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:
A
Step-by-step explanation:
∠ AOC = 90° and
∠ AOB + ∠ BOC = ∠ AOC , that is
x + 8 + 2x = 90
3x + 8 = 90 ( subtract 8 from both sides )
3x = 82 ( divide both sides by 3 )
x =
Then
∠ BOC = 2x = 2 × =
≈ 54.67° ( to 2 dec. places )
