Answer:
3.6 minutes.
Step-by-step explanation:
According to the data given in the question, between 9 and 10 AM, 220 passengers have checked in which means that the check-in rate is 3.6 passengers per minute. If the average number of passengers waiting for check-in is 32 and if we assume that the check-in rate is constant throughout the day, then the average passenger had to wait in line for 3.6 minutes.
Answer:
4:1
Step-by-step explanation:
x+20 : y+20 = 5 : 2
(x+20)/(y+20) = 5/2
2(x+20) = 5(y+20)
2x+40 = 5y+100
2x = 5y+60 (1)
x-5 : y-5 = 5:1
(x-5)/(y-5) = 5/1
x-5 = 5(y-5)
x-5 = 5y-25
x = 5y-20 (2)
Solve (1) & (2) simultaneously,
2(5y-20) = 5y+60
10y-40 = 5y+60
5y = 100
y = 20
x = 5y-20
x = 5(20)-20 = 100-20
x = 80
x:y
80:20
4:1
Let x be the size of the small room and 2x, the big room
The larger room requires 3 coats and the smaller, 2 coats
All requires exactly 8 gal.
2.x + (2x).3 = 8 Gal, 8x = 8 and x = 1 (size of te smallest)
if it's the small room, then it will need 2 coats or 2x1 = 2 Gal, and the paint left is 8-2 = 6 Gal.
if it's the large one, 6x or 6 Gal, and remaining 2 Gal
Try drawing a scale chart and on one side theres 100 and same on the orhter
