Which type of surface will produce the fastest race time? Concrete‚ sandpaper‚ or gravel? If I race a remote control truck on a concrete‚ sandpaper‚ and gravel surface‚ I think the truck will go faster on the concrete surface. 1. Gather all of your materials. 2. Using your measuring tape‚ measure 12 ft in distance from the starting point to the finish line. Make sure your area is flat and dry. 3. Stick pieces of tape at the beginning and end of your track to form a clear

Two Variable Inequality MAT 221 11 May 2012 The purpose of this week’s assignment is to determine how many maple rocking chairs the Ozark Furniture Company can make. We will also plot the inequalities of this on a graph. Here is the information and first set of problems for the text: Maple rockers. Ozark Furniture Company can obtain at most 3000 board feet of maple lumber for making its classic and modern maple rocking chairs. A classic maple rocker requires 15 board

Look Think Motion can be described using graphs. Graphs and charts are common tools used in science. To interpret graphs‚ read the axis labels as well as the numbers on the axis. The title should give you some clue as to the purpose of the graph. Next‚ examine the content. Try to describe the content in words‚ using “As ____(quantity on the x axis)‚ ____(type of change‚ such as increases or decreases)‚ ____ (quantity on the y axis) ___(type of change such as increases

Cartesian coordinates in three dimensions A three dimensional Cartesian coordinate system‚ with origin O and axis lines X‚ Y and Z‚ oriented as shown by the arrows. The tick marks on the axes are one length unit apart. The black dot shows the point with coordinatesX = 2‚ Y = 3‚ and Z = 4‚ or (2‚3‚4). Choosing a Cartesian coordinate system for a three-dimensional space means choosing an ordered triplet of lines (axes)‚ any two of them being perpendicular; a single unit of length for all three
