Answer:
20/56 or 5/14
Step-by-step explanation:
Prob of red = 5/8
Second red prob = 4/7
multiply those = 20/56
simplify if needed = 5/14
Let y and x be the numbers that varies directly (that means they keep the same proportion)
Then we have 7y = 3x, OR y/x =7/3 (this ratio should be kept for any value of x and y:
y/x = 7/3, if y = 28, then 28/x = 7/3 or x = (3)(28)/7 = 12
SO X = 12
Answer:
1263 seconds
Step-by-step explanation:
100 meters = 12.63 seconds
multiply both sides by 100 since
100*100= 10,000 meters
12.63*100= 1263 seconds
