What is the arithmetic operation?

The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or more quantities. Included in them is the study of numbers, especially the order of operations, which is important for all other areas of mathematics, including algebra, data management, and geometry. The rules of arithmetic operations are required in order to answer the problem.

Let the Bethan's income be x

Amrit's income is 32% more than Bethan's income.

So, Amrit's income=x+32%

Amrit and Bethan's combined income is £54868.

According to given question we have

x+x+32%=£54868

2x+32/100=£54868

2x=54868-0.32

2x=54867.68

x=27433.84

Bethan's income=£ 27433.84

Amrit's income

=x+32%

=£ 27433.84+0.32

=£27434.16

Therefore,  Amrit's income is £27434.16.

Long division is a method of dividing large numbers by hand. It can be done using several different methods, but the standard algorithm is the most common.

The steps for the standard algorithm are as follows:

1. Begin by writing the dividend (the number to be divided) above the division bar and the divisor (the number that the dividend is being divided by) below the division bar.

2. Divide the leftmost digit of the dividend by the divisor. Write the result of this division to the left of the division bar.

3. Multiply the divisor by the quotient from the previous step, and write the result of this multiplication below the dividend.

4. Subtract the product from the dividend and write the result below the dividend.

5. Bring down the next digit of the dividend to the remainder and repeat steps 2-4 until the remainder is 0.

6. The result of the division is the quotient written to the left of the division bar.

Step-by-step explanation:

According to the question the maximum error in the calculated area of the rectangle is \(\(4.7 \, \text{cm}^2\).\)

Step 1: The area of the rectangle is given by the formula:

\(\[A = xy\]\)

To estimate the maximum error in the calculated area, we can use differentials. Let's denote the length and width measurements as \(\(x\) and \(y\)\), respectively, and the corresponding maximum errors as \(\(\Delta x\) and \(\Delta y\).\)

Step 2: Express the area as a function of \(\(x\) and \(y\):\)

\(\[A = xy\]\)

Step 3: Take the differential of the area with respect to \(\(x\):\)

\(\[dA = \frac{\partial A}{\partial x} dx + \frac{\partial A}{\partial y} dy\]\)

Since \(\(\frac{\partial A}{\partial y}\)\) is 0 because the area does not directly depend on \(\(y\)\), the equation simplifies to:

\(\[dA = \frac{\partial A}{\partial x} dx\]\)

Step 4: Find \(\(\frac{\partial A}{\partial x}\)\) by differentiating the area function:

\(\[\frac{\partial A}{\partial x} = y\]\)

Step 5: Substitute the given values into the equation:

\(\[\Delta A = \frac{\partial A}{\partial x} \Delta x\]\)

\(\[\Delta A = y \Delta x\]\)

Step 6: Substitute the measured values for \(\(y\) and \(\Delta x\):\)

\(\[\Delta A = (47 \, \text{cm})(0.1 \, \text{cm})\]\)

Step 7: Calculate the maximum error in the area:

\(\[\Delta A = 4.7 \, \text{cm}^2\]\)

Therefore, the maximum error in the calculated area of the rectangle is \(\(4.7 \, \text{cm}^2\).\)

Answer:

y = 3x - 10

Step-by-step explanation:

Answer:

y = 3x -10

Step-by-step explanation:

Slope intercept form is y = mx+b  where m is the slope and b is the y intercept

-9x +3y =-30

Add 9x from each side

-9x+9x +3y =9x-30

3y = 9x-30

Divide each side by 3

3y/3 = 9x/3 -30/3

y = 3x -10

There are 3080 ways 3 men and 2 women can be chosen if they are equally considered, using the multiplication principle of counting

The multiplication principle states that if there are m ways to perform one task and n ways to perform another task, then there are m x n ways to perform both tasks together.

To find the number of ways to choose 3 men from the 12 men, we can use the formula for combination, which is: ⁿCᵣ = n! / (r! (n-r)!).

where n is the total number of men and r is the number of men chosen

so, the number of ways to choose 3 men from the 12 men = ¹²C₃ = 1.

Similarly, we evaluate the number of ways to choose 2 women from the 8 women

as = ⁸C₂ = 14

Now, using the multiplication principle, we can find the total number of ways 3 men and 2 women be chosen if they are equally considered.

220 x 14 = 3080

Therefore, there are 3080 ways 3 men and 2 women can be chosen if they are equally considered, using the multiplication principle of counting

BC ≈ 14.4 mm

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

BC² = AB² + AC² = 2.6² + 14.2² = 6.76 + 201.64 = 208.4

Take the square root of both sides

BC = \(\sqrt{208.4}\) ≈14.4 mm ( to 1 dec. place )

the main answer is that the mean value of the activity time is 21.67. This is calculated using the formula (optimistic + 4 * most likely + pessimistic) / 6.

