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
