A fast food restaurant sold 35 burgerswith cheese. If the ratio of burgers soldwith cheese compared to withoutcheese was 7:3, how many burgers didthey sell total?
Answers
Answer:
The total number of burgers sold is: 50
Problem Statement
The question tells us a restaurant sold 35 burgers with cheese and also that the ratio of burgers sold with cheese compared to burgers sold without cheese is 7:3.
We are asked to find the total amount of burgers sold; with and without the cheese.
SOLUTION
The question already told us that the ratio of burgers sold with cheese to those without cheese is 7:3. This means that for every 7 burgers with cheese sold, the restaurant also sold 3 burgers without any cheese.
This further implies that out of 10 burgers sold at a time, the restaurant must have sold 7 cheeseburgers and 3 burgers without cheese.
This means that we can say:
[tex]35\text{ burgers represent }\frac{7}{10}\text{ of burgers sold by the restaurant}[/tex]If this is the case, then we can also say that:
[tex]\frac{3}{10}\text{ of the total burgers sold is without cheese}[/tex]Thus, we can write an equation stating that "35 burgers plus 3/10 of the total burgers (B) must be equal to the total number of burgers (B)"
This is done below:
[tex]\begin{gathered} 35+\frac{3}{10}\times B=B \\ 35+\frac{3B}{10}=B \\ \text{Multiply both sides by 10} \\ 350+3B=10B \\ \text{Subctract 3B from both sides} \\ 350+3B-3B=10B-3B \\ 350=7B \\ \text{Divide both sides by 7} \\ \frac{350}{7}=\frac{7B}{7} \\ 50=B \\ \\ \therefore B=50 \end{gathered}[/tex]Final Answer
Thus, the total number of burgers sold is: 50
What transformations to the linear parent function, f(x) = x, give the functiong(x) = 3x - 1? Select all that apply.A. Horizontally stretch by a factor of 3.B. Shift left 1 unit.nC. Vertically stretch by a factor of 3.UD. Shift down 1 unit.SUBMIT
Answers
We are given a parent function f(x)= x and asked the transformation process that takes it to g(x)=3x-1
PART 1
If g(x) = 3f (x): For any given input, the output g(x) is three times the output of f(x), so the graph is stretched vertically by a factor of 3. If g(x) = f (3x): For any given output, the input of g is one-third the input of f(x), so the graph is shrunk horizontally by a factor of 3.
In this case, we can state that the function was first stretched by 3.
PART 2
To move a function up, you add outside the function: f (x) + b is f (x) moved up b units. Moving the function down works the same way; f (x) – b is f (x) moved down b units.
We can also say that the function was shifted downwards by 1

If carpeting costs R75,50/m and an entrance hall has a length of 468,cm. Determine the cost of carpenting the hallway?
Answers
The cost of carpeting the hallway is Rs. 35,334.
The cost of carpeting is Rs. 7,550 per meter. We have an entrance hall. The length of the entrance hall is 468 cm. We need to find out the total cost of carpeting the hallway.
First of all, we will convert all the quantities to the same units. The length of the entrance hall is 468/100 = 4.68 meters.
The total cost of carpeting the hallway is the product of the length of the hallway and the cost of carpeting per unit length. Let the cost be represented by the variable "C".
C = Rs. 7,550*4.68
C = Rs. 35,334
Hence, the cost of carpeting the hallway is Rs. 35,334.

May I please get help with this. For I have tried many times to figure out the right answers
Answers
Explanation:
Two figures are congruent if they have the same size and shape. In this case, figure B is greater than figure A, so they are not congruent.
However, Figures C and D are congruent and we can map figure C to D by a rotation of 90 degrees counterclockwise about the origin. For example, the point (2, 3) of figure C becomes point (-3, 2), so the rule is
(x, y) ---> (-y, x) which is the rule for a 90 degrees rotation counterclockwise.

We have a line with equation:

[tex]y-y_0=m(x-x_0)[/tex]where (x0,y0) is a point of the line and m is the slope.
As in this case, m = 9/7, then the slope is 9/7.

We also know that (x0,y0) = (-4, 5), that belong to the line.
By inspecting the equation the graph of the line passes through the point (-4, 5).
To find the value of y(3) we replace x with the value 3:

write each measure in radians and express the answer in terms of π4. 315 degrees 5. -450 degrees
Answers
The equivalent measure of (315) degrees in radians will be (7π/4) rads.
As per the question statement, we are provided with an angular measure of 315 in the units of degrees,
And we are required to convert the above mentioned angular measure into it's equivalent unit of radians.
To solve this question, first we need to know about the relation between the two units of angular measure, degrees and radians, which goes as,
[180° = (π) rads]
Now using the unitary method and the above conversion reference point, we get,
[180° = (π) rads]
Or, [1° = (π/180) rads],
And, [315° = {(π/180) * 315} rads]
Or, [315° = {π * (315/180)} rads]
Or, 315° = [π * {(5 * 7 * 3 * 3)/(3 * 3 * 4 * 5)} rads]
Or, [315° = {π * (7/4)} rads]
Or, [315° = (7π/4) rads]

how do you find a vertex in intercept form
Answers
Quadratic functions can be written in vertex form, or
[tex]y=a\mleft(x-h\mright)^2+k[/tex]This is especially useful because the vertex of the function is found at the point (h, k).
We can find this form by completing squares, for instance, let y be:
[tex]y=x^2+bx+c[/tex]we can see that this equation is equal to
[tex]y=x^2+2(\frac{b}{2})x+(\frac{b}{2})^2-(\frac{b}{2})^2+c[/tex]because
[tex]2(\frac{b}{2})=b[/tex]and
[tex](\frac{b}{2})^2-(\frac{b}{2})^2=0[/tex]However, in this form, we can see that the first 3 terms are a perfect square, that is
[tex]x^2+2(\frac{b}{2})x+(\frac{b}{2})^2=(x+\frac{b}{2})^2[/tex]hence,
[tex]\begin{gathered} y=x^2+bx+c \\ y=(x+\frac{b}{2})^2-(\frac{b}{2})^2+c \end{gathered}[/tex]If we define
[tex]\begin{gathered} -(\frac{b}{2})^2+c=k \\ \text{and} \\ h=\frac{b}{2} \end{gathered}[/tex]we have that
