The Laplace transform table contains properties and formulas for common transforms, as well as the inverse Laplace transform and the shift theorem. It also includes properties such as linearity, scaling, and time shifting.

The Laplace transform table is an important tool for solving linear differential equations. It contains information about common transformations and their associated formulas, as well as the inverse Laplace transform and the shift theorem. The table also includes properties such as linearity, scaling, and time shifting. Linearity states that if a function f(t) is a linear combination of two functions f1(t) and f2(t), then its Laplace transform F(s) is the sum of the Laplace transforms of f1(t) and f2(t). Scaling states that if a function f(t) is multiplied by constant k, then its Laplace transform F(s) is divided by k. Time shifting states that if a function f(t) is shifted by x units in time, then its Laplace transform F(s) is multiplied by [tex]e^(-sx)[/tex]. These properties can be used to simplify Laplace transforms and to solve linear differential equations. The Laplace transform table is a useful tool for engineers and physicists who use linear differential equations in their work.

The formula for percentage error in physics is:

% error = (|experimental value - accepted value| / accepted value) x 100%

In this formula, the experimental value is the measured value obtained from an experiment, the accepted value is the true or theoretical value, and the absolute value of the difference between them represents the error. Dividing this error by the accepted value and multiplying by 100% gives the percentage error.

The percentage error is used to assess the accuracy of experimental measurements and to determine the degree of deviation between the experimental and accepted values. The lower the percentage error, the more accurate the measurement is considered to be.

Answer:

The answer is A

Step-by-step explanation:

200 tiles are required to cover the floor. The cost of tiling at the rate of $7 per tile is ₹ 1200.

A competent mason is installing square tiles with a side of 0. 5 m on the floor of a room that is 10 m long and 5 m broad at a cost of ₹ 6 for each tile.

The entire floor space that has to be tiled is:

Area

= length x width

= 10m x 5m

= 50 square meters

An area of each square tile is:

Area of a square tile

= side x side

= 0.5m x 0.5m

= 0.25 square meters

In order to tile the floor, the following total number of tiles is needed:

Total number of tiles

= Area / Area of a square tile

= 50 / 0.25 = 200

The total cost of tiling the floor at the rate of ₹ 6 per tile is:

Total cost

= Total number of tiles x Cost per tile

= 200 x ₹ 6

= ₹ 1200

So, to tile the floor of the 10m long by 5m broad room with square tiles with a 0.5m side, the professional mason will demand ₹ 1200.

Question- A floor of the room 10 m long and 5 m wide is to be covered by square tiles. If each square tile is 0.5 m, find the number of tiles required to cover the floor. Also, find the cost of tiling at the rate of ₹ 6 per tile.

Step-by-step explanation:

the difference is

1395 - 1200 = $195

how many months until that sums up to $48 750 ?

by checking how often $195 fit into $48,750 :

48750 / 195 = 250

so, it will take 250 months to reach that level.

The perimeter of triangle ΔCBH found using the relationship between similar triangles, ΔCBH, and ΔFEH is 18.9

Similar triangles are triangles that have the same shape and interior angles and between which the ratio of their corresponding sides are equivalent.

The specified parameters are;

The triangles ΔCBH and ΔFEH are similar, ΔCBH ~ ΔFEH

The alternate interior angles theorem indicates that we get;

∠BCH is congruent to ∠EFH and ∠CBH is congruent to ∠FEH

Vertical angles theorem, indicates that we get;

∠CHB ≅ ∠FHE

The ratio of the corresponding sides formed between similar triangles are equivalent, therefore, we get;

CH/FH = BH/EH

7/10 = BH/6

BH = 6 × (7/10) = 4.2

BH = 4.2

CH/FH = BC/EF

7/10 = BC/11

BC = 11 × 7/10 = 7.7

BC = 7.7

The perimeter of the triangle ΔCBH = BC + BH + CH

Therefore, the perimeter of ΔCBH = 7.7 + 4.2 + 7 = 18.9

Answer:

x > 20 is the answer.

Good luck.

If the scale factor of Triangle A to Triangle B is 1:2, it means that the ratio of the corresponding sides of the two triangles is 1:2.

The scale factor is defined as the ratio of the modified change in length to the original length.

Here,

If the scale factor of Triangle A to Triangle B is 1:2, it means that the ratio of the corresponding sides of the two triangles is 1:2.

More specifically, it means that for any given pair of corresponding sides of Triangle A and Triangle B, the length of the side in Triangle B is twice as long as the length of the corresponding side in Triangle A.

For example, if Triangle A has sides of length 3, 4, and 5 units, and Triangle B is similar to Triangle A with a scale factor of 1:2, then the corresponding sides of Triangle B will have lengths of 6, 8, and 10 units.

The speed of the wind is 60 mph.

Let's denote the speed of the wind as r. When the plane is flying with the wind, its speed is (360 + r) mph, and when it's flying against the wind, its speed is (360 - r) mph.

According to the question, the plane flew the same distance with and against the wind, so we can set up an equation:

2.5(360 + r) = 3.5(360 - r)

Expanding the equation, we get:

900 + 2.5r = 1260 - 3.5r

Simplifying and rearranging the terms, we get:

6r = 360

Dividing both sides of the equation by 6, we get:

r = 60

The change in temperature from yesterday to today is -15 degrees Celsius.

Subtraction is a mathematical operation that involves finding the difference between two numbers. In other words, it's the process of removing one number from another number. For example, if you have two numbers, 5 and 3, and you want to find their difference, you would subtract the smaller number (3) from the larger number (5), resulting in the answer of 2. The symbol for subtraction is a minus sign (-). So, the subtraction of 3 from 5 can be written as 5 - 3 = 2.

Here,

The calculation is as follows:

Change in temperature = Today's temperature - Yesterday's temperature

Change in temperature = 0 degrees Celsius - 15 degrees Celsius

Change in temperature = -15 degrees Celsius

Forty-seven and seven tenths minus twenty-three and nineteen-hundredths is equal to twenty-four and fifty-one hundredths, or 24.51 as a decimal.

To find the difference between forty-seven and seven tenths (47.7) and twenty-three and nineteen hundredths (23.19), we can simply subtract the two numbers using the standard subtraction method for decimals. Here are the steps:
1. Line up the decimals:
47.70
-23.19
2. Subtract the hundredths place: 0 - 9 = -9. Since we can't have a negative number in the hundredth place, we need to borrow 1 from the tenths place. So, 10 - 9 = 1.
3. Subtract the tenths place: 6 (after borrowing) - 1 = 5.
4. Subtract the ones place: 7 - 3 = 4.
5. Subtract the tens place: 4 - 2 = 2.
So, the final answer is 24.51.

Therefore, forty-seven and seven tenths minus twenty-three and nineteen-hundredths is equal to twenty-four and fifty-one hundredths, or 24.51 as a decimal.
