ANSWER

EXPLANATION

We have that Sarah got a $60 gift card to use in Walmart.

This means that everything she can buy cannot be worth more than $60 (i.e. less than or equal to $60).

She buys orange juice for $4.50 and she wants to buy shirts (which cost $2.29 each)

Let n be the number of shirts Sarah wants to buy.

This means that the cost of n shirts is $2.29n.

Recall that she can only spend less than or equal to $60. This means that the sum of the cost of the orange juice and n shirts is less than or equal to $60.

That is:

That is the inequality that represents the situation.

Congruent shapes are produced by combining the three different transformations—rotations, reflections, and translations. Actually, by combining one or more of these three transformations, any pair of congruent shapes can be matched to one another.

A point, line, or geometric figure can be transformed in four different ways, each of which alters the shape and/or placement of the object. While Image refers to the position and ultimate shape of the object, Pre-Image refers to the shape of the thing as it was before alteration.

Given Data

We now understand that the size and shape of the figures are preserved during stiff transformations (reflections, translations, and rotations). The pre-image and the actual image concur all the time.

The following Matt's transformational skills:

Reflection

Since the reflection maintains its original shape, The line of reflection remains the same distance away from comparable points from the pre-image to the image.

As a Congruence Transformation, rotations

Rotating a figure causes it to twist. Even though the figure is the same size and shape as before, it appears to have toppled over. A clock is a fantastic example of how the earth actually rotates. Every hour or every day, the clock's connecting arms revolve around their axis. A rotation's degree determines what it is, and common rotations include 90, 180, and 270 degrees. Before going back to its original position, the figure rotates a full 360 degrees. the direction of a rotation, whether it is counterclockwise or clockwise. It is possible to determine the degree, amount, and the revolution's direction.

Transformation based on translational congruence

When an object or shape is transported from one location to another without changing its size, shape, or orientation, the movement is referred to as a translation. During a translation, also known as a slide, every point on an object or shape is moved by the same amount and in the same direction.

Step-by-step explanation:

1) Whenever we have problems that deal with the real distance and distance on the map, we can write out the following formula:

So, let's call the Real distance "R". Note that in this question, 1 centimeter represents 20 kilometers

2) So, in order to plug that as the scale we need to convert kilometers to centimeters:

3) Finally, we can plug that into the formula and cross multiply the ratios this way:

Converting it back to kilometers we can write:

The solution to the inequality is m ≤ -14/11 which is the correct answer would be option (C).

A graph can be defined as a pictorial representation or a diagram that represents data or values.

If it is "> or," the shaded arrow is drawn to the right of the inequality graph; if it is "or," it is drawn to the left.

Given the inequality, -1/2m ≥ 7/11,

Which represents the solution to one-half m is greater than or equal to negative seven elevenths

Solve for m:

⇒ -1/2m(-2) ≥ 7/11(-2)

m ≤ -14/11 [Because we are multiplying both sides by a negative value, the sign shifts]

The solution to the inequality is m ≤ -14/11 which the graph is attached below for m ≤ -14/11.

Answer: x > -3 or x < -5

Step-by-step explanation:

The function is positive when y > 0.

So if we make this function into an inequality, we can solve for the values of x.

0 < |x + 4| -1

1 < | x + 4 |

Absolute values make the answer always positive despite the sign so now we have to solve for x when x + 4 > 1 and when x + 4 > -1.

x = 1 - 4 = -3

x = -1 -4 = -5

So for the function to be positive,

x > -3 or x < -5

The sum of the two numbers 1,235,721 and 9,576,345,123 is 9,577,580,844 after applying the arithmetic operation.

It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that is +, -, ×, and ÷.

It is given that:

= 1,235,721 + 9,576,345,123

The above number expression is representing the sum of two big numbers.

After applying the arithmetic operation on the number expression:

1,235,721 + 9,576,345,123 = 9,577,580,844

Thus, the sum of the two numbers 1,235,721 and 9,576,345,123 is 9,577,580,844 after applying the arithmetic operation.

D. In the ordered pair (9,7), 7 is the x-coordinate

Explanation:

The ordered pairs have the form (x, y) where the first number is the x-coordinate and the second number is the y-coordinate. So, in the ordered pair (9, 7), 7 is the y-coordinate. This makes the last statement false and the answer is

D. In the ordered pair (9,7), 7 is the x-coordinate.

Given:

x > 3 and x < 5

The inequality compound is:

From the given equation 13x + 5y - 2 = 3, we can tell that;

Variables are; x and y

Coefficients are; 13 and 5

Constants are; -2 and 3

We are given the equation;

13x + 5y - 2 = 3

A variable is a term that is subject to change and is not fixed. Thus, in our expression, the variables are x and y.

Now, the constants are terms that a single without a variable attached to them. Thus, in our expression, the constants are -2 and 3

The coefficients are basically the numbers that are attached to the variables. Thus, the coefficient of x is 13 and the coefficient of y is 5.

A rotation of 270 degrees counterclockwise is the same as a rotation 90 degrees clockwise.

This rotation will make a point from the first quadrant go to the fourth, from the second to the first, from third to second and from fourth to third.

If the point goes from the first quadrant to the fourth, we change the signal of the x-coordinate.

If the point goes from the second quadrant to the first, we change the signal of the y-coordinate.

If the point goes from the third quadrant to the second, we change the signal of the x-coordinate.

If the point goes from the fourth quadrant to the third, we change the signal of the y-coordinate.

Also, in all those rotations, we need to switch the x and y coordinates between themselves.

Let [tex]r[/tex] equal the number of rides

System of Equations

[tex]2.50g+4r=52.50[/tex]

One game costs $2.50, so [tex]g[/tex] games cost [tex]2.50g[/tex]. One ride costs $4.00, so [tex]r[/tex] rides cost [tex]4r[/tex]. The total [tex]2.50g+4r[/tex] equals $52.50: [tex]2.50g+4r=52.50[/tex]

What is function?

A function from A to B is a rule that maps to each element of A a unique element of B.

A is called the domain of the function and B is called the co domain of the function.

We can do addition, subtraction, multiplication, division and composition on functions.

Let f and g be two functions

f[tex]o[/tex]g(x) = f(g(x)) and g[tex]o[/tex]f(x) = g(f(x))

This is known as composition of function.

The total area of all exposed surfaces of a geometric solid is called surface area .

The area is the entire amount of space filled by flat or two-dimensional objects. In other words, the number of square units that cover the surface of a closed figure is used to represent its area.

It is quantified in square inches, or square units. The area only has length and width since 2-dimensional shapes can be measured using them.

The area is a two-dimensional measurement of the size of a flat surface, whereas surface area is a measurement of a solid shape's exposed surface (three-dimensional).

The main distinction between area and surface area is this. However, both amounts are expressed in square units, which is the same for both. Learn the distinction between area and volume as well.
