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