find the indicated side of the right triangle 30 7 a=

Answer: 141.78

Step-by-step explanation: 1.39 x 102 = 141.78

Sides AC and DB of the rectangle ABCD are equal to 2x + 13 and 4x – 1, respectively. 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.

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. Similar to how mBDC = 7x + 1 if mADB = 9x - 7 and mBDC = 7x + 1 if mBDC = 7x + 1. Last but not least, mABD = 7x - 31 if mCDB = 4x + 5 and mABD = 7x - 31.

The probability of getting at least two heads is there for 11/16. There are six ways to get two heads and two tales

There are 24 = 16 outcomes in all.

The phrase "at least two heads" is defined as "all outcomes" minus "at most 1 tails": tttt, or httt, thtt, ttht, ttth; that is, 5 ways; the probability of at least two heads is therefore (16-5)/16=11/16.

For instance, two heads: hhtt. How many different ways are there to arrange two h's and two t's? One may naively say 4! (4*3*2*1) However, this treats H and H, T and T as distinct when they are actually one and the same. To make up for this, we divide twice by 2: Probability is 6/16=3/8 since 24/(2*2)=6 ways.

The area for the given quadrilateral will be 5400m^2, Perimeter=300m and no. of rabbits that van fit are 270.

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.

Converting 255 metric minutes as per the defined metric time into standard hours is equal to 2.55 hours.

Using defined metric time we have,

One day is equal to 10 hours

One hour is equal to 100 minutes

One minute is equal to 100 seconds

To convert 255 metric minutes into standard hours we have,

100 minutes = 1 hour

⇒ 1 minutes = ( 1 / 100 ) hour

⇒ 255 metric minutes = ( 255 ) ×  ( 1 / 100 ) hour

⇒ 255 metric minutes = ( 255/ 100 ) hour

⇒ 255 metric minutes = 2.55 hours

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.

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)

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

The nearest thousand, there were an estimated 116,000 wild tigers 20 years ago.

The percentage decrease theory suggests that a decrease in the price of a product or service will lead to an increase in demand for that product or service.

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.

Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have a middle school that took all of its 6th grade students on a field trip to see a symphony at a theater that has 4100 seats. The students filled 2296 of the seats in the theater.

Assume that the theater filled up [x]% of seats at the theater. Then, we can write -

[x]% = (2296/4100) x 100
