Answer:
342.85714 %
Step-by-step explanation:
Percentage increase is given by
increase= (new - original)/ original * 100 %
The new is 186 and the original is 42
= (186 - 42)/ 42 * 100 %
=144/42* 100 %
=3.42857 * 100%
=342.85714 %

The answer to the question is C
Answer:
105 ft
Step-by-step explanation:
In this case, the first thing is to calculate the scale, therefore, we must divide the real measurement by the model measurement, like this:
45 ft / 3 ft = 15
Which means that the scale is 15.
Now, to calculate the height, we must multiply the height of the model by the scale, that is:
7 ft * 15 = 105 ft
which means that the height of the building is 105 ft
