
[tex]\begin{aligned}\overline{YE} &= \overline{AY} \\&= 20 \; \sf cm\end{aligned}[/tex]
As the diagonals bisect each other at 90°, m∠FYA = 90°. Therefore, triangle FYA is a right triangle.
As we know the lengths of legs of the triangle FYA, we can use Pythagoras Theorem to calculate the length of the hypotenuse (FA).
[tex]\begin{aligned}\overline{FY}^2+\overline{AY}^2&=\overline{FA}^2\\15^2+20^2&=\overline{FA}^2\\225+400&=\overline{FA}^2\\625&=\overline{FA}^2\\\overline{FA}&=\sqrt{625}\\\overline{FA}&=25\; \sf cm\end{aligned}[/tex]
As the sides of a rhombus are equal in length:
FA = EC = AC = FE = 25 cmThe perimeter of rhombus FACE is the sum of its side lengths:
[tex]\begin{aligned}\sf Perimeter&=\overline{FA}+\overline{EC}+\overline{AC}+\overline{FE}\\&=25+25+25+25\\&=100\; \sf cm\end{aligned}[/tex]

what are the x- and y- coordinates of point P on the directed line segment from A to B such that P is 2/3 the length of the line segment from A to B? x= [m/m+n](x2 -x1) +x1 y = [m/m+n](y2 - y1) +y1
Where m is the distance from A to P and n is the distance from P to B.
What is Length?Length is a measure of distance or size. It is the measurement of the longest dimension of an object, such as a line, segment, or plane. It is commonly used to measure the physical size of objects, as well as the space between them. Length can be measured in many different units, such as meters, feet, or inches. Length is also used to measure the amount of time it takes for something to occur, such as the length of a movie or a song.
Therefore, if the coordinates of A are (x1, y1) and the coordinates of B are (x2, y2), the x- and y- coordinates of point P would be:
x= [2/3(x2 -x1) +x1
y = [2/3](y2 - y1) +y1
This equation can be used to calculate the coordinates of any point P on a directed line segment from A to B such that P is a fraction of the length of the line segment from A to B. By setting the fraction equal to 2/3, we can calculate the coordinates of point P that is 2/3 the length of the line segment from A to B. This can be useful in a variety of applications, such as computer graphics, game design, and engineering. For example, this equation could be used to calculate the coordinates of a point on a line segment that is an exact distance from the two endpoints, or to calculate the coordinates of a point that is a certain percentage of the distance between the two endpoints.

It is commonly used to measure the physical size of objects, as well as the space between them. Length can be measured in many different units, such as meters, feet, or inches.
Given the coordinates of the points A, B and P, we can calculate the x- and y- coordinates of point P such that it is 2/3 the length of the line segment from A to B.
To do this, we need to use the following formula: x = [m/m+n](x2 -x1) +x1, y = [m/m+n](y2 - y1) +y1, where m is 2/3, n is 1/3, x1 and y1 are the x- and y-coordinates of point A, and x2 and y2 are the x- and y-coordinates of point B.
In this case, m = 2/3, n = 1/3, x1 = 2, y1 = -1, x2 = 4, y2 = -3.
Therefore, plugging these values into the formula we get:
x = [2/3](4 -2) +2 = 4
y = [2/3](-3 - (-1)) + (-1) = -2
Therefore, the coordinates of point P such that it is 2/3 the length of the line segment from A to B are (4, -2). Therefore, the correct option is d-(3,-2).

In western music, an octave is divided into 12 pitches. For the film Close Encounters of the Third Kind, director Steven Spielberg asked composer John Williams to write a five-note theme, which aliens would use to communicate with people on Earth. Disregarding rhythm and octave changes, how many five-note themes are possible if no note is repeated?
Answer:
This should be a permutation
Step-by-step explanation:
P (n, r) = n!/(n-r)!
P (12,5) = 12!/(12-5)!
P (12,5) = 12!/7!
P(12,5) = 95040
