Yis directly proportional to the cube root of x. if x is increased by 200%, find the % increase of y.

y increases by 44.22%

Step-by-step explanation:

If y is directly proportional to cube root of x, then y can be written as

if x is increased by 200%, then

old x - 100%

new X - 300%

hence,

and new Y is

Thus,

y - 100%

Y - a%

Then

y increases by 44.22%

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

only 10/60 isn't equivalent

hope this : )
