50 points for this!!! The Garcia family has two cars. Last week, the first car consumed 30 gallons of
gas and the second consumed 25 gallons of gas. The two cars drove a
combined total of 1,250 miles, and the sum of their fuel efficiencies was 45
miles per gallon. What was the fuel efficiency of each of the cars last week?
First car: 25 miles per gallon
Second car: 30 miles per gallon
First car: 25 miles per gallon Second car: 20 miles per gallon

Heather is a cashier. she can ring up 1212 customers in 99 minutes. at this rate, how many minutes does it take her to ring up 44 customers?

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)
