Question

if w is inverse proportional to t and w =28 when t =9 then find the value of w when t=12​

Answer 1

Answer:

w = 21

Step-by-step explanation:

According to the problem,

when w = 28, t = 9 and w is inversely proportional to t

thus, w*t = k

$w \times t = k \\ = > 28 \times 9 = k - - - - - - (k \: is \: a \: constant)$

thus, when t = 12, then,

$w = \frac{k}{t} \\ = > w \: = \frac{28 \times 9}{12} = 21$
