The rules are


Let me show you why with a couple of examples: suppose we want to multiply

Since powers are just repeated multiplications, we have

Similarly, we have

Answer:
The constant of proportionality is 0.3, or K=0.3.
Step-by-step explanation:
The chart I attached shows points that are plotted on the proportional line. In order to find the constant of proportionality from these points, you have to divide the amount of change by the number of years. For example, 3 divided by 10 or 6 divided by 20. This results in 0.3, which means that every year, there is 0.3 centimeters of change in the sea level.
It depends on the how much the ratio makes but i think it is 72 but not positive but it also might be 6 but that is with additional information
Answer:
$50
Step-by-step explanation:
12 x 30 = 360
960 - 360 = 600
600/12 = 50
The whole equation simplified to one answer is 5
