B. 6
Explanation: 8(6+4)= 80
38+ 7(6)= 80
Answer:
6 x 3 = 18 + 2 = 20/3
3/4 X 3/20 =
3 X 3
-------- = 9/80 already simplified to lowest
4 X 20
find total area by multiplying 350' x 200' = 70,00 sq ft
area of one block, multiply 25' x 25' = 625 sq ft = area for one Security guard
divide area for one security guard into total area of facility 70,000 / 625 =
112 security guards
find how many people for each block = 70,000 / 625 = 112 blocks
12,000 people divided by 112 blocks = 12,000 / 112 = 107.14 rounded to nearest 10 = 110 people per block
