What’s the common denominator of 23/25 and 9/10

The wave is polarized parallel to the y-axis, and the magnetic field lines are parallel to the x-axis. Here option D is the correct answer.

The oscillating electric dipole along the z-axis creates an electromagnetic wave with electric and magnetic fields perpendicular to each other and to the direction of wave propagation. At a position on the y-axis far from the origin, the electric field will be parallel to the y-axis.

The polarization of the wave refers to the orientation of the electric field vector. Since the electric field is parallel to the y-axis, the wave is polarized parallel to the y-axis.

According to the right-hand rule, the direction of the magnetic field lines will be perpendicular to both the electric field and the direction of wave propagation, which is along the z-axis. Therefore, the magnetic field lines will be parallel to the x-axis.

Answer:

Total Amount spent on all the cards = $ 42.3

No of cards  = 16 .

Step-by-step explanation:

The cost is calculated by multiplying the number of items with their costs. As we have different costs for each card we will add the costs of different cards to get the total costs.

Janet buys 3 postcards for $1.05.

Janet spends 3* $1.05= $ 3.15

Rosie buys five postcards for $1.75

Rosie spends 5 * $ 1.75= $ 8.75

Tanya buys eight postcards for $3.80

Tanya spends 8 * $3.80 = $ 30.4

Total Amount spent on all the cards = $ 3.15+$ 8.75+$ 30.4= $ 42.3

No of cards = 3 + 5+ 8= 16 cards were bought .

The value of ML = 3, using the mid-point theorem of triangles.

According to the midpoint theorem, "the line segment of a triangle crossing the midpoints of two sides of the triangle is said to be parallel to its third side and also half the length of the third side."

In the question, we are given that triangle ABC is an equilateral triangle, and L, M, and N are the midpoints of BC, AB, and CA respectively.

Thus, by the midpoint theorem, we can say that:

Assuming AB = BC = AC = x units, we get:

Thus, the triangle LMN is an equilateral triangle.

Thus, MN = ML = NL.

Given MN = 3, we can write the value of ML = 3.

Thus, the value of ML = 3, using the mid-point theorem of triangles.

The unit rate of the Coca-Cola is $ 1.032 and the unit rate of the Pepsi is $ 1.245.

Given, cost of Coca-Cola is

$1.29 for 1.25L

and cost of Pepsi is

$2.49 for 2L

we have to find the unit rate of each of the following,

As, the cost of Coca-Cola is

$1.29 for 1.25L

$1.29 = 1.25L

1 L = 1.29/1.25

1 L = $ 1.032

Now, the cost of Pepsi is

$2.49 for 2L

$2.49 = 2L

1 L = 2.49/2

1 L = $ 1.245

Hence, the unit rate of the Coca-Cola is $ 1.032 and the unit rate of the Pepsi is $ 1.245.

Answer:

12 free throws

10 2-pointers

4 3-pointers

Step-by-step explanation:

Let x = 1 point

y = 2 point

z = 3 point

x + y + z = 26

x = y + 2

x = 3z

Let's make it to where the last two equations are in terms of x

Subtract 2 from both sides of the middle equation

x = y + 2

- 2 - 2

y = x - 2

Divide both sides by 3 in the bottom equation

x/3 = 3z/3

z = x/3

Now plug in the new y and z

x + x - 2 + x/3 = 26

2x + x/3 - 2 = 26

Add 2 to both sides

2x + x/3 - 2 = 26

+ 2 + 2

2x + x/3 = 28

Add up the x terms and don't forget about common denominators

6x/3 + x/3 = 28

7/3x = 28

Multiply both sides by 3/7 to isolate the x variable

(7/3x = 28)3/7

x = 12

Now plug the new x into the original equations to find the remaining variables.

12 = y + 2

- 2 - 2

y = 10

12 = 3z

12/3 = 3z/3

z = 4

The object which is defined using undefined terms of points and lines is option D)

D) Ray

Reason for electing the above option is as follows;

Undefined terms are terms that are not required to be given formal definition in them selves and they include the terms set, plane, line, and point

A point is a dimensionless marker of position and it is indicated in geometry by a capital letter. In geometry, a point is the most elementary entity

A line is an infinitely long and straight geometric object that is defined and named by any two points located on it

A ray is a subset of a line that extends long straight infinitely in one direction, and has a starting point

(b) There are 100 ways for her to distribute the books if they are different and no child gets more than one. Each of the 20 children can receive one of the five different books, so there are 5x4x3x2x1 = 100 possible ways for her to distribute the books.

(c) There are 3,628,800 ways for her to distribute the books if they are all the same and there is no restriction on the number of books that can be given to any child.

Answer:

To find the value of the watch after 30 years, we can use the formula:

V = P(1 + r/n)^(nt)

Where:

V = final value

P = initial value

r = annual interest rate (as a decimal)

n = number of times interest is compounded per year

t = time in years

In this case, P = $8,750, r = 24% = 0.24, n = 1 (compounded annually), and t = 30.

Plugging in the values, we get:

V = 8,750(1 + 0.24/1)^(1*30)

V = 8,750(1.24)^30

V ≈ $407,180.24

Therefore, the value of the watch after 30 years is approximately $407,180.24.

Answer:

$168,735.00.

Step-by-step explanation:

To solve this problem, we can use the formula for compound interest:

A = P(1 + r/n)^(nt)

where A is the final amount, P is the principal (initial amount), r is the annual interest rate as a decimal, n is the number of times the interest is compounded per year, and t is the time in years.

In this case, we have P = $8,750, r = 24% = 0.24, n = 1 (compounded annually), and t = 30 years. Plugging in these values, we get:

A = $8,750(1 + 0.24/1)^(1*30)

A = $8,750(1.24)^30

A = $8,750(19.284)

A = $168,735.00

Therefore, the value of the watch after 30 years is $168,735.00.

The solutions to the original polynomial equation X(x^3-10x^2+28x-24) = 0 are x = 0, x = 2, and x = 6.

To find the solutions to the polynomial equation X(x^3-10x^2+28x-24) = 0, we can use synthetic division. Synthetic division is a method used to divide polynomials by a linear binomial of the form (x - c), where c is a constant.

Let's start by factoring the cubic polynomial x^3 - 10x^2 + 28x - 24. By inspecting the coefficients, we can determine that x = 2 is a root of the polynomial. Using synthetic division, we can divide the polynomial by (x - 2) to obtain a quadratic polynomial.

2 | 1 -10 28 -24

| 2 -16 24

|_________________________

1 -8 12 0

The result of the synthetic division is the quadratic polynomial x^2 - 8x + 12. Now we need to find the roots of this quadratic polynomial. We can either factor it or use the quadratic formula.

Factoring the quadratic equation x^2 - 8x + 12 = 0, we have:

(x - 2)(x - 6) = 0

So the solutions to the quadratic equation are x = 2 and x = 6.

Therefore, the solutions to the original polynomial equation X(x^3-10x^2+28x-24) = 0 are x = 0, x = 2, and x = 6.

Note: Synthetic division is a method used to simplify polynomial division, but it is not applicable to finding all the roots of a polynomial. In this case, we were able to identify one root (x = 2) by inspection and then proceed with synthetic division to simplify the problem.
