Answer:
A. 112.5°C
Step-by-step explanation:
Use the inverse variation equation, y = [tex]\frac{k}{x}[/tex]
Replace y with T, and replace x with V:
T = [tex]\frac{k}{V}[/tex]
Plug in 90 as T and 25 as V, then solve for k:
T = [tex]\frac{k}{V}[/tex]
90 = [tex]\frac{k}{25}[/tex]
2250 = k
So, the equation is T = [tex]\frac{2250}{V}[/tex]
Plug in 20 as V and solve for T:
T = [tex]\frac{2250}{V}[/tex]
T = [tex]\frac{2250}{20}[/tex]
T = 112.5
So, the temperature will be A. 112.5°C
