Answer:
Camacho pays in total for the monster truck = $x + $0.13x = $1.13x
Step-by-step explanation:
i.) The price of truck is $x
ii.) Monstor truck tax = 13% of price of truck = [tex]\frac{13}{100}\times $x[/tex] = $0.13x
iii) Camacho pays in total for the monster truck = $x + $0.13x = $1.13x
Options A and D correctly represent how much Camacho pays in total for the truck:
A. (1 + 0.13)x
D. 1.13x
The total amount Camacho pays for the monster truck includes the price of the truck plus the tax, which is 13% of the price of the truck. Therefore, the total amount can be represented by the expression:
[tex]\[ \text{Total amount} = \text{Price of the truck} + \text{Tax amount} \][/tex]
Given that the price of the truck is x dollars and the tax is 13\% of the price, we can represent the tax amount as 0.13x .
So, the total amount Camacho pays is:
[tex]\[ \text{Total amount} = x + 0.13x \][/tex]
[tex]\[ \text{Total amount} = 1.13x \][/tex]
Therefore, options A and D correctly represent how much Camacho pays in total for the truck:
A. (1 + 0.13)x
D. 1.13x
The complete Question is given below:

2453 minus 249 equals
Answer: 2,204
Step-by-step explanation:
Final answer:
To solve 2453 minus 249, align the numbers by place value and subtract each column starting from the rightmost digit, borrowing where necessary. The result of 2453 minus 249 is 2204.
Explanation:
The question is a basic arithmetic problem involving subtraction. The task is to subtract 249 from 2453. We write the numbers in column form, aligning the units, tens, hundreds, and thousands places properly:
2453
- 249
------
We start subtracting from the rightmost digit (units place) and proceed to the left:
Finally, subtract in the thousands place: 2 minus 0 is 2.
After completing the subtraction, we have the result:
2204
Therefore, 2453 minus 249 equals 2204.
9. A relation contains the points ( -5,-10),( -2,-4)(-1,-2),(4,8) and (5,10) . Is this a function? Explain. (2 points)
Answer:
Yes it is a function given by f(x) = 2x
Step-by-step explanation:
Any function can approximated as series or a polynomial. For example,
[tex]e^{x} = 1 + \frac{x}{1!} + \frac{x^{2}}{2!} + \frac{x^{3}}{3!} ...[/tex] (exponential function)
(n! or n factorial is equal to n(n-1)(n-2)...3.2.1 ; 3! = 3.2.1 = 6)
and for the series to converge(the sum does not go to infinity), higher order terms must tend to zero.
General form of a polynomial/series: [tex]f(x) = a + bx +cx^{2} + ...[/tex]
For the given set of points, we can start with the straight line equation:
[tex]f(x) = y = a + bx[/tex] ........(1)
Let us take two points from the given relation: (-5, -10), (-1, -2)
and put the respective x and y values in equation (1), we get two equations, which we can then solve simultaneously to get values of [tex]a[/tex] and [tex]b[/tex]:
[tex]-10=a-5b[/tex] ........(2)
[tex]-2=a-b[/tex] ..........(3)
Now (3) - (2) gives us: [tex]b=2[/tex] and putting the value of [tex]b[/tex] in any of the above equation gives us [tex]a=0[/tex]
Hence, we get the equation, [tex]f(x)=y=2x[/tex]
It can be seen that all the given points satisfies this relation and since we get a unique [tex]y[/tex] for every [tex]x[/tex], we can call this a function.
Final answer:
The provided relation is a function because each x-value is unique and maps to exactly one y-value, fulfilling the criterion that every element of the domain is associated with exactly one element of the range.
Explanation:
The question asks if a relation containing the points (-5,-10), (-2,-4), (-1,-2), (4,8), and (5,10) is a function. To determine if this relation is a function, we need to examine if any x-value (the first number in each pair) repeats with a different y-value (the second number in each pair). Upon inspection, we see that each x-value is unique to a single y-value, which means that each element of the domain maps to a unique value in the range. Therefore, we can conclude that this relation is indeed a function.
In general, a function is defined as a relation in which every element of the domain (set of all first elements) is associated with exactly one element of the range (set of all second elements). This criterion is met in the relation provided as each x-value is unique and paired with only one y-value.

Suppose h(t)= -0.2 + 2t models the height, in feet, of a ball that is kicked into the air where t is given as time in seconds
The maximum height of the ball is found at 64 feet
Explanation:Hello! remember to write complete and clear questions in order to get good and exact answers. I've found a similar question so I have written it in a comment above. We know that h(t) models the height, in feet, of a ball that is kicked into the air where t is given as time in seconds. This equation follows a quadratic function so from math we know that the maximum or minimum of this type of functions is found at the vertex of its graph. So:
[tex]f(x)=ax^2+bx+c \\ \\ \\ Vertex \ (h,k): \\ \\ h=-\frac{b}{2a} \\ \\ k=f(-\frac{b}{2a}) \\ \\ \\ Our \ function \ is: \\ \\ h(t)=-16t^2+64t \\ \\ \\ Comparing: \\ \\ a=-16 \\ \\ b=64 \\ \\ c=0 \\ \\ \\ h=-(\frac{64}{2(-16)})=2 \\ \\ k=-16(2)^2+64(2) \\ \\ k=64[/tex]
Finally, the maximum height of the ball is found at 64 feet

A figure is dilated by a factor of 3. which statement about the mesurements of the image is true
A Dilation factor of 3 means that all dimensions of the figure are three times larger than those of the original figure. This applies to every dimension of the figure including height, width, and depth (if applicable). An example is a rectangle with original measurements 2 cm by 4 cm becoming 6 cm by 12 cm after dilation.
When a figure undergoes a dilation, all its dimensions are altered by the dilation factor.
In this case, the dilation factor is 3, which means that each dimension of the figure is three times larger than before.
It is important to note that this applies to all dimensions: height, width, and depth (if applicable).
For instance, suppose you have a rectangle with a height of 2 cm and width of 4 cm.
If the rectangle is dilated by a factor of 3, the new dimensions would be 6 cm (2 cm * 3) for height and 12 cm (4 cm * 3) for width.

