temperature at 9:00 am was -24.25°C, what was the temperature at midnight?

Answer 1

Answer:-13

Step-by-step explanation:when you take the sides and they go with the polagrythem theory a2+b2=c2 then -13 with sho2.

Answer 2

-13°C

Explanation:

The number of hours from midnight to 9:00 am is 9 hours.

If the temperature dropped 1.25°C each hour then:

`\begin{aligned}\implies \textsf{Total degrees temperature dropped}& = \sf Number\; of \;hours * rate\\&=\sf 9\;h * 1.25^(\circ)C/h\\&=\sf 11.25^(\circ)C\end{aligned}`

If the temperature at 9:00 am was -24.25°C then:

`\begin{aligned}\implies \textsf{Temperature at midnight}& = \textsf{Temperature at 9:00 am}+\textsf{Total degrees dropped}\\&=\sf -24.25^(\circ)C+11.25^(\circ)C\\&=\sf -13^(\circ)C\end{aligned}`

Therefore, the temperature at midnight was -13°C.
