Answer:
Katie is correct. You would take 20% of $22.50 (22.5 multiplied by .2). You would get $4.50 off of the book with the discount. So you would subtract 4.5 from 22.5 and get $18. Then you would take 10% of $18 for the sales tax. (18 multiplied by .1). You would get $1.80 towards sales tax. you would then add $1.80 to $18 and get $19.80

Answer:
.
Step-by-step explanation:
Let x represent height of the cone.
We have been given that Sand pouring from a chute forms a conical pile whose height is always equal to the diameter.
We know that radius is half the diameter, so radius of cone would be
.
We will use volume of cone formula to solve our given problem.

Upon substituting the value of height and radius in terms of x, we will get:



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


Upon substituting
and
, we will get:




Therefore, the sand is pouring from the chute at a rate of
.
