Answer:
B. F:S = 17 to 19; S:F = 19 to 17
Step-by-step explanation:
Put the corresponding numbers in the corresponding parts of the ratio you want to write:
freshmen to sophomores (F:S)
17 to 19
___
sophomores to freshmen (S:F)
19 to 17
These pairs of numbers match choice B.
One minute later at 8:01pm. One lighthouse will flash 3 times (at 20, 40 and 60 seconds)...the other will flash twice (at 30 and 60 seconds). So they will both flash 60 seconds later, at 8:01
18*3 = 54
20*3 = 60
so the scale drawing would be 54cm x 60cm
