You don't have to give me the answer, if you can just write out what you need to do, i would be greatly appreciated.

Five times the complement of an angle less twice the angle's supplement. Find the measure of the supplement.

For example, if a wheel is spinning, is it possible for the direction in which it is spinning to be reversed without ever stopping for a moment?

If so, how?

Is not, why?

In healthy adults the average pH of spinal fluid is 7.39
From a sample of unhealthy 44 patients with the mean spinal fluid was 7.26 with a standard deviation of 0.17. Can we conclude, at the 0.5 level of significance, that the pH of unhealthy patients is different from the pH for healthy patients? Explain.

If a plane has to dump fuel, from a height of 125m, before landing to avoid a firey crash, How long would it take to for the fuel to fall to the ground?
Im stuck at :
125=0(t) + [(9.8)(t)^2 (1/2)]

I know that I can take out the 0t because it will equal zero not matter what t is. Im having a slight problem with the algebra.

G, H, and I (ramdom variables) belong to a family of very active metals, all of which react with chlorine to produce salts with the general form XCl. G is a member of the first period to contain 18 elements. H has the highest ionization energy of the group and I has the lowest. What are the elements representing G, H, and I?
