A chemistry teacher needs to mix a 40% salt solution with a 90% salt solution to make 25 qt of a 60% salt solution. How many quarts of each solution should the teacher mix to get the desired result?

for ex: the reciprocal of 3/4 is 4/3. it is the opposite.

reciprocal definition:

a mathematical expression or function so related to another that their product is one; the quantity obtained by dividing the number one by a given quantity.

v = 1/3 a^2h

step-by-step explanation:

the volume is 1/3 a^2h.

a

step-by-step explanation:

the denominator cannot be the same as one of the factors.

8 denominator times 2 denominator = 16

and 7 numerator time 11 = 77

77/16= 77/16 ( they cannot be further simplified)
