So we can use the following digits: 4,5,6,7,8,9
and we need three numbers with 8 digits each. Here are some examples:
1)
45 678 999 (you can also write 45,678,999 for easier reading)
2) 44 456 789 (you can also write 44,456,789 for easier reading)
3)45 678 456 (or 45,678,456)
Answer:
Both candles will have the same height after 4 hours.
Step-by-step explanation:
The equation for the amount of candle remaining can be given by the following equations:

In which Q(t) is the amount after t hours, Q(0) is the initial amount and a is how much it decreases, in inches, per hour.
Red candle:
8 inches tall and burns at a rate of 7 divided by 10 inch per hour. This means that
. So

Blue candle:
6 inches tall and burns at a rate of 1 divided by 5 inch per hour. This means that
. So

After how many hours will both candles be the same height ?
This is t when


![0.2t - 0.7t = 6 - 8[/yrc][tex]-0.5t = -2](https://tex.z-dn.net/?f=0.2t%20-%200.7t%20%3D%206%20-%208%5B%2Fyrc%5D%3C%2Fp%3E%3Cp%3E%5Btex%5D-0.5t%20%3D%20-2)
Multiplying by (-1)



Both candles will have the same height after 4 hours.
31.5 times 1.8.
=31.5×.8+31.5×1
=25.2+31.5
=56.7
