Easy, soh cah toa
cos=adjacent dividd by hypotnuse
tan=oposite divided by adjacent
so cos A=addjacent side divded by hypotnuse=27/45=3/5
tan Z=16/30=8/15
The beginning has 12 seconds, the middle part has 36 and the end has 72 seconds.
Let’s separate the song into three parts and write and equation that equals to 120 seconds.
120= x + 3x + 6x
120= 10x
X=12 seconds
Answer:
that could be 1/3
Step-by-step explanation:
i simplified the answer
we know that
the car gets 18 miles per -----------> 1 gallon of gasoline
so
for 543 miles ---------------------> x gallons of gasoline
by proportion
543/18=x/1---------->x=543/18------->x=30.17 gallons
therefore
the answer is
30.17 gallons
