Answer:

38 = 4s

s = 9.5 inches

Step-by-step explanation:

The perimeter of a square is found by

P = 4s where s is the side length

Substituting that we know the perimeter is 38 inches

38 = 4s

Divide each side by 4

38/4 = 4s/4

19/2 = s

9.5 inches is the side length

What is the radius of a circle with an area of 78.5 cubic inches? Use 3.14 for pi. Enter your answer in the box.
Korvikt [17]

Answer:

r =5 in

Step-by-step explanation:

Area of a circle is given by

A = pi r^2

We know the area and pi

78.5 = 3.14 r^2

Divide by 3.14

78.5/3.14 = 3.14 /3.14 r^2

25 = r^2

Take the square root of each side

sqrt(25) = sqrt(r^2)

5=r

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%
