<u>Find fraction of snappers and catfish:</u>
1/3 + 2/9 = 3/9 + 2/9 = 5/9
<u>Find fraction of goldfish:</u>
1 - 5/9 = 4/9
4/9 = 40 goldfish
1/9 = 40 ÷ 4 = 10
9/9 = 10 x 9 = 90
Answer: 90 fish in the tank
Answer:
Y = 10.25 or 10.247
Step-by-step explanation:
Alright So use the Formula A^2 + B^2 = C^2
You have one leg and the hypotenuse so first you are going to find 19 ^2 = 361.
Next, you need to find 16^2 = 256.
Last but not least, you subtract the leg from the hypotenuse, which equals 361-256=105
Finally, you take 105 and find its square root.
And depending on how far you round it down, your answer would be 10.25(that is in tenths), or 10.247(which is rounded to hundredths)
Hope this helps!
<span>A 5.0 L vessel holds 3.0 mol N2, 2.0 mol F2, and 1.0 mol H2 at 273 K. What is the partial pressure of fluorine?
P = nRT /V
P = 6(0.08206)(273) / 5.0
P = 26.88 atm
x(F2) =2/6 = 0.33
Partial pressure = 8.96 atm = 907 kPa

Answer:
x=-4/9, y=-74/9.
Step-by-step explanation:
y=32x+6
y=14x-2
-----------
32x+6=14x-2
32x-14x+6=-2
18x+6=-2
18x=-2-6
18x=-8
x=-8/18
simplify
x=-4/9
y=14(-4/9)-2=-56/9-2=-74/9
