An ancient Chinese candle clock tells the amount of time that has passed by the amount of wax that has been melted off the candl

e. Each candle is divided into 12 sections, marked 1 inch apart. It takes 4 hours for each candle to completely melt, after which a new candle is lit. If two candles have completely melted and one candle has melted 4 in, how many minutes have passed since the first candle was lit?

Two candles=8 hours=8*60=480 minutes
4 inch is 4/12 of a candle, 4/12 of 4 hours=16/12=4/3 hours=80 minutes
so the total minutes are 480+80=560

Answer:

480+80=560

If a colored candle and a white candle are burned at the same time for an hour, then the colored candle will burn faster, because it has more chemicals than the white candle.

A rope is 66 feet long. It is cut into two pieces such that one piece is half the length of the other. What is the length of the
dedylja [7]
So if one bit of the length, is half the size of the other bit then we can make the following equation, for x being the length of rope:

x + 2x = 66
3x = 66
x = 22

That is the length, of the smaller one (half the big one), so 2x = 44. Hence d) is your answer.

Hope I helped!

qaws [65]

Answer:

Step-by-step explanation:

For each of the yp(x) we can deduce the characteristic polynomial of the differential equation

A.

yp(x)=Ax^2+Bx+C\\m^2=0\\y''=0

B.

yp(x)=Ae^{2x}\\(m-2)m=0\\m^2-2m=0\\y''-2y=0

C.

yp(x)=Acos2x+Bsin2x\\m_1=2i\\m_2=-2i\\y''+4=0

D.

yp(x)=(Ax+B)cos2x+(Cx+D)sin2x\\yp(x)=xcos4x

hope this helps!!
