Q:Do products like STP work?

if you are using a top quality gasoline like shell, it already has those additives in it. if you are not using a good quality gas (generic brands) they won't have as many or as good of additives and a periodic additive can help. yes, you can clean the injectors to a degree with an additive. i don't live close to a shell station (i get easily my best gas mileage on shell gas) so i periodically add a cleaner and it will affect the fuel economy. as for 'dry gas', there was a reason for that, but it's gone now, so it's a waste of time. the reason was that gas can get water in it and the dry gas bonds with it allowing it to be burned and keeping it from freezing in the winter. but all that was is alcohol, now that ethanol is in all gasoline, it's unnecessary.

Q:Black Female artist of 2003 or 2004

I wish I could catch one of the idiots sticking one on my car. I hate them, but these guys are real sneaks! I do make a show of removing it, destroying it and properly disposing of it.

Q:what law? when did it pass? and what changes to this law have been made?what was the most popular additve to gas and why?is it still being uesed and why?what %of dem voted for it ? what %of gop voted for it?

Hey Bro, Here is a link to help you find what you need to know. www.epa /otaq/fuels.htm Basically the additives are added in the winter to reduce carbon monoxide. Some states use ethonol, others use MTBE(which is being phased out)

Q:I need to find the inverse of -2x + 3y – 4z and put it in simplified possible form?

additive inverse is that number with which you add the original number and get zero so the additive inverse of this number is -(-2x+3y-4z) 2x-3y+4z when you add this additive inverse with the original number provided in the question you get zero

Q:I am the person with the 1994 toyot pick up that has (had) heating problems.I found out what the problem was.The shop that I let replace the radiator, sold me/ installed a POS "cheapy" radiator.I found a significant leak / separated weld around the tops inlet.They replaced the POS radiator with a CFS radiator.It is obvious (by simply looking at it) that this radiator is a MUCH BETTER built radiator.I would still like it to run a little cooler.Does anybody know of anyone that has ever used a coolant additive? Do they really make a dofference? I am planning on running water wetter with a 25-30 to 70-75 mixture of anti-freeze to water, and then add water wetter?Does anybody know if this will make a significant difference driving across AZ and NM during the end of october?

Whoa! Use the recommendations of the coolant manufacturers, and you don't need to use additives with new coolant! There are no additives that will make it run significantly cooler, anyway, unless you are running straight water in your rad, which is stupid for a road vehicle. Additives are to re-inforce the ingredients in coolant that fight rust, etc. The only practical way is to increase airflow across the radiator, but then the engine may never reach optimum operating temperature, meaning it will use more fuel. Water wetter is said to reduce operating temperatures by 30 degrees, but read the information properly - IN SYSTEMS NOT USING COOLANT, in racing engines, and in systems with signicantly smaller cooling systems, or systems where people are too damn lazy to change their coolant often enough! A 50-50 water-to-coolant mixture is standard, as it offers protection against the maximum temperature ranges most of us will experience. 50% anti-freeze is also the recommended minimum for corrosion protection, 70% is the maximum concentration recommended, stronger and the stuff can start to gel and restrict the ability of the mixture to transfer heat. Between 50 and 70% the cooling at high temperatures is not changed much, the difference is cold protection, and the higher concentrations would be for areas like Alaska and the Yukon.

Q:can anybody explain what a additive inverse is? i mean as in math wise, like property.also, is 6+(-6)0 a additive inverse or additive identity?

It would be very dangerous to sleep with your electric blanket in a bathtub, for sure.

Q:seven and a bracket.

I'm not sure if I understand. You may want to type it using the symbols instead of the words. I'll try it. -a[a-a7] -a[a-7a] -a[-6a] 6a^2 The additive inverse (or opposite) is -6a^2

Q:On the bottle it says Add 4 fluid ounces to treat 1 full gallon of plain water or washer fluid in washer tank. What does this mean? Do I put a gallon of water in my windshield washer reservoir and only 4 ounces of the rain-x?

Pipe that have not burst yet will not burst later but all the joints could be damaged enough to leak very slowly and separate later. I agree with all pipe joints must be repaired and re-soldered. Consider how much damage one leaky pipe in a wall might do after you have the house all fixed up. I do not think it is worth the risk.

Q:Helping lubricate valves, high mileage engines, increasing compression.all of the claims on the labels, are they true? Better yet, are they worth the money?

the only oil additive i know of that is worth the money is Lucas oil stabilizer. I have used it in my semi truck and in all my rear end gearboxes. I use Mobil 1 in my crankcase so i dont use it in the oil but if you are using a conventionl oil then it cant hurt, expecailly on an older engine.

Q:1) additive inverse of. -7a +3b2) write using positive exponents. x^-5y^2z^-3 ^ means exponent. thank yooou!

I've forgotten how to do the additive inverse, but I do remember how to do positive exponents. example x ^ -1 is the same as 1/x x ^ -10 is the same as 1/(x ^ 10) I remember this by associating the negative sign with 1 over.
