Enter numbers into the table so that the paired values are in a proportional relationship.

Step-by-step explanation: We are given a table of x and y values:

x :  1     3    ?      7      9

y :  ?    18   30   72   54.

The values of x and y are in proportion.

Let us check the ratio of values of x to y.

When x=3, we have y =18.

Therefore x/y = 3/18 = 1/6.

So, all values of x and y should be in ratio 1/6.

So, for x=1, y= 6×1 = 6

For y =30 , x= 30/6 = 5

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

where are the choices?
