Answer:

4.95 for 15 slices of cheese

Step-by-step explanation:

you do 8.91/27 and you get 0.33 the multiply by 15 and you get 4.95

Answer:

$4.95

Step-by-step explanation:

Step 1: Find the unit rate (price per slice)

$8.91 / 27 slices = $0.33 per slice

Step 2: Find the price for 15 slices

$0.33 per slice * 15 slices = $4.95

Therefore, the price of 15 slices at the same rate would cost $4.95

The total amount an aerobics teacher makes for teaching x number of students can be represented by the function T(x)=4x. If T(25)=100, then teaching ____ students makes the teacher ____$

Answers

Answer:

Teaching 25 students makes the teacher 100 dollars.

======================================================

Explanation:

The notation T(25) means "The value of T(x) when x = 25".

The instructions state that x represents the number of students. So x = 25 means the teacher has 25 students.

Writing T(25) = 100 means the teacher earns $100 from teaching 25 students.

We could also write T(x) = 100 when x = 25. Though it's more compact to say T(25) = 100.

--------------------------

Note that,

T(x) = 4x

T(25) = 4*25 ... replace x with 25

T(25) = 100

As you can probably see by now, each student pays $4 which is what leads to the $100 total.

twelve cubes stacked in this figure part a: what is its surface area

Answers

Answer:

36 square units

Step-by-step explanation:

well the surface area is:

let's say that the surface of a cube is 1 squared units

so in the figure we have the faces:

up (blue)

down (not seen)

front (green)

back (not seen)

left (yellow)

right (not seen)

so the are of the blue is 6 and also is the down area

the area of the front is 6 and also is the back area

the area of the left is 6 and also the right area

so we have

[tex]S_a = 6+6+6+6+6+6\\\\S_a = 6*6\\\\S_a = 36[/tex]square units

Mr. Smith goes to the concession stand and buys 2 soft pretzels and 1 cheeseburger for $8.25. Mr. Martin goes to the same concession stand and buys 1 soft pretzel and 3 cheeseburgers for $13.50. Write a system of equations and solve to determine the cost of a cheesburger.

Answers

Answer:

$4.15

Step-by-step explanation:

Let the cost of a cheeseburger be x

Let the cost of a soft pretzels be y

If Mr. Smith goes to the concession stand and buys 2 soft pretzels and 1 cheeseburger for $8.25, this is expressed as;

x + 2y = 8.25 .... 1

Also, if Mr. Martin goes to the same concession stand and buys 1 soft pretzel and 3 cheeseburgers for $13.50, this is expressed as;

3x + y = 13. 50..... 2

The required equations are:

x + 2y = 8.25

3x + y = 13. 50

Find x and y by solving simultaneously:

From 1: x + 2y = 8.25

x = 8.25 - 2y ..... 3

Substitute 3 into 2

3(8.25-2y)+y = 13.50

24.75 - 6y+y = 13.50

24.75 - 5y = 13.50

-5y = 14.50 - 24.75

-5 y = 10.25

y = -10.25/-5

y = 2.05

Since x = 8.25 - 2y

x = 8.25 - 2(2.05)

x = 8.25 - 4.1

x = 4.15

Hence the cost of a cheesburger is $4.15

A rectangle that is 2 inches by 3 inches has been scaled by a factor of 7 if you want to cooy back to its original size by what scale factor should you use

Answers

Answer:

1/7

Step-by-step explanation:

Given that:

Using a scale factor of 7 ; the dimension of a rectangle is : 2 inches by 3 inches

In other to obtain the original size of the rectangle, all that is needed is to multiply the sacl d dimension by the reciprocal of the initi. Scale factor used, that is 1 / 7

This gives :

(2 inches by 3 inches) * 1/7

2/7 inches by 3/7 inches

Hence, required scale factor is 1/ 7

At which value(s) of x does the graph of the function F(x) have a vertical asymptote? Check all that apply. F(x) = (x-4)(x + 2)
A. X= 4
B. X = 2
C. x= 1 n
D. x= -4
E.x= -2
F. x=0

Answers

Answer: A and E.

Step-by-step explanation:

For a function of the form:

F(x) = h(x)/g(x)

It only has a vertical asymptote in the points where the denominator is equal to zero, this means that we must have g(x) = 0.

In this case, we have:

F(x) = (x-4)(x + 2)

As this function has no denominator, this will not have any vertical asymptote, then i suppose that the actual function is:

[tex]F(x) = \frac{1}{(x - 4)*(x + 2)}[/tex]

Using the same notation as above, we have:

g(x) = (x - 4)*(x + 2)

Then the vertical asympotes of F(x) will be on the values of x such that:

g(x) = 0.

As g(x) is already written in factorized form, we know that the zeros will be at the values of x that make one of the terms inside the parentheses equal to zero, these values are:

x = 4:

g(4) = (4 - 4)*(4 + 2) = (0)*6 = 0

and at x = -2

g(-2) = (-2 - 4)*(-2 + 2) = -6*0 = 0

Then the two asymptotes of F(x) are at x = 4, and x = -2

The correct options are:

A and E.
