The rule for divisibility by 9 is similar to divisibility rule for 3. That is, if the sum of digits of the number is divisible by 9, then the number itself is divisible by 9.
What is divisibility?the capacity of being divided. Math. the capacity of being evenly divided, without remainder.
Divisibility rules or Divisibility tests have been mentioned to make the division procedure easier and quicker. If students learn the division rules in Math's or the divisibility tests for 1 to 20, they can solve the problems in a better way. For example, divisibility rules for 13 help us to know which numbers are completely divided by 13. Some numbers like 2, 3, 4, 5 have rules which can be understood easily. But rules for 7, 11, 13, are a little complex and need to be understood in-depth.
Divisibility rule for 10 states that any number whose last digit is 0, is divisible by 10.
Example: 10, 20, 30, 1000, 5000, 60000, etc.
For any given number, to check if it is divisible by 13, we have to add four times of the last digit of the number to the remaining number and repeat the process until you get a two-digit number. Now check if that two-digit number is divisible by 13 or not. If it is divisible, then the given number is divisible by 13.
For example: 2795 → 279 + (5 x 4)
→ 279 + (20)
→ 299
→ 29 + (9 x 4)
→ 29 + 36
→65
Number 65 is divisible by 13, 13 x 5 = 65.

A rectangle is a polygon with four right angles and four sides. Two sides of the rectangle ABCD are AC and DB, with AC equal to 2x + 13 and DB to 4x - 1. Angle BAC is measured by 3x + 1 and angle CAD by x + 15. Angles ABD and CDB are measured as 7x - 31 and 4x + 5, respectively. Angles BDC and ADB are measured as 7x + 1 and 9x – 7 respectively. Angles AEC and AE are measured as 5x - 15 and 3x + 3 respectively.
You can find the missing sides and angles by looking at the rectangle's angles and sides. As an illustration, if AC = 2x + 13 and DB = 4x - 1, then DB = 72. Similar to this, if AC = x + 3 and DB = 3x - 19 then AC = 14. If AE = 3x + 3 and EC = 5x - 15, then AC = 6 is the result. If AE = 4x + 9 and DE = 6x - 7 then DB = 8 is the result.
The measures of the angles can be solved for using the supplied equations. As an illustration, if mDAC = 2x + 4 and mBAC = 3x + 1, then mBAC = 39.

what are quadrilaterals?
A quadrilateral is a polygon with four sides, four vertices, and four angles.
It is formed by joining four non-collinear points. The sum of the interior angles of quadrilaterals is always equal to 360 degrees. The word quadrilateral is derived from the Latin words ‘Quadra’ which means four and ‘Latus’ means ‘sides’. Not all the four sides of a quadrilateral need to be equal in length. Hence, we can have different types of quadrilaterals based on sides and angles.
Five special quadrilaterals are shown below in the image, along with their definitions and pictures, and points for them to get proven.
Now
as given quadrilateral is rectangular in shape because opposite sides are equal and parallel.

How to shade decimal number 0.009 in a base- ten block?Shading decimal numbers in a base-ten block is a great way to visualize numbers in a concrete way. To shade decimal number 0.009 in a base-ten block, start by breaking down the number into its place values. The number 0.009 is equivalent to 9 thousandths, or 0.001. Begin by drawing a base-ten block with four places on the left and one on the right. The four places on the left are labeled hundredths, tenths, ones, and tens respectively. The one place on the right is labeled tenths. Next, shade in the thousandths place, which is the rightmost place on the base-ten block. This will represent the 9 thousandths from 0.009. The thousandths place should be shaded in with a gray or light color. Finally, the remaining places should be left blank, since 0.009 does not have any values in the hundredths, tenths, or ones places. The tenths place should also be left blank. In this way, decimal number 0.009 can be easily visualized in a base-ten block. The thousandths place is shaded in, while the remaining places are left blank.1 tenth | 0 hundredths | 0 thousandths | 9 ten-thousandths

This method ensures that every student has an equal chance of being selected and that the sample is truly random. This is the only method that guarantees that the sample is random and representative of the entire class.
The other methods listed (A, C, D, and E) do not ensure randomness, as they are based on non-random criteria (such as seating arrangement, height, or time of arrival). These methods might introduce bias into the sample and lead to incorrect conclusions about the population.

