kai and David share £84 in the ratio 1:3 calculate the amount of money kai gets​

Step-by-step explanation:

If you take the sides you already have, 2, 7, 4, and 3, and add them together, you get 16. Lets take the portion of the perimeter you already have, and lets say this figure is a rectangle.

Divide 16 by 2 to give two sides of the rectangle a portion of the perimeter.
Since the area of a rectangle is width times height, lets create a formula:

8x = 44, 44 being the area, and 8x being the width times the variable of the height.

You get 5.5. for the height of the rectangle.

Add 8+8 to 5.5+5.5
you get 27

Therefore, the value of a for triangle 2 is 44 degrees.

A triangle is a closed geometric shape that has three sides and three angles. It is one of the basic shapes in geometry and is used in many different areas of mathematics and science. The sum of the angles in a triangle is always 180 degrees, and there are many different types of triangles, including equilateral, isosceles, and scalene triangles, depending on the lengths of their sides and the sizes of their angles. Triangles are also commonly used in trigonometry, which is the branch of mathematics that deals with the relationships between the sides and angles of triangles.

Here,

The sum of the interior angles of a triangle is always 180 degrees. Therefore, for triangle 1, we have:

95 + 39 + x = 180

Simplifying the equation, we get:

134 + x = 180

x = 46

For triangle 2, we have:

90 + a + x = 180

Substituting the value of x from above, we get:

90 + a + 46 = 180

Simplifying the equation, we get:

a = 44

Isabella's net worth is $2,725.

We know that the net worth is nothing but a measure of an individual's financial standing at a given point in time.

Here, to calculate the net worth, we need to add up all of the assets and subtract all of her liabilities:

We can see that,

Assets

Car worth: $16,700

Savings account: $4,950

So, the total assets worth:

$16,700 + $4,950 = $21,650

Now liabilities:

Credit card balance: $925

And the rent for the remainder of the lease:

$1,500 x 12 = $18,000 for year

So, the total liabilities would be:

$925 + $18,000 = $18,925

Hence her net worth would be:

21,650 - 18,925 = 2,725 dollars

If the probability of a breakdown on assembly line 'a' is 12% and probability of a breakdown on assembly line 'b' is 16%, then the probability that assembly line 'a' or assembly line 'b' break down is equals to the 26%, i.e., 0.26.

We have the probability of a breakdown on assembly line 'a' = 12% = 0.12

The probability of a breakdown on assembly line 'b' = 16% = 0.16

The probability that both assembly lines break down = 2% = 0.02

Let's two events a breakdown on assembly line 'a' and a breakdown on assembly line 'b' be 'X' and 'Y' respectively. That is P(X) = 0.12, P(Y) = 0.16,

P(X and Y) = P(X∩Y) = 0.02

we have to calculate the probability that assembly line 'a' or assembly line 'b' break down, P( X or Y) = P(X∪Y). Using addition rule of probability, the probability that event A or event B occurs is equal to the probability that A occurs plus the probability that B occurs minus the probability that both occur. So, P( X or Y) = P(X) + P(Y) - P( X∩Y)

The smaller number would be 27. If the first number is 12 greater than the 2nd number and we have to make it equal to 66. Our smaller number would be 27 becuase if we add 12 to 27 that gives us 39. 39+27= 66. Hopefully that makes sense.

The list price of the gift basket is $65.20. This can be determined by taking the total charge of the gift basket ($45.20) and subtracting the shipping charge of $5.50. The remaining $39.70 is the discounted amount of the gift basket.

Since the gift basket was discounted by 30%, the original list price can be determined by dividing the discounted amount by 70%, which is 0.7. Then, the list price can be calculated by multiplying the discounted amount by 1.43 (the reciprocal of 0.7). Therefore, the list price of the gift basket is $65.20.

This method of calculating the list price of the gift basket is called reverse-discounting. The process of reverse-discounting involves subtracting the discounted amount from the total charge to get the original list price. This method is useful when the discount rate is known and the total charge is given. It allows for the original list price of the item to be determined quickly and accurately.

The combined area of the four removed triangles is 48 sq.units. Answer: 48

We need to find out the combined area of the four removed triangles, in square units. Given: AB = 12 units.

Let's consider the given square, and let's draw an altitude BD and also draw perpendiculars to BD from the three vertices A, C and D.

Let AB = x cm. Area of square = x² sq.cm.

Now, we are cutting a triangle with base x and height x, which is a right-angled triangle. Hence, area of each removed triangle = (1/2) * x * x = (x²/2) sq.cm.

Now, BD = x/√2. Area of rectangle = AB * BD = 12 * 12/√2 = 72√2 sq.cm.

Now, area of 4 triangles = (x²/2) + (x²/2) + (x²/2) + (x²/2) = 2x² sq.cm.

