Answer:

Option A, Shannon paid $ 7 per hour to labor than Joni

Step-by-step explanation:

Total amount paid by Shannon = $339.50

Total cost of 3.5 hours of labor paid by Shannon =($339.50- $112)

Total cost of 3.5 hours of labor paid by Shannon = $227.5/3.5

Total cost of 1 hours of labor paid by Shannon  $65 per hour

Total amount paid by Joni = $455

Total cost of 2.5 hours of labor paid by Joni =  $455- $$310

Total cost of 1 hours of labor paid by Joni = $145/2.5

Total cost of 1 hours of labor paid by Joni = $ 58

Hence, Shannon paid $ 7 per hour to labor than Joni

Option A is correct

A hydrogen atom is about 5×10 to the -11 power
Olegator [25]

Factors are numbers that can be multiplied by an integer to obtain the desired integer

The size of the human hair is <u>1.0 × 10⁻⁴ meters </u>

Reason:

The given parameters are;

The size of an hydrogen atom is 5 × 10⁻¹¹   meters

The width of the human hair is 6 times as big

Therefore, we have;

The width of the human hair is 2 × 10⁶ times as big, therefore, we have;

The size of the human hair = 5× 10⁻¹¹ × 2 × 10⁶ = 1.0 × 10⁻⁴

The size of the human hair is <u>1.0 × 10⁻⁴ meters</u>

Is it wise for a firm to employ a worker at $20 per hour when another worker does the same job for $10 per hour?
vekshin1
<span>For me,

It would be a rational decision if the first worker was more than twice as productive as the second worker.</span>

This can happen in real life, for example 2 workers are hired to do the same type of job but one worker graduated with honors, the company can give a higher pay to the worker with honors compared with the other one who graduated. 

It is up to the company on how much they would pay their workers as long as it is above the minimum wage. Though there might be hurt feelings among the workers if they each knew how much they are paid for, it is also better for the company to inform workers that they are paid this certain amount because of the following reasons (graduated w/ honors).
