Answer:
Because the kind of compounfds that you try to determine using paper chromatography (organic compounds) are usually not soluble in water. Furthermore, water could react chemically with some of this compounds, because it's a very reactive molecule. You need organic solvents that are mostly inert.
You could use so many for example 4, 10, 57, 5729, any number above 4 would work since that plus 8 would be greater than 11
Answer:
357.50$
Step-by-step explanation:
550 x 35% =192.50$
550 - 192.50 = 357.50$
Pretty sure its 3 chapters an hour
Becouse if she reads 3 chapters per hours it will be 3 X 6=18
In getting the x, you must first convert the said data in to a slope intercept form and the formula for it is y = mx+b so the slope is 7/16 while the y is 3.5. In that data its self you can came up with the equation of 3.5 = 7/16x + 0 and the value of X would be 8. I hope you are satisfied with my answer
