Fraction:

Fractions represent parts of a whole. This whole thing can be a region or a collection. The word break comes from the Latin word "fraction" which means "to divide". The earliest civilization to study fractions, the Egyptians, used fractions to solve mathematical problems such as the division of food, supplies, and the lack of bullion currency.

In ancient Rome, fractions were written to represent parts of a whole using only words. In India, fractions were originally written with the numbers (numerator and denominator) on top of each other, but without lines. Arabs were the only ones who added the dash used to separate the numerator and the denomination.

The scaled copy is bigger that means each side is bigger than the original one or the factor is grater tan 1 as  final length(bigger)/ original > 1

In mathematics, a dilation is the enlargement or contraction of a figure by a predetermined scale factor, k, at or around a center of dilation. It is a transformation style that yields comparable figures.

Depending on the scale factor, the original figure will either enlarge or decrease in size. Scaling, also known as dilations, has no impact on how angles are measured.

The original and updated figures' angles will not change because the size has not changed but the shape has. Preimage and image are two terms that can be used to describe the first and new figures, respectively.

The original figure's vertices are identified with capital letters, such as B, to make it easier to identify between two similar figures.

7 is mean Seven is the average of the times shown on the dot plot as the amount of time it takes to get through the obstacle course.

The mean of a dataset, often termed as the arithmetic mean, is the amount of all values divided by the overall number of values (as opposed to the geometric mean). This is the most often used indicator of central tendency and is frequently referred to as the "mean." This is obtained by dividing the number of values in the dataset by the sum of all the values. Calculations can be performed using either raw data or data that has been integrated into frequency tables. A number's average is referred to as its average. Simple math can be used to determine: After simply adding all the digits, divide by the number of digits. the sum divided by the number.

The four ways to find the midpoint of a line segment are using the Midpoint Formula, using the Distance Formula, using a Graph, and using a Ruler.

Using the Midpoint Formula:

This method involves using the midpoint formula, which is (x1 + x2)/2, (y1 + y2)/2. This formula gives the coordinates of the midpoint when the coordinates of the two endpoints of the line segment are known.

Using the Distance Formula:

This method involves using the distance formula to find the distance between the two endpoints of the line segment and then dividing the distance by 2. The midpoint will be located at the point that is half the distance from each endpoint.

Using a Graph:

This method involves plotting the two endpoints of the line segment on a graph and then drawing a line segment connecting the two points. The midpoint of the line segment will be located at the point where the line segment is bisected.

Using a Ruler:

This method involves measuring the distance between the two endpoints of the line segment with a ruler or measuring tape, and then marking the point that is halfway between the two endpoints. The midpoint of the line segment will be located at the point that is marked.

Acute angles are the angles that measure less than 90 degrees. Right angles measure 90 degrees and Obtuse angles measure more than 90 degrees.

By adding the squares of the triangle's two smaller sides and comparing the result to the square of the largest side, you can determine whether the triangle is acute, right, or obtuse. The triangle is acute because this sum is higher.

A triangle is said to be acute if the squares of its two shorter sides added together exceed those of its longest side. A triangle is considered obtuse if the sum of the squares of its two shorter sides is less than the square of its longest side.

You want to build a structure with a length of 5 m, where the proportions of other dimensions are conserved. Estimate the scale factor, 10 cm / 5 m = 0.02 .

The scale factor is a number that represents the ratio of the measurements of two similar figures, such as geometric shapes or maps. To find the scale factor, you can compare corresponding side lengths or angles of the two figures. The scale factor is the ratio of the length of a side in one figure to the corresponding side in the other figure. You can also find the scale factor by taking the square root of the ratio of the areas or the ratio of the volumes of the two similar figures.

Once you have the scale factor, you can use it to find the missing measurements of a similar figure by multiplying any measurement of one figure by the scale factor. In summary, the scale factor is a numerical value that allows to relate the measurements of two similar figures.

The perimeter of an equilateral triangle is equal to three times the length of the side.  Perimeter = 33 cm and Area =  30.58 cm^2 (√30.58 cm^2)

Perimeter of an equilateral triangle = 3 x side  

=> 3 x 11 cm = 33 cm  

Area of an equilateral triangle = (√3/4) x (side^2)  

=> (√3/4) x (11 cm^2)  

=> (√3/4) x (121 cm^2)  

=> 30.58 cm^2  

=> √30.58 cm^2

The perimeter of an equilateral triangle is equal to three times the length of the side. Therefore, an equilateral triangle with a height of 11 cm will have a perimeter of 33 cm (3 x 11 cm). The area of an equilateral triangle can be calculated using the equation (√3/4) x (side^2). In this case, the area of the triangle is 30.58 cm^2 ((√3/4) x (11 cm^2)).

What is system of equation?

A set or group of equations that are solved collectively is referred to as a system of equations. Both algebraic and visual solutions are possible for these equations. The intersection of two lines represents the system of equations' solution.

For solving the equations graphically, we need to find points for plotting

So, for y = 2x-5,

The y-intercept is -5, so we need to place a point on the graph at (0,-5).  For the another point, put x=1, we get y= -3. So we need to place another point at (1,-3).

Similarly for y = -x-8,

The y-intercept is -8, so we need to place a point on the graph at (0,-8).  For the another point, put x=1, we get y= -9. So we need to place another point at (1,-9).

The solution is the point where the two lines intersect.

When the two lines intersect,
