Answer:
5 hours
Step-by-step explanation:
45 times 5 = 225
Answer:
(a)96.77%
(b)3.23%
Step-by-step explanation:
Starting with the Michaelis-Menten equation which is used to model biochemical reactions:
Dividing both sides by 
![\dfrac{v}{V_{max}}=\dfrac{[S]}{K_M + [S]}](https://tex.z-dn.net/?f=%5Cdfrac%7Bv%7D%7BV_%7Bmax%7D%7D%3D%5Cdfrac%7B%5BS%5D%7D%7BK_M%20%2B%20%5BS%5D%7D)
Where: 
maximum rate achieved by the system

The the equation K = C + 273.15 when solved for c is C = K - 273.15
<h3>Change of subject of formula</h3>
K = C + 273.15
- subtract 273.15 from both sides
K - 273.15 = C
Therefore,
C = K - 273.15
Complete question:
The temperature measured in Kelvin (K) is the temperature measured in Celsius (C) increased by 273.15. This can be modeled by the equation K = C + 273.15.
