Answer:

The temperature of the chemical solution after t hours is -14.96-2.9t\;^{\circ}C

Step-by-step explanation:

Given that the initial temperature of the chemical solution, T_0= -14.96^{\circ}C.

The rate of decreasing temperature, R = 2.9^{\circ}C/ hour

So, after t hours, the temperature of the chemical solution will decrease by Rt=2.9t^{\circ}C.

So, the temperature of the chemical solution after t hours,

T=T_0-Rt \\\\\Rightarrow T = -14.96-2.9t\;^{\circ}C

Hence, the temperature of the chemical solution after t hours is -14.96-2.9t^{\circ}C.

ValentinkaMS [17]
The number will be itself when multiplied by 1.

The sum of twice and half the original number is 1, so the number is
  2n +0.5n = 1
  2.5n = 1
  n = 1/2.5 = 0.4

The original number is 2/5.
