The product of two numbers is 19,200 and HCF is 40 find the LCM

The length and width of the rectangle is about 33cms and 9cms. This can be calculated with the help of the given area of the rectangle.

Let the original length and width of the rectangle be L and W respectively.

The given area of the rectangle is 297 square cm.

Area = L × B

297 = L × B

As per the question, the length is increased by 3 cm and the width is decreased by 1 cm.

Therefore, the new length and width are L + 3 and W - 1 respectively.

The new area is 3 square cm more than the original area.

So, (L + 3) × (W - 1) = 297 + 3

L×W -L +3W - 303 = 0

297 - L +3W - 303 = 0

-L + 3W - 6 = 0

-297/W + 3W = 6

-297 + 3W² = 6W

W² - 2W - 99 = 0

Using the quadratic formula, we get,

W = -2±[tex]\sqrt{ 2^2 - 4X1 X ( -99 ) ] ) / 2 X1 }[/tex]

[tex]W =\frac{-2±\sqrt{ (4+396)}}{2}[/tex]

[tex]W =\frac{-2±20}{2}[/tex]

Width can't be negative so, W = 9 cm

So, L  297/W

L = 297/9

L = 33cm

Therefore, the length and width of the rectangle are 33 cm and 9 cm respectively.

The statement that is true is: Player 2 has the highest likelihood of getting a hit in their at-bats.

By comparing the probabilities, we can interpret the likelihood of each player getting a hit in their at-bats. The highest probability indicates the highest likelihood of getting a hit.

Comparing the probabilities of the three players, we can see that:

Player 2 has the highest probability (5/8), which means they are the most likely to get a hit in their at-bats.

Player 1 has a lower probability (4/7) than Player 2, but a higher probability than Player 3. This means they are less likely to get a hit than Player 2, but more likely to get a hit than Player 3.

Player 3 has the lowest probability (3/6 = 1/2) of getting a hit, which means they are the least likely to get a hit in their at-bats.

Therefore, the statement that is true is: Player 2 has the   of getting a hit in their at-bats.

As just a motion in the x-direction is needed for this transition, the motion is stiff: d.(x, y) → (x - 2, y) (x - 2, y).

A body's ability to change its location with respect to time is known as motion. The various motions include: 2.1 Straight line motion Particles in linear motion are those that move through one point to the other along a straight or curved path.

a.(x, y) → (2x, y + 2)

As this transformation only comprises a y-direction translation and an x-direction scaling, it is a stiff motion.

b.(x, y) → (2x, 2y)

Since this transformation involves scaling both the x and y axes without any translation, it is a dilation.

c.(x, y) →(x + 2, y + 2)

As this transformation only requires a translation in the x and y dimensions, it is a stiff motion.

Factoring integers with sublinear resources on a superconducting quantum processor can be achieved using quantum approximate optimization algorithm" (QAOA) or quantum phase estimation algorithm (QPE) approach.

Factoring large integers is a problem of significant importance in the field of cryptography.

Classical computers have limited efficiency in solving this problem, and their performance is expected to decline further as the size of the integers to be factored increases.

In contrast, quantum computers are expected to have exponential speedup in factoring large integers, thanks to Shor's algorithm.

Recently, researchers have been exploring the possibility of using superconducting quantum processors to factor integers with sublinear resources.

One approach is to use a so-called "quantum approximate optimization algorithm" (QAOA), which maps the problem of factoring integers to a problem of finding the ground state of a certain Hamiltonian.

The QAOA can be implemented using a superconducting quantum processor, with the problem Hamiltonian implemented by a set of two-qubit gates.

Another approach is to use the quantum phase estimation algorithm (QPE) to estimate the eigenvalues of the problem Hamiltonian.

This can be used to factor integers by finding the period of a certain function using the quantum Fourier transform, as in Shor's algorithm. QPE can be implemented on a superconducting quantum processor using phase estimation circuits, which require only polynomial resources.

The radius of a cylindrical pool when given the volume and height is √{(V / (πh))}.

Cheryl can rewrite the volume formula for a cylinder in terms of the radius.

The volume formula for a cylinder is: V = πr²h

Where V is the volume of the cylinder,

r is the radius of the cylinder,

h is the height of the cylinder.

To determine the radius of the cylindrical pool, we can rearrange the formula for the volume of a cylinder,

V = πr²h, to solve for r.

Starting with the formula for the volume of a cylinder:

V = πr²h

Divide both sides by πh:

V / (πh) = r²

Take the square root of both sides:

√{(V / (πh))} = r

The particular solution to the differential equation is given by: y(t) = y_ h(t) + y_ p(t) = c exp (-5/2 t) + t + 3Here, y_ h(t) is the homogeneous solution, which we don't need to find for this problem.

To solve the given differential equation, we'll need to use the method of undetermined coefficients. In this method, we assume that the particular solution to the differential equation has the same form as the forcing term. Here's how we can solve the given differential equation: Identify the forcing term and its derivatives. The forcing term is given by: f(t) = 68 - 20tWe can find its first derivative as follows: f'(t) = -20We can find its second derivative as follows: f''(t) = Guess the form of the particular solution We assume that the particular solution has the same form as the forcing term.

