For the sum of ages of Adam, Barry, and Charlie is 53 , Barry is 14 years old.

Number of brothers are three.

Adam, Barry and Charlie.

Let us consider 'x' years be the age of Barry.

Adam age is equal to (2x) years.

And Charlie age is equal to ( x - 3 )years.

Sum of their ages = 53

Substitute the value of Adam, Barry and Charlie age we get,

⇒ x + 2x + x - 3 = 53

⇒ 4x = 53 + 3

⇒ 4x = 56

⇒ x = 56 / 4

⇒ x = 14 years

Barry is  14 years old.

Adam = 2(14 )

          = 28 years

Charlie = 14 - 3

            = 11 years

Therefore, as per the information about the ages of Adam, Barry and Charlie , the Barry is 14 years old.

The money that a organisation earns in return for their labour or products is referred to as income.She make from each source last year $6000.

The money that a person or organisation earns in return for their labour or products is referred to as income.

Salary, rent, capital gains, company revenue, and income from other sources are a few typical sources of income. Understanding how each type of income is taxed is not always simple, and you may require an income tax calculator to do so.

Let t=teaching income, p=painting income, and b=book sales income.

t=p+6000 b=(t+p)/7 b+t+p=48000 (t+p)/7 +p+6000+p=48000 substitute (2p+6000)/7 + p+6000 + p = 48000 (2p+6000) + 7(p+6000) + 7p = 7*48000 multiply each side by 7 to eliminate the fraction.

substitution (2p+6000)/7 + p+6000 + p = 48000 (2p+6000) + 7(p+6000) + 7p = 7*48000

2p+6000+7p+42000+7p=336000

16p+48000=336000

16p=336000-48000

16p=288000 \s16p/16=288000/16

p=$18,000.

t=18000+6000

t=$24,000.

b=(24000+18000)/7

The powers that have same value as 1^8 are 1^n, n^0 where n=real number.

What are real numbers?

Real numbers are simply the combination of rational and irrational numbers, in the number system. In general, all the arithmetic operations can be performed on these numbers and they can be represented in the number line, also. At the same time, the imaginary numbers are the un-real numbers, which cannot be expressed in the number line and are commonly used to represent a complex number. Some of the examples of real numbers are 23, -12, 6.99, 5/2, π, and so on.

Now,

As we know anything raised to the power of 1 is always one and 0 raised to the power of anything is also one.

Hence, the powers that have same value as 1^8 are 1^n, n^0 where n=real number.

Answer:

a) The hypotenuse side is BC.

b) Using the Pythagorean Theorem, we can determine the missing side: AB = √(AC² - BC²) = √(6² - 4²) = √(36 - 16) = √20 = 4.47.

c) The perimeter of the triangle is AC + BC + AB = 6 + 4 + 4.47 = 14.47.

d) The area of the triangle is ½ × AC × AB = ½ × 6 × 4.47 = 13.7.

Step-by-step explanation:

The Pythagorean Theorem states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the hypotenuse. So, for the triangle given, we can use this theorem to calculate the length of side AB, which is the missing side. Then, we can calculate the perimeter of the triangle by adding up all three sides and the area of the triangle by using the formula ½ × AC × AB.

The length of TU in a trapezoid RSUT is  34 units.

To find the length of TU, we can use the midpoint formula. The midpoint formula states that for a line segment with endpoints (x1, y1) and (x2, y2), the midpoint is ((x1 + x2)/2, (y1 + y2)/2).

In this case, we know that X is the midpoint of line segment RS and V is the midpoint of line segment SU. So we can set up the following equation:

(RS/2) + (SU/2) = 44

Where (RS/2) = (30/2) = 15 and (SU/2) = TU/2

So we can substitute this into the equation and get:

15 + (TU/2) = 44

To find TU, we can solve this equation by multiplying both sides by 2:

TU = 2(44) - 2(15) = 64 - 30 = 34

So the length of TU is 34 units.

In a case whereby concrete beam is to rest on two concrete pillars. The beam is a cuboid with sides of length 0.5m, 3m and 0.4m with diameter 0.4m and height 2m. the total volume of concrete needed to make the beam and the pillars is 1.103m^3

The concept here is total volume , then we can calculate this for concrete needed to make the beam and the pillars  as:

Vtd = V1 + V2

= V1= lwh

where length  l = 0.5m,

width w=  3m

height h=  0.4m.

V1 + V2 = (0.5m* 3m * 0.4m) + 2(π/4 d^2. h)

where h =height 2m

The relationship between x and y can be described based on the value of the sample correlation coefficient.

Sample covariance measures the degree to which two variables are linearly related and the direction of their linear relationship. The formula for sample covariance is:

[tex]Cov(x,y) = (1/(n-1)) * \Sigma(x-\bar x)(y- \bar y)[/tex] where,

The sample correlation coefficient, also known as Pearson's correlation coefficient, measures the degree to which two variables are linearly related and the direction of their linear relationship. It is a normalized version of the sample covariance, with a value between -1 and 1. The formula for the sample correlation coefficient is:

r = Cov(x,y) / (s1 * s2) where,  

To calculate the sample covariance and sample correlation coefficient, we need to have a sample of data containing the variables x and y. Once we have the data, we can calculate the sample means, and sample standard deviations, and then use the formulas above to calculate the sample covariance and sample correlation coefficient.

The missing angle measures in triangle ABC are 35.5° and 54.5°.

We know that,

In the right triangle ABC

∠A +∠B =90°   ( by complementary angles)

We find the measure of angle B.

we know that

[tex]tanB = \frac{opposite side angle B}{adjacent side angle B}[/tex]

According to the question,

Opposite side angle B= 7 in

Adjacent side angle B = 5in

So, [tex]tanB = \frac{7}{5}[/tex]

      [tex]B = arc tan(\frac{7}{5})[/tex]

      B = 54.5°

Then, we find the measure of angle A

A + B = 90°

 A = 90°-B

A = 90° -  54.5° ( using subtraction)

A = 35.5°

The height of the given triangle is 4cm.

Let the base of the triangle be x cm.

It is given that the height of the triangle is 8cm shorter than the base.

∴ Height of the triangle = ( x-8 ) cm

Now,

       Formula for the area of a triangle = 1/2 × Base × Height  sq units.

       It is given that the area of the triangle is 24 cm^2.

       Area= 1/2* x(x-8) cm^2

     ⇒ 1/2 × x(x-8) = 24

    ⇒  x(x-8) = 48

    ⇒ [tex]x^{2}[/tex] - 8x -48=0

    ⇒ [tex]x^{2}[/tex] - 12x + 4x -48 = 0

    ⇒ x(x -12) +4(x-12) = 0

    ⇒ ( x-12 )( x + 4) =0

    ⇒ x= 12 , -4

Since, x is a length so it can not be negative value.

∴ x = 12 cm

Now, height = x-8= 4 cm

Therefore, The height of the given triangle is 4cm.

To write the equation of a line that is perpendicular to y = 2x - 5, we need to find the slope of the new line.

As we know, the slope of a line perpendicular to y = 2x - 5 is the negative reciprocal of the slope of y = 2x - 5, which is -1/(2) = -1/2.

To find the equation of the line in slope-intercept form (y = mx + b), we can use the point (2, -5) and the slope of -1/2.

We know that the point (2, -5) belongs to the line, so we can substitute these values into the equation:

y = -1/2x + b

-5 = -1/2(2) + b

-5 = -1 + b

b = -4

So, the equation of the line in slope-intercept form is:

y = -1/2x -4

This is the equation of a line that is perpendicular to y = 2x - 5 and passes through the point (2, -5)
