a varies directly as t and inversely as square of Y. if a = 24 when Z= 8 and Y= 10 find "A" when Z= 2 and Y= 5
i varies directly as a and inversely as R.
if I= 20 when E= 100 and R= 10 find "I" when A= 75 and R= 50
I kinda need help- Yung matinong answer po sana keep safe po ^^

First you neer to write the mathematical sentence into equation.
1.) A=kZ/(Y^2)
*A=24 when Z=8 and Y=10,
24=k(8)/(10^2)
24=8k/100
2400=8k
k=300
thus,
when z=2 and y=5,
A=kZ/(Y^2)
A=(300)(2)/(5^2)
A=600/25
A=24
