The density of a fish tank is 0.4 fish over feet cubed . there are 12 fish in the tank. what is the volume of the tank?

=30 ft³

Step-by-step explanation:

From the scenario given the formula for density of the fish pod is

ρ= no. of fish/ volume

Making volume the subject of the formula we obtain the following equation:

Therefore volume = no.of fish/ρ

Using the values provided in the question:

=12 fish/0.4 fish/ft³

=30 ft³

= 4.8

if x = 1, then the answer is 3.5

answer:

step-by-step explanation:

here, the total dishes = 10

dishes having meat = 3 ( chicken, meatloaf and hamburger )

thus, the probability of having meat on the chosen dishes = number of dishes having meat / total dishes

=

therefore, the probability of not having meat = 1- the probability of having meat on the chosen dishes

=

=

=

⇒ option b is correct.
