answer loud and proud
the reason this is my last one is bc of toxic 9 yr olds that report me after this I may not be able to ask anything ever again
but I prefer using my last question on you guys so enjoy
(also ik this is not mathematics)

At a sand and gravel plant, sand is falling off a conveyor and onto a conical pile at a rate of 16 cubic feet per minute. the diameter of the base of the cone is approximately three times the altitude. at what rate is the height of the pile changing when the pile is 12 feet high? (hint: the formula for the volume of a cone is v = 1 3 πr2h.)

[15 points, algebra 2]simplify the complex fraction and find the restrictions.

Aquadratic equation in standard from is written ax^2= bx+c, where a,b and c are real numbers and a is not zero?
