Blue and green dye are mixed in a 7 : 4 ratio to make 44 litres of a teal- coloured dye. A further 8 litres of green dye are added to the mixture. What
is the new ratio of blue to green dye in its simplest form?

7:6

Step-by-step explanation:

7+4 = 11. 44/11 = 4. That means there are 7*4 = 28 blue dye and 4*4 = 16green dye. 16 + 8 =24. Blue dye to green dye would then be 28/24 = 14/12 = 7/6, so the ratio is 7:6

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!
