Answer:
9 p.m.
Step-by-step explanation:
Lowest common multiple (LCM) of 6 and 4.
LCM of 6, 4 = 2 × 2 × 3 = 12
After 12 hours 9 A.M. = 9 P.M.
After 12 hours at 9 P.M. she will take both medicines together again.
Answer:
Step-by-step explanation:
The max value that this function reaches is 6, and the function reaches this value repeatedly, beginning at x = 0 and then at x = 6, 12, 15, etc. This tells us that the period of the function is 6.
The function is increasing on (3, 6), (9, 12), and so on
The function is even because the graph is symmetrical about the y-axis.
He spent exactly 20.25, so it's A.
The answer is D. 12
4, 3 and 2 are all factors of 12 (least common denominator)