Since the forcing term is a first-degree polynomial, we assume that the particular solution also has the form of a first-degree polynomial: y_ p(t) = At + B Here, A and B are constants that we need to determine. Find the derivatives of the assumed form of the particular solution. Here are the first and second derivatives of the assumed form of the particular solution: y_ p(t) = At + B ==> y_ p'(t) = A ==> y_ p''(t) = 0. Substitute the assumed form of the particular solution and its derivatives into the differential equation Substituting y_ p(t), y_ p'(t), and y_ p''(t) into the differential equation, we get:8A + 20(At + B) = 68 - 20t Simplifying the above equation, we get: (8A + 20B) + (20A - 20)t = 68Comparing the coefficients of t and the constant terms on both sides,

we get two equations:8A + 20B = 68 (1)20A - 20 = 0 (2)Solving equation (2) for A, we get: A = 1 Substituting A = 1 into equation (1), we get:8 + 20B = 68Solving for B, we get: B = 3. Write the particular solution to the differential equation Substituting A = 1 and B = 3 into the assumed form of the particular solution, we get :y_ p(t) = t + 3Therefore, the particular solution to the differential equation is given by: y(t) = y_ h(t) + y_ p(t) = c exp (-5/2 t) + t + 3Here, y_ h(t) is the homogeneous solution, which we don't need to find for this problem.

The total volume of the sample is 0.0067 m³ and the density of the sample is 2753.73 kg/m³.

An ore sample weighs 18.5 N in air. When the sample is suspended by a light cord and totally immersed in water, the tension in the cord is 11.8 N. When the ore sample is immersed in water, the tension in the cord is given as 11.8 N.

Thus, the buoyancy force experienced by the ore sample is given by the difference between the weight of the sample in the air and the tension in the cord.

Buoyancy force experienced by the ore sample = Weight of the sample in the air - Tension in the cord

Buoyancy force experienced by the ore sample = (18.5 N) - (11.8 N)

Buoyancy force experienced by the ore sample = 6.7 N

Also, we know that the weight of the ore sample in air is equal to the weight of the ore sample when immersed in water.

Weight of the ore sample = Weight of the displaced water

Weight of the ore sample = Buoyancy force experienced by the ore sample

Weight of the ore sample = 6.7 N

The density of the ore sample

Density is given by the formula Density = Mass/Volume

Where Density is measured in kg/m³

Mass is measured in kg

Volume is measured in m³

Also, the density of water is given as 1000 kg/m³.

The density of the ore sample = Mass/Volume

Mass = Density x Volume

Volume of the ore sample can be obtained from volume of the displaced water.

Volume of the displaced water = Weight of the ore sample/Density of water

Volume of the displaced water = (6.7 N)/(1000 kg/m³)

Volume of the displaced water = 0.0067 m³

Density of the ore sample = (18.5 N)/(0.0067 m³)

Density of the ore sample = 2753.73 kg/m³

Let h be the height of the trapezoid.

The area of a trapezoid is given by the formula:

Area = (1/2) × (sum of parallel sides) × (height)

In this case, we know that the area is 21 cm², one base length is 5 cm, and the other base length is 9 cm. So we can write:

21 = (1/2) × (5 + 9) × h

Simplifying this equation, we get:

21 = 7h

Dividing both sides by 7, we get:

h = 3

Therefore, the height of the trapezoid is 3 cm.

Answer:

Step-by-step explanation:

Area of Trapezium is 21 cm². Parallel sides are 5 cm and 9 cm .

Shorter parallel side is 5 cm and the Longer Side is 9 cm.

As we know that formula of area of Trapezium is,

Where,

On substituting the values of area and the two parallel sides in the above formula we will get the required Height.

Substituting the values,

21 = ½ (5 + 9)h

21 = ½ × 14 × h

21 = 7 × h

h = 21/7

h = 3 cm

Therefore, Height of the Trapezium will be 3 cm respectively.

Dorris earns $12.25 in interest over 15 months, while Max earns $2.84 in interest over the same period. So, Dorris earns more interest than Max.

To find out who earns more interest in 15 months, we can calculate the interest earned by each person using the formula:

Interest = Principal x Rate x Time

For Dorris, we have:

Interest = $200 x 0.041 x (15/12)

Interest = $12.25

For Max, we have:

Interest = $300 x 0.019 x (15/12)

Interest = $2.84

Interest refers to the cost of borrowing money, usually expressed as a percentage of the amount borrowed over a specific period of time. When someone borrows money, they are required to pay back not only the amount borrowed but also an additional amount, which is the interest. Interest is how lenders make money and is an important component of the financial system.

There are different types of interest rates, including fixed and variable rates. A fixed interest rate remains the same throughout the loan term, while a variable interest rate may change based on market conditions. Interest rates can also be compounded, which means that interest is added to the principal amount, and future interest payments are calculated based on the new higher amount.
