Answer:
All answers are in the steps below.
Explanation:
Question 1(a):
An equation to show the relationship between s and t is:
s = t × k
s = tk
Question 1(b):
The complete table is attached below.
Question 1(c):
Since we now know k = 1/2
s = t × 1/2
s = 1/2t
*You can now easily tackle questions 1(d, e & f).
Question 2(a)
92/35 is not equal to 83/23 thus no proportional relationship between the two variables.
Question 2(b):
20/8 = 12.5/5 = 2.5
There is a proportional relationship between the two quantities here and the constant (k) is 2.5
*Question 3 not complete.
