Ming made a triangular picture frame out of cardboard. The sides of the frame are 6.75 in., 6.75 in., and 8.375 in. Ming uses th
e addition below to determine the amount of string she needs to decorate the edges of the frame. mc012-1.jpg Which explains Ming’s error? She should have included the decimal in 6.75 and aligned the decimal points to add 6.750 + 6.750 + 8.375 = 21.875. She forgot to put the decimal point in two of the numbers: 0.675 + 0.675 + 8.375 = 9.725.. She added 6.75 twice, and she should have only added it once: 6.75 + 8.375 = 15.125. She should have placed a zero placeholder after the decimal point to add 6.075 + 6.075 + 8.375 = 20.525.
the memory is the independent, because that can vary at will, so it's independently varying at will, whilst the amount of songs are limited to how much memory there's in the CD, so the songs are dependent on the memory availability.
