Answer:
1152
Step-by-step explanation:
4 boys and 4 girls be arranged in a row such that no two boys and no two girls are next to each other.
Two boys and two girls are not next to each other. so one boy and one girl are next to each other in two ways.
BGBGBGBG, GBGBGBGB
4 boys are arranged in 4! ways and 4 girls are arranged in 4! ways
So number of ways = 
X+y=8
multiply the first equation by 3 to get rid of x
3x+3y=24
3x+2y=14
subtract equation 1 from 2
y=10
substitute to find the value of x
x+10=8
x=-2

Answer:
Scale of 181: 1
Step-by-step explanation:
The first thing to do is to pass the feet by the meter, to work in the same units and thus create a consistent scale:
We know that one foot equals 0.3048 meters, therefore:
8 feet * 0.3048 meters / 1 foot = 2.4384 meters
So the scale would be:
443.2 / 2.4384 = 181.75
Which means that it is best to make a scale of 181: 1
Where 181 meters from the Empire State Building would equal 1 meter at home 0 181 inches would equal 1 inch at home
