Answer:575 and 1 extra tile
Step-by-step explanation:if the total tiles is 5,176 which will be used in 9 floors .We will divide the total tiles by the floors .Therefore we will get 5176 /9 =575.111
Therefore each floor will have 575 tiles
To get the remaining tiles
575*9 = 5175 which gives us a remainder of 1 tile when you subtract the total 5176 -5175 =1
Perpendicular lines have negative reciprocal slopes. So if the slope is -2/5...to find the negative reciprocal, " flip " the slope and change the sign.
So we flip -2/5 and we get 5/-2...and now we change the sign...and we get 5/2. So our perpendicular slope will be 5/2.
Answer: -5x
