Answer:
cm per minute.
Step-by-step explanation:
We have been given that a box has a width of 10 cm and a length of 17 cm. The volume of the box is decreasing at a rate of 527 cubic cm per minute, with the width and length being held constant.
We know that volume of a cuboid is length times width times height.

Upon substituting our given width and length, we will get:


Now, we will find derivative of volume with respect to time as:

Since the volume of the box is decreasing at a rate of 527 cubic cm per minute, so we will substitute
as:



Therefore, the rate of change in height is
cm per minute.
Answer: 12 hours and 24 Minutes
Step-by-step explanation:
7*60 = 420
810/420 = 1.9285
93- 100 = 53-60
subtract 40 from 93.
1.53*8 = 12.24
Answer: 12 hours and 24 Minutes
% of decrease would be 100 - (22*100)/28
=100-78.57 = 21.43%
