Quantity name Water adds Final acidity of water
Unit Gallons Percent expressed as a decimal
Expression g (0.052*310)/(310+g)
Question 1 59.4 (I need this answer)
Question 2 (I need this answer) 0.041
I need help
Not sure what the question is asking.
Explanations would definitely help.
(0.052*310)/(310+g)=59.4
I have done it with all of these answers -310=g & 310=g &309.7286 &-309.7286 &-459947/1485 & 459947/1485 & -1541357/5000 & 59452 & 04386 & 309 & 309.73 &-309.73 & -310 & -310.729 & 5.94 & 59452
I did figure out the answer to question 2 I sill had to turn in all my work without this answer any help you can offer I will appreciate it very much.
309.72862 is correct.
This is how you could approach it:
Start with:
(0.052*310)/(310+g)=59.4
cross multiply to get
(0.052*310)=59.4 (310+g)
Expand and evaluate:
16.12=59.4g+18414
transpose
59.4g = 18414-16.12
g=(18397.88/59.4)
=309.72862
as you had it.
It sill says it is wrong, I have no clue.
i have done it with mathway a website and the center for math excellence
I looked over the possible answers, and 310 is among them.
If you are in a chemistry or physics class, or if you have already worked on significant digits, 310 would be the correct answer to 3 significant digits, since the original data are all to that accuracy.
Sorry that I didn't realize that those were given choices.
Thank you ill see what my professor has to say something doesn't seem right because more than one person has told me that same answer thank you for your all time.
After reading your response, I rechecked and surely I found the culprit: me.
I have the wrong sign!
The correct solution should have read:
This is how you could approach it:
Start with:
(0.052*310)/(310+g)=59.4
cross multiply to get
(0.052*310)=59.4 (310+g)
Expand and evaluate:
16.12=59.4g+18414
transpose
59.4g = -18414+16.12
g=(-18397.88/59.4)
=-309.72862
