Suppose the Cote family truly enjoys digestive biscuits.
Late one night, Papa Cote ate one-sixth of the family's digestives.
Early the next morning, Mama Cote ate one-fifth of the remaining biscuits.
Shortly thereafter, Brother Cote consumed one-quarter of the delicious snacks left.
At lunchtime, Sister Cote devoured one-third of the remaining tasty treats.
Finally, Baby Cote ate one-half of the remaining digestive biscuits.

How many delightful digestive biscuits were at first?

I can't quite figure out how to solve this... I would imagine that there should be an end amount or some value from in between... I just don't know. Please help?

In one day there are too high tides into low tides and equally spaced intervals the high tide is observed to be 6 feet above the average sea level after six hours passed a low tide occurs at 6 feet below the average sea level in this task you will model this occurrence using a trigonometric function by using x as a measurement of time assume the first high tide occurs at x=0. a. what are the independent and dependent variables? b. determine these key features of the function that models the tide: 1.amplitude 2.period 3.frequency 4.midline 5.vertical shift 6.phase shift c. create a trigonometric function that models the ocean tide for a period of 12 hours. d.what is the height of the tide after 93 hours?
