I would really appreciate someone’s help Fred needs 65 mL of 12% sucrose solution to do his science experiment. He needs to mix a 5% sucrose solution with some 30% sucrose solution to get the 12% solution he wants. How much of each solution should Fred use? (Include units in your answer. More information.)
Fred needs to use of 5% sucrose and of 30% sucrose to make 65 mL of 12% sucrose solution.

the discriminant is 64 + 4*1*12 = 112

this is prime.

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

proportions are fractions that equal to each other. so if two fractions are the same, they are proportional.

let's check the answers to see if they are proportional.

question a is not proportional because you can't turn 1.5/3 to 3/9. if you try to multiply 1.5/3 by 2 or 3, you wont get 3/9. it's impossible to make the fractions the same.

question b is not proportional because you can't turn 22/33 to 4/6. 33 can't go into 6.

question c is proportional because when you multiply 2 and 3 by 71, you would get 142/213, and those fractions equal to each other

question d is proportional because when you divide 14 and 7 by 2, you would end up with 7/3.5, and those fractions equal to each other.
