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 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

p = 5000

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)°

Step-by-step explanation:

When a negative number is divided by a positive number, the result is always negative.

Let's use the example (-6) / 2 again. We can write this expression as:

(-6) / 2 = (-1) * 6 / 2

We can then simplify the expression on the right-hand side by multiplying -1 and 6, which gives us:

(-1) * 6 / 2 = -6 / 2

Now, we can divide 6 by 2, which gives us:

-6 / 2 = -3

So we see that the quotient is negative.

We can generalize this to any negative number divided by a positive number. Let's say we have a negative number -a and a positive number b. We can write the expression as:

(-a) / b = (-1) * a / b

Multiplying -1 and a gives us:

(-1) * a / b = -a / b

So we see that the quotient is negative, since -1 times a is negative, and dividing a negative number by a positive number results in a negative quotient.

Therefore, we can conclude that when a negative number is divided by a positive number, the result is always negative.

Answer:

there are 100 centigrams in a gram

Step-by-step explanation:

True. Because they have comparable angles, the offered figures are comparable figures.

Similar figures are described as two shapes that share the same shape but differ in size. For instance, similar objects are depicted but are not consistent in different-sized images of a person, such as passport size, stamp size, etc. In geometry, two comparable shapes with different side lengths or sizes are those whose dimensions are equal or have a common ratio. Examples of these shapes are similar triangles, similar rectangles, and similar squares. Scale factor is the name given to the common ratio. The matching angles are also of equal measure.

If two figures are similar, then they are represented by the symbol ‘∼’. Let us say there are two triangles, ABC and PQR, which are similar, then they are represented as;

∆ABC ~ ∆ PQR

Now if the two triangles are similar to each then their corresponding sides should be in proportion. Hence,

AB/PQ = BC/QR = AC/PR

∠A = ∠P, ∠B = ∠Q, ∠C = ∠R

Since, we can see that the angles in both the given figures are exactly the same. Thus, the given figures are similar figures.

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.

Answer: To solve this problem, we can use the Pythagorean theorem. Let's call the depth of the treasure "d".

We can create a right triangle with the following sides:

The sensor on the boat is at the top of the triangle and is 200 meters away from the treasure diagonally.

The line from the sensor to the treasure, which we can call "x", is at a 25-degree angle from the surface of the water.

The line from the treasure to the ocean floor, which we can call "d", is perpendicular to the surface of the water.

Since we know that the angle of depression is 25 degrees, we can use tangent to find the length of x.

tan(25) = x/d

x = d * tan(25)

Now, we have two sides of a right triangle and can use the Pythagorean theorem to find d:

x^2 + d^2 = 200^2

d^2 = 200^2 - x^2

d^2 = 200^2 - (d * tan(25))^2

Solving for d, we find that d = 174.59 meters. Rounding to the nearest tenth of a meter, we get d = 174.6 meters.
