According to the problem we start with 6000 gal of E10 which means there is 10% of ethanol in this 6000, with ths information we can calculate the amount of ethanol already in the mixture:
The relationship between ethanol and total fluid can be represented like this:
Based on this relationship we can build the one that we are looking for:
the total solution will be:
where X is the E5 solution volume
and the TotalEthanol would be:
where E5ethanol (5% Ethanol 95% Gasoline) would be:
Now replacing in the relationship we found before:
Solving for X:
We should mix 1500 gal of E5 to make an E9 mixture
alr! so we know that the top line is straight, so it=180 degrees. then we know...
2x + 20 + 2x - 4= 180
4x + 16=180
4x=164
x=82
youre welcome!
Determine which of the following terms is a function: a. (1,2) (2,4) (3,5) c. (1,2) (2,4) (2,6) b. (1,2) (2,3) (1,5) d. (1,2) (3

In a function, X does not repeat.
Your answer is A.
<span>a (1,2) (2,4) (3,5)
</span>there are different x values for
each point, so this IS A FUNCTION.
<span>
b. (1,2) (2,3) (1,5)
</span>there are two values of x being 1,
so this is NOT A FUNCTION.
<span>c. (1,2) (2,4) (2,6)
</span>there are two values of x being 2
so this is NOT A FUNCTION.
<span>
d. (1,2) (3,5) (3,7)</span>there are two values of x being 3,
so this is NOT A FUNCTION.
hope this helps and have a great day!
