The perimeter of the rectangle is 19.93 meter and the area of the rectangle is 22.22 sq. meter.
Here one side of the rectangle is 3( 3/10 ) and the other side is 6 (2/3 ) meter respectively.
Perimeter of the rectangle is 2 ( l + w ) and the Area of the rectangle is (l)*(w), where l is the length and w is the width of the rectangle.
Perimeter = 2(3 3/10 + 6 2/3) = 2(3.3 + 6.666667) = 2(9.96667) = 19.93334 meters
To find the area of a rectangle, we multiply the length by the width. The area of a rectangle with side lengths of 3 3/10 meters and 6 2/3 meters is:
Area = (3 3/10) * (6 2/3) = 3.3 * 6.666667 = 22.222222 square meters
Note that you can convert the mixed numbers to decimals, since it's more convenient to work with decimals when solving arithmetic problems.

What is real image class 10?
When the incident rays appear from a given object, then it is known as a real object. farther, the light rays emanating from the real object after reflection from the mirror, meet at a definite point, then the optically formed duplication of an object is known as an image.
There are two types of images are formed they are real image and virtual image. The real image indicates the representation of an actual object, produced when the light rays arising from a single source intersect at a particular (real) point.
On the opposite, the virtual image can be understood as the image produced due to the apparent separation of rays of light from a definite point.

What is rectangle ?
A rectangle is a type of quadrilateral that has its parallel sides equal to each other and all the four vertices are equal to 90 degrees. Hence, it is also called an equiangular quadrilateral. Since, the opposite sides are equal and parallel, in rectangle, therefore, it can also be termed as a parallelogram.

The triangles are similar. What is the value of x? enter your answer in the box. X = two right triangles. The larger triangle has the long leg labeled 96, the short leg labeled 28, and the hypotenuse labeled 6 x plus 28. The smaller triangle has the long leg labeled 24, the short leg labeled 7, and the hypotenuse labeled 25.
The value of x is 12.
The triangles which are similar have the same shape and measure of three angles are also same. The only thing that varies is their sides. However, the ratio of the sides of one triangle is equivalent to the ratio of the sides of another triangle, which is called here the scale factor.
By dividing the long sides and short sides, find the scale factor:
96 / 24 = 4
28 / 7 = 4
So, the large triangle is four times bigger than the small one.
Now applying the scale factor to calculate the hypotenuse:
The length of the smaller hypotenuse is 25, a scale that by 4 to get 25 * 4 =100
This means that the larger hypotenuse needs to equal 100 and the hypotenuse is labeled 6x +28:
6x+28 = 100
Subtract 28 from each side:
⇒6x = 72
Divide both sides by 6:
⇒x = 72/6
∴x = 12
So, the value of x is 12.

Trigonometric Function:
In mathematics, trigonometric functions (also called circular functions, trigonometric functions, angular functions) are real functions that relate the angles of a right-angled triangle to the ratio of the lengths of its two sides. They are widely used in all geometry-related sciences such as navigation, solid mechanics, celestial mechanics, and geodesy. They are one of the simplest periodic functions and are often used to study periodic phenomena using Fourier analysis.
The most commonly used trigonometric functions in modern mathematics are sine, cosine, and tangent. Their reciprocals are cosecane, secane, and cotangent, respectively, and are seldom used. Each of these six trigonometric functions has a corresponding inverse and a hyperbolic analogue.

Could someone help with 9 and 10?
I’m lost :,)
Answer:
9.) -32 thousand ft per hour
10.) 9/4° per hour
Step-by-step explanation:
9.) To solve this problem, we first need to know the time that the plane landed, which is after 5 hours. Now, we need to find the altitude of the plane a four hours and thirty minutes, which is 16 thousand ft. Lastly, we need to know the formula for rate of change, which is change in y over change in x. Below is the work for how to solve the problem:
change in y / change in x = [tex]\frac{16-0}{4.5-5}[/tex]
[Note: four hours and thirty minutes is equal to 4.5 hours.]
[tex]\frac{16-0}{4.5-5} = \frac{16}{-0.5} =32[/tex]
So, the rate of change from four hours and thirty minutes to when the plane landed is -32 thousand ft per hour.
10.) You did number 10 for the most part, except that the denominator is 8 not 9-0. The reason for this is that is is 8 hours between 6am and 2pm, not 9. This means our final answer is 18/8, or 9/4° per hour.

What is the image of the point (-9,-6) after a rotation of 90 degrees counterclockwise about the origin?
The image of the point (-9, -6) after a rotation of 90 degrees counterclockwise about the origin is (6, -9).
A point in a 2D plane can be represented by its coordinates (x, y).
A rotation of 90 degrees counterclockwise about the origin can be represented by the transformation matrix:
[cos(90) -sin(90)]
[sin(90) cos(90)]
When we apply this transformation matrix to the point (-9, -6), we get the following:
[cos(90) -sin(90)][-9] = [0 * -9 + (-1) * -6] = 6
[sin(90) cos(90)][-6] = [1 * -9 + 0 * -6] = -9
Therefore, the image of the point (-9, -6) after a rotation of 90 degrees counterclockwise about the origin is (6, -9).

The particles contain 5.199 mol. The result is obtained by dividing the number of particles by the Avogadro number.
What is Avogadro number?Avogadro number is the number of particles contained in 1 mol of any substance. It is 6.022 × 10²³ particles/mol.
The number of particles of a substance can be expressed as
N = n × NA
Where
N = Number of particlesn = Number of molesNA = Avogadro numberThe number of particles of a substance is 3.131 × 10²⁴ particles. Find the number of moles!
With the Avogadro number, the number of moles would be
N = n × NA
3.131 × 10²⁴ = n × 6.022 × 10²³
n = (3.131 × 10²⁴) / (6.022 × 10²³)

===================================================
Explanation:
The sequence appears to be geometric. Let's test that claim out.
Divide each term by the previous term.
r = term2/term1 = 62500/312500 = 0.2r = term3/term2 = 12500/62500 = 0.2r = term4/term3 = 2500/12500 = 0.2Each time we get the result 0.2, which is the common ratio r. It tells us this sequence is indeed geometric.
To get the next term in a geometric sequence, we multiply the last term 2500 by this common ratio.
term5 = r*term4 = 0.2*2500 = 500Follow similar steps for terms 6 through 8.
term6 = r*term5 = 0.2*500 = 100term7 = r*term6 = 0.2*100 = 20term8 = r*term7 = 0.2*20 = 4Terms 5 through 8 are 500, 100, 20, and 4 in that order.

A diagonal of a rectangle will intersect the same number of squares as the length of the rectangle. The rectangle has a length of 7 squares and a width of 4 squares, so the diagonal will intersect 12 squares.
A diagonal of a rectangle will always intersect the same number of squares as the length of the rectangle. In this case, the rectangle has been outlined on a grid paper with dimensions of 7x4. This means that the length of the rectangle is 7 squares and the width is 4 squares. Therefore, the diagonal of this rectangle will intersect 12 squares in total. This is because the length of the rectangle is greater than the width and so the diagonal must intersect the entire length of the rectangle and all of the squares the width intersects.
