Answer:
3/10
Step-by-step explanation:
3 red, 4 green, and 3 yellow balls = 10 balls
P(red) = number of red balls / total balls
= 3/10
8÷18=84÷y
8y=18×84
8y=1512
y=189
To find a speed in miles per hour, we need to divide a number of miles by a number of hours.
We are given 48 miles, so we already have a number of miles.
We are given the time as 1 hour and 12 minutes. We need to convert this time into hours.
1 hour + 12 minutes = 1 hour + 12/60 hour = 1.2 hours
speed = distance/time = 48 miles / 1.2 hours = 40 mph
Answer: The fourth choice, 40 mph.
3x³×y²×12x²×y×z=36x⁵×y³×z
