In her science classroom Jane noticed that the lengths (in inches) and the weights (in ounces) of the class's pet snakes were di

rectly related by the equation y = kx, where x is the length and y is the weight. Use the information in the table to find k, the constant of proportionality.

Answer: C) 30.0 ounces

Step-by-step explanation:

Use one of the ordered pairs that are given to find the value of 'k', the CONSTANT of variation. This number will not change, hence the word 'constant'.

15 = k*6; dividing both sides by 6 we get k = 2.5; The equation used for the table is y = 2.5x

You can find any value now by using this formula.

y = 2.5*12

y = 30

Pls help, I don’t understand how to do this
MAVERICK [17]

Answer:

5 parts are shaded and 4 parts are white so:

There are 9 parts all together.

We can then form ratio's of the white areas and the shaded areas:

White Area Ratio =

\frac{4}{9}

Shaded Area Ratio =

\frac{5}{9}

Let the area of sqaure be equated to x, which means let the entire area of the square equal to x:

x = Area of whole square

Now we can form an equation :

\frac{5}{9} x = 165

So now we just need to solve for x:

x = \frac{165}{ \frac{5}{9} }

x = 297

The area of the square is:

297 {cm}^{2}
