The equation showing the relation between shorter and longer skirt is 3s+4t = 140.

Given that the Scottish dance team used 140 yards of tartan to make dancing skirts.

The skirt pattern for the shorter members is 3- yards of fabric, and the skirt pattern for the taller members is 4 yards of fabric.

So, we need to find the equation represents the relationship between the number of short skirts and the number of long skirts that were made,

So, if there are s short skirts and t long skirts,

So,

The relation will be =

3s + 4t = 140

Hence the equation showing the relation between shorter and longer skirt is 3s+4t = 140.

When writing a number greater than or equal to 1 in scientific notation, the exponent of the power of 10 will be positive.

In scientific notation, a number is represented as a coefficient multiplied by a power of 10. For example, the number 12,000 can be written as 1.2 x 10⁴ in scientific notation.

When the number is greater than or equal to 1, the coefficient will be greater than or equal to 1 and less than 10. The exponent of the power of 10 will indicate the number of places the decimal point must be moved to the right to get the original number.

Since the number is greater than or equal to 1, the decimal point must be moved to the right, resulting in a positive exponent. So, when writing a number greater than or equal to 1 in scientific notation, the exponent of the power of 10 will always be positive.

The solution to the trigonometric equation is x = ( 3π/4 ) , x = ( 7π/4 )

Trigonometry is the study of the relationships between the angles and the lengths of the sides of triangles

The six trigonometric functions are sin , cos , tan , cosec , sec and cot

Let the angle be θ , such that

sin (-θ) = -sin (θ)

csc (-θ) = -csc (θ)

cos (-θ) = cos (θ)

sec (-θ) = sec (θ)

tan (-θ) = -tan (θ)

cot (-θ) = -cot (θ)

In the first quadrant, sin, cos and tan are all positive.

In the second quadrant going anti-clockwise, only sin is positive.

In the third quadrant going anti-clockwise, only tan is positive.

In the fourth quadrant going anti-clockwise, only cos is positive

Given data ,

Let the trigonometric equation be represented as A

Now , the value of A is

cot ( x - π/2 ) = 1   be equation (1)

On simplifying the equation , we get

cot ( - ( π/2 - x ) ) = 1

Now , cot (-θ) = -cot (θ)

So , - cot ( π/2 - x ) = 1

And , the value of cot ( π/2 - θ ) = tan θ

Substituting the values in the equation , we get

-tan x = 1 over the interval [ 0 , 2π ]

The value of x for -tan x = 1 is given by x = ( 3π/4 ) + nπ

Answer: To find point Q on the line segment PR that partitions it into the segments PQ and QR in the ratio 4:5, we need to use the concept of proportion.

We can set up the proportion as:

PQ / QR = 4 / 5

To find the actual point Q on the line segment PR, we need to know the coordinates of points P and R. Without them, it is not possible to find the point Q. Once we have the coordinates of P and R, we can use the proportion above to find the coordinates of Q.

Alternatively, we can use the concept of a "partitioned ratio" which is a way to split a line segment into a certain ratio. It is found by adding the two ratios together and then dividing the length of the line segment by that number. In this case (4+5 =9) and then PQ = (4/9) * PR and QR = (5/9) * PR.

The total area of the two triangles is 3 sq units + (-1 sq units) = 2 sq units.

The equation of line a b is y = 2x + 4

and the equation of line d c is y = x + 4

Substituting the y-coordinate of point E, (6) in the equations of line a b and d c, we get:

2x + 4 = 6

x + 4 = 6

Solving the above equations, we get x = 1 and y = 6.

Therefore, the coordinates of point E are (1,6).

The length of side a b is 9 - (2x + 4) = 9 - (2(1) + 4) = 3

The length of side d c is x + 4 - 6 = 1 + 4 - 6 = -1

The length of side a e is 2x + 4 - 6 = 2(1) + 4 - 6 = 2

The length of side d e is x + 4 - 6 = 1 + 4 - 6 = -1

Therefore, the area of triangle a b e is 1/2 (base x height) = 1/2 (3 x 2) = 3 sq units

The area of triangle d c e is 1/2 (base x height) = 1/2 (-1 x 2) = -1 sq units

Therefore, the total area of the two triangles is 3 sq units + (-1 sq units) = 2 sq units.

