R is inversely proportional to A R = 12.1 when A =1.5 a) work out a formula connecting R and A

The formula is connecting R and A

The value of 'K' = 18.15

Step-by-step explanation:

Step(i):-

Given that R is inversely proportional to A

      R ∝ 1 / A

Given  R = 12 .1 and A = 1.5

      K = 12.1 × 1.5

     K = 18.15

The value of 'K' = 18.15

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8
