Suppose that y is inversely proportional to square root of x.
FromTheMoon [43]

Answer:

i) k = 36.8

ii)y = 36.8/square root of x

iii)y = 1.4

Step-by-step explanation:

If y is inversely proportional to square root of x;

then the two variables are related by,

y = k/ square root of x

i)Value of k when...x = 8 and y = 13,

substitute into the equation above..so as to find the value of k

13 = k/square root of 8

;k = 13 × square root of 8

;k = 36.8

ii)Then substitute the value of k with...36.8

y = 36.8/square root of x

iii)If x = 27...then y =;

y = 36.8/27

y = 1.4

What is 21/35 in simplest form? Show steps in simplifying it.
Aleks04 [339]
21/35 in simplest form is 3/5 because you need to find the GCF first, then divide by it. the greatest common factor in this case is 7, so you need to divide 21 and 35 by seven.

21/7=3
35/7=5
