Answer: 
Step-by-step explanation:
Given: Density of tank = 0.4 fish over feet cubed.
We know that, 
Therefore,

Hence, the volume of the tank = 
I believe you meant: Use completing the square to determine the center and radius of the circle represented by this equation: <span>X^2+y^2-10x+6y=15
x^2 - 10x + 25 - 25 + y^2 + 6y + 9 - 9 = 15
Then:
(x-5)^2 + (y+3)^2 = 24 = 2sqrt(6)
This circle is centered at (5,-3) and has radius 2sqrt(6).</span>
Answer:
20
Step-by-step explanation:
first do 75/50 = 1.5
then multiply red by 1.5
13 landed on red so
13 x 1.5 = 19.5
but since you round up it is 20
If the value of a is positive, the line slopes upwards.
