What is a fraction?

If the numerator is bigger, it is referred to as an improper fraction and can also be expressed as a mixed number, which is a whole-number quotient with a proper-fraction remainder.

Any fraction can be expressed in decimal form by dividing it by its denominator. One or more digits may continue to repeat indefinitely or the result may come to a stop at some point.

I honestly do not know???

Answer:

[tex]x = 180 - \frac{y}{2}[/tex]

Step-by-step explanation:

Our goal here is to isolate [tex]x[/tex] on one side of the equals sign

[tex]360 = 2x + y[/tex]

Here we have 2 terms on the right side of the equals sign, [tex]2x[/tex] and [tex]y[/tex]

in order isolate the [tex]x[/tex] term we must subtract [tex]y[/tex]

However, if we subtract [tex]y[/tex] from one side of the equation we must also do the same to the other side to a maintain balanced equation.

[tex]360 = 2x + y[/tex]
[tex]-y[/tex]           [tex]-y[/tex]

[tex]360 - y = 2x[/tex]

Now to remove "2" from [tex]2x[/tex] we must do the opposite of multiplication, which is division.

[tex]\frac{360}{2} - \frac{y}{2} = \frac{2x}{2}[/tex]

simplify.

[tex]180 - \frac{y}{2} = x[/tex]

The Interquartile Range (IQR) formula is a measure of the middle 50% of a data set. The smallest of all the measures of dispersion in statistics is called the Interquartile Range. The difference between the upper and lower quartile is known as the interquartile range.

Formula to find the interquartile range is Interquartile range = Upper Quartile - Lower Quartile =Q2=Q3-Q1

The  order of the given data is 1.56, 1.77, 2.22, 2.35, 2.45, 2.77, 3.26, 4.38, 5.23, 6.02.

557,568 inch³ of refrigerant can be held by the tubing.

Here we have to find how much a refrigerant can hold.

Data given:

outer diameter (d) = 78inch

outer radius(r) = 39 inch

inner diameter (d') = 34 inch

inner radius (r') = 17inch

Height (h) = 12 feet

= 12 × 12

= 144 inch

the formula to find the volume of the cylinder:

volume= пr²h

So here we get

Refrigerant hold = Volume of the outer cylinder - the volume of the inner cylinder

= πr²h - πr'²h

= πh(r² - r'²)

= π ×144 ( 39² - 17²)

= π × 144 ×56 × 22

= 22/7 × 144 × 56 × 22

= 557,568 inch³

Therefore the refrigerant can hold 557,568 inch³.

The angle B for the triangle ABC has a measure of 118° so the correct option is 118°.

The angle B and its exterior angle lie on a straight line, thus their sum is equal to 180°

From the question, we are given that;

m∠B = (12x − 26)° and the exterior angle = (7x − 22)°

so;

12x - 26 + 7x - 22 = 180° {collect like terms}

19x - 48 = 180°

19x = 180° + 48° {add 48° to both sides}

19x = 228°

x = 228°/19 {divide through by 19}

x = 12

Therefore, by putting the value 12 for x in m∠B = (12x − 26) we get the angle B as;

B = 12(12) - 26

B = 144 - 26

B = 118°

In conclusion, the triangle ABC, with m∠B = (12x − 26)° and the measure of the exterior angle to ∠B is (7x − 22) have the angle B equal to 118°.

Permutation and combination: The process of ordering objects or numbers is known as permutation. Combinations are a method of choosing items or numbers from a collection or group of items so that the order of the items is irrelevant.

Combinations are used to group objects or to determine how many subgroups can be formed from the given collection of objects. Additionally, we use permutations to determine the number of potential combinations of unrelated objects.

For example, if we want to select 2 players from 6. This will be:

= 6! / 2! (6 - 2)!

= 15 ways

In the given question use the combination. We can write as:

[tex]52C_{4}[/tex] = 52!/4! (52-4)!

This expression could be written in the form

[tex]52C_{4}[/tex] = 52!/4! (52-4)!

[tex]52C_{4}[/tex] = 52!/(4! (48)!)

[tex]52C_{4}[/tex] = 52 x 51 x 50 x 49 x 48!/(4 x 3 x 2 x 48!)

As, 48! cancel out. We get,

[tex]52C_{4}[/tex] = 52 x 51 x 50 x 49/24

The best approximation for the area of the circle is 201.0in³

The size of a region on a planar or curved surface is expressed mathematically as area. The term "surface area" refers to the area of an open surface or the perimeter of a three-dimensional object, whereas "plane area" refers to the area of a shape or planar lamina. Area can be thought of as the amount of a certain thickness of material required to construct a model of the shape. For the areas of basic forms like circles, triangles, and rectangles, there are a number of well-known formulas. Any polygon can be divided into triangles to get its area using these formulas. Calculus is commonly needed to calculate the area of forms having curved boundaries. Calculus' historical growth was in large part driven by the issue of figuring out the area of plane figures.

It is possible to calculate a shape's area.

As we already know that,

The area of a circle=πr²

Here, r=8in

π=3.14

Then,

A=(3.14)(8²)

A=201.0in²

Therefore, Area=201.0in²

The slope of the line that passes through (4,1) and (2,5) is -2.The slope of a line can be expressed in many ways, including as a fraction, decimal, or even in terms of the angle of inclination.

The slope or gradient of a line in mathematics is a numerical representation of the steepness and direction of the line.The slope of a line is calculated by finding the difference in the y-values (rise) divided by the difference in the x-values (run).

In this case, the rise is 5 - 1 = 4 and the run is 2 - 4 = -2.

Therefore, the slope of the line is 4/-2 = -2.

In the case of a horizontal line, the slope is 0, and in the case of a vertical line, the slope is undefined. The slope is a useful tool in mathematics as it can be used to determine the equation of a line, the rate of change on a graph, or the amount of change for every unit of time. It can also be used to determine the area between two points on a graph. Slope is an essential concept in mathematics and can be used to solve many types of problems.

The surface area of the plane is π√14 sq. units.

It is given in the question that the equation of the plane = x+2y+3z=1 and that of the cylinder

= x² + y² = 5                                                                  [1]      

Let J be the projection on the plane x+2y+3z=1

We know that the surface area of an equation is

∫∫j  √{1+(∂z/∂x)² + (∂z/∂y)²} dA

We know that the plane is inside the cylinder.

By using the coordinates of the cylinder we can get

x = r cosθ and y = rsinθ

Squaring both sides gives us

x² = r²cos²θ

y² = r²sin²θ

Therefore we get,

x² + y² =  r²cos²θ + r²sin²θ

= r²(cos²θ + sin²θ)

We know that cos²θ + sin²θ = 1. Hence,

=  r²                                                                         [2]

From equations [1] and equation [2] we get

r² =  5

or, r = √5

Hence,

J = {(r,θ)/ 0 ≤ r ≤ √5, 0 ≤ θ ≤ 2π}

Therefore,

x +2y + 3z =1

or, z = 1/3(1 - x - 2y)

Partially differentiating z with respect to x and with respect to y gives us

∂z/∂x = -1/3

and,

∂z/∂y = -2/3

Therefore,

We already know that Surface Area = ∫∫j √{1+(∂z/∂x)² + (∂z/∂y)²} dA

= ∫∫j √{1+ (-⅓) ² + (-⅔) ²} dA

= ∫∫j √(9+1+4)/√9 dA

= √14 /3∫∫j dA

=√14/2 [2π - 0]
