The rate of discount, r, can be determined using the formula , where p is the regular price of an item and d is the discount, or amount saved off the regular price. find the rate of discount on a sweater with a regular price of $36 that is on sale for $27. if necessary, round to the nearest hundredth. 1.25 1.75 0.75 0.25

Which ordered pair (c, d) is a solution to the given system of linear equations- c+2d=13 -9c-4d=-15

What is negative 3/9 times negative 2/8 ?

For every corresponding pair of cross sections, the area of the cross section of a sphere with radius r is equal to the area of the cross section of a cylinder with radius and height 2r minus the volume of two cones, each with a radius and height of r. a cross section of the sphere is and a cross section of the cylinder minus the cones, taken parallel to the base of cylinder, is the volume of the cylinder with radius r and height 2r is and the volume of each cone with radius r and height r is 1/3 pie r^3. so the volume of the cylinder minus the two cones is therefore, the volume of the cylinder is 4/3pie r^3 by cavalieri's principle. (fill in options are: r/2- r- 2r- an annulus- a circle -1/3pier^3- 2/3pier^3- 4/3pier^3- 5/3pier^3- 2pier^3- 4pier^3)
