Answer:
They made 2 batches
Step-by-step explanation:
If the factory used ⅔, and 1 batch is ⅓, the factory made 1 batch for each 3rd they used. ⅔, 2 batches
probability of drawing ace: 4/52 = 1/13
probability of drawing 9: 4/52 = 1/13
probability of drawing ace or 9: 1/13 + 1/13 = 2/13 or ~15.4%
Building time :
4c + 6a < = 120
testing time :
4c + 4a < = 100
20 child bikes and 6 adult bikes...c = 20 and a = 6
sub into both equations
4c + 6a < = 120
4(20) + 6(6) < = 120
80 + 36 < = 120
116 < = 120 (correct)
4c + 4a < = 100
4(20) + 4(6) < = 100
80 + 24 < = 100
104 < = 100 (incorrect)
ur answer : No, because the bike order does not meet the restrictions of 4c + 6a < = 120 and 4c + 4a < = 100
Answer:
2/7 = 4/14
3:3 = 6:6
1/2 = 2/4
2.5:6 = 5:12
Step-by-step explanation:
For the first one, we can multiply the numerator and denominator of the fraction by 2 to get an equivalent fraction which is 4/14
For the second one we can multiply each side by 2 to get the ratio of 6:6
For the third one we can multiply the numerator and denominator by 2 to get 2/4
For the last one we can multiply each side by 2 to get 5:12
