If the cost of 40 books is ₹ 360, how much will 30 books cost?

Answers

Answer 1

Answer:

270

Step-by-step explanation:

If the cost of 40 books is ₹ 360, how much will 30 books cost?

we can solve with an equation

40 : 360 = 30 : x

x = 360 * 30 : 40

x = 270 £

or

we find the price of a book and multiply it by 30

360 : 40 * 30 =

9 * 30 =

270 £

Answer:

x = 4

Step-by-step explanation:

Perimeter of triangle: P = (5x -1) + (5x -1) + (2.2x + 10)

Perimeter of square: P = 4(6.5x - 11.8)

so (5x -1) + (5x -1) + (2.2x + 10) = 4(6.5x - 11.8)

5x - 1 + 5x - 1 + 2.2x + 10 = 26x - 47.2

12.2x + 8 = 26x - 47.2

26x - 12.2x = 8 + 47.2

13.8x = 55.2

x = 55.2/13.8 = 4

its say that
(5x-1)+(5x-1)+(2.2x+10) is equal to 4(6.5x-11.8) ***the four represents the four sides of the square***
first u have to simplify so add all the numbers with x and all the numbers without x
12.2x + 8 equals 26x - 47.2
now u have to move the x values on one side and the non values to the other
8+47.2 = 26x-12.2x
so u get
55.2 = 13.8x
now u divide by 13.8 on both sides so u get x
x = 4

Two points have the same y-coordinate but opposite x-coordinates. Which is a possible graph of these points?

Answers

The possible graph for two points have the same y-coordinate but opposite x-coordinates is shown below.

In a general point (x,y) , the value x represents the distance from origin to point along x - axis,

and

the value y represents the distance from origin to point along y axis.

It is given in the question that

There are two points in which the y coordinate of both the points is same

the x coordinate is of opposite signs.

Let us take an Example  

let the points be A(a,b) and B(c,d)

According to the question

b = d and -a = c

So the points will become (a,b) and (-a,b)

Answers

A possible solution for this case of collinear points is (x, AB, BC, CD, AC, AD) = (0, 18, 14, 10, 32, 42).  

What are the lengths of collinear line segments?

In this question we have four points that are collinear, that is, that lie on the same line. Mathematically, speaking we have the following equations representing the geometric system:

BC = 14 + x             (1)

AD = 42 + x           (2)

AC = x + 32           (3)        

By (1) and (3):

AB = (x + 32) - (14 + x)

AB = 18

By (2) and (3):

CD = (42 + x) - (x + 32)

CD = 10

If x = 0, then BC, AD and AC are, respectively:

BC = 14, AD = 42, AC = 32

Answers

The translated vertices of the rhombus are: K(-1,-3), L(3,-1), M(1,-5) and N(-3,-7)

The rhombus is a parallelogram which has all sides equal. the diagonals of a rhombus bisect at right angles. the difference between a rhombus and a square is that none of the angles of a rhombus are 90°.

To translate a figure with given co-ordinates into another figure with a particular translation we simply add or subtract the given values from the coordinates of the available points.

Given co-ordinates of Rhombus are K(-3, 2),L(1, 4),M(-1 ,0)and N(-5, -2).

The translation is given as (x,y) → (x+2, y-5)

So we calculate the coordinates as:

The translated co-ordinate  K(-3, 2)→ K'(-1,-3)

The translated co-ordinate  L(1, 4)→  L'(3,-1)

The translated co-ordinate  M(-1 ,0)→ M'(1,-5)

The translated co-ordinate N(-5, -2)→ N'(-3,-7)

HOWEVER...the teacher wants to go with a three-variable, three-equation system of equations with the format of z = m(x) + n(y) + c for each point.

That would mean the following equations:

How do I proceed from here to get the same answer as the algorithm got?

Answers

The equation of the plane that goes through these points is:

6x + 2y + z = 10.

How to find the equation of a plane given three points?

The equation of the plane is found replacing the points into the following equation:

ax + by + c = z.

For point A, we have that:

3b + c = 4.

For point B, we have that:

a + 2b + c = 0.

For point C, we have that:

-a + 6b + c = 4.

Hence the system is:

3b + c = 4.a + 2b + c = 0.-a + 6b + c = 4.

From the first equation, we have that:

c = 4 - 3b.

Replacing in the second, we have that:

a + 2b + 4 - 3b = 0

a - b = -4.

Replacing in the third, we have that:

-a + 6b + 4 - 3b = 4.

-a + 3b = 0.

a = 3b.

We have that a - b = -4, hence:

3b - b = -4

2b = -4

b = -2.

a = 3b, hence a = -6.

c = 4 - 3b -> c = 10.

Hence the equation is:

ax + by + c = z.

z = -6x - 2y + 10

6x + 2y + z = 10.

What was the airplane's rate of change in elevation?

The rate in change of the elevation will be given by the quotient between the change in elevation and the time in which that change happens.

Here we know that the airplane descended 225 meters, so the change in elevation is:

Retained earnings are usually included in the shareholders' equity portion of a company's balance sheet. Retained earnings are computed by adding beginning-period retained earnings to net income (or loss), then deducting dividend distributions.

How do I figure up my retained earnings?

we have no continuous curve here, the supposed function only consists of a few data pair points. and that is absolutely ok.

any function just maps a set of x (input) values to a set of y (function result) values.

A.

yes, it is a function, because every "used" x value has exactly 1 assigned y value.

when we draw a vertical line and move it across the grid, there are never 2 or more of the points in the line. always only one.

the opposite (every y value has exactly 1 x value as origin) is NOT necessary to be a function. but it would have to be true for the inverse function to be a function too.

B.

the domain is the interval or set of all valid x values.

since we have only single points, it is a set here :

{-4, -3, -2, 0, 2, 3}

C.

the range is the interval or set of all valid y values :

{-3, -1, 0, 2, 3}

D.
