A is directly proportional to b. When a is 6, b is 72. Find b when a is 8. 3
adelina 88 [10]

Answer:

a)  <em>"K" is proportional Constant   K= 0.0833</em>

<em>b)     The value of b = 99.639</em>

Step-by-step explanation:

<u><em>Explanation</em></u> :-

Given   'a' is directly proportional to 'b'

                     a ∝ b

                <em>  a  =  k b ....(i)</em>

<em>where "K" is proportional Constant</em>

<u><em>Case(i)</em></u><em>:-</em>

<em>when a =6  and b=72</em>

<em>               a  =  k b     </em>

<em>          ⇒ 6 = k (72)</em>

<em>        ⇒  </em>K = \frac{6}{72} = \frac{1}{12} = 0.0833<em>      </em>

<u><em>Case(ii)</em></u><em>:-      </em>

<em> Given  a = 8.3  </em>

<em>           a  =  k b     </em>

<em>⇒   8.3 = 0.0833 ×b</em>

<em>⇒  </em>b = \frac{8.3}{0.0833} = 99.639<em></em>

<u><em>Final answer</em></u><em>:-</em>

a)<em>"K" is proportional Constant   K= 0.0833</em>

<em>b)     The value of b = 99.639</em>

<em></em>
