Question

x directly proportional to √y. when x=35,y=49. find x when y=25.​

Answer 1

Answer:

25

Step-by-step explanation:

x proportional to √y.

x = k√y => k = x / √y

Also Given x = 35 and y = 49

k = 35 / √49 = 35 / 7 = 5

Now when y = 25

x = k√y = 5 ×√25 = 5×5 = 25

The value of x when y is 25.
