There is a multiplication and division fact family with the numbers 2,4 and 8. write the four fact family members

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.)

25 ! the line of best fit is h = 5a + 86. predict the height at age 16. show your work.

Which of the following expressions cannot be simplified to x – 2?
