Answer:
There are 9 terms, and the common difference is 11.
Step-by-step explanation:
The sum of the first n terms of an arithmetic sequence is:
S = n (a₁ + aₙ) / 2
where a₁ is the first term and aₙ is the last term.
252 = n (-16 + 72) / 2
n = 9
The nth term of an arithmetic sequence is:
aₙ = a₁ + d (n−1)
where d is the common difference.
72 = -16 + d (9−1)
d = 11
There are 9 terms, and the common difference is 11.
Answer:
139
Step-by-step explanation:
if one side is 139 the other side is 139
<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).
You first make it as
, then simplify it by the greatest common divisor (which comes out as 2, since 58=29*2 and
