The percentage change of a ratio of two variables is approximately the percentage change in the numerator _____ the percentage c

olchik [2.2K]

Answer:

"The percentage change of a ratio of two variables is approximately the percentage change in the numerator minus the percentage change in the denominator."

Step-by-step explanation:

The percent change in a number is determined by dividing the difference between the new number and original number by the original number and multiplying the result by 100.

Suppose the original ratio of two numbers is: $\frac{25}{100}$ .

And the new ratio is: $\frac{75}{100}$

The percent change is:

$Change\%=\frac{75-25}{100}\times100=\frac{50}{100}\times100=50\%$

Thus, the complete statement is:

"The percentage change of a ratio of two variables is approximately the percentage change in the numerator minus the percentage change in the denominator."

Answer:

V = 2143.57 cm^3

Step-by-step explanation:

We want to find the volume of the sphere

V = 4/3 pi r^3 where r is the radius and pi = 3.14

V = 4/3 ( 3.14) ( 8)^3

V = 2143.57333 cm^3
