Based on the calculation, we get that the cost of the watch is Rs 22.50.

Cost is the amount of resources, time, money, or effort that must be expended to achieve a goal or achieve something. It can refer to the financial or monetary expense of something, but it can also refer to other types of resources or effort that must be invested.

Let C be the cost of the watch.

The profit that Sakhi made on the watch was 15% of C. We can express this as:

Profit = (15/100) * C

If Sakhi had bought the watch at 10% less than the price at which he sold it and sold it for Rs. 28 le, he would have gained 20% on the sale. We can express this as:

Profit = (20/100) * (C - (10/100) * C)

We can set these two expressions for profit equal to each other and solve for C:

(15/100) * C = (20/100) * (C - (10/100) * C)

This simplifies to:

15/100 = 20/100 - (10/100)^2

Which simplifies to:

15 = 20 - (10/100)

Solving for C, we find that the cost of the watch is:

C = Rs. 22.50

Therefore, the cost of the watch is Rs. 22.50.

The missing part in the question is shown below.

Linear graph equations are one-degree equations. It is a straight-line equation. A linear equation with parameters a and b equal to zero has the conventional form ax + by + c = 0.

How do one express the standard form of a linear equation?

A linear equation has the following standard form: ax + by + c = 0.

Here, variables x and y and constants a, b, and c are used.

Also, a ≠ 0, and b ≠ 0.

For linear equations, the slope-intercept formula is: y=mx+b

Where m stands for the line's slope and b represents the y-intercept.

The three types of linear equations are point-slope, slope-intercept, and standard form.

When an algebraic equation is graphed, it always produces a straight line since each term has an exponent of 1 or 0. This type of equation is known as a linear equation.

Steps of drawing linear graphs are described below:

Step 1: Using the provided linear equation, determine the value of y with respect to x.

Step 2: Arrange these data in a table format.

Step 3: Create a graph using the points from the database.

Step 4: Connect the points to form a straight line.

The slope if it is perpendicular is [tex]-\frac{1}{m}[/tex].

What is slope ?

The slope of a line is a measure of its steepness. Mathematically, slope is calculated as "rise over run" (change in y divided by change in x).

What is perpendicular ?

The word perpendicular means at right angles and this is because when two lines meet, they form right angles. Perpendicular lines can face in any direction such as up and down, crossways, and side-to-side.

Let y = 3x + 1 is perpendicular ,

differentiate respect of x

[tex]\frac{dy}{dx} = 3[/tex] , m = 3

Thus , [tex]-\frac{1}{m}[/tex]

The correct sentence is C, "-3 > -8."

Here's how you can determine which sentence is correct:

In sentence A, -3 is not greater than 2, so sentence A is incorrect.

In sentence B, -3 is not less than -6, so sentence B is incorrect.

In sentence C, -3 is indeed greater than -8, so sentence C is correct.

In sentence D, -3 is not greater than -2, so sentence D is incorrect.

Remember that when comparing two negative numbers, the one with the smaller absolute value is the larger negative number. For example, -8 is a larger negative number than -3 because -8 is closer to 0 (which is the smallest possible number). Similarly, -2 is a larger negative number than -3 because -2 is closer to 0.

So, y = (1/2)(x + 8) is the equation of the linear function.

To write the equation of a linear function with a given x-intercept and y-intercept, we can use the point-slope form of a linear equation:

y - y1 = m(x - x1)

In this case, we are given that the x-intercept is (-8, 0) and the y-intercept is (0, 4). We can use the coordinates of the x-intercept as (x1, y1) and the slope of the line as m to write the equation:

y - 0 = m(x - (-8))

y = m(x + 8)

We can then substitute the y-intercept into this equation to find the value of m:

4 = m(0 + 8)

4 = 8m

m = 1/2

Substituting the value of m back into the equation, we get:

y = (1/2)(x + 8)

This is the equation of the linear function.

Step-by-step explanation:

Given 64 feet of fencing that can be used for three sides of a rectangular enclosure next to a barn wall, you want a function for area in terms of enclosure width, the width that maximizes area, and the maximum area.

If we define the width (x) as the dimension parallel to the barn wall, then the fence available for the "height" (out from the barn wall) is (64-x) in length. Half that is used on either end of the enclosure, so the area is ...

  A = WH

  A(x) = x(64 -x)/2

We notice this function describes a parabola that opens downward, with zeros at x=0 and x=64. The vertex (maximum) is on the line of symmetry, halfway between the zeros:

  x = (0 +64)/2 = 32

The width that maximizes area is x = 32 ft.

Using x=32 in the area formula, we find the maximum area to be ...

  A(32) = 32(64 -32)/2 = 1024/2 = 512 . . . . square feet

The maximum area is 512 square feet.

The axis of symmetry is a straight line that makes the shape of the object symmetrical. The axis of symmetry creates the exact reflections on each of its sides.

Given that, draw line segment AB and find its axis of symmetry​

Let's first draw a line segment of length 7.3 cm.

1) Draw a line l, mark point A on it.

2) Since length is 7.3 cm, we measure 7.3 cm using ruler and compass.

3) Now, keeping compass opened the same length, we keep pointed end at point A and draw an arc on line l.

So, the required line segment is AB = 7.3 cm.

Now, we need to find its axis of symmetry.

1) Given a line segment AB.

2) Now with A as centre, and radius more than half AB, draw an arc on top and bottom of AB.

3) Now with B as centre, and same radius, draw an arc on top and bottom of AB.

4) Where the two arcs intersect above AB is point C and where the two arcs intersect below AB is point D.

To describe both sides of right triangles, we utilize specific terminology. The side opposing its right angle is always the tangent of a right triangle.

The circumference of a circle is given by the formula $C = 2\pi r$, where $r$ is the radius of the circle. In this case, the circumference of the circle is $13\pi$ cm, so we can set up the equation $13\pi = 2\pi r$ to solve for the radius. Dividing both sides by $2\pi$, we get $r = \frac{13\pi}{2\pi} = \frac{13}{2}$ cm. The area of a circle is given by the formula $A = \pi r^2$, so the area of this circle is $A = \pi \left(\frac{13}{2}\right)^2 = \frac{169}{4}\pi$ square cm. Therefore, the area of the circle is $\frac{169}{4}\pi$ square cm.

The same attribute is expressed using a unit conversion but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometers, feet, or any other measurement unit instead of miles.

We know we can convert temperatures from celsius to fahrenheite or from fahrenheite to celsius.

The conversion of celsius to fahrenheit is given by the formula,

C = (5/9)(F - 32).

Now, we have to solve for F.

C = (5/9)F - (160/9).

Now to get rid of the fraction we'll multiply 9 to each term.
