Step-by-step explanation:
<u>Given</u>
- Base = 1.2 m²
- Height = h
- Number of fish = 6
- Density = 4 fish/m³
<u>Minimum volume required:</u>
<u>Lowest water height:</u>
- V= bh
- h = V/b
- h = 1.5/1.2 = 1.25 m
We can setup an equation for this.
Boys to Girls = 2:7
Boys = x
Girls = 250+x
Setup the ratio
x:(250+x) = 2:7
x / (250+x) = 2/7
7x = 500+2x
7x-2x = 500
x = 500/5 =100
