A large rectangular tank has a base that is 2 meters wide and 3 meters long. Initially it contains 24 m3 of red paint. Starting at t = 0 blue paint enters at a rate of 6t m3 per hour,
and red paint enters at a rate of 6 m3 per hour.
(a) How many hours until the tank contains equal amounts of red and blue paint ?
(b) How quickly (in m/hr) is the depth of paint in the tank rising after t hours ?
(c) What is the average volume (in m3)
of paint in the tank during the first two hours

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
