The Sales Manager for Chicken Shack restaurants is studying the sales figures for two new varieties of chicken sandwiches recently introduced at eight of its restaurants. For four weeks, three restaurants have been selling lemon-roasted chicken sandwiches. The other five restaurants have been selling barbecued chicken sandwiches for three weeks. During the testing period, 6,000 lemon-roasted chicken sandwiches were sold, and 7,200 barbecued chicken sandwiches were sold. Which of the two new chicken sandwiches should the sales manager report as having the better sales?

Answers

Using the average sales per restaurant, the sales manager should report the Lemon-roasted chicken sandwiches as recording better sales performance than the Barbecued chicken sandwiches.

What is the average?

The averages represent the total sales generated at the lemon-roasted and barbecued restaurants, respectively, divided by the number in each group.

The average is the same as the mean of a data set.  It is computed by the mathematical operations of addition and division.

Step-by-step explanation:

because in first piggy bank has 4 coins and second has 6 . difference=6-4=2

second has 6 coins and third has 9 . difference= 9 - 6 = 3 third has 9 coins and fourth has 13 . difference=13-9=4

fourth has 13 and fifth has 18 coins difference is 18 -13 =5

Two angles are complementary. If one angle is (x²-16x) and the other is (3x), thenwhat is the measures of the angles?

The smaller angle =
The larger angle =

Answers

Answer:

Complementary angles have a sum of 90°.

(x²-16x)+(3x) = 90

x² -13x - 90 = 0

(x-18)(x+5) = 0

x - 18 = 0 or x + 5 = 0

x = 18 or x = -5 (reject)

Substitute x into the angles.

18²-16(18) = 36

Smaller angle = 36°

3(18) = 54

Larger angle = 54°

A lake in East Texas was stocked with 3,000 trout in the year 2000. The number of fish in the lake is modeled by f(x) = 3000 + 100x, where x represents the number of years after 2000. Which of the following is the most reasonable domain and range for the function if domain is time, and range is number of fish?

Domain:

Range:

Answers

The Domain and the range of the function are given as

x ≥ 0, y ≥ 3000

What is the domain of a function?

This is the complete set of values that is used to represent the independent variable in the function. The independent variable that we have here is represented by x and it is 0.

What is the range of a function?

This is the set of the possible values that the dependent variable in the function is to have. The dependent variable is given by y.

The range of x would have to start from 0 for the range of all values of x. Hence x ≥ 0, while y is seen to be in  the form of y ≥ 3000 because this is the value of trout that was stocked.

I just need to know if the answer is B or D

Answers

Firslty, we need to find the function, whcih we can do by substituting one into the other:

[tex]f(g(x))=2(g(x))^2-1=2(\sqrt[]{x-2})^2-1=2(x-2)-1=2x-4-1=2x-5[/tex]

Now, for the domain we have more complicated approach.

We first have to find the domain for both f(x) and g(x).

The domain of f(x) is all real number, because it is a quadratic polynomial.

The domain of g(x) is all the real numbers except the x values that makes the square root interior negative, so all real numbers so that:

[tex]\begin{gathered} x-2\ge0 \\ x\ge2 \end{gathered}[/tex]

Now, the domain of the composite function f(g(x)) is the set of all the values of x in the domain of g(x) such that the corresponding g(x) is in the domain of f(x).

Since the domain of f(x) is all real numbers and g(x) is a real number function, all the values of g(x) will be in the domain of f(x), so we just need to check the values of x that are in the domain of g(x).

The domain of g(x), as we saw, is:

[tex]D=\mleft\lbrace x\mright|x\ge2\}[/tex]

And any value of x will give a g(x) that will be in the domain of f(x) so, the domain of f(g(x)) is:

[tex]D=\mleft\lbrace x\mright|x\ge2\}[/tex]

So, the correct alternative is:

[tex]\begin{gathered} f(g(x))=2x-5 \\ D\colon\mleft\lbrace x\mright|x\ge2\} \end{gathered}[/tex]

A woman has twice as many dimes as quarters in her purse. if the dimes were quarters and the quarters were dimes, she would have $1.20 more than she has now. how many of each type of coin does the woman have?

Answers

The number of Quarter coins that she has is 8 and the number of Dimes is 16.

It is given in the question that the woman has twice as many Dimes as the quarters in her purse.

We know that the value of Dimes is 0.10$ and the value of Quarters is

0.25 $

Let the number of Quarter coins is y and the number of Dimes coin be u.

According to the question above,

u = 2y  equation (i)

The total value z = 0.25y + 0.10u

Putting here the value of u from equation (i) we have,

z = 0.25y + 0.10(2y)

⇒ z = 0.25y + 0.20y

⇒ z = 0.45y equation (ii)

Now it has been mentioned that if the Dimes were Quarters and the Quarters were the Dimes, she would have $ 1.20 greater than she has now.

So we have,

z + 1.2 = 0.25u + 0.10y

Putting the value of u from above eqation (i),

z + 1.2 = 0.25(2y) + 0.10y

⇒ z + 1.2 = 0.50y + 0.10 y

⇒ z + 1.2 = 0.60y

Putting the value of z from equation (ii)

⇒ 0.45y + 1.2 = 0.60y

⇒ 0.45y - 0.60y = - 1.2

⇒ -0.15y = - 1.2

⇒ y = [tex]\frac{-1.2}{-0.15}[/tex]

⇒ y = 8

Therefore u = 2y

⇒ u = 2 x 8 = 16

Hence the number of Quarter coins is 8 and the number of Dimes is 16

Ryan collected 2,650 baseball cards, football cards, and hockey cards. he has 3 times as many baseball cards as football cards. he has 150 more hockey cards than football cards. how many baseball cards does he have? ryan has baseball cards.

Answers

The calculated answer after simplification in which Ryan has number of baseball cards is: 357 cards

How to simplify statement problems?

In mathematics, the statement based problems can be solved by forming the equations. And later, simplify those equation by equating to each other. This method is very common for the complicated problems to make the calculation easy.

According to the question, Ryan collected 2650 cards. In which, he has more baseball cards compared to football cards.

Now, let us assume, baseball cards be 'B'; football cards be 'F' and hockey cards be 'H'.

As per the question, the formed equation from the statement for the simplification is:

B + F + H = 2650

3B = F and H + 150 = F

Substituting above values in the formed equation to get the simplify answer,

B + 3B + 3B - 150 = 2650 ⇒ 7B = 2500 ⇒ B = 357

Now, the value of football cards is: F = 3(357) = 1071

And, the value of hockey cards is: H = 1071 - 150 = 921

Hence, after simplification Ryan has number of baseball cards is: 357 cards
