Step-by-step explanation:
Hello answer is "n is more than 9" !
The first step is to find the relationship between the square base and the surface area.
Surface area (SA) = area of the square (SS) + area of triangles.4(AT)
Thus we can conclude area of triangles 4(AT) = SA - SS = 864 - (18*18)
4(AT) = 864 - 324 = 540
Each triangle = 540/4 = 135 square in.
An area of one triangle (AT)= (base* slant height)/2
The base = 18 in.
<span>slant height = 2(AT)/base = 2(135)/18 = 15</span>
Answer:
360 people in 3 hours. 120 people per hour.
Step-by-step explanation:
How many times do 20 minutes go into 3 hours?
Well, 60 min. ÷ 20 min. = 3
So, 3 x 3 = 9
So 40 people went on the ride each 20 minutes. And there are (3) 20 minutes in every hour.
So 3 hours would be 9 x 40 = 360
120 people per hour because 40 x 3 = 120
and 20 minutes (3) times equals 1 hour.
