1. Pi is usually referred to as 3.14, so the answer is 1
2. b) Endless
3. d) √5
4. a) 1/27
5. c) Irrational Numbers
I hope this helps! Let me know if you would like an explanation as to how I got the answers :)
In the first part, there are 10 fish total. 6/10 = 3/5 which means that there were 3/5 goldfish. When she buys two more, the total becomes 12 and 4/12 = 1/3 Hope this helps!
If lines are parallel then they have the same slope
This means that for line a to be parallel to line b both must have the slope of 1/4
Hope this helped!

Sin^2(x) + cos^2(x) = 1
sin^2(x) = 1 - cos^2(x)
Replace sin^2(x) in the equation with 1 - cos^2(x)
2(1 - cos^2(x)) - 5cosx + 1 = 0
2 - 2cos^2(x) - 5cosx + 1 = 0
2cos^2(x) + 5cos x - 3 = 0
Let cosx = y
2y^2 + 5y - 3 = 0
(2y -1)(y + 3) = 0
y = cosx so:
cosx = ½,
cosx = -3 (gives no solutions since cos domain is -1 to 1)
Therefore x = pi/3, (2pi - pi/3) = 5/3pi
