Ted practices two types of swimming styles for a total of 50 minutes every day. He spends 20 minutes more practicing the breast stroke than the butterfly stroke.
Part A: Write a pair of linear equations to show the relationship between the number of minutes Ted
practices the butterfly stroke every day (x) and the number of minutes he practices the breast stroke
every day (y). (5 points)
Part B: How much time does Ted spend on practicing the breast stroke every day? (3 points)
Part C: Is it possible for Ted to have spent 45 minutes practicing the butterfly stroke every day?
Explain your reasoning. (2 points)

Aman is 6 feet 3 inches tall. the top of his shadow touches a fire hydrant that is 13 feet 6 inches away. what is the angle of elevation from the base of the fire hydrant to the top of the man's head?

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?
