Answer:

Temperature after 10 minute = 27.9 degree Celsius

Step-by-step explanation:

Current temperature, P = 100 degree Celsius

% rate in temperature loses = 12% per minute = 0.12

Time, t = 10 minutes

Temperature after t minutes ,

$= P ( 1 - r )^t\\\\=100( 1 - 0.12)^10\\\\=100(0.278500976)\\\\=27.85$

= 27.9 degree Celsius

9/2h = -1 what does h equal too?

Sergeeva-Olga [200]

$\textbf {The answer is h = -2/9.}$

$\textrm {We are given that 9/2h = -1. Hence, divide by 9/2 on both sides.}$

$\frac{9/2h}{9/2} = \frac{-1}{9/2}$

$\boxed {h = -\frac{2}{9}}$
