Step-by-step explanation:

8 gallons of regular gas with 10% and 2 gallons with 85%

8 x 10 =80%

2 x 85 =170%

170+80=250%

10 gallons each with 100%, so 10 x 100 =1000%

250% of 1000% = 1/4 or 25% ethanol

Hope this helps!

several friends each ad 2/5 of a bag of peanuts left over from a baseball game. they realized that they could have bought two fe

Anarel [89]

Well to my knowledge we need to find how many people with that amount equal 2 for the amounts of peanuts. So lets go one by one.

2 friends = 4/5 of a bag of peanuts left together. - 0.8 left

3 friends = 6/5 of a bag of peanuts left together. - 1.2 left 

4 friends = 8/5 of a bag of peanuts left together. - 1.6 left 

5 friends = 10/5 of a bag of peanuts left together. - 2 left 

So, there are 5 friends total.

5 friends
