Nina made a square picture frame that is 20 cm wide. She wants to wrap a blue ribbon around the outside of the frame two times. How long should the ribbon be?

The answer is 160 cm

Step-by-step explanation:

Square is a quadrilateral which has all its sides equal

Perimeter = 2l +2l

=20 times 2 + 20times 2

=40+40

=80

Wrap 2 times= 80 +80

=160cm

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!

gmt is 4 hrs ahead of edt so just add four hours to 1: 14: 20 (minutes and seconds stay the same)

gmt is 5: 14: 20

hope this !
