Q:

An artist completed an ice sculpture when the temperature was -10c the equation t=1.25h-10 shows the temperature h houses after the sculptures completion if the artist completed the sculpture at 8:00 a.m at what time will it begin to melt

Accepted Solution

A:
Answer:At 12 p.m in the mid night the sculpture will start to melt.Step-by-step explanation:The ice sculpture made at 8:00 a.m when the temperature was -10°c. At temperature 0°c the sculpture will start to melt, so there is a difference of 10°c. Now, the equation t =1.25h -10 gives the relation between the increase in temperature(t) with the number of hours(h) spent. So, for t=10°, we have, 10 = 1.25h -10 ⇒1.25 h=20 ⇒ h= 16 hours. So, the sculpture will take 16 hours to start melting. Therefore, at 12 p.m at midnight, the sculpture will start to melt. (Answer)
