Denise drew a scale drawing of a hotel. a room in the
hotel is 35 inches wide in the drawing. the actual room
is 14 feet wide. what scale did denise use for the
drawing?
5 inches:
feet

5 inches: 2 feet

Step-by-step explanation:

The scale that Denise uses is the ratio between 35 and 14 simplified.

Thus, after dividing both sides by their gcf 7, we get

35:14=5:2

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!

3x + 4y -25 =0 represents the amount of change sianna should recieve
