Mathematics: Problem #4 using elimination or substation how many liters of each type should the chemist use to produce 50 liters of the solution that is 20% of sodium?

the length of the unknown leg is 10 cmStep-by-step explanation:Use the Pythagorean theorem to solve the problem. The theorem states that the square of the hypotenuse equals the addition of the squares of the two legs:since we know the length one of the legs (24 cm) and also of the hypotenuse (26 cm), we can solve for the unknown leg in the equation above:Therefore, the length of the unknown leg is 10 cm....

the length of the unknown leg is 10 cm

Step-by-step explanation:

Use the Pythagorean theorem to solve the problem. The theorem states that the square of the hypotenuse equals the addition of the squares of the two legs:

hyp^2=leg_1^2+leg_2^2

since we know the length one of the legs (24 cm) and also of the hypotenuse (26 cm), we can solve for the unknown leg in the equation above:

$hyp^2=leg_1^2+leg_2^2\\(26\,cm)^2=(24\,cm)^2 +leg_2^2\\leg_2^2 = (26\,cm)^2-(24\,cm)^2 \\leg_2^2=100\,cm^2\\leg_2=\sqrt{100\,cm^2} \\leg_2=10\,cm$

Therefore, the length of the unknown leg is 10 cm.
