Answer:
B
Step-by-step explanation:
Answer: a=1 b=3
Step-by-step explanation: the x for each of the points are 1 and 3
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>

Or for this and any other problem . every percentage is out of a 100
soooo ,
20 | 100 %
10 | 50 %
5 | 25 %
1 | 5 %
SOOO
10 + 5 = 15 50 % + 25 % = 75 % , so know we know 15/20 is 75 percent
but you need 18/20 not 15/20 , so 1 equals 5 % in this problem
1+1+1 = 3 5+5+5 = 15
15 + 3 = 90 75 + 15 = 90 , 18/20 = 90%
I know its probably alot but I wanted to show you all I did , so that it could maybe help you in the future , just gotta plug in different numbers
