A mixture of paint calls for 1/6 of a cup of red paint and 2/3 cups of yellow paint. How many cups of red paint would be needed for every 1 cup of yellow paint?

of red paint would be needed for every 1 cup of yellow paint.

Step-by-step explanation:

Given:

A mixture of paint calls for 1/6 of a cup of red paint and 2/3 cups of yellow paint.

Now, to find the cups of red paint needed for every 1 cup of yellow paint.

So, to get the cups of red paint needed we use unitary method:

For cup of yellow paint needed of a cup of red paint =  

Thus, 1 cup of yellow paint needed of a cup of red paint =

On simplifying it:

Therefore, of red paint would be needed for every 1 cup of yellow paint.

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!
