Error analysis- MULTIPLY AND DIVIDE DECIMALS Zoey made a shelf to store her collection of dolls. she used 5 pieces of wood that were 2.15 feet long. how much wood did Zoey use in all to make the shelf?
2.15x5=1075
Zoey used 1,075 feet of wood to make shelves.
identify and explain the error.
show the correct work By an image or do anything to show it
share a strategy. :)
Also if u do all this you'll get brain!!! <3

Franco wants to double the volume of the cone. what should he do?

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?

Combine like terms to create an equivalent expression. make sure to simplify coefficients and constants as well. -6/5-2/3v+4/15+1/3v
