:24% of students in a class are girls. if there are less than 30 students in this class, how many students are there? how many girls are there?

Ok a point t on a segment with endpoints d(1, 4) and f(7, 1) partitions the segment in a 2: 1 ratio. find t. you must show all work to receive credit.

Let f(x) = 5/x and g(x)=2x2+5x. what two numbers are not in the domain of f o g
