Answer: In 6 years the sum of Manas' age and his sister's age will be 48 years.

Step-by-step explanation:

We know that value of a dozen is 12 and the score is 20.

Hence,

Uncle Mike's age = 12+20 = 32 years

Since Manas' sister is 8 years younger than Mike,

Her age = 32 - 8 = 24 years

We know that Manas is half her age. Therefore,

Manas' age  = 24 ÷ 2 = 12 years

After x years the sum of Manas' age and his sister's age will be 48 years.

Manas' future age = (12 + x) years

His sister's future age = (24 + x) years

The Sum of their ages is 48 years. Hence,

(24 + x) + (12 + x) = 48

36 + 2x = 48

2x =  48 - 36

2x = 12

x = 12 ÷ 2

x = 6

Therefore, in 6 Years sum of their ages is 48 years.

The length of the hypotenuse is 6.71

The Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this rule, the areas of the squares on the other two sides add up to the area of the square whose side is the hypotenuse, or the side across from the right angle. This theorem can be expressed as the Pythagorean equation, which is an equation relating the lengths of the sides a, b, and the hypotenuse c:

[tex]{\displaystyle a^{2}+b^{2}=c^{2},}[/tex]

Given ,

Pythagorean therum

a^2 + b^2 = c^2....a and b are ur legs and c is the hypotenuse

Representative fraction is a form of scale that can be used to change the size of an object to form an image. The required length is 32 inches.

A scale is a fraction of numbers that can be used to either increase or decrease the size of a given object. It is majorly referred to as representative fraction in scale drawing.

Representative fraction = [tex]\frac{length on drawing}{original length}[/tex]

In the given question, we have;

12 inches = 1 feet

x inches = 30 feet

So that:

x = 30 x 12 inches

  = 360 inches

representative fraction = [tex]\frac{2 inches}{360 inches}[/tex]

                             = 5.56 x [tex]10^{-3}[/tex]

Based on the information provided, the correct statement is: The smallest residual is 14, and the largest residual is 51. The largest residual corresponds to an outlier in the data.

A residual is the difference between the actual value of the dependent variable (in this case, the number of customers) and the predicted value of the dependent variable based on the model (in this case, the line of fit). In other words, it is the error or deviation between the observed data and the model.

In this case, the smallest residual is 14, and the largest residual is 51. This means that the model is most accurate when predicting the number of customers on days with temperatures close to 82°F and least accurate when predicting the number of customers on days with temperatures close to 91°F. The large residual of 51 corresponds to an outlier in the data, which means that the model is not a good fit for this data point and may not accurately predict the number of customers on days with temperatures close to 91°F.

Option A is correct because it correctly describes the range and magnitude of the residuals and identifies the largest residual as corresponding to an outlier in the data. Options B, C, and D are all incorrect because they either do not correctly describe the range or magnitude of the residuals or do not correctly identify the largest residual as corresponding to an outlier in the data.

The equation of the line in slope-intercept form is y = -2x+8

The equation of a line is an algebraic form of representing the set of points, which together form a line in a coordinate system

The slope-intercept form of  the equation of a line is y = mx+b,

where m is the slope and b is the y-intercept

Given the table, pick any two points in order to find the slope:

point 1: x₁ = 0, y₁ = 8

point 1: x₂ = -2, y₂ = 12

slope (m) =  (y₂-y₁) / (x₂-x₁)

slope (m) = (12-8)/(-2-0) = 4/(-2) = -2

Using y = mx+b and x₁ = 0, y₁ = 8:

8 = -2(0) + b

b = 8

y = -2x+8

Thus, the equation of the line is y = -2x+8

The system of equation is inconsistent as these three equations does not give any solution.

In comparison to equations with two variables, a three-variable linear equation requires a little more work to solve. The extra variable is the cause of this complexity.

Even if there are various ways to solve this kind of equation, the elimination technique is still the simplest.

To solve three variable linear equations using the elimination approach, follow these steps:

1. Avoid using fractions and decimals and write all the equations in standard form.

2. Pick an appropriate variable to remove.

3. Remove the chosen variable from any two of the three equations.

4. Choose another set of the two equations, and then take the same chosen variable out.

5. For the two variables they each include, solve the two equations from stages three and four.

6. Replace the answer in fifth step.

7. Reverify by putting them again in the equation.

So according to these given Equations we have to find the value of x, y and z respectively,

-2x + 15y + z = 44

The measure of the diagonal brace of the rectangular painting is 69.5 inches.

A diagonal is a line segment that joins one corner (vertex) of a polygon to another but is not an edge (side). In other words, it joins any two non-adjacent vertices of a polygon. So, we form a diagonal in a polygon when we directly join any two vertices which are not joined by any side.

