A photocopy machine is initially loaded with 5,000 sheets of paper. The machine starts a large job
and copies at a constant rate. After 20 minutes, it has
used 30% of the paper. Which of the following
equations models the number of sheets of paper, P,
remaining in the machine m minutes after the
machine started printing?
A p = 5,000 - 20m
B) p = 5,000 - 75m
m
c) p = 5,000(0.3) 20
m
D) p = 5,000(0.7) 20

Write two subtraction equations that are equivalent to 5 + 12 = 17.

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?
