The graph shows Linda's math scores versus the number of hours spent doing math homework. A graph titled Lindas Math Scores shows Hours of Practice in a Week on x axis and Math Scores on y axis. The x axis scale is shown from 0 to 5 at increments of 1, and the y axis scale is shown from 0 to 50 at increments of 5.The ordered pairs 0, 10 and 0.5, 15 and 1, 20 and 1.5, 18 and 2, 25 and 2.5, 26 and 3, 29 and 3.5, 32 and 4, 35 and 4.5, 45 and 5, 50 are shown on the graph. A straight line joins the ordered pairs 0, 10 and 5, 45.7.

What will most likely be Linda's approximate math score if she does math homework for 7 hours a week?

62.5 points
77.5 points
82.5 points
93.5 points

Somone me i want to know what 18 hours out of 24 hours in a fraction

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)

What is the explicit formula for this sequence -7, -4, -1, 2, 5