The diagonal of the brace and the length of one side and width of one side form a right-angled triangle and by Pythagoras we have

diagonal^2 = length(L)^2 + width(W)^2

diagonal^2 = 60^2 + 35^2

diagonal^2 = 3600 + 1225

diagonal^2 = 4825

The angles,  x = 11 and y = 3,if l ll m,

When two rays are linked at their ends, they create an angle in geometry. The sides or arms of the angle are what are known as these rays.

When two lines meet at a point, an angle is created.

An "angle" is the measurement of the "opening" between these two rays. It is symbolized by the character. The circularity or rotation of an angle is often measured in degrees and radians.

Angles are a common occurrence in daily life.

Angles are used by engineers and architects to create highways, structures, and sports venues.

According to our question-

A transversal intersects the parallel lines marked by the letters "l" and "m.

The two suplementary angles have the radii (13x - 19°) and (17y + 5)°, respectively.

Thus, (13x - 19)° plus (17y + 5)° equals 180°.

13x + 17y = 180 + 14

13x + 17y = 194 ————(1) (1)

The comparable angles are (9x + 25) and (13x - 19).

Consequently, (9x + 25) = (13x - 19)

9x - 13x = -19 - 25

-4x = -44

x = 11

By changing equation's value for 'x' (1),

13x + 17y = 194

13(11) + 17y = 194

17y = 194 - 143

17y = 51

y = 3

As a result, the solution will be x = 11 and y = 3.

The height of the right triangle if the area of the triangle is 150 square units = 30 units

In this question, we have been given a right triangle's height is 3 times the length of its base.

We need to find the height of the right triangle if the area of the triangle is 150 square units.

Let h be the height and b is the base of the right triangle.

A right triangle's height is 3 times the length of its base.

So we get an equation,

h = 3b              ............(1)

Using the formula of area of right triangle,

A = 1/2 * b * h

150 = 1/2 * b * 3b                  .........(from equation (1))

300 = 3b^2

b^2 = 100

b = 10

Subatitute above value of b in equation (1),

h = 3 * 10

h = 30 units

Therefore, the height of right triangle is 30 units

Algebraic expressions called polynomials include constants and indeterminates.

Polynomials can be thought of as a type of mathematics. Nearly all branches of mathematics employ them to express numbers, and calculus is one of those branches where they play a crucial role.

A specific kind of expression is a polynomial. A mathematical statement without the equals symbol (=) is called an expression.

An algebraic expression known as a polynomial requires that all of its exponents be whole numbers.

Any polynomial must have variable exponents that are non-negative integers.

Although a polynomial contains variables and constants, we are unable to divide a polynomial by a variable.

According to our question-

-3x3 + 2x2 + 11x - 20 + (10/(-x-7)) = 3x4 + 19x3 - 25x2 - 57x + 150

In order to perform synthetic division, we must first remove the minus sign from the divisor and write out

-7 | -3 -19 25 57 -150

| 21 -14 -77 140

-3 2 11 -20 -10

obtain that

3x4 + 19x3 - 25x2 - 57x + 150 / (-x-7) is equivalent to 3x4 - 19x3 - 25x2 - 57x + 150 / (x+7) is equivalent to 3x3 + 2x2 + 11x - 20 + (10/(-x-7)).

What does volume mean in plain terms?

The capacity of a solid shape is determined using volume, a three-dimensional quantity.

                     It implies that a closed figure's volume determines how much three-dimensional space it can fill.

The volume of a cylinder is given by

   v = πr²h

The total volume of the two hemispheres is given by

   v' = 2× 2/3 πr³

    v' = 4/3 πr³

Now, the total volume of the solid is given by:

  [tex]V_{T}[/tex] = πr²h + 4/3 πr³

  Now, substitute the value of the total volume in the above expression and then solve for h.

       12 = πr²h + 4/3 πr³

        h = 12/πr² - 4r/3

Now, the surface area of the curved surface is given by:

        A = πrh

Now, the surface area of the two hemispheres is given by

      A' = 2 × (2πr² )

      A' = 4πr²

Now, the total area is given by

    [tex]A_{T}[/tex] = 2πr ( 12/πr² - 4r/3) + 4πr²

 Simplify the above expression.

  [tex]A_{T} =[/tex]  24/r + 4πr²/3

Now, differentiate the total area with respect to 'r'.

      [tex]\frac{dA_{T} }{dr}[/tex] = -24/r² + 8πr/3

Now, equate the above expression to zero.

     0 = -24/r² + 8πr/3