To find the mean value of the activity time, we can use the three estimates provided: optimistic, most likely, and pessimistic time.

1. The optimistic time is the shortest possible time for completing the activity, which is 11 units.
2. The most likely time is the time that is most likely to be taken to complete the activity, which is 21 units.
3. The pessimistic time is the longest possible time for completing the activity, which is 35 units.

To calculate the mean value, we can use the following formula:
Mean value = (optimistic + 4 * most likely + pessimistic) / 6

Substituting the given values, we get:
Mean value = (11 + 4 * 21 + 35) / 6

Calculating the numerator first:
11 + 4 * 21 + 35 = 11 + 84 + 35 = 130

Now, we can calculate the mean value:
Mean value = 130 / 6

Dividing 130 by 6, we get:
Mean value = 21.67 (rounded to two decimal places)

Therefore, the mean value of the activity time is 21.67.

the main answer is that the mean value of the activity time is 21.67. This is calculated using the formula (optimistic + 4 * most likely + pessimistic) / 6.

The equation of a line y=2x+8.

The equation of a straight line can be represented in the slope-intercept form, y = mx + c

Where c = intercept

Slope, m =change in the value of y on the vertical axis/change in the value of x on the horizontal axis

Looking at the given line,

y = 2x + 7

Compared with the slope-intercept equation,

Slope, m = 2

If a line is parallel to another line, it means that both lines have equal or the same slope. This means that the slope of the line passing through the point (-2, 4) is 2

Substituting m= 2, y = 4 and x = -2 into the equation, y = mx + c , it becomes

4 = 2 × - 2 + c

4 = - 4 + c

c = 4 + 4 = 8

A. the graph is a straight line with slope 1.  It goes up/down infinitely far so the range is all real numbers.  Not A!

B. The graph is a straight line with slope -4, so, like the function in A, the range is all real numbers.  Not B!

D. The graph is an absolute value function  y = |x|, reflected over the x-axis, shifted right 3 units, then shifted down 4 units.  So the graph starts witha "vee" shape opening up, becomes a vee opening down, then ultimately gets shifted down 4 units.  The range is all real numbers less than or equal to -4.

The volume for the largest box will be 1.056 foot³. This can find out by application of differentiation.

What is AOD?

AOD is nothing but application of differentiation. It implies scopes where we can use differentiation to make our calculations easy.

Here, given

Length and breadth = 2,3 foot

Let us consider length of side of square = x

So, after cutting squares left sides of rectangular sheet = 2-2x , 3-2x

So, volume = (2-2x)*(3-2x)*x

                v = 4x³ - 10x² + 6x

To find largest volume , \(\frac{dv}{dx}\) = 0

                 \(\frac{dv}{dx}\) = 12x² - 20x + 6

                12x² - 20x + 6 = 0

                x = 0.4 , 1.3

The heat released per gram of KCl is -238.1 J/g.

To calculate the heat absorbed by the water and the calorimeter, we can use the formula:

q = m * c * ΔT

where q is the heat absorbed or released, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.

First, we need to calculate the heat absorbed by the water:

q_water = m_water * c_water * ΔT_water

m_water = 75 g (mass of water)

c_water = 4.184 J/g°C (specific heat capacity of water)

ΔT_water = 31°C - 21.6°C = 9.4°C

q_water = 75 g * 4.184 J/g°C * 9.4°C = 2811.9 J

Next, we need to calculate the heat absorbed by the calorimeter:

q_calorimeter = c_calorimeter * ΔT_calorimeter

We assume the calorimeter has negligible mass, and its specific heat capacity is known. Therefore, we can use this simplified formula.

c_calorimeter = 25 J/°C (specific heat capacity of the calorimeter)

ΔT_calorimeter = 9.4°C

q_calorimeter = 25 J/°C * 9.4°C = 235 J

Finally, we can calculate the heat released by the KCl:

q_KCl = -q_water - q_calorimeter

q_KCl = -(2811.9 J + 235 J) = -3046.9 J

The negative sign indicates that heat is released by the KCl.

Now, we can calculate the heat released per gram of KCl:

heat_per_gram_KCl = q_KCl / m_KCl

m_KCl = 12.8 g (mass of KCl)

heat_per_gram_KCl = -3046.9 J / 12.8 g = -238.1 J/g

The heat released per gram of KCl is -238.1 J/g.
