The discount on the pair of shoes is approximately 14.29%.
In summary, the discount on the pair of shoes is approximately 14.29%.
To calculate the percentage discount, we need to find the difference between the original price and the discounted price. In this case, the original price of the shoes is $84 and the discounted price is $72.
To find the discount amount, we subtract the discounted price from the original price: $84 - $72 = $12.
Next, we need to find the percentage that the discount represents compared to the original price. We can do this by dividing the discount amount by the original price and multiplying by 100: ($12 / $84) * 100 ≈ 0.1429 * 100 ≈ 14.29%.
Therefore, the discount on the pair of shoes is approximately 14.29%. This means that the customer is getting a 14.29% reduction in price compared to the original cost of $84.

A line has a slope of 5/3 and passes through the point (4,6). Write its equation in slope-intercept form.
Write your answer using integers, proper fractions, and improper fractions in simplest form.
Answer:
y = [tex]\frac{5}{3}[/tex] x - [tex]\frac{2}{3}[/tex]
Step-by-step explanation:
the equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
given m = [tex]\frac{5}{3}[/tex] , then
y = [tex]\frac{5}{3}[/tex] x + c ← is the partial equation
to find c substitute (4, 6 ) into the partial equation
6 = [tex]\frac{5}{3}[/tex] (4 ) + c = [tex]\frac{20}{3}[/tex] + c ( subtract [tex]\frac{20}{3}[/tex] from both sides )
[tex]\frac{18}{3}[/tex] - [tex]\frac{20}{3}[/tex] = c , so
c = - [tex]\frac{2}{3}[/tex]
y = [tex]\frac{5}{3}[/tex] x - [tex]\frac{2}{3}[/tex] ← equation of line

What is midpoint formula Class 9?
In class 9, the midpoint formula is a mathematical formula used to find the midpoint of a line segment given the coordinates of its two endpoints. The midpoint formula is:
(x, y) = ( (x1 + x2) / 2, (y1 + y2) / 2)
Where (x1, y1) and (x2, y2) are the coordinates of the two endpoints of the line segment, and (x, y) are the coordinates of the midpoint.
For example, if the coordinates of the two endpoints of a line segment are (3, 4) and (7, 10), you can use the midpoint formula to find the coordinates of the midpoint:
(x, y) = ( (3 + 7) / 2, (4 + 10) / 2)
(x, y) = (5, 7)
So the midpoint of the line segment with endpoints (3, 4) and (7, 10) is (5, 7)
The midpoint formula is used in class 9 to find the midpoint of a line segment in coordinate geometry. It's a simple way to find the point which is exactly in the middle of two given points. It can be used to find the center of a circle if we know the coordinates of two points on the circumference.

Why is a line of longitude called a meridian Class 6?
A line of longitude is called a meridian because it connects the North and South poles and forms a circle around the Earth, like the sun's meridian path during the day.
A line of longitude is an imaginary line that circles the Earth and runs in a north-south direction. It is measured in degrees and divides the Earth into two equal halves, the Eastern Hemisphere and the Western Hemisphere. This line is called a meridian because it is derived from the Latin word meridies which means mid-day or noon. The sun's path across the sky during the day follows a meridian from the North Pole to the South Pole, and this is what inspired the term "meridian" to describe the line of longitude.

Let’s begin with a 30°-60°-90° triangle. A 30°-60°-90° triangle with a hypotenuse of 2 units is shown.
If another right triangle contains a 30° or a 60° angle but is a different size, what can you say about the side lengths of that triangle in terms of the given triangle? Explain your answer.
The side lengths of the new right triangle can be determined by the ratio of the given triangle.
What is triangle?A triangle is a three-sided polygon with three straight sides that are connected at three corners. It is one of the most basic shapes in geometry and is found in many areas of mathematics. Triangles can be classified according to their angles, sides, and size. They can be equilateral, isosceles, or scalene, depending on the size of their angles and sides. Triangles are used in a variety of fields, including architecture, engineering, construction, art, and design.
The side opposite the 30° angle will always be half the length of the hypotenuse, while the side opposite the 60° angle will always be equal to the square root of three times the length of the side opposite the 30° angle. This means that if the hypotenuse of the given triangle is 2, then the side opposite the 30° angle will be 1 and the side opposite the 60° angle will be √3.
Therefore, for any other right triangle containing a 30° or a 60° angle, the side length can be found by multiplying the side length of the given triangle by the same ratio. For example, if the hypotenuse of the new triangle is 6, then the side opposite the 30° angle will be 3 and the side opposite the 60° angle will be 3√3.
In conclusion, for any right triangle containing a 30° or a 60° angle, the side lengths can be determined by multiplying the side lengths of the given triangle by the same ratio.

A cubical box of cardboard has an edge 4.8 m long. how many closed cuboidal boxes of dimension 24 cm×12cm×10cm can be made out of it
Answer
38,400
Step by Step Explanation
Firstly we have to get the volume of the cube box in cm³ which is 480³ = 110,592,000
Secondly we have to get the volume of the cuboid in cm³ too which is 24×12×10 = 2,880
And lastly, 110,592,000/2,880 = 38,400
The number of closed cuboidal boxes is 38400.
Side of the Cubical Box, a = 4.8 m
Using the formula,
Volume of a cube: V = a³
V1 = a³
V1 = (4.8)³
V1 = 110.59 m³
Dimension of Cuboidal Boxes,
Length, l = 24 cm
Breadth, b = 12 cm
Height, h = 10 cm
Using the formula,
Volume of cuboid : V = l × b × h
V2 = l × b × h
V2 = 24 × 12 × 10
V2 = 2880 cm³ or 0.0028m³
Number of closed cuboidal boxes,

What kind of function is an exponential function?
An exponential function is a function in which the variable (usually represented by "x") is the exponent, rather than the base.
The most common form of an exponential function is f(x) = b^x, where b is a positive constant known as the base of the function.
Exponential functions can take many different forms, but they all have one thing in common: the variable is in the exponent. In most cases, the base of the function is a positive constant, and the exponent is the input variable. Exponential functions can also be used to model a wide variety of real-world phenomena, such as population growth, compound interest, and decay of radioactive materials.
The graph of an exponential function is always a smooth curve that increases or decreases at an increasing rate. The slope of the curve increases as x increases, which means that the rate of change of the function also increases as x increases.