Elle is buying new flooring for her kitchen
and laundry room. She knows that the
area of the kitchen is 132 square feet. The
laundry room is 8 1/3 feet by 6 3/4 feet. What is
the total area of the two rooms?
Answer:
The total area of the two rooms is 188.25 square feet
Step-by-step explanation:
Given:
Area of the kitchen = 132 square feet.
Dimension of the Laundry room = 8 1/3 feet by 6 3/4 feet.
To Find:
The total area of the two rooms = ?
Solution:
Area of the two rooms = Area of the kitchen + Area of the laundry room
Area of the two rooms = 132 + Area of the laundry room
Area of the laundry room =[tex](8 \frac{1}{3}) \times (6 \frac{3}{4})[/tex]
Area of the laundry room =[tex]\frac{25}{3} \times \frac{27}{4}[/tex]
Area of the laundry = [tex]\frac{675}{12}[/tex]
Area of the two rooms = [tex]132 + \frac{675}{12}[/tex]
Area of the two rooms = 132 + 56.25
Area of the two rooms = 188.25 square feet
Final answer:
The total area of Elle's kitchen and laundry room combined is 188.25 square feet. This is found by first calculating the area of the laundry room with given dimensions and then adding it to the area of the kitchen.
Explanation:
The question involves finding the total area of two rooms, given the area of one and the dimensions of the other. The kitchen has an area of 132 square feet. For the laundry room, we need to calculate the area by multiplying its length and width. The dimensions are 8 1/3 feet by 6 3/4 feet. To find the area, convert mixed numbers to improper fractions: 8 1/3 becomes 25/3 feet, and 6 3/4 becomes 27/4 feet. The area is then calculated as (25/3) * (27/4) square feet.
To compute this, multiply the numerators and denominators separately: (25*27) / (3*4) = 675 / 12, which simplifies to 56.25 square feet. Now, add the area of the laundry room to the area of the kitchen to get the total area of both rooms: 132 + 56.25 = 188.25 square feet. Therefore, the total area of the two rooms is 188.25 square feet.

Answer:
[tex]4 \sqrt{6} \times \sqrt{3} = 12 \sqrt{2} [/tex]
Step-by-step explanation:
We want to simplify the radical expression:
[tex]4 \sqrt{6} \times \sqrt{3} [/tex]
We write √6 as √(2*3).
This implies that:
[tex]4 \sqrt{6} \times \sqrt{3} = 4 \sqrt{2 \times 3} \times \sqrt{3} [/tex]
We now split the radical for √(2*3) to get:
[tex]4 \sqrt{6} \times \sqrt{3} = 4 \sqrt{2} \times \sqrt{3} \times \sqrt{3} [/tex]
We obtain a perfect square at the far right.
[tex]4 \sqrt{6} \times \sqrt{3} = 4 \sqrt{2} \times (\sqrt{3} )^{2} [/tex]
This simplifies to
[tex]4 \sqrt{6} \times \sqrt{3} = 4 \sqrt{2} \times 3[/tex]
This gives us:
[tex]4 \sqrt{6} \times \sqrt{3} = 4 \times 3 \sqrt{2} [/tex]
and finally, we have:
[tex]4 \sqrt{6} \times \sqrt{3} = 12 \sqrt{2} [/tex]

She gave 1/3 of cookies for her husband 1/4 of the cookies to her son and 1/6 of a cookies to her neighbor she ate the remaining six cookies how many cookies did she make
She made 15 cookies
Solution:
Let "x" be the number of cookies she made
She gave 1/3 of cookies for her husband
Therefore,
[tex]Husband = \frac{1}{3}x[/tex]
Find the remaining
[tex]Remaining = x - \frac{x}{3} = \frac{3x-x}{3} = \frac{2x}{3}[/tex]
1/4 of the cookies to her son
Therefore,
[tex]son = \frac{1}{4} \times \frac{2x}{3} = \frac{x}{6}[/tex]
Now again find the remaining
[tex]Remaining = \frac{2x}{3} - \frac{x}{6} = \frac{x}{2}[/tex]
1/6 of a cookies to her neighbor
[tex]Neighbor = \frac{1}{6} \times \frac{x}{2} = \frac{x}{12}[/tex]
Now again find the remaining
[tex]Remaining = \frac{x}{2} - \frac{x}{12} = \frac{5x}{12}[/tex]
She ate the remaining six cookies
Therefore,
[tex]\frac{5x}{12} = 6\\\\5x = 72\\\\x = 14.4[/tex]
Thus she made approximately 15 cookies

Expand to write an equivalent expression: -1/4(8x+12y)
Answer:
-2x-3y
Step-by-step explanation:
-1/4(8x+12y)
-8/4x-12/4y
-2x-3y
Final answer:
The expression -1/4(8x+12y) is expanded by distributing -1/4 to both 8x and 12y, resulting in the equivalent expression -2x - 3y.
Explanation:
To expand the expression -1/4(8x+12y), you need to distribute the term outside the parenthesis (-1/4) to each term inside the parenthesis. This process is known as the distributive property of multiplication over addition. Here's the step-by-step process:
Multiply -1/4 by 8x to get -2x.Multiply -1/4 by 12y to get -3y.Combine these two products to get the expanded expression: -2x - 3y.In conclusion, the equivalent expression after expanding -1/4(8x+12y) is -2x - 3y.
