Urgent Answers Please! URGENT!

[Dingo_Dog]

Hi Guys, I need answers for the following Maths Questions, preferably before Saturday. Please. Extremely Urgent, and please answer them correctly.

And also more than 1 person answer (so all the answers can be confirmed.)

1. How many significant figures are there in 2800?

2. Simplify p/x + 3q/y (I couldn't find the fraction signal so...it should be read like "p over x + 3q over y)

3. Factorise 18 - 6m

4. Find sin35° correct to 4 decimal places.

5. Expand and simplify (m - n)(p - q)

That's all for now, more may come on the way. Please Help me Here.

Thank You all SF.

Try using google.com first. This maths isn't very hard to do. If you want it done by Saturday you have a few days. Try that before asking people to do it for you.

That's the thing, I don't have an internet connection at home. I rarely go to a internet cafe,

and please do trust me, I am trying, these are the ONLY questions that have got me stuck, there are many more maths questions, but I've done them all, these are the only ones that have got me stumped.

I don't have time for Google, if I did, then obviously I would look there first.

Thanks All.

3. 6(3-M)

4. sin(35 degrees) = 0.573576436
= 0.5736

5. = MP-MQ-NP+NQ
= 0

#2 answer. (p y+3 q x)/(x y)

This website should help you in the future.

The / means a fraction.

[daneasaur]

1. two (2 & 8)
3. 6(3-M)
We use 6 because it can fit into both 6(1 time) and 18(3 times). We then make the equation equal 18-6M. 6x3 = 18 , 6xM = 6M.
4. 0.573576436 = 0.5736
We round the 5 up to 6 because the next value is higher than 4. To find this value using calc.exe (microsoft in-built calculator), type '35' then press the sine key 'sin'.
5. MP-MQ-NP+NQ = 0
We know this because each value is cancelled out by another value.
