Answer:
Robin= 750
Sharon= 720
Step-by-step explanation:
let the total marks obtained be X
from question, Robin = 5X/6
Shaon= 4X/5
then, 5X/6= 4X/5+30
or, 5X/6= 4X+150/5
or 25X=24x+900
or,X= 900
therefore robin=750
Shaon = 720
Well 9 3/4 is 9.75 and 27 1/2 is 27.5 so if we take 27.5 and subtract 9.75 you get 17.75 and then all you have to do is 17.75/2 which is 8.875 so the answer would be 8.875 inches on either side
<em>≈ 24 cm</em>
- <em>Step-by-step explanation:</em>
<em>Hi there !</em>
<em>c = 2πr } => c = πd => d = c/π</em>
<em>2r = d</em>
<em>replace c ; π</em>
<em>π =3.14</em>
<em>d = 74cm/3.14</em>
<em>= 23.5668</em>
<em>≈ 24 cm</em>
<em>Good luck !</em>
