He table shows a proportional relationship between the distance a snail travels and the time it takes. what is the proportionality constant in centimeters per minute? time (minutes) distance (cm) 5 27.5 12 66 15 82.5 5.5 15 55 135.5

5.5cm/mins

Step-by-step explanation:

According to the table, it can be inferred that distance travelled by the snail is directly proportional to the time taken.

Let x be the distance travelled by the snail and y be the time taken.

Mathematically, x ∝ y

x = ky where k is the proportionality constant.

k = x/y

x1/y1 = x2/y2 = k

If x1 = 27.5, y1 = 5

If x2 = 66, y2 = 12

Substituting this values we have:

27.5/5 = 66/12 = 5.5

This shows that the proportionality constant is 5.5cm/min

according to this law, when unemployment goes up by 1%, gdp drops by 2%. in the question, unemployment rate goes from 2% to 5%, meaning unemployment goes up by 3%, so the gdp drops by 6%. thus the effect is a drop in gdp by 6%.
