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>
<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>
<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>

hope this make sense :/
Hello There!
145 is 23.39% of 620
<u><em>HOW TO SOLVE</em></u>
<u><em></em></u>
<u><em>Equation: Y = P% * X</em></u>
<u><em>We need to solve our equation for "P"</em></u>
<u><em>P% = Y/X</em></u>
<u><em>P% = 145/620</em></u>
<u><em>p = 0.2339</em></u>
<u><em></em></u>
<u><em></em></u>
<u><em>Convert decimal to percent:</em></u>
<u><em>Percent = 0.2339 * 100 = 23.39%</em></u>
Answer:
area of this circle: 490.6 inch²
Step-by-step explanation:
area of circle: π(radius)²
Here the diameter is given 25 inch, so the radius will be half: 25/2 → 12.5 in
using the formula:
3.14(12.5)²
490.625 inch²
490.6 inch²____rounded to nearest tenth.
