The disk outer track is the 0track and the disk contain 200tracks per surface .Each track hold eight sectors numbered 0through 7

i used to know but i learned it a long time ago sorry

step-by-step explanation:

since proposition states that a number is greater than 25, if is true then the number must actually be greater than 25.

this implies that all possible options, except 24, can be accepted

i think the answer is 90 hope this

you estimate that the angle of elevation to the top of the 86th floor (the observatory) is 82 .the total height of the building is another 123 meters above the 86th floor.

leave feedback if u need : )