The exact value of csc(A) is csc(A) = 7/20[√10]
How to determine the value of csc(A)From the question, we have the following parameters that can be used in our computation:
sec(A) = 7/3
Take the inverse of both sides
cos(A) = 3/7
Using the following trigonometry identity, we have
sin²(A) + cos²(A) = 1
Substitute the known values in the above equation, so, we have the following representation
sin²(A) + (3/7)² = 1
So, we have
sin²(A) = 40/49
Take the square roots
sin(A) = ±√(40/49)
The angle is in quadrant II
So, we have
sin(A) = √(40/49)
Take the inverse
csc(A) = √(49/40)
So, we have
csc(A) = 7√(1/40)

This theory is based on the idea that consumers are more likely to buy a product or service if its price is lower. This theory can be applied to both new and existing products or services.
For example, a retailer may decide to decrease the price of a product in order to attract more customers and increase sales. Similarly, a company may choose to reduce the cost of a service in order to make it more attractive to potential customers.
This question is using the percentage decrease theory. According to this theory,
you can calculate the percentage decrease by subtracting the current value from the original value and then dividing by the original value.
Step 1: Subtract the current number of wild tigers (3200) from the original number of wild tigers (20 years ago).
Original - Current = Change
120,000 - 3200 = 116,800
Step 2: Divide the change (116,800) by the original number of wild tigers (120,000)
Change / Original = Percentage Change
116,800 / 120,000 = 97%
Step 3: Multiply the percentage change (97%) by the original number of wild tigers (120,000)
Percentage Change x Original = Estimated Original
97% x 120,000 = 116,400
Therefore, to the nearest thousand, there were an estimated 116,000 wild tigers 20 years ago.

a group of students take hundreds of digital photos for a science project about weather patterns. each photo file contains data representing the level of red, green, and blue for each pixel in the photo. the file also contains metadata that describes the date, time, and geographic location where the photo was taken. for which of the following goals would analyzing the metadata be more appropriate than analyzing the data? select two answers.
Answers
The metadata be more appropriate than analyzing the data is a series of binary digits called bits.
The term called metadata can be defined as the data that provides information about one or more aspects of a given data and it also provide a structured reference that helps to sort and identify all of its attributes such as Author, created Date, modified date, type of the file and the size of the file.
Here we have given that a group of students take hundreds of digital photos for a science project about weather patterns.
And also each photo file contains data representing the level of red, green, and blue for each pixel in the photo.
Where the file also contains metadata that describes the date, time, and geographic location where the photo was taken.
In this scenario, we have to analyze the metadata would be more appropriate than analyzing the data when determining the likelihood that the photo was taken or created at a particular public event.

what is the solution to the system of equations pictured below? (the solution to the system is where the graphs of the two equations intersect.)
Answers
The solution of the system of equations plotted is (x,y) = (4,7).
When a system of linear equations is given, then there exist 3 cases:
Case 1: Unique single solution:
In this case, the lines of the system of equations intersect at one point. That point is the solution of both equations.
The reason we consider intersection as the solution since that the intersection point tells us that it can satisfy both of the given equations simultaneously.
Case 2: No solution:
Then there is no such point that can satisfy both equations simultaneously. Thus, there is no solution to the given system of equations.
Case 3: Infinite number of solutions:
Well, in that case, both the lines are overlapping each other. Thus, all of the points of one line lie on another line too.
And since the given lines are made up of an infinite number of points, thus we will get infinite solutions.
In your case, the lines intersect at points where x=4 and y=7, or say they intersect at coordinate (4,7). Thus, the solution of a given system of equations is x=4 and y=7.
