Question

6. D is directly proportional to T.
When T = 3, D = 36
(a) Find the formula connecting D and T.

(b) Find T when D is 66.

Answer 1

D=kT

36=3k

k=12

D=12T

66=12T

T=22/4=11/2=5.5

:-)

Answer 2

Answer:

a)D=12T

b)D=5.5

Step-by-step explanation:

a) Because D=KT  AND K=12 SO D=12T.

b) Because D=12T to get T when you have D . You get  66/12 and this gives you 5.5.
