Five brothers are going to take turns watching their family's new puppy. How much time will each brother spend watching the puppy in single day if they all watch him for an equal length of time?

4 hours 48 minutes

Step-by-step explanation:

Right now, in this problem the whole set comprises of a single day and you know that there are 24 hours in a day.

In order to solver the problem,you have to draw a number line of length 24 and then separate it into 5 equal parts.  (because there are total five brothers)

or simply, just divide 24 by 5.

= 24/5  => 4 hours

lets convert 4/5 hour to minutes, as you know there are 60 minutes in one hour.

therefore, 4/5 x 60= 48 minutes.

Each brother will spend 4 hours watching the puppy in single day, which is likewise 4 hours 48 minutes

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!

answer: a and b
