Isra was selling tickets at the middle school dance. At the end of the evening, she picked up the cash box and noticed a dollar lying on the floor next to it. She said, “I wonder whether the dollar belongs inside the cash box or not.”
The price of tickets for the dance was 1 ticket for $5 (for individuals) or 2 tickets for $8 (for couples). She looked inside the cash box and found $200 and ticket stubs for the 47 students in attendance. Does the dollar belong inside the cash box or not?
Create 2 equations, one for the money and one for the number of tickets. Then use graphing, substitution, or elimination to find the variables.

What is the range? can’t seem to find it out

Rewrite 9 log, x2 in a form that does not use exponents. 9log, x = log, x

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)
