Answer:
They're both proportional because everything's moving at a constant rate. Think of it this way: If a car travels for 50 miles per hour and the speed never changes, it's proportional. If that car at hour 1 traveled at 50mph and then at hour 2 traveled at 60mph, it would be nonproportional since the speed is increasing and changing.
Answer:
x=15
y=36
P=200
Step-by-step explanation:
You need to find the average length. You use the two numbers that gave you the range. (4.5-2.5)/2+2.5 = answer
<span>
so (4.5-2.5)=2 now 2/2=1 1+2.5=3.5mm
