A father is giving 1/6 of his money to son A, and 1/7 of his money to son B. Son C gets 29400. How much does son A get?

The height, ab, is 6 cm

The volume of the pyramid is 100 cm3.

we know that

ABC is a right triangle and we know that

∠ACB=45°

AC=hypotenuse------ 6√2 cm

sin 45=AB/AC----- AB=AC*sin 45----> AB=6√2*√2/2----> AB=6 cm

AB=6 cm

we already know that the formula for getting the volume of a pyramid

volume of the pyramid=(1/3)*Area of the base*height

We will now Substitute all the values in the formula;

area of the base=50 cm²

height=6 cm

so

volume of the pyramid=(1/3)*50*6---->

The slope of the lines in the question are 0 and -1/2

Slope of a line is the change in y-coordinate with respect to the change in x-coordinate.

The net change in y-coordinate is represented by Δy and the net change in x-coordinate is represented by Δx.

Hence, the change in y-coordinate with respect to the change in x-coordinate is given by,

m = y₂ - y₁ / x₂ - x₁

a)

Taking the two points;

m = 7 - 7 / 5 - (-1)

m = 0

The slope is equal to 0

b)

Using the same formula above;

m = y₂ - y₁ / x₂ - x₁

m = 0 - 2 / 5 - 1

m = -2 / 4

m = -1/2

The slopes are 0 and -1/2

The angle between two lines having slopes as 1 and 1 is 0°. thus, the two lines coincide with each other.

The formula to find the angle between two lines having slop m1 and m2 is

tan θ= ± (m2 – m1 ) / (1+m1m2)

Substituting the value of slope in this equation

tan θ = ± (1-1)/ (1 + 1×1)

tan  θ =± 0

 θ=   [tex]tan^{-} (0)[/tex]

θ = 0°

When two straight lines cross, two sets of angles are created. The intersection creates two acute angles and two obtuse angles. The slopes of the intersecting lines have an impact on the angles' absolute values.

It is also important to note that because the slope of a line parallel to the y-axis is indeterminate, it is impossible to calculate the angle created by two lines intersecting.

Using the equation we know that the flowerbed is 2250 feet away from the hive.

A mathematical assertion that has an "equal to" symbol between two expressions with equal values is known as an equation.

As in 3x + 5 Equals 15, for instance.

So, let's say the flowerbed is feet away from the hive.

The bee travels directly from its hive at a speed of 20 feet per second to a flowerbed before returning at a speed of 12 feet per second.

Time = distance/speed

Therefore, the bee needed x/20 seconds to get to the flowerbed and x/12 seconds to fly back to the hive.

The bee spends a total of 20 minutes, or 2060 seconds, or 1200 seconds away from the hive. I

t spends 15 minutes, or 1560 seconds, at the flowerbed.

Consequently, the equation will be:

x/20 + x/12 + 900 = 1200

3x + 5x/60 = 300

8x = 60 * 300

8x = 18000

x =  18000/8

x = 22550

Therefore, using the equation we know that the flowerbed is 2250 feet away from the hive.

The area of the rectangle in centimeter square is 2013 cm².

The area of a rectangle is the product of its length and width.

If the values of area and one of the sides of a rectangle is given the other one can be found by forming a suitable equation.

The length and width of the given rectangle can be written in cm as follows,

The length is given as 24 × 2.54 = 60.96 cm

And, the width is 13 × 2.54 = 33.02 cm

Now, the area of the rectangle can be obtained by taking the product of length and width as follows,

Area = 60.96 × 33.02

        = 2012.89

Which can be approximated as 2013 cm².

Hence, the area of the rectangle is obtained as 2013 cm².

Answer:

Sure! The formula for simple interest is I = P x R x T, where I is the interest, P is the principal, R is the interest rate, and T is the time.

To find the interest, you would plug in the values for P, R, and T and solve the equation. For example, if you have a principal of $500, an interest rate of 10%, and a time of 5 years, the formula would look like this: I = 500 x 0.1 x 5 = $250.

To find the principal, you would rearrange the formula to solve for P. This would give you P = I / (R x T). Using the same values as before, the formula would look like this: P = 250 / (0.1 x 5) = $500.

To find the interest rate, you would rearrange the formula to solve for R. This would give you R = I / (P x T). Using the same values as before, the formula would look like this: R = 250 / (500 x 5) = 0.1.

To find the time, you would rearrange the formula to solve for T. This would give you T = I / (P x R). Using the same values as before, the formula would look like this: T = 250 / (500 x 0.1) = 5.

