Errors in calculations are mistakes or inaccuracies that occur when performing mathematical calculations. They can be caused by a variety of factors, including human error, equipment malfunction, incorrect assumptions or data, and flawed methodology.

There are several types of errors that can occur in calculations, including:

Transcription errors: These occur when a number or a calculation is copied down incorrectly from one place to another, such as from a calculator to a piece of paper.

Calculation errors: These occur when the wrong calculation is used, or when a mistake is made in performing a calculation, such as forgetting to carry a digit when doing long division.

Rounding errors: These occur when numbers are rounded to a certain number of decimal places, and the resulting calculation is not as precise as it could be.

Measurement errors: These occur when the instruments used to measure quantities are not accurate, or when the measurements are not taken correctly.

Conceptual errors: These occur when the underlying concepts or principles of the problem are not fully understood, leading to incorrect calculations.

It is important to identify and correct errors in calculations to ensure the accuracy and validity of the results. Checking calculations multiple times and using multiple methods of verification can help to reduce the risk of errors.

The measure of arc CDE is, 154°

The measure of arc BC is, 26°

The measure of arc AB is, 90°

The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.

Now, By the figure, we have;

⇒ ∠APE + ∠EPD = 180°

⇒ (25x + 15)° + (33x - 9)° = 180°

⇒ 58x + 6 = 180

⇒ 58x = 180 - 6

⇒ 58x = 174

⇒ x = 3

Hence, The measure of arc CDE is,

⇒ (20x + 4)° + (33x - 9)°

⇒ (20×3 + 4)° + (33×3 - 9)°

⇒ 64° + 90°

⇒ 154°

And, The measure of arc BC is,

⇒ 90° - (20x + 4)°

⇒ 90° - (20×3 + 4)°

⇒ 90° - 64°

⇒ 26°

The measure of arc AB is,

⇒ arc AB + 90° = 180°

⇒ arc AB = 90°

In order to solve for x, we need to use the Triangle Angle Sum Theorem, which states that the sum of the angles in a triangle is 180°. Since angle BAC is bisected by segment AD, the two angles must be equal. Therefore, we can set up the following equation to solve for x:

180° = angle BAC = (x + 7) + (x + 18)

We can solve this equation by combining like terms and isolating the variable x.

180° = 2x + 25

Step-by-step explanation:

y = 2x → (1)

y = 2x - 3 → (2)

since both equations express y in terms of . equate the right sides to find any solutions.

2x - 3 = 2x ( add 3 to both sides )

2x = 2x + 3 ( subtract 2x from both sides )

0 = 3 ← false statement

this indicates there are no solutions

The solution to the expression is x = 1/9

From the question, we have the following parameters that can be used in our computation:

27**** = 3³x² x 9​

Express properly

27 = 3³x² * 9​

We can start solving this equation by rearranging it to isolate the variable x:

27 = 243x

Now we divide both sides by 243 to find x

x = 27/243

If the height of a triangle is 2 cm more than base and the area of the triangle is 10 cm then the height is, 7 cm

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

The area of a triangle is given by the formula:

Area = (base x height) / 2

We are given that the area is 10 cm² and that the height is 2 cm more than the base.

Let's call the base "b".

Then, the height is "b + 2".

We can substitute these values into the area formula:

10 = (b x (b + 2)) / 2

Expanding the right side:

10 = (b² + 2b) / 2

Multiplying both sides by 2:

20 = b² + 2b

Subtracting b² from both sides:

20 - b² = 2b

Factoring the left side:

(10 - b)^2 = b²

Taking the square root of both sides:

|10 - b| = b

Adding b to both sides:

10 = 2b

Dividing both sides by 2:

5 = b

So, the base of the triangle is 5 cm and the height is b + 2 = 5 + 2 = 7 cm.

The principal sum of the given compound interest is Rs 5000.

The total amount of money borrowed (or invested), not including any interest or dividends, also called sum.

Given that, a sum of money amounts to Rs. 6050 in 2 year and Rs. 6655 in 3 years. we are asked to find the principal amount or sum,

CI = P(1+r/100)ⁿ

P = principal amount, CI =  compound interest, r = rate, n = time

Therefore,

CI = 6050(1+r/100)²....(i)

CI = 6655(1+r/100)³....(ii)

Diving eq(ii) by eq(i)

6655 / 6050  = (1+r/100)

1+r/100 = 1.1

r/100 = 1.1-1

r/100 = 0.1

r = 10%

Put r = 10% in eq(i)

6050 = p(1.1)²

area of kite = product of the two diagonals

length of one of the diagonals = 2 * KT = 2 * 12 = 24 cm.

the length = 12 + 20.78 = 32.78

area of the kite = 32.78 * 24 = 786.72 square cm

perimeter of the kite
