Answer:
94.5%
Step-by-step explanation:
Percent decrease can be represented as
[original price] * percentage = [new price]
When trying to find the percentage, you can manipulate the equation by dividing both sides by the original price to get:
percentage = [new price] / [original price]
In this case, this is represented by 192300/203400, or 94.5%

Answer:
C. Claire has 10 country CDs and 5 Jazz CDs
Step-by-step explanation:
means that 10 out of 15. So we can assume that in total she has 15 CDs and 10 of them are Country and the other is Jazz.

This means that two-thirds of her CDs are country music. So this would rule out A and B choices.
Now C is correct because 10 country plus 5 Jazz is equal to 15 CDs. So we have the correct total.
The answer is C.
Answer:
The sine and cosine functions have a period of 2π radians and the tangent function has a period of π radians. Domain and range: From the graphs above we see that for both the sine and cosine functions the domain is all real numbers and the range is all reals from −1 to +1 inclusive.
