A chemist is using 333 milliliters of a solution of acid and water. If 19.6% of the solution is acid, how many milliliters of ac

sesenic [268]

65.27mm of acid is present in solution.

Step-by-step explanation:

Given,

Quantity of solution = 333mm

Acid Percentage = 19.6%

Quantity of acid = 19.6% of Quantity of Solution

$Quantity\ of\ acid=\frac{19.6}{100}*333\\Quantity\ of\ acid=\frac{6526.8}{100}\\Quantity\ of\ acid=65.27mm$

65.27mm of acid is present in solution.

A rectangle with sides 12 cm and 14 cm has the same diagonal as a square.

umka2103 [35]

Answer:

$a=\sqrt{170}$

Step-by-step explanation:

<u>Diagonal of a Square</u>

Given a square of length side a, the length of the diagonal is

$D=\sqrt{2}a$

The diagonal of a rectangle of sides x and y is

$D=\sqrt{x^2+y^2}$

The sides have lengths 12 cm and 14 cm, the diagonal is

$D=\sqrt{12^2+14^2}$

$D=\sqrt{340}$

Since this value is the same of the diagonal of certain square, we can say

$\sqrt{2}a=\sqrt{340}$

Dividing by $\sqrt{2}$

$\boxed{a=\sqrt{170}}$
