When p = 12, t= 2, and s = 5. r = 18. If r varies directly with p and inversely with the product of s and t, what is the constant of variation? O col 1 2 O O 18

Constant of variation is: 15

Step-by-step explanation:

r varies directly with p and inversely with the product of s and t

It can be written as:

r ∝ p/st

When the proportionality symbol is removed, a constant is introduced which is called constant of variation

So

Putting p = 12, t= 2, and s = 5 and r = 18

Hence,

Constant of variation is: 15

the answer to the expression is 83

answer: approximately 206 bones

i hope this u out a branlist and a would be greatly appreciated :
