T = 12 min, T o = 80° C, T s = 50 °C, T ( 12 ) = 60° C
60 = 50 + ( 80 - 50 ) · e^(-12k)
10 = 30 · e^(-12k)
e^(-12k) = 0.3333...
ln ( 0.333.. ) = - 12 k
- 12 k = - 1.1
k = ( - 1.1 ) : ( - 12 ) = 0.0916
Answer: D ) 0.0916
Answer:
100 feet apart
Step-by-step explanation:
Each line represents 40 feet. Ayla is 6 lines past 0 and Ahmad is 4 feet past 0. 6 times 10 is 60 and 4 times 10 is 40. 60+40=100 feet apart
The side with the larger spaces units are the inches and the side with the smaller spaced units are the centimeters