The standard form of a linear equation in two variables is of the form

Ax + By = C

e.g. 2x-4y=10. Here, x and y are variables, A and B are coefficients and C is a constant.

Now,

What is a Rectangular Prism?

A rectangular prism is a three-dimensional shape that consists of six faces. The two faces are at the top and bottom and the other faces are lateral faces.

The given steps can be divided into 3 rectangular boxes each with length, l = 1 m = 100 cm, width, w = 20 cm, and height, h = 20 cm.

The volume of a rectangular box = l × w × h

= 100 × 20 × 20

= 40000 cm³

Volume of 3 rectangular boxes = 3 × 40000 cm³

= 120000 cm³

Surface area of a rectangular box = 2 (lw + lh + wh)

= 2 [(100 × 20) + (100 × 20) + (20 × 20)]

= 2 [2000 + 2000 + 400]

= 2 [4400]

= 8800 cm²

The surface area of 3 rectangular boxes = 3 × 8800

To determine the number of biking outfits Rashon can buy while staying within his budget, you can set up an inequality using the information provided.

First, calculate the total cost of the reflectors and gloves:

3 reflectors × $10.78 + $32.64 = $38.34 + $32.64 = $71

Then, subtract the cost of the bicycle, reflectors, and gloves from Rashon's budget: $780 - $481.28 - $71 = $227.72

Now, you can use this remaining amount to determine the number of biking outfits Rashon can buy.

Let x be the number of outfits he can buy

You can set up an inequality as follows:

44.95x ≤ $227.72

The required values of u = 21° and v = 2 units in the given triangle.

A triangle is a closed shape composed of three angles, three sides, and three vertices. It is one of the most fundamental geometric forms and is represented by the symbol Δ.

The triangle is given in the shown figure, as follows:

We have to determine the value of u and v

In ΔHGF,

∠G = 67°

∠F = 92°

As we know that the sum of interior angles is always 180 degrees in the triangles.

So, ∠u + ∠G + ∠F = 180°

u +  67° + 92° = 180°

u + 159° = 180°

u = 21°

We can see that the bisector HF divides into equal parts EF and FG.

So, EF = FG

So on solving the provided question, we can say that  A line segment's midpoint is the location where it is divided into two equally sized halves.

The midpoint of a line segment is known as the midpoint in geometry. The centroid of all segments and ends, it is equally spaced from each of them. Add the two figures together and divide by two to determine the middle of any range. Look at this illustration to see how to determine the intersection of two points on a 1D axis. Consider the numbers 5 and 9 as the two points on a number line. Calculating the midpoint is as follows: (5 + 9)/2 = 14/2 = 7. As a result, 7 lies halfway between 5 and 9. There are instances when you need to locate a precise spot between two other points. The term "midpoint" refers to this center. The point on a line segment that divides the line is considered to be the midway of the segment.

A line segment's midpoint is the location where it is divided into two equally sized halves. The point splitting the line segment in any desired ratio can be found using the more potent section formula, which builds on the previous method.

Geometry is a branch of mathematics that deals with shapes, angles, dimensions and sizes of different things we see in everyday life

The interior angles of the quadrilateral are :

180 - (x+16)°          (sum of angles on a straight line)

180 - (3x-1)°           (sum of angles on a straight line)

180 - 6x°              (sum of angles on a straight line)

180 - 5x°              (sum of angles on a straight line)

Since the sum of the interior angles of a quadrilateral is 360°. We have:

180-(x+16)° + 180-(3x-1)° + 180-6x° + 180-5x° = 360°

180 - x - 16 + 180 - 3x + 1 + 180 - 6x + 180 -5x = 360
