There are 12 female students and 18 male students in a class. which of the following expresses the ratio of female students to male students in simplest form?
a.3/2
b.3 to 2
c.2/3
d.3: 2

C. 2/3

Step-by-step explanation:

12 female / 18 male

Dividing by 6 we get:

2 female / 3 male

or 2/3

To convert miles per hour to meters per second divide by 2.237

128 miles per hour / 2.237 = 57.22 meters per second.

Using the first equation:

57.22 = sqrt(2 x 9.81 x h)

Remove the sqrt by raising both sides to the second power:

57.22^2 = (2 x 9.81 x h)

Simplify Both sides:

3274.1284 = 19.62h

Divide both sides by 19.62:

H = 3274.1284/ 19.62

H = 166.88 meters
