At the beginning of the year, Serenity had $90 in savings and saved an additional $13 each week thereafter. Andrew started the year with $40 and saved $18 every week. Let SS represent the amount of money Serenity has saved tt weeks after the beginning of the year and let AA represent the amount of money Andrew has saved tt weeks after the beginning of the year. Write an equation for each situation, in terms of t, t, and determine the number of weeks after the beginning of the year until Serenity and Andrew have the same amount of money saved.

Need same math paper but the back now i hope your able to read it cleary i need with hw

Typically a point in a three dimensional cartesian coordinate system is represented by which of the following answers in the picture !

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?
