The octane rating of a gasoline is a measure of the amount of isooctane in the gas. Manufacturers recommend using 93-octane gasoline on returned motors. How much 87-octane gas and 95 octane gas should Yousef mix in order to make 10 gal of 93 octane gas for his returned Ford F-150?
Hello again, I would like to know how to figure out how to make the equation, then solve
Hey! We have t make 93 octane and 10 gallons. so our total amount will be 0.93*10.
Moving along: total gallons will be 10. so 0.95(10-x) Final equation: 0.87x + 0.95(10-x) = 0.93*10
There's one more method too if this looks hard to you. Let me know if this is hard to understand.
This method looked a bit more difficult than the latter, do you have an easier method?
x + y = 10 87x + 95y = 93*10
I see, I was trying to figure out how you know what goes where?
Haha. I don't know. I should ask that from my brain! :D
You are funny! Thank you! I have so much homework to catch up on!I am behind quite a bit, the class is already on Matrices and also sqrt[?]{?}.... I am VERY behind!
Lol. You're welcome. Oh! Matrices can be boring. Square roots are fun!
I don't know why but my equation seems wrong... x+y=2 4x+y=5 x=-y+5 -4y+20+y=5 -3y+20=5 -3y=-20+5 -3y=-15 -3y/-3=-15/-3 y=5 x=-5+5 x=0???
What's the main question?
How much lowfat milk(1% fat) and how much whole milk(4% fat) should be mixed to make 5 gal of reduced fat milk (2% fat)?
x + y = 5 0.01x + 0.04y = 0.02*5
Hmmm... how do you know what to put where?
It's pretty simple. For equation 1. find the total amount. it will be x+y = 5(total gallons)
Maybe so simple that I over think and get confused! LOL
for equation 2. Now we have 3 values left. 1%, 4% and 2% We have to make 2% so: 0.01x + 0.04y = 0.02 *5 *5 because total are 5 gals.
Where are you located Saifoo? I am so glad you grabbed my questions!
Lol. I'm located in another continent. Way far from US. I'm from Pakistan.
Wow... You speak and write English very well! Are you Pakistani or Indian? I am just curious... It is funny how the internet connects people, and we can find common ground and learn from one another....
Are you in Pakistan now? It is day there I imagine... It is late here in Indiana where I live in the U.S.
No. I'm a Pakistani. Living in Pakistan currently! :D Hehe. Yup. This world is shorter now. People can connect in seconds. It's 8:14am here. And i should be heading to bed soon. Haven't slept the whole night. :/ Been studying for exams.
It is very cool to meet someone in another country, again I am glad to know you!
A 17 year old teaching a 43 year old! WONDERFUL!!! :-D
Haha. Learning anything has no limits.
Well get some rest, I hope that you are okay with helping me, thank you so much sweetie!
Yup! Going in 5mins. If my mom sees me awake, i'm dead. D: Yes, sure. Knock me if you need any help. You're welcome ma'am.
Hey my Facebook is Susan-Jaxie Marie Hanna-Jackson, friend me if you would like! I look forward to learning more from you! Thank you so much again!!!
just sent you a request. You're welcome. :)
