Answer:
BC = 6
Step-by-step explanation:
Using the sine ratio in the right triangle and exact value
sin30° =
sin30° = = = = ( cross- multiply )
2x = 12 ( divide both sides by 2 )
x = 6
That is BC = 6
This is an equation involving x alone, so the most you can do is solve it:
32 days
Assume that the jar is full initially, containing 24 oz. After how many withdrawals of 3/4 oz will the jar be empty?
24 - (3/4)n = 0, or
24 = (3/4)n, or 96 = 3n. Dividing both sides by 3, we get n = 32.
The jar will be empty after 32 days.

150 - 42 = 108
108 ÷ 6 = 18
therefore m = 18
hope this helps...
