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!

Explain why the expression 7•3x is not equal to the expression 21x
rusak2 [61]
The expression 7•3x is not equal to the expression 21x. You might think that the two expressions are the same since 7x3 is 21 but the first expression is a dot product. This kind of expression includes the magnitude and direction of the vector in an expression, for example, <span>7•3x. The second expression, 21x, expresses only the magnitude and does not include the direction.</span>
