A restaurant is an institution of business which prepares and provides clients with food and beverages. Although many restaurants now provide take-out as well as food delivery services, meals are often served and consumed on the premises.

A restaurant serves breakfast, lunch, and dinner. The restaurant offers a daily special. To estimate the percentage of customers who order the daily specials, the restaurant selected a random sample of customers who had lunch during 2 month period. From the results, the restaurant determined that 25% of these customers ordered the daily special. No generalizations can be made because the sample size is too small.

Therefore, the correct option is option A.

Answer:

he traveled 900 feet

Step-by-step explanation:

250 + 650 = 900

Mr. Carter traveled a total distance of 900 feet from his boat to where he ended up.

Here, we have to find the total distance that Mr. Carter traveled from his boat to where he ended up, we need to calculate the sum of the distances above and below sea level.

The distance above sea level is 250 feet (his house boat's level), and the distance below sea level is 650 feet (where he ended up after jumping).

Total distance traveled = Distance above sea level + Distance below sea level

Total distance traveled = 250 feet + 650 feet

Total distance traveled = 900 feet

Mr. Carter traveled a total distance of 900 feet from his boat to where he ended up.

The company must produce 25 t-shirts to break even.

Here, we are given that a company producing t-shirts charges $125 for the design and set up plus $5 per tee.

This means-

fixed cost of producing the t-shirts = $125

Variable cost of producing a t-shirt = $5

Let x be the number of t-shirts produced

Thus, the total cost of producing t-shirts will be-

Total cost = 125 + 5x

Further, the selling price of 1 t-shirt = $10

Thus, selling price of x t-shirts = $10x

Now, at the break even point, the profit is 0, this implies-

Selling price = cost price

⇒ 10x = 125 + 5x

10x - 5x = 125

5x = 125

x = 125/5

x = 25

Thus, the company must produce 25 t-shirts to break even.

The area of a sidewalk that surrounds a rectangle of 4 ft by 6 ft  is 56 ft²

The given situation can be depicted in the attached picture.

Recall the formula to calculate the area of a rectangle:

  A = l ⨉ w

Where:

l = length

w = wide

In the attached picture, the area of the sidewalk is the one with green color.

Notice that:

Area of sidewalk = area of bigger rectangle – area of smaller rectangle

Parameters of the bigger rectangle:

l = 6 + 2 + 2 = 10 ft.

w = 4 + 2 + 2 = 8 ft.

Area of bigger rectangle = 10 x 8 = 80 ft²

Parameters of the smaller rectangle:

l = 6 ft.

w = 4 ft.

Area of bigger rectangle = 6 x 4 = 24 ft²

Hence,

Area of sidewalk = 80 - 24 = 56 ft²

Answer:

A) The unit prices are the same.

Step-by-step explanation:

First convert dollars to cents to make the calculation easier

Package of 50 paper plates costs $2.50
$2.50 = 2.50 x 100 = 250¢
So the unit price, which is the price per paper plate = 250/50 = 5¢

Package of 80 paper plates costs $4.00
$4.00 = 4.00 x 100 = 400¢
So the unit price, which is the price per paper plate = 400/80 = 5¢

So the unit prices of both packages are the same

The location of the y value of R' after using the translation rule is -10

The translation rule is given as:

(x + 4, y - 7)

The pre-image of R is located at (-17, -3)

R = (-17, -3)

When the translation rule is applied, we have:

R' = (-17 + 4, -3 - 7)

Step-by-step explanation:

gradient = slope or several other words.

it describes how strongly a line (or tangent to a bent curve) is going up or down or ... if it is changing at all.

it is represented by the ratio

(y coordinate change / x coordinate change)

when going from one point on the line to another.

in our case, when going from A to B we have

x changes by -2k (from 3k to k).

y changes by -11 (from 8 to -3).

so, the gradient or slope is

-11/-2k = 3

11/2k = 3

11 = 3×2k = 6k

k = 11/6

A = (33/6, 8) = (11/2, 8)

B = (11/6, -3)

Answer:

1)  -5x² + 13x + 6

2) B(x)  =(4x + 1 )(2x + 3)

  A(x) = (5x +2)(3-x)

Step-by-step explanation:

1) Expand the equation by using distributive property. Then simplify  by combining the like terms.

A(x) = (3 -x)2² - (x -3)(7x+ 4) - 18 + 2x²

         = (3 - x)4 - [x*7x + x*4 - 3*7x - 3*4] - 18 + 2x²

         = 3*4 - x*4 - [7x² + 4x - 21x - 12] - 18 + 2x²

         = 12 - 4x - 7x² - 4x + 21x + 12 - 18 + 2x²

        = 2x² - 7x² -4x - 4x + 21x + 12 + 12 - 18

       = -5x² + 13x + 6

B(x) = (3x + 2)² - (x - 1)²

Identities:

(a + b)² = a² + 2ab + b² ; Here a =3x & b = 2

(m -n)² = m² - 2mn + n² ; Here m = x & n = 1

2) B(x) = (3x)² + 2*3x*2 + 2² - [x² - 2*x*1 + 1]

      = 9x² + 12x + 4 - [x² - 2x + 1]

      = 9x² + 12x + 4 - x²+ 2x - 1

     = 9x² - x² + 12x + 2x  + 4 - 1

     = 8x² + 14x +3

Product = 8*3 = 24

Sum = 14

Factors = 2 , 12    {2*12 = 24 & 2 +12= 14}

    = 8x² + 2x + 12x + 3    {Rewrite the middle term}

    = 2x(4x + 1) + 3(4x + 1)      

   = (4x + 1 )(2x + 3)

  A(x) = - 5x² + 13x + 6

       = -5x² + 15x -2x + 6

       = 5x(-x +3) +2 (-x + 3)

       = (5x +2)(3-x)

4) B(x) - 3 = 8x² + 14x + 3 - 3

                = 8x² + 14x

                = 2x *4x + 2x *7

                =2x(4x + 7)

Hence proved.

                           B(x) = 3

            8x²  + 14x + 3 = 3

        8x² + 14x + 3 - 3 = 0

           8x² + 14x         = 0

              2x(4x + 7)     = 0

2x = 0   or    4x + 7 = 0

 x = 0   or          4x = -7

Using scientific notation, the first step in simplifying the expression is given by:

a. Addition and subtraction requires the terms to be "like terms" with the same power of the base 10, so you would need to change the second number to (0.026 x 10^5).

A number in scientific notation is given by:

[tex]a \times 10^b[/tex]

With the base being [tex]a \in [1, 10)[/tex].

For two numbers in scientific notation to be added or subtracted, they need to have the same exponent, which removes options b and c.

Moving the second number for 10^3 to 10^5 would be equivalent to a multiplication by 100, hence we have to divide by 100 at the base, that is:

2.6 x 10^3 = (2.6/100) x 10^5 = 0.026 x 10^5.

Hence option a is correct.

Cameron's current service charge of $0.95 per song, and the new service charge of $0.89 per song and $12 fee for joining, gives;

To Formulate

The charges for songs on the current music service is, C1 = 0.95•s

The charges for the new download service is, C2 = 12 + 0.89•s

Where the $12 is the joining fee

When the cost is the same for both service, we have;

C1 = C2

Which gives;

The equation to represent when the cost for both service is the same is therefore;

0.95•s = 12 + 0.89•s

Computing;

The number of songs that gives the same costs is therefore;

0.95•s = 12 + 0.89•s

12 = 0.95•s - 0.89•s = 0.06•s

s = 12 ÷ 0.06 = 200

Interpreting the solution;

The interpretation is, the cost of songs downloaded on both service will be the same, when 200 songs are downloaded.
