40 to 25 i don’t know what that mean i’m a little dumb

Step-by-step explanation:

(cant remeber the exact word right now) think of it like this. if your school is going on a feildtip, there are 40 students in a group while there are 25 adults in a group.  so the equation you are trying to find is

x:1         what you would do is divide 40 both numbers by the second number so you would divide 40 by 25 to get you 1.6

clearly it is not talking about people. but the answer is 1.6 : 1

first option

a function is a relation in which an input is paired with exactly one output.

so, let's find the right answer.

in our first option, our inputs are january, february, and march. the outputs are 30, 28, and 25. each input has it's own output. this is correct!

our second option we know is incorrect, because ms. valverade has two outputs, dogs and cats. this is not a function.

our third option is incorrect as well. the yellow square has two ouputs, the square and the triangle.

lastly, in our fourth option, we see the number 7 two times with a different output. therefore, this is not a function.

remember: each input must be paired with only one output!
