Demarkus says that a store overcharged him on the price of the video game he bought. he thought that the price was marked 1/4 of the original price, but it was really 1/4 off the original price. he misread the advertisement. if the price of the game was $48, what is the difference between the price that demarkus thought he should pay and the price that the store charged him?

(x-5)1/2+5=2 what is a possible solution?

What is the inverse of the function f(x) = 2x + 1?

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)
