Recall that r^2 = x^2 + y^2, so that r = sqrt(x^2+y^2).
y
r = 3 sin g becomes sqrt(x^2+y^2) = 3*-----------------------
sqrt(x^2+y^2)
Squaring both sides,
9y^2
x^2+y^2 = -----------------
x^2 + y^2
If this is correct (and I'm not convinced that it is), then (x^2+y^2)^2 = 9y^2
shows the relationship between x and y. Can anyone improve on this result?
Step-by-step explanation: 29-8=21 so im guessing just subtract bc from Ac and that's your evidence maybe?
Answer:

Step-by-step explanation:
This is the answer because:
1) 185 equals to
because 18% is equal to 0.18 which is
2)
to it's lowest terms is 
3) It's lowest terms is
because 18/2 is 9 and 100/2 is 50
4)
can't be simplified any further because 9 and 50 don't have any common factors
Hope this helps! :D
Answer:
Half a pound.
Step-by-step explanation:
To find the number of pounds he ate, multiply the fractions.

He ate 1/2 a pound.
X=percentage in decimal
30x=6
30/30x=6/30
x=1/5=.20
.20=20/100=20%
20%
