I just completed a lab called "Acid-Catalyzed Dehydration of an Alcohol: Synthesis of 2-Octenes." I started with 2-octanol and the lab instructions said the product had the possibility of being 1-octene, trans-2-octene, and/or cis-2-octene. I did end up with trans-2-...

N=2.1t^2- 82t+95 Since N = 15, 15=2.1t^2- 82t+95 Now get this quadratic into standard form by subtracting 15 from both sides 15-15= 2.1t^2- 82t+95-15 0=2.1t^2- 82t+80 I am not sure what methods you have studied to solve this yet, but I would use the quadratic equation. Where a...

This would be a proportion. If 5 out of 8 WANT the program, then 3 out of 8 don’t So 3 is to 8 as what is to 10,000? 3/8= x/10000 Multiply both sides by 10000 10000 • 3/8= x/10000 •10000 30000/8= x 3750 = x
