Answer:

A. \frac{1}{5} log_{3}x +log_{3}y

Step-by-step explanation:

We have the expression

log_{3} (\sqrt[5]{x} *y)

As these two values are being multiplied, we can separate the two and the sum of them will be equal to the multiplied version

log_{3}\sqrt[5]{x} +log_{3}y

The \sqrt[5]{x} can be rewritten as x^{\frac{1}{5} }. This allows us to use the exponent rule. This means that it can be written as

\frac{1}{5} log_{3}x +log_{3}y

The percentage of students that passed the exam is 25.2%

<u />

<u>The given parameters;</u>

  • number of the males, = 85
  • number of the females, = 30
  • percentage of the female that passed = 40%
  • percentage of the male that passed, = 20%

<u>To find:</u>

  • the percentage of students that passed the exam

The number of the male students that pass the exam;

= 0.2 \times 85 \\\\= 17

The number of the female students that pass the exam;

= 0.4 \times 30 \\\\= 12

The total number of students in the school;

= 85 + 30

= 115

The total number of the students that passed the exam;

= 17 + 12

= 29

The percentage of students that passed the exam;

= \frac{total \ number \ that \ passed }{total \ number \ of \ the \ students} \times 100\% \\\\= \frac{29}{115} \times 100\%\\\\= 25.2 \%

Thus, the percentage of students that passed the exam is 25.2%

9 x 15= 135

The mat area:

15 + 3= 18

9 + 3= 12

12 x 18 = 216

<u>216 - 135 = 81</u>
