Answer:
$4.16
Step-by-step explanation:
To solve this problem, we need to find 15% of $27.70. To do that, we just multiply 27.70 by the decimal form of 15%.
First, change 15% into a decimal:
15 -> -> 0.15
Now, lets multiply:

This means Square root (^1/2). this is kind of hard to read. anyways. 32^(1/2) separates into 4^(1/2) and 8^(1/2), which further separates into 4^(1/2) and 2^(1/2), root 4 becomes 2, their are two root 4's, so you get 2 x 2, and you are left with 2^(1/2) now why go to all this trouble. because now you can multiply the 4 you created (2x2) times, the 7... giving you 28*2^(1/2) now subtract it from the the other one with root 2. -5*2^(1/2), giving you 23*2^(1/2)-...idk what that last bit is. if its a odd number then this is the end of the problem, if you can get it to root 2. then do that and simplify.

Answer: Choice C) y = 30/x
Inverse variation equations are of the form y = k/x. In this case, k = 30. We can rearrange the format to get x*y = k after multiplying both sides by x. So y = 30/x can be turned into x*y = 30.
Answer:
y = 8
Step-by-step explanation:
adjacent/hypotenuse = cos(x)
4 / y = cos(30)
y = 4 /cos(30)
y = 8
