Answer: D -10 - 12
Step-by-step explanation:
Temperature change is (Final T) - (Initial T)
(Final T) = -10C
(Initial T) = 12
(Final T) - (Initial T) = -10C - 12C
Temp Change - 22C
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 inches
After 2 hours height of candle=4-0.6-0.6 inches
after x hours height of candle=4-0.6x
Also,
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=4.166
Hence, equation to represent the situation. is:
4-0.6x=1.5
and the expected number of hours in which the candle melted to 1.5 inches is:
4.166 hours
