Serjik [45]

Answer:

Perimeter = 15 cm

Step-by-step explanation:

The equation P=5s represents the perimeter P of a regular pentagon with side length s.

We need to find the perimeter of a regular pentagon with side length of 3 cm.

To find it, put s = 3 cm in the given equation.

P = 5(3) cm

= 15 cm

Hence, the perimeter of the regular pentagon of side length 3 cm is 15 cm.

Factor the quadratic expression to reveal the zeroes of the function it defines

Kazeer [188]

Answer:

Below.

Step-by-step explanation:

This factors to the product of 2 binomials like (x + a)(x + b), where a and b are 2 numbers.

40 = 4 * 10 and 14 = 4 + 10 so the answer is

(x + 4)(x + 10).

If we expand this we will get back to the quadratic expression:

(x + 4)(x + 10)

= x(x + 10) + 4(x + 10)

= x^2 + 10x + 4x + 40

= x^2 + 14x + 40.

Tion 15/30

vitfil [10]

The percentage of students that passed the exam is 25.2%

The given parameters;

number of the males, = 85

number of the females, = 30

percentage of the female that passed = 40%

percentage of the male that passed, = 20%

To find:

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%
