Researchers at the university of british columbia have measured muscle reaction times of 0.1 seconds for olympic sprinters. suppose the human chain consisted entirely of olympic sprinters with an average arm span of 6 feet. it would take the signal days to travel all the way around the world. round your answer to the nearest tenth of a day and enter only the number. (hint: first compute the number of people required to circle the globe, using 24,000 miles for the circumference of the earth and 5280 feet per mile.)

#1-20 state whether the angles are alternate interior, alternate exterior, vertical, or corresponding angles.

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?