We know that, Area of rectangle = Area of 4 triangles + Area of square => 72√2 = 2x² + x² => 72√2 = 3x² => x² = 24√2 cm² => x = √(24 * 2) cm = √(48) cm = 4√3 * √2 cm.

Area of 4 triangles = 2x² sq.cm = 2 * 24 cm² = 48 sq.cm.

Hence, the combined area of the four removed triangles is 48 sq.units. Answer: 48.

The number of iterations increases. If there is a significant difference between the two solutions, we may need to investigate the numerical method used or check for errors in our analytical solution.

Step-by-step explanation:

The differential equation is missing in your question. However, I will give a general overview of how to solve a differential equation numerically using Euler's method and how to find an analytical solution.

Numerical Solution using Euler's Method:

Suppose we have a first-order differential equation of the form y' = f(x, y), where y' represents the derivative of y with respect to x. To solve this numerically using Euler's method, we need to start with an initial condition y(x0) = y0, and we want to find the value of y at some other point x1 = x0 + h.

The Euler's method involves approximating the derivative y' by the difference quotient (y1 - y0) / h, where y1 is the value of y at x1. Rearranging this equation, we get:

y1 = y0 + h * f(x0, y0)

Using this equation, we can iteratively compute the value of y at different points by using the previous value of y. For example, to find y2, we can use the equation:

y2 = y1 + h * f(x1, y1)

We continue this process until we reach the desired endpoint.

Analytical Solution:

An analytical solution to a differential equation is an explicit expression for y(x) that satisfies the differential equation for all values of x. To find an analytical solution, we may use techniques such as separation of variables, integrating factors, or other methods specific to the type of differential equation.

For example, if we have a differential equation of the form y' = k * y, where k is a constant, we can use separation of variables to obtain:

dy / y = k * dx

Integrating both sides, we get:

ln|y| = k * x + C

where C is an arbitrary constant of integration. Solving for y, we get:

y = Ce^(kx)

where C = ±e^C is a constant determined by the initial condition.

Comparison of Solutions:

Once we have the numerical and analytical solutions, we can compare them by plotting the graphs of y(x) for each method. If the numerical solution was computed with a small enough step size, it should converge to the analytical solution as the number of iterations increases. If there is a significant difference between the two solutions, we may need to investigate the numerical method used or check for errors in our analytical solution.

The angle in question measures 60 degrees.

What are supplementary angles?

Supplementary angles are two angles that has sum of 180 degrees. In other words, if you have two angles that are next to each other, and when you add them together, they equal 180 degrees, then those angles are considered to be supplementary.

Let x be the measure of the angle in question.

The supplement of an angle is the angle that, when added to the given angle, results in a sum of 180 degrees. So, the supplement of x is 180 - x.

The problem tells us that the given angle (x) is 120 degrees less than its supplement (180 - x).

Therefore, we can set up the equation:

x = (180 - x) - 120

Total equity after adding the simple interest in the amount will be $825.

What is simple interest?

Simple interest is a type of interest that is calculated only on the principal amount of a loan or investment, without taking into account any interest that may have accumulated in previous periods.

In simple interest, the amount of interest earned or owed is calculated as a percentage of the principal amount, multiplied by the time period for which the interest is being calculated.

simple interest is found using

I = P * r * t

Where I is the amount of interest earned or owed, P is the principal amount, r is the annual interest rate as a decimal, and t is the              time period in years.

Now,

Assuming that the return rate of 10% is a simple annual interest rate, the total equity after one year can be calculated using the formula for simple interest:

Total equity = Principal + Interest

where the interest is calculated as:

Interest = Principal x Rate x Time

In this case, the principal is $750, the rate is 10%, and the time is one year.

Then,

Interest = $750 x 0.10 x 1 = $75

Therefore, the total equity after one year would be:

Total equity = $750 + $75 = $825

σ_mean = σ / sqrt(N)

where σ is the standard deviation of the individual measurements. In this case, the uncertainty of each measurement is given as 1.4 mm, which we can assume is the standard deviation.

To reduce the uncertainty to 0.5 mm, we need

To find the number of machines that minimize the unit cost, we need to find the value of x that minimizes the function C(x). We can do this by finding the critical points of C(x) and determining which one corresponds to a minimum.

First, we take the derivative of C(x) with respect to x:

C'(x) = 1.2x - 372

Then, we set C'(x) equal to zero and solve for x:

1.2x - 372 = 0

1.2x = 372

x = 310

So the critical point is x = 310.

To determine whether this critical point corresponds to a minimum or a maximum, we need to examine the second derivative of C(x):

C''(x) = 1.2

Since C''(x) is positive for all values of x, we know that the critical point x = 310 corresponds to a minimum.

Therefore, the number of machines that must be made to minimize the unit cost is 310.
