Answer:
A5 . [tex]\frac{2}{7}[/tex]
Step-by-step explanation:
Given in ques as a inversely proportion to b/2
it can be written as a∝[tex]\frac{1}{b/2}[/tex]
Now we put a proportionality constant (k) here
so, a=k[tex]\frac{1x}{b/2}[/tex]
or a=[tex]\frac{k2}{b}[/tex]
Now for a= 1 and b= 10
1= [tex]\frac{2k}{10}[/tex]
10= 2k
or,k=5
Now agin for b= 35 and take k value as 5, we get a value
a=[tex]\frac{2*5}{35}[/tex]
so, a=[tex]\frac{2}{7}[/tex] Answer
