Calculate percentage change

from V1 = 41700 to V2 = 63000

(V2−V1)|V1|×100

=(63000−41700)|41700|×100

=2130041700×100

=0.510791×100

=51.0791%change

the length of a rectangle is 9 units more than the width of the rectangle, w. if the width of the rectangle is more than 20 unit
Delvig [45]

Answer:

W>20

Step-by-step explanation:

Let

L-----> the length of a rectangle

W---> the width of a rectangle

we know that

L=W+9 -----> equation A

W>20 -----> inequality B

The inequality B represent the equation that could be used to find the possible values of the width

The solution for the width of the rectangle  is all real numbers greater than 20 units

I need help with this please. :) thanks
IgorC [24]

Answer:

d.  V = π(x^3 + 90x^2 + 2,400x  + 20,000)

Step-by-step explanation:

volume of cylinder = πr^2h

We have r = x + 20; h = x + 50

V = π(x + 20)^2(x + 50)

V = π(x^2 + 40x + 400)(x + 50)

V = π(x^3 + 50x^2 + 40x^2 + 2000x + 400x + 20,000)

V = π(x^3 + 90x^2 + 2,400x  + 20,000)
