Two numbers are in the ratio 9:7 if one number is 324, what is the other number?

Step-by-step explanation:

The ratio is 9 : 7

The first number is 324

Let's build the proportion for it.

9 : 7 = 324 :  x     [We've to find x]

=> 9 * x = 324 * 7

=> 9x = 2268

Dividing both sides by 9

=> x = 252

So, The other number is 252.

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!
