The water in the aquarium is a rectangular prism with dimensions 20, 12 and h (where the height is unknown).
We know that the volume is the product of the dimensions, and that it is 2400, so we have

Answer:x=20/y
Step-by-step explanation:
x α 1/y
removing the constant of proportionality sign α and replace it with =k
x = k/y
x=10 y=2
10 = k/2
Cross multiply
10x2=k
20=k
k=20
Substitute k=20 in x=k/y
x=20/y.........required equation

Answer:
Option C is correct
a + 0 = a
Step-by-step explanation:
Additive identity:
For any real number x,

We have to find an example of the additive identity from the given options.
Option A.
a+(-a) = 0
Which does not follow the additive identity.
Option B.
a+0 = 0
which does not follow the additive identity.
Option C.
a+0 = a
this equation follows the additive identity.
Therefore,an example of the additive identity is, a + 0 = a
