A local hamburger shop sold a combined total of 449 hamburgers and cheeseburgers on Thursday. There were 51 fewer cheeseburgers sold than hamburgers. How many hamburgers were sold on Thursday?

Answers

Taking into account the definition of a system of linear equations, the  local hamburger shop sold 199 hamburgers on Thursday.

System of linear equations

A system of linear equations is a set of equations in which every equation is linear., in which two or more unknowns are related.

Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied.

This case

In this case, a system of linear equations must be proposed taking into account that:

"c" is the number of cheeseburgers sold on Thursday."h" is the number of hamburgers sold on Thursday.

You know:

A local hamburger shop sold a combined total of 449 hamburgers and cheeseburgers on Thursday. There were 51 fewer cheeseburgers sold than hamburgers.

The system of equations to be solved is

h + c= 449

h= c - 51

There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.

In this case, substituting the second equation in the first you get:

c - 51 + c= 449

c+ c= 449 + 51

2c= 500

c= 500÷2

c= 250

Remembering that h= c - 51, you get:

h= 250 - 51

h= 199

Finally, 199 hamburgers were sold on Thursday.

To solve for a missing side of a right angle, one can use trigonometric functions that will use the ratio of the other two known sides of the triangle in question.

For instance, using the trigonometric function of Sin can allow for the use of the opposite side and the hypotenuse to find the adjacent side. The Cos and Tan can also be used for the other sides.

This means that either of two sides (including the hypotenuse) can be used to find the other.

A company is going to make a water tank in the shape of a cylinder. As shown below, the tank will have a height of 3ft and a diameter of 8ft. The tank will be made from metal (including its top and bottom). If the metal costs $29 for each square foot, how much will the metal cost in total?

Answers

The total cost of the metal needed to cover the tank shaped like a metal is $5,099.36.

What is the total cost?

In order to determine the total metal cost, we are to first calculate the total surface area of the tank. Since the tank is a closed cylinder, we are to determine the total surface area of a cylinder.

The total surface area of a closed cylinder can be determined by adding the area of all its faces.

Total surface area of the closed cylinder = 2πr(r + h)

Where:

r = radius = diameter / 2 = 8/2 = 4ft

h = height

π = pi = 3.14

(2 x 3.14 x 4)(4 + 3)

25.12 x 7 = 175.84 ft²

Total cost of the metal = $29 x 175.84 = $5,099.36

4(h+45)=165
4h+45=165
45(h+4)=165
45h+4=165

Answers

Answer:

4h+45=165

Step-by-step explanation:

The cost of the skates does not fluctuate, therefore it always costs $45 no matter how long you use them for.

Answer:

4h + 45 = 165

Step-by-step explanation:

The question was a little hard to understand, but I made some assumptions based off of the answer choices and the information. If any of the assumptions I made sound incorrect, please don't use my answer!

Based off of the question and answer choices, I'm going to assume that Alan paid an initial price of $45 for the skis and then spent 4 hours skiing for an unknown hourly rate. The total amount of money she spent was $165.

Let h represent the hourly rate. Since Alan spent 4 hours skiing, 4 multiplied by h will represent the amount of money Alan paid for her skiing time.

Alan spent a total of $165. This means that the cost of the skis ($45) plus the cost of her ski time (4h) equals $165. This can be represented in this equation:
4h + 45 = 165

Answers

The members and non-members who pay the equal cost after 5 visits for the local zoo.

What is defined as the term equations?When one variable is determined to be equal to the other, the equation formula method is used to calculate the value of the a second variable.This second variable's value is the value that the others have same value.

For the given question;

The cost of membership of local zoo is $135 for members.

The parking cost is $3 for members.

Non-member admission cost is $25 for the zoo and $5 for the parking.

Let the number of number of visits paid the same amount be 'x'.

Then, the equation becomes.

Members: m = 135 + 3x

Non-Members: n = 25x + 5x

As, members and non-members are equal.

m = n

Put the values;

135 + 3x =  25x + 5x

135 + 3x = 30x

27x = 135

x = 5

Thus, members and non-members who pay the equal cost after 5 visits.

The sample percentage of orange candies is 0.22, and the standard error is 0.0195 and the expected 22% orange candies, give or take 1.95%.

a) It is assumed that there are 450 random candies with a p=0.22 percentage of orange candies.

As a result, the orange candy sample percentage should be 0.22.

b) Substituting the above data into the standard error formula, compute the needed value as shown below:

SE= √(p × q) ÷ n = √(0.22 × 0.78) ÷ 450 = 0.0195.

Answers

The dividends per share on each class of stock for each of the four years are as follows:

                       Cumulative Preferred       Common Stock

First-year,             $0.50                                  $0

Fourth year,         $0.60                                  $0.21

How are the dividends per share determined?

The dividends per share for each class can be determined by dividing the allocated dividend by the number of shares in the issue.

The allocated dividend to each class depends on the amount of dividend declared.  For cumulative preferred stock, when their fixed dividend cannot be sufficiently settled, the arrears are carried forward.

                               3% Cumulative Preferred       Common Stock

Par value                              $20                                         $25

(b x a) = -3i - j + 4z.(a x c) = a x c  = 1i - 2z.

b) The angle between vectors a and c is of 6.84º.

How to find a vectorial product?

A vectorial product between two vectors A and B is found from the determinant of a matrix, in which:

The first line is composed by the coordinates i, j and k.The second line is composed by the elements of vector a.The third line is composed by the elements of vector b.

Then for the vectorial product b x a, the matrix is:

[tex]\left[\begin{array}{ccc}i&j&k\\3&-1&2\\-2&2&1\end{array}\right][/tex]

Using a calculator, the determinant, which is the vectorial product, is given by:

b x a  = -3i - j + 4z.

For the vectorial product a x c, the matrix is:

[tex]\left[\begin{array}{ccc}i&j&k\\-2&2&-1\\-2&3&-1\end{array}\right][/tex]

a x c  = 1i - 2z.

The angle is found as follows:

sin(θ) = |a x c|/(|a| x |c|)

The norms are given as follows:

[tex]|a \times c| = \sqrt{1^2 + (-2)^2} = \sqrt{5}[/tex]. [tex]|a| = \sqrt{(-2)^2 + (2)^2 + (-1)^2} = 3[/tex]. [tex]|c| = \sqrt{(-2)^2 + (3)^2 + (-1)^2} = \sqrt{14}[/tex].

Hence:

[tex]\sin{\theta} = \frac{\sqrt{5}}{3\sqrt{14}}[/tex]

[tex]\theta = \sin^{-1}{\left(\frac{\sqrt{5}}{3\sqrt{14}}\right)}[/tex]
