Answer(or question to Mentor): Hey! This is Sara. I have been thinking about this problem and I have a question. You know how the question says how many feet did the storm surge in 2002? Also the other question. Well are you supposed to figure this out including the ¼ that is in the ground or just the part that is showing?
Thanks! Sara

Mentor Reply: Hi Sara,
Thank you for responding. Part A is asking for the amount of water covering the stilt from the point where it sticks out of the ground, this is the "surge." Your answer will focus on the part of the stilt that is showing, but knowing that 1/4 of the stilit is in the ground will help you figure out the total length of the pole. Let me know if you need anymore help. I'm looking forward to hearing from you.
Sincerely, Andrea

I hope you get my response this time. I'm not sure why it didn't go through last time. Thanks for responding and trying the problem.
In my previous response I had given you the hint: since 1/4 of the stilt is in the ground, calculating the length of the remaining part of the pole will help you figure out the storm surge.
Since this is our last submission for the problem I'll tell you how I solved it. By the information given in the problem, I figured out that the entire pole (including the part in the ground) was 10 feet tall. Since 1/4 of the pole was in the ground, I divded the 10 feet into fourths. This means each fourth measures 2.5 feet. This also tells me that the part of the pole sticking out of the ground measures 7.5 feet (2.5 + 2.5 + 2.5). In 2002 the surge covered 3/4ths of the stilt, so therefore 3/4ths of 7.5 equals 5.625 feet or 5 5/8ths feet. Then 1/4 was left dry so therefore 1/4th of 7.5 equals 1.875 feet or 1 7/8ths feet.
I hope this explanation helps to clarify any questions you have. Thanks again for trying. Keep up the good work.
Sincerely, Andrea

Answer(or question to Mentor): Hey Andrea!!
Thank you for the last submission I could read it and it was a big help!!
I think I might have gotten the answer to the new question.
For number one I got that there were 330 calories in a cheeseburger. I got this by first multiplying the 14 grams of fat that were in the cheeseburger by how many calories are in each gram of fat. I multiplied 14 and 9(which is how many calories are in each gram of fat. I got 126 calories. Then I multiplied all the carbohydrates by how many calories are in each carbohydrate. There are 36 carbohydrates so I multiplied that by the number of calories in each carbohydrate which is 4. I got 144 calories. Then lat but not least I multiplied all the protein by how many calories were in each gram of protein. So I multiplied the 15 grams of protein by 4 which is how many calories are in each gram of protein. That was 60 calories. Then I added all those numbers together and got my answer which is 330 calories a cheeseburger.
Never mind I just read the question and this one is not even there anymore.
Sorry for making you read all that it was there yesterday!!!
Well for the new number one I got 6.06 percent. Iam not sure if this is right but first I divide 330 into 2000. I got 6 and a remander of six so I just made it 6.06 percent. If this is wrong could you give me a hint as of how to do this?
Thanks

I agree that our response page looks kind of crowded this time.
You are correct about a cheeseburger having 330 calories. Thank you for the wonderful explanation. Somehow the original part one to this problem disappeared, but you would need to figure out this information in order to do the rest of the problem. I appreciate your attention to detail.
For part one of the current problem posted you weren't sure if the answer is 6.06 percent. This is incorrect but I would be more than happy to help you figure out how to do this. Since you know a cheeseburger has 330 calories and the RDA is 2000 calories/day then Charle has ingested 330 of the 2000 calories, correct? The fraction would be the calories ingested over the calories per day. To convert a fraction into a decimal you divide the numerator by the denominator then move your decimal point two places to the right and add a percent sign(this is the same as multiplying by 100). This is because percent means per hundred. For example 10% is the same as saying 10 out of 100 or 10 hundredths (10/100= .1, move decimal to the right twice or multiply by 100,= 10%)
Part two is simalar except you use the grams of fat per cheeseburger over the total grams of a cheeseburger (so you would have to add up grams of fat, carbs. and protein to get the total grams). Try this one again.
Let me know if you need any more help. I hope you find my hints helpful. I'm looking forward to hearing from you.
Sincerely, Andrea

Good answer. Glad that you attempted to teach about percent, which is what I was just writing to you about in the last problem!
You have just one spelling error: simalar
