If you show me, you can win xP Because you got everything correct except 4, which... Well... Volume is four thirds multiplied by pi multiplied by r cubed. xDDDD Can you solve that aswell? xPP
Check question 4 again, for number 1, find a caculator with brackets, not google caculator. You will find that numbers before the bracket have higher priority.
Alright, I did solve all of these, but I won't post them since xdras fot them all already. (Falcon pride brah) For question 1, it was correct. If you expand it properly with BODMAS, then xdras' answer is correct. Try it with a scientific calculator. What larrythebird101 did was to do the division symbol first, before doing or expanding the brackets, I believe that xdras' method was correct. As for question 4, no matter how many times I try, I get the same answer as xdras, possibly a human error on your part. Nonetheless, this giveaway is done in a really creative method~! Good job coming up with such an idea. :3 Question 1 Explained: Alright, so...this is how question 1 should look like in fractional form: {2.75} / {26.3(257^2-10/3)} Then, you expand the brackets, which should give you: {2.75} / {26.3 × 66045.667} From here, you simply simplify the fraction down to: {2.75} / {1737001.033} Finally, complete the fraction by solving it, which should give you: 0.00000158318
Actually, I did number one on paper. No, they don't have higher priority; it's PEMDAS. Par I don't understand xD I did the math multiple times and got a totally different answer So... Confusion
Yes, you did number one on paper, please use any high tech (scientific) calculator to check your answer, you will find the answer. Also try not using 22/7 or 3.14 use a much larger digit of pi that should give you a more accurate answer.
IGN Awesomeness12312 Problem 3: Solve for the variable. 23y+13=174 174-13=161 161\23=7 y=7 Problem 5: What is twenty-seven over thirteen as a percent? 27/13= 207.6923 Problem 2: Simplify. 12.36(23y+26a)=30a+3y 284.28y + 321.36a = 30a +3y 281.28y + 321.36a = 30a 281.28y+ 10.712a=a 281.28y=-9.712a
I'm not in school. Can you not throw mathematical equations at me? LOL jk. I can solve these it's just that I'm too lazy
Also, I did use a calculator. And I used PEMDAS, as it said to use in the beginning. Sorry, but I'm afraid I don't quite understand what you're trying to say. I did the parenthesis, then I did exponents, then I did multiplication and division, then I did addition and subtraction. What other answer can you get when you do this? I wrote it down on a word document and I did the long division and multiplication problems with a calculator.
Hmm...I'm fascinated by this discussion...could you explain the flaws in this for me? (Learning new things are always good~)
Look at a scientific calculator, you will find that numbers before a bracket have a slightly lower priority than numbers in the bracket. but before the multi and division in order. look at this. btw by adding more digits on pi the number will only get bigger, the answer is 321.56 because 5 is rounded up
