A rule for creating a pattern is given below. The rule begins with a number called the input and creates a number called the output.
Rule: Divide the input by 3. Then add 7 from the result to get the output.
Which input and output table works for the rule?
Choose 1

(Choice A, Checked)
A
Input Output
15 11

(Choice B)
B
Input Output
30 3

(Choice C)
C
Input Output
18. 13

its c

Step-by-step explanation:

15/3 equals 5 plus 7 would be 12 so thats wrong

30/3 equals 10 plus 7 would be 17 so thats wrong

18/3 equals 6 plus 7 would be 13 so that right ergo the answer is c

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

the correct answer is 1: 2

step-by-step explanation:

hope this your welcome : )
