Answer:
11 3/7 hours
Step-by-step explanation:
The shorter candle burns faster, so the candles will not be the same height (0) until the taller candle burns completely. At 0.7 in/h, that will take ...
(8 in)/(0.7 in/h) = 80/7 h = 11 3/7 h
the correct answer is negative
Jus combine like terms. Treat pi like a variable.
x - 8pi = pi
Combine like terms by adding 8pi to both sides to get
x = 9pi
Answer:
31
Step-by-step explanation:
if sin(x) = cos(y)
then x + y = 90
.
in this case X + 59 = 90 : X = 31
