Math Write Up for “The Pumpkin Problem” Problem Statement: I went shopping for pumpkins the other day. I needed to buy three pumpkins. For some strange reason, instead of weighing the pumpkins individually the pumpkin farm weighed them in pairs. I wasn't there to see which pumpkin was weighed with which. But the three pair weights were 36 lbs., 43 lbs., and 49 lbs. Process: When I finished all my other homework, I asked my sister for help with this problem. She told me to told me to get a piece of paper, divide it into three columns, write the three pair-weights that were given in the problem, and find possible solutions that equal those three pair-weights. After finishing what she told me to do I came up with these possible solutions: - Pumpkin I weighed 15 pounds, Pumpkin II weighed 21 pounds, and Pumpkin III weighed 28 pounds - Pumpkin I weighed 16 pounds, …show more content…
I can keep going, but there are still many more solutions to be found. Solution: At this point, my sister came over and asked how I was doing on the problem. I told her I was fine. She asked me to explain how I answered the problem, so I told her my explanation while giving her the opportunity to look over my work to make sure it was correct. The first two steps (dividing the paper into three parts and finding different ways to get the weight of each pumpkin that was given) was what was happening as I was getting deeper into the problem and finding more and more solutions to it. In the end, it really helped to use a three column sheet to organize the different ways to get the three pair-weights. I knew I was getting the right solutions every time I used the three column sheet because when I added together the pumpkin I and pumpkin II, I got the right answer for their weight all together. The same thing happened to pumpkins I and III, and pumpkins II and
Figure 4 reflects a decreasing mean weight per plant as density of planted seeds increases-- from a high of 11.73 grams (2 seeds) decreasing gradually from between 3 to .
The experiment required our group to find out the mass and thickness of a single penny from a group of pennies, with each group of pennies’ being from different years. Tools such as calipers and eight scales were used to find the average mass and thickness of a single penny from each year. Our general hypotheses before conducting the experiment was that both the mass and the thickness of pennies would go down with each newer year of pennies.
adding on lean body mass. They are usually “stacked” which is a process of taking two or
5) Find the experimental mass of both the c-clamp and the empty pan by using the formula from page one. Record this as mtotal.
A very wealthy king has 8 bags of gold, which he trusts to some of his caretakers. All the bags have equal weight and contain the same amount of gold, all the gold in the kingdom. Although, the king heard a story that a woman received a gold coin. The king knew it had to be his gold so he wanted to find the lightest bag in the 3 weighing, but the mathematician thought it could be done in less, so I need to find out the least amount of weighing it takes to find the lightest bag. Also, the king used a pan balance for all of his weighing.
The materials necessary for this experiment are: four plastic cups numbered 1-4, a scale, six ice cubes, cold deionized water, a pipet, a heat lamp, two LabQuests, four temperature sensors, some paper towels, and four partners in total. The first thing you will need to do is use the tare function to zero out the mass of cup #1, then add three ice cubes to the cup. Record the mass of the ice cubes. Once the mass is recorded, add cold deionized water to the cup until the total mass is between 99.80 g and 100.20 g. Use the pipet to add and subtract water as needed. Put cup #1 aside when this is accomplished. Repeat this process for cup #2. Continuing to cup #3, use the tare function to zero out the mass of the cup and then add between 99.80
(b) The amount of relief to be given was calculated on the price of a gallon loaf of bread (weighing 8lb. 7oz.) and the number of children a man had.
Our original mass of the fruit loops were .812 grams. The mass that we got for iron fillings were .104 grams. We got .121 grams of zinc oxide, .391 grams of sucrose, and .181 grams of stearic acid. The total mass that we recovered was .797 grams. When we calculated our percent recovery our calculations showed that we recovered 98.15% of the original .812 grams of the cereal. I believe that we didn’t fully retrieve the .812 grams because whenever we would add a solution to the solid and pour it through a filter there would always be little speckles of residue stuck in the beaker. When you are transferring the mixture a lot sometimes you lose some of the mixture and in this experiment we transferred the solid multiple times. Overall I believe that our experiment was a success and we retrieved a good amount of the
There were two major differences, first the ramp that the cart was pulled up was at an angel, and second the total mass was not a constant. After finding the error, I believe it would be best to redo the the experiment. Our first trial had an error of only 19%, but as our tails went on it drastically became worse with our highest error at 123%. In the end, the average error we had was 83.84%. We firmly believe the error is not in our math( Dr. Armstrong told us our formula was correct), but rather the setup of our experiment. For our angel, we constantly used 3 degrees. This was found using an app from an Iphone. It has come to my attention that we may have been not been using the app correctly. Not only that, in our rush to complete this section, There is a possibility that our pulley and our ramp may have been out of line. There are many factors that could have caused the error, the best way to find said error would be to redo the experiment to see if the same results
...h time to set up the plastic sheets and we can easily pick the few tomatoes still in the field. It’s getting all those pumpkins from the backfield to the shed that’s going to take the time.”
We then put the stopwatch on and left them for half an hour. After we weighed each potato tube and recorded our results. We did the experiment twice. We did this to make sure our results were correct. Preliminary method: We did everything the same as in our other experiment except we
I answered, “Yes sir.” I left the room, and this time I didn't hit the side of the doorway. I went into my room, jumped on the bed, and got out my phone. After about an hour, my sister woke up not knowing she should've stayed in bed that day due to how she was going to by the victim of my frustration that was built up inside of me. My sister and I both were sitting in our rooms when my mom called us from the kitchen. We hurried to the kitchen and she reminded us that we needed to clean up the house, while she and my dad go to run some errands. We whined, but eventually started to clean. I had to clean up the living room, play room, my parents room, and my room. My sister only had to finish cleaning her room and do the dishes. She started at the dishes and I started cleaning up the living room. I finished
This made my parents mad and they went into my sisters room to talk to her and after that, I felt guilty about what I said and I told my parents the truth that it wasn’t all her fault and that it was my fault that we were screaming at eachother and my parents were still mad at me but
Pest or potential problems- The pumpkins plant has lots of pests that will be problematic towards the pumpkins growth. Certain insects such as vine borers , aphids, squash bugs and snails will hurt the pumpkin plant. Aphids are notorious small insects that will eat a broad range of vegetables. They are harmful towards the pumpkin because they eat the insides of the pumpkin leaves. To get rid of these small pests, the usage of ladybugs will do the trick.Squash bugs along with vine borers prey upon the pumpkin’s leaves and vines. Squash bugs aren’t bugs that travel alone and aren’t easy to get rid of. Vine borers can be taken out of the pumpkins vines, while getting rid of squash bugs can be more difficult.
