According to the given statement the  fraction of pizza did Billy eat for a snack = 1/12

A fraction is a subset of a bigger whole. In arithmetic, the number is expressed as a quotient, which represents the numerator divided by that of the denominator. In a simple fraction, both are integers. A complex fraction has a fraction in both the numerator and the denominator.

A fraction, often known as a fractional number, is used to represent a portion of a whole. Fractions are made up of two numbers: a numerator (the number above the line) as well as a denominator (which is below the line). The denominator is the number of equal pieces that anything is divided into.

According to the given data, It is Transformation of rotation by 180°.

Transformations are changes that appear in the shapes present on a coordinate plane by rotation, reflection or translation. A function, f, that maps to itself is called the transformation, that is if f = X → X'. This transformation can be any one of the translation, rotation, reflection, and dilation or the combination of operations like translation, rotation, reflection, and dilation. The translation is moving a function in a specific direction, rotation is spinning the function about a point, reflection is the mirror image of the function, and dilation is the scaling of a function.

The transformation that rotates each point in the shape at a certain number of degrees around that point is called transformation of rotation. The shape rotates counter-clockwise when the degrees value is positive and it rotates clockwise when the degrees value is negative. The general rules for transformation of rotation about the origin are given below,

To rotate 90º: (x,y) → (-y, x)

To rotate 180º (x,y) → (-x,-y)

To rotate 270º (x,y) → (y, -x)

given data: preimage → image

                   R( -4, 3 ) changes to R'( 4,-3 )

                   S( -1, 3 ) changes to S'( 1, -3 )

                   T( -4, 1 ) changes to T'( 4,-1 )

As we can notice similar trend in the data given in the question like 180° rotation, Thus we can conclude that the coordinate rule and transformation is Transformation of rotation.

The net change between the given values of the variable is;  - 3x² - 6xh - 3h² + 23

We are given the function;

f(x) = 5 - 3x²

x = 3

x = 3 + h

The net change is just looking for the difference between f(3) and f(3 + h). Thus, we will evaluate the function at x = 3 and x = 3 + h and then calculate f(3 + h) - f(3).

f(3 + h) = 5 - 3(x + h)²

= 5 - 3x² - 6xh - 3h²

f(3) = 5 - 3(3)²

f(3) = 5 - 27

f(3) = -18

Net Change = f(3 + h) - f(3)

The cost for a day at the amusement park as a function of the number of ride tickets purchased is y = 12 + 2.75x

Linear equations are equations that have constant average rates of change. Note that the constant average rates of change can also be regarded as the slope or the gradient

The given parameters are:

Admission rate to the amusement park = $12

Cost of each ticket = $2.75

Let the number of tickets be x, and the total cost be y

So, the function can be represented as

y = Admission rate to the amusement park + Cost of each ticket * x

This gives

y = 12 + 2.75 * x

Evaluate the product

y = 12 + 2.75x

Hence, the cost for a day at the amusement park as a function of the number of ride tickets purchased is y = 12 + 2.75x

_______________________________

It is given that Elsa used the multiplication table below to write ratios that are equivalent to 12-4 and one number is missing from the given ratios, we need to find that missing number.

Now, first of all let us understand what are equivalent ratios;

When we compare two ratios, they are said to be equivalent. To determine whether two or more ratios are equivalent, they can be compared to one another. For instance, the ratios 1:2 and 2:4 are equivalent.

Furthermore, in the given question we are given one ratio that is;

=> 12:4 which can also be written as,

=> 3:1

Now, let us assume that the other ratio is x:y than;

=> x:y

So, let us compare both the ratios as they are equivalent ratios;

=> x:y = 3:1

To calculate the other ratio, we need to divide it by 12 so that we get the equivalent ratio;

=> x/12 = 12/4

=> x/12 = 3

=> x = 12 × 3

=> x = 36

So,

=> 36/12 = 12/4

=> 3/1 = 3/1

Therefore, the missing number is 36 so that the equivalent ratios become 3:1, so that the option D is correct.

The standard form of the given linear equation y = (-2/3)x + 5 is 2x + 3y = 15.

The standard form of a linear expression is expressed as;

Ax + By = C

Where A and B are the coefficient of x and y respectively and C is the constant term.

Given the equation in the question;

y = (-2/3)x + 5

Multiply both sides by 3

y = (-2/3)x + 5

3(y) = 3((-2/3)x + 5 )

Apply distributive property

3(y) = 3((-2/3)x + 5 )

3y = 3(-2/3)x + 3( 5 )

3y = -6/3x + 15

3y = -2x + 15

Now, move all terms containing variables to the left side of the equation

3y = -2x + 15
Add 2x to both sides

3y + 2x = -2x + 2x + 15

3y + 2x = 15

Reorder 3y and x

2x + 3y = 15

Therefore, the standard form of the given linear equation y = (-2/3)x + 5 is 2x + 3y = 15.

It is common to discuss numbers when writing academic or professional documents.

It may be appropriate to spell out a number with a decimal if you're sharing statistics or explaining a mathematical concept.

Learning how to properly write decimals can help you create documents that meet expectations.

The proper way to convert worded forms into decimals:

Let's do an example.

Twenty-three and six-tenths,

We are given four numbers.

It is easy to see that Twenty-three equals 23.

But what about the decimal?

Decimals in worded form are always after "and," and they always have "th(s)" at the end, rather than what would appear there in regular numbered word form.

So, given "six-tenths," it is pretty simple.

Six-tenths=0.6

The reason for this is that the word "tenths," won't make it 0.16, because, in decimals, we always skip what would be oneths. The reason for this is; is that this only makes sense if there were "oneths," and dividing a "whole" into "oneths" resulted in the "whole"... So that spot was already taken.

Step-by-step explanation:

The area under a curve on an interval [a, b] is the integral of the function computed in this interval :  [tex]A=\int _a^b|f\left(x\right)|dx[/tex]

(1) For [tex]f\left(x\right)=3\sqrt{x}[/tex] with [tex]a=1,\:b=4[/tex]

area [tex]=\int _1^4\left3\sqrt{x}\;dx[/tex] = [tex]3\cdot \int _1^4\sqrt{x}dx[/tex] =

[tex]\int \sqrt{x}[/tex] = [tex]\frac{2}{3}x^{\frac{3}{2}}[/tex]

[tex]3\cdot\frac{2}{3}x^{\frac{3}{2}}[/tex] = [tex]2x^{\frac{3}{2}}[/tex]

At [tex]x = 4,[/tex] we get [tex]2\cdot4^{\frac{3}{2}}[/tex] = [tex]2\cdot8 = 16[/tex]

At [tex]x = 1,[/tex] we get [tex]2\cdot1^{\frac{3}{2}}[/tex] = [tex]2.1 = 2[/tex]

So area under the curve for [tex]f(x) = \:3\sqrt{x}[/tex] in the interval [tex][1, 4] = 14[/tex]

(2) [tex]f\left(x\right)=x-\frac{2}{3}\\[/tex]

[tex]\int \:x-\frac{2}{3}dx[/tex] = [tex]\int \:xdx-\int \frac{2}{3}dx[/tex]  [tex]=\frac{x^2}{2}-\frac{2}{3}x[/tex]

[tex]\left[\frac{x^2}{2}\right]^{27}_1 = \frac{27^2}{2} - \frac{1}{2} = \frac{729}{2}-\frac{1}{2} = \frac{728}{2} = 364[/tex]
