On monday, it took helen 3 hours to do a page of science
homework exercises. the next day she did the same number
of exercises in 2 hours. if her average rate on monday was p
exercises per hour, what was her average rate the next day, in
terms of p?

2/3 p because 3 hours the first day then 2 the next day which makes it 2/3.

1.   an exact solution requires a radical solution - no decimal approximation.2. (a)4x^3 = 756x^3 = 756/4 = 189x =   cube root of 189 =   5.74   to nearest hundredth answer(b)   189 = 3*3*3*7   so we can write the cube root of 189 as 3∛7 answerchecking (a) 4*(5.74^3 =   756.48   which is very close(b)   4* ((3∛3)^3   = 4*189   = 756   - spot on! 3. i would use solution b because the original question asked for an exact solution.
