8. A candle is 4 inches tall and burns at the rate of 0.6 inch per hour. If the height of the candle after x hours is 1.5 inches,write an equation to represent the situation. Then use this equation to find the expected number of hours in which the candlemelted to 1.5 inches.
Accepted Solution
A:
Answer with Step-by-step explanation:A candle is 4 inches tall and burns at the rate of 0.6 inch per hour.i.e. after 1 hour height of candle=4-0.6 inchesAfter 2 hours height of candle=4-0.6-0.6 inchesafter x hours height of candle=4-0.6xAlso, If the height of the candle after x hours is 1.5 inches⇒ 4-0.6x=1.5⇒ 0.6x=4-1.5⇒ 0.6x=2.5⇒ x=2.5/0.6⇒ x=4.166Hence, equation to represent the situation. is:4-0.6x=1.5and the expected number of hours in which the candle melted to 1.5 inches is:4.166 hours
