Answer:- 
Step-by-step explanation:
The given ration is 16 :40
In fraction, the above ratio can be written as : 
To write the above fraction in lowest terms, we need to divide the numerator and the denominator by the greatest common divisor.
Since, 
, Hence, 8 is the greatest common divisor of 16 and 40.
Now, divide the numerator and denominator by 8, we get
1 g/ml is 8.3454 lbs/gal. So you multiply 1.09 into 8.3454 and your answer is 9.1 lbs/gal
Anyone can see it's "Maximum" & it's max. vertex is (0, 2) 'cause x-coordinate is at origin & y is at 2.
In short, Your Answer would be Option D
Hope this helps!
<span> by using calculator, these are the answers:
√20 = 4.47213595499958
√18 = 4.24264068711928
but without calculator,
√20 = √(4x5)
= √4 x √5
= 2 x √5
= 2√5
√18 = √(9x2)
= √9 x √2
= 3 x √2
= 3√2 </span>
