If 48% of the students in a certain college are female and there are 1440 female students, what is the total number of students
Andrews [41]

Answer:

3000 students

Step-by-step explanation:

If 48% of the students are female, and there are 1440 female students, we can set up a percentage proportion, assuming x is the total amount of students.

\frac{1440}{x} = \frac{48}{100}

We can use the cross products property to find the value of x.

1440\cdot100=144000\\\\144000\div48=3000

Hope this helped!

Find the midpoint of the line segment joining the points R(-5,5) and S(4.6).
tigry1 [53]

Hey there! I'm happy to help!

To find the x value of the midpoint, you add the x values and divide by 2.

-5+4=-1

-1/2=-1/2

For the y value, you add the y values and divide by 2.

5+6=11

11/2=5 1/2

So, the midpoint is (-1/2, 5 1/2).

Have a wonderful day! :D
