Asemi-truck has 18 tires. a bike has 2 tires. how many fewer tires does a bike have than semi-truck?

Multiply. write your answer in simplest form. 3/8 x 5/7

Me complete this proof! prove that a quadrilateral is a square. me with the steps for this proof.

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?
