Answer:
John- 375
Karen- 125
Step-by-step explanation:
Answer 1...
j =3k
2j + k = 875
substituting the first eqn into the 2nd
2(3k) + k = 875
6k+ k =875
7k = 875
k =875/7 =125
thus j = 3(125) =375
Step-by-step explanation:
Given that,
Radius of circle, r = 38 cm = 0.38 m
It rotates form 10 degrees to 100 degrees in 11 seconds i.e.


Let
is the angular velocity of the particle such that, 


We need to find the instantaneous velocity of the particle. The relation between the angular velocity and the linear velocity is given by :


v = 0.053 m/s
So, the instantaneous velocity of the particle is 0.053 m/s. Hence, this is the required solution.

In math, when you see the word "of" it usually means "times".
So the question is:
<u>2/3 times something = 10</u>
Multiply each side of the equation by 3 :
2 times something = 30
Divide each side by 2 :
<em> something = 15</em>
