Answer:

C : 1,455 ft

Step-by-step explanation:

We know that the model is 19 2/5 inches

so to find the actual height you would simply

multiply by 75 to get your answer in feet.

To make it simple, 19 2/5 = 19.4

19.4 x 75 = 1455

The actual height of the skyscraper is 1455ft.

number of +ve integer divisible by 2&7&3 less than or equal to 210=e=210/42=5

<span>number of positive integers not larger than 210 and divisible by 2, 3 or 7=105+70+30-(35+15+10)+5

=150

so numbers not divisible=total-150
                                         =210-150
