Two parallel lines, e and f, are crossed by two transversals. horizontal and parallel lines e and f are cut by transversals c and d. all angles are described clockwise, from uppercase left. at the intersection of lines e and c, the angles are: 1, 2, 4, 3. at the intersection of lines f and c, the angles are 5, 6, 8, 7. at the intersection of lines e and d, the angles are: 9, 97 degrees, 12, 11. at the intersection of lines f and d, the angles are 13, 14, 16, 15. what is the measure of angle15? mangle15 = 77° mangle15 = 83° mangle15 = 93° mangle15 = 97°

James wants to promote his band on the internet. site a offers website hosting for $4.95 per month with a $49.95 startup fee. site b offers website hosting for $9.95 per month with no startup fee. for how many months would james need to keep the website for site a to be a better choice than site b?

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?
