Answer:
Option A.
Step-by-step explanation:
Anastasia worked for = 7 hours per day
Number of weeks she worked = 52 weeks
Number of hours she worked = 7×52
= 364 hours
Per hour earning of Anastasia = $20
Total earning of Anastasia = 364×20
= $7280
Let the monthly expenses of Anastasia = $x
Then total expenses = $12x
At the end of the year total saving = Total earning - Total expenses
= $7280 - 12x
Since she saved $2000 in a year therefore, expression that represents the savings will be
2000 = 7280 - 12x
12x = 7280 - 2000
12x = 5280
x =
x = $440
Option A will be the answer.

Answer:
The practical domain of the function is [30,32].
Step-by-step explanation:
The given function is
where, p(h) represents the Vonda's weekly pay as a function of hours worked.
She pays a one time $250 chair rental fee, and earns $40 per hour that she works.
Domain is the set of all possible inputs.
The possible domain of the given function is all real numbers but the number of hours can not be negative, therefore h>0.
It is given that Vonda works between 30 and 32 hours per week at a hair salon. So,
Therefore practical domain of the function is [30,32].
Given:
In triangle GHI, h = 300 inches, G=30° and H=29º.
To find:
The length of i.
Solution:
We have, G=30° and H=29º.
Using angle sum property, we get
According to Law of sines,
Using Law of sines, we get
Multiply both sides by 0.8572.
Therefore, the length of i is about 530 inches.