If X is a normally distributed random variable and X ~ N(μ, σ), then the z-score is:                              z = x−μ/ σ

The z-score indicates the number of standard deviations that the value x is above (right) or below (left) the mean μ. Values ​​of x greater than the mean have positive z values, and values ​​of x less than the mean have negative z values. The z-score of x is zero if x is equal to the mean.

The standard normal distribution is the normal distribution of standardized values ​​called z-scores. Z-scores are measured in units of standard deviation. For example, if the normal distribution has a mean of 5 and a standard deviation of 2, then the value 11 is 3 standard deviations above (or to the right of) the mean. Here's the calculation:

                      x = μ + (z)(σ)  

                         = 5 + (3)(2)

                         = 11

The standard normal distribution has zero mean and one standard deviation. The transformation

                                    z= x − μ/σ

gives the distribution Z ~ N(0, 1). The value x comes from a normal distribution with mean μ and standard deviation σ.

The next two videos explain what it means to have a "normal" distributed data set.

If X is a random variable and follows a normal distribution with mean µ and standard deviation σ, the rule of thumb states within 1 standard deviation of the mean.

About 95% of the x-values ​​lie between –2σ and +2σ of the mean µ (within two standard deviations of the mean).

About 99.7% of the x-values ​​lie between –3σ and +3σ of the mean μ (within 3 standard deviations of the mean) .

Almost all x-values ​​are within 3 standard deviations of the mean.

1) +1σ and -1σ have z-scores of +1 and -1 respectively.

2) +2σ and -2σ have Z-scores of +2 and -2 respectively.

3) +3σ and -3σ have Z-scores of +3 and -3 respectively.

The rule of thumb is also known as the 68-95-99.7 rule.

The exact value used to calculate the median; further decreasing the minimum value or increasing the maximum value will not change the median value. Therefore, the median does not use all the information in the data and is therefore shown to be less efficient than the mean or average, which uses all the values ​​in the data.

After solving the given equation 3(-2x - 1) = 2(x + 5), we know that the value of x is (A) -13/8.

A mathematical statement known as an equation is made up of two expressions joined together by the equal sign.

A formula would be 3x - 5 = 16, for instance.

When this equation is solved, we discover that the value of the variable x is 7.

The point-slope form, standard form, and slope-intercept form are the three main types of linear equations.

So, we got the equation:

3(-2x - 1) = 2(x + 5)

Now, solve for x as follows:

3(-2x - 1) = 2(x + 5)

-6x - 3 = 2x + 10

-6x - 2x = 10 + 3

-8x = 10

x = -13/8

Therefore, after solving the given equation 3(-2x - 1) = 2(x + 5), we know that the value of x is (A) -13/8.

Fourth blank: 1,700 feet.

Wen two triangles have a pair of included congruent angles and two pairs of corresponding congruent sides, then both triangles are congruent to each other by the side-angle-side theorem.

Furthermore, if two triangles are known to be congruent to each other, the CPCTC states that "corresponding parts of corresponding triangles are congruent". This means all angles and all sides that corresponds to each other are congruent.

Therefore:

Using the side-angle-side theorem it can be shown that the two triangles are congruent to each other.

Data given:

The series = 512/243, -128/81, 32/27.....

The formula to find the nth term of the geometric sequence:

[tex]a_{n}[/tex] = a[tex]r^{n-1}[/tex]

where [tex]a_{n}[/tex] = nth term of the sequence

a = first term of the sequence

r = common ratio

common ratio(r) = -128/ 81 ÷ 512/ 243

                       = -128/81 × 243/512

                       = -3/4

Now we have to find the 6th term of the series.

A bijection between two sets is constructed below and also proved that it is both one-one and onto.

The phrase "one-to-one function" should not be mistaken with "one-to-one correspondence," which is used to describe bijective functions, in which each element in the codomain is a precise mirror image of a single element in the domain.

Any function that can work with the operations of two algebraic structures is said to be a homomorphism between them. An injective homomorphism is also referred to as a monomorphism for any commonly occurring algebraic structures, particularly vector spaces.

Let t∈T

Then,

t=2k+1, for some k∈Z

Let s=3k

Then,

s∈S and f(s)=2(s/3)+1

=2k+1

=t

Therefore, for every t∈T there exists s∈S such that f(s)=t

Thus, f is onto.

Hence,

f:S  ----> T is a bijective mapping

⇒|S|=|T|

Now, we have to define a mapping f:S ---?T

By f(x)=2(x/3)+1, ∀x∈S

Given,

S={3k|k∈Z} and T={2k+1:k∈Z}

We have to prove:

|S|=|T|

Let x, y∈ S with f(x)=f(y)

Then,

2(x/3)+1=2(y/3)+1

2(x/3)=2(y/3)

(x/3)=(y/3)

x=y
