Using a scale factor, how tall will the actual building be?
1 answer:
Answer:
OPTION C: 105 ft.
Step-by-step explanation:
Note that the width of the building in the map is 3 ft.
The width of the actual building is 45 ft.
That means, the actual building is 15 times more than the map, since, .
Therefore, the height of the actual building would be 7 X 15 = 105 ft.
Hence, the height of the actual building is 105 ft. which is OPTION C.

Step-by-step explanation:
For an equation to be dimensionally correct the dimension of quantities on both sides of equation must be same.
Also, two physically quantities can only be added or subtracted only when their dimension are same.
here all option are dimensionally correct except the 5th option where
dimension of t= [T] whereas dimension of a/v is
= T^{-1}
since, the dimension of quantities on either sides of equation are not the same the equation is dimensionally is incorrect.
