Dang, I see where I messed up. Thank you so much.

whoops, sorry everyone. The original message was supposed to be a reply to another post.

Because when you multiply or divide any number (a positive or a negative number) by a negative number you will automatically change the sign of the number you are performing the operation on. In an inequality you will then reverse the relationship between the numbers on each side of the inequality. Use some examples like: 2 less than 3 divided by -1 and you will see that the answer is -2 is greater than -3. The equality of an equation is never changed if you perform the same operation on each side of the equation. Example: 2 + 2 = 4. If you add, subtract, multiply or divide each side of the equation by the same number the result will be an equality. Keep in mind that addition and multiplication are the only operations and that subtraction and division are only reverse addition and multiplication.

Thank you Ms Sue.

Thank you very much. The answer doesn't change, but my trig teacher wants to see all of work, and I just wasn't sure which figure to use.

A line graph with a solid dot at -4, a solid dot at 10, and shading between the two. o--------------------o -4 0 10 where the 0 are solid or you could use a [ at -4 and a ] at 10 [----------------------] -4 0 10 I think that is how interval notation works, but I could be wrong.

well my spacing for -4, 0, 10 didn't come out right, but hopefully you get the idea. -4 at the beginning, 0 towards the middle, and 10 and the end.

I found my mistake, please disregard.

So far i have not compleatly worked it out.but compound E is NOT NH3. it is NH2OH, which you can tell only by its titation information. compound D is N2O2H4 in some order. compound A is likely Nitric Acid.

Dont know the first one Broken character i'll get over it

One equation would be: x+y=69, correct? (add two integers to equal 69). But then we know the integers are consecutive, so the second integer (y) is one greater than the first interger (x). So the next number after x is x+1 So we can say y=x+1 Then follow the train: x+y=69 x+(x+1) = 69 x+x+1 = 69 x+x = 68 x=34 Perhaps you can use the above to determine which equation from your choices would work.

One possible answer is Marty's pizza was much larger than Luis' pizza.

Some information is missing. The engine has 1 1/4 gallons of oil in it now? And the question is how much more oil is needed to fill to capacity (full). What is the capacity of oil in the engine?

In order to ride the roller coaster, you must be 48" tall, so H=48. If the question is you must be at least 48" tall, then H=> (equal to or greater than) 48" tall.

h<48 is not correct, since since this says the height (h) is less than 48" (ie too short).

Liquid elemental iron is produced in the thermite reaction because enough heat is generated to melt the iron: 2 Al(s) + Fe2O3(s)----> Al2O3(s) + 2 Fe(l) What mass of aluminum is needed to produce 750 grams of iron?

What is the pH of a buffer solution that is made by adding 21.0 grams of sodium fluoride to 1.00 Liter of 0.15M hydrofluoric acid? (see the Table above for the Ka of hydrofluoric acid; calculate the pH to 2 decimal places) hint: you will have to find the molarity of NaF in this solution. Acid Dissociation Constant: HF 6.6 x 10-4

Sorry about the Chinese, the Chinese words are Celsius.

Also, what is a structure (with the same function as the one above) that was built with no regard to cost: What are the difference between the two?

Thanks Ms. Sue!

Thank you for responding! Is #1 D instead?

The prime factorization for 66: Prime factorization is writing a composite number as a product of its prime factors. Sample A: The prime factorization of 504 is 2^3 x 3^2 x 7. In other words, it is a way of writing a product the long way. Sample B: The prime factorization of 30 is 2 x 3 x 5. Your question: The Prime Factorization of 66. What is the biggest number that goes into 66 without a remainder? How about 11? 11 x 6 = 66, right? We cannot break down 11 anymore but it is one of our composite numbers that we used as a factor of 66. What about 6? What are the factors of 6? How about 2 and 3? Yes, 2 x 3 = 6. We cannot break down 2 and 3 anymore. Final answer: The prime factorization of 66 is: 2 x 3 x 11. That's it! Prime factorization of 99 is: To learn the prime factors of 99, find two numbers that multiply together to make 99, such as 9 and 11. Eleven is a prime factor because it is only divisible by itself and 1, but 9 is not prime. Next, find two numbers that multiply together to make 9, such as 3 times 3. Since 3 is prime, all the prime factors have been found. Answer : 22 • 5. 20 is NOT a prime number. I don't have enough room to work out 108, 37 and 450.

Where is the Statue of Liberty? It's in New York, you seriously didn't know that? LOL! Wow. Ha-ha.

What's that supposed to mean? I didn't do anything.

Just like what Reiny said, just try and expand it yourself. See what you can find! :)

It looks great! I don't think you need any changes. Is this a writing assignment you did yourself? If it is, it's very strong!

There has been so much said, and on the whole so well said, that I shall not occupy the time.

In other words, refer to the answers above and perhaps to others on the internet. You're welcome!

I want more clarification of the answer!
