On a map, 2 cities are 15cm apart. If the scale states that 3cm = 10mi, about how many miles apart are these 2 cities in real life?

The cities would be 50 miles apart.

Step-by-step explanation:

There are 3cm for every 10 miles

if you divide 15 by 3 you would get 5

this mean you would have to multiply 5 x 10

5 x 10 = 50

Which makes the answer 50 miles

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!
