There are 240 students in the 7th grade the ratio of girls to boys is 7: 5 what percent of the students are boys

about 41.67% are boys

Step-by-step explanation:

In terms of "ratio units", the fraction of students that are boys is ...

5/(5+7) = 5/12

As a percentage, that is ...

(5/12)·100% = 41 2/3%, about 41.67%

The percent of student that are boys is about 41.67%.

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.

the roots are ( x-intercepts) x=-0.5,x=1,x=3

the y-intercept is the point (0,3)
