We need to make sure the units are the same. I will convert km to cm

3 km *1000m/1km * 100cm/1m =300000 cm

Now we can write the equation

P * 300000 = 30

Divide each side by 300000

P 300000/300000 = 30/300000

P =.0001

Changing this from decimal to percent

P = .0001*100 = .01 %

A glacier advanced 12 feet during a 16-day period in January. The same glacier advanced 18 feet during a 24-day period in February. Are the ratios of feet to days proportional for these two periods of time? explain in two sentences how you got your anwser

Answers

Yes, both of these ratios are proportional. You could either plug it into an equation and solve it, or do like I did and divide. If you divide 16 by 12, you get 0.75. If You divide 24 by 18, you also get 0.75, therefore they are equal. The reason why I divided by the numbers that I did is because you're trying to figure out how much it increased and if it was equivalent. They increased 0.75% of their size that they started with. I hope this helps!

The wheels of a monster truck are 66 inches tall. Find the distance the monster truck travels when the tires make one 360-degree rotation

Answers

Answer:

About 207 inches
