Mr. Smith goes to the concession stand and buys 2 soft pretzels and 1 cheeseburger for $8.25. Mr. Martin goes to the same conces

polet [3.4K]

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

If f(x) = 1 – x, which value is equivalent to |f(i)|?l

LenaWriter [7]

Answer:

Square root ( 2 )

Step-by-step explanation:

We have to determine which value is equivalent to | f ( i ) | if the function is: f ( x ) = 1 - x. We know that for the complex number: z = a + b i , the absolute value is: | z | = sqrt( a^2 + b^2 ). In this case: | f ( i )| = | 1 - i |. So: a = 1, b = - 1. | f ( i ) | = sqrt ( 1^2 + ( - 1 )^2) = sqrt ( 1 + 1 ) = sqrt ( 2 ).

Getting along with coworkers and bosses Alderfer renamed the need for getting along with coworkers and bosses into the category

Leokris [45]

Incomplete question. The full question read;

Provide the missing category labels from Maslow's theory for the following work scenarios, and answer the related question on Alderfer's theory.

Work Example

Getting along with coworkers and bosses

Maslow's Need Category ____

Alderfer's ERG Theory Alderfer renamed the need for getting along with coworkers and bosses into the ______category of needs.

Getting a promotion for a job well done

Maslow's Need Category ____

Securing another position after being let go from a previous job

Maslow's Need Category ____

Answer:

Maslow's Need Category = love and belonging need (social belonging need); Alderfer's ERG Theory renamed to relatedness
Self-esteem need
Safety need

Step-by-step explanation:

According to Maslow's hierarchy of needs, in a scenario where someone (including a worker) is able to get along with coworkers and bosses, they have achieved the social belonging need.

Alderfer after studying Maslow's hierarchy decided to rename or in other categorize the social belonging need to "Relatedness". In other words, the individual has a need to be "related," "to belong."

While "getting a promotion for a job well done" in Maslow's hierarchy falls under the self-esteem need which is best illustrated when the individual has received recognition, a prize, and the likes.

Achieving Job security also falls under Maslow's safety need. That is why we can categorize "securing another position after being let go from a previous job' as belonging to the "Safety need".
