Answer: 3:18
Step-by-step explanation: multiply the ratio and then 3 ft.
It is given that at a local fair, a roller coaster takes 19.63 seconds to complete one ride
six people can ride at the same time
one hour=60 minute
1 minute= 60 second
therefore, one hour = 3600 sec
therefor no of people who can ride the roller coaster in one hour=3600*6/19.63=1100 people
therefore 1100 is the answer
3x²<span> + 2x + 7 = 0
D = b</span>² - 4ac = 2² - 4*3*7 = 4 - 84 = -80
D < 0 ⇒ <span>No real solutions</span>
Answer:
x = 13/3
Step-by-step explanation:
12(x - 1) = 40
Distribute
12x -12 = 40
Add 12 to each side
12x -12+12 =40+12
12x = 52
Divid each side by 12
12x/12 =52/12
x = 13/3
