Matthew was collecting rocks and then weighing the results of his collection. The table below shows his results. Based on his results, which statement describes the relationship between r, the rocks collected, and w, the weight of the collection of rocks per quantity collected? A. The relationship is proportional because the ratio of w to r is constant. B. The relationship is not proportional because the ratio of w to r is not constant. C. The relationship is proportional because the ratio of w to r is not constant. D. The relationship is proportional because the difference between w and r is constant.

Nthe opening scene of the movie raiders of the lost ark, indiana jones replaces a golden statue with a bag of sand. the platform on which the statue is placed is designed to detect the mass of the statue. if the bag of sand has a different mass than the statue, then a mechanism triggers and destruction ensues. the density of gold is about 20\text{ g/cm}^320 g/cm 3 20, space, g, slash, c, m, start superscript, 3, end superscript. the density of sand can be estimated at 2.5\text{ g/cm}^32.5 g/cm 3 2, point, 5, space, g, slash, c, m, start superscript, 3, end superscript. the gold statue can be modeled as a cylinder with height 25\text{ cm}25 cm25, space, c, m and radius 8\text{ cm}8 cm8, space, c, m. in terms of \piπpi, what is the mass of sand indiana jones needs to avoid triggering the mechanism?
