Answer:

Step-by-step explanation:
Deepak charges for each Job = $30
An additional charges for working each hour = $15
Let x be the number of hours he worked for each job.
So,additional charges for working x hours = 15 x
So,he earns in total at each job = 
We are also given that He only accepts jobs if he will earn at least $90 the job.
This means he must earn $90 or more than that .
So, the inequality becomes:

Hence an inequality to determine x, the number of hours he must work during each job in order to accomplish this is

Answer: x < 3
<u>Step-by-step explanation:</u>
4(x + 3) < 3(x + 5)
4x + 12 < 3x + 15 <em> Distributed</em>
x + 12 < 15 <em>Subtracted 3x from both sides</em>
x < 3 <em>Subtracted 12 from both sides</em>
A polygon inscribed in a circle, luckily, has a derived formula already. It is:
A = (nr²/2)[sin (360/n)]
where n is the number of sides of the polygon and r is the radius of the circle. For this problem, n = 100 and r = 1. Substituting this to the equation,
A = (100(1)²/2)[sin (360/100)]
A = 3.14 square units
Thus, the 100-gon has an area of 3.14 square units.
