A chemist is using 362 milliliters of a solution of acid and water. If 12.1% of the solution is acid, how many milliliters of ac

PSYCHO15rus [73]

Answer:

The answer to your question is 43.8 mL of acid.

Step-by-step explanation:

Data

Total volume = 362 ml

12.1 % is acid

The Volume of acid = ?

Process

1.- Use the rule of three and cross multiplication to solve this problem.

362 ml ------------------- 100%

x ------------------- 12.1 %

x = (12.1 x 362) / 100

x = 4380.2 / 100

x = 43.802 ml

2.- Round your answer to the nearest tenth.

43.802 only consider the first decimal

43.8 mL

3.- Conclusion

A 12.1% solution of acid has 43.8 mL of acid.

The correct answer is option B which is $Cot\theta=\dfrac{24}{7}$ .

<h3>What is trigonometry?</h3>

Trigonometry is the branch of mathematics which set up a relationship between the sides and angle of the right-angle triangles.

Given that:-

$Sec\theta=\dfrac{25}{24}$

The value of cot theta will be calculated as:-

We know that sec theta is the ratio of hypotenuse and base and cot theta is the ratio of base and perpendicular so we will find the value of perpendicular by applying the Pythagorean theorem.

H² = P² + B²
P² = H² - B²

P² = 25² - 24 ² = 49

P = √49 = 7

Now the value of cot theta will be calculated as:-

$Cot\theta =\dfrac{B}{P}=\dfrac{24}{7}$

Therefore the correct answer is option B which is $Cot\theta=\dfrac{24}{7}$ .
