That is true. Let's say there are 100 fish. If half the fish are zebra danios then there are 50 zebra danios fish. If there are 50 fish left, and there are 2 times as many catfish as there are fancy guppies, then 33.33 of them are catfish and 16.66 of them are fancy guppies. Since one third of 100 is 33.33, then 1/3 of the fish are catfish.
The standard equation is 4p(x-h) = (y-k)^2 where |p| = focal distance |4p| = focal width.
<span>x=-1/8y^2
-8x=y^2
4*(-2)(x-0) =( y-0)^2
p = -2, h=0, k=0</span><span>
focal width = |4*(-2)| = 8
The answer to your question is that the length of the focal width is equal to 8.</span>
Answer:
8.1240384 i
Step-by-step explanation:
"Bucket method"
.. (4)*(14%) + (x)*(8%) = (4 +x)*(10%) . . . . . liters and % are in each "bucket"
.. 56 +8x = 40 +10x . . . . . multiply by 100, eliminate parentheses
.. 16 = 2x . . . . . . . . . . . . . . add -40-8x, then divide by 2
.. 8 = x
8 liters of 8% lemonade should be added to make the mixture 10% lemon juice.
