he volume of a fish tank is 50 cubic feet. If the density is 0.2 fish over feet cubed, how many fish are in the tank?
V125BC [204]

There are 10 fish in the tank

<em><u>Solution:</u></em>

Given that, volume of a tank is 50 cubic feet

Density is 0.2 fish over feet cubed

<em><u>To find: Number of fish in the tank</u></em>

Number of fish in the tank is found by multiplying the volume of tank and density

<em><u>The formula is given by:</u></em>

\text{Number of fish} = \tex{\text{volume of tank}} \times {\text{density of fish over feet cubed}}

<em><u>Substituting the given values, we get</u></em>

\text{Number of fish} = 50 ft^3 \times \frac{\text{ 0.2 fish}}{ft^3}\\\\ \text{Number of fish} =  50 \times 0.2 \text{ fish }\\\\ \text{Number of fish} = 10 \text{ fish }

Thus there are 10 fish in the tank

Licemer1 [7]
The interest is compounded quarterly because the formula is
A=p (1+r/k)^kt
A it's 18810.67 but I will assume it's unknown ?
P present value 7350
R interest rate 0.045
K compounded quarterly 4
Now solve the formula as the interest is compoundedquarterly
A=7,350×(1+0.045÷4)^(4×21)
A=18,810.67
