Math question: It's in the box.?
How would I do this problem? There are two boxes: one marked A and one marked B. Each box contains either a million dollars or a deadly snake that will kill you instantly. You must open one box. On box A there is a sign that reads: "At least one of these boxes contains one million dollars." ON box B there is a sign that reads:" A deadly snake that will kill you instantly is in Box A. You are told that both signs are true or both are false. Which box do you open? Be careful, the wrong answer is fatal!
I need help on a physics question?
Two forces are applied to a 50-kg box. One is 60.0 N to the south and the other is 80.0 N to the east. These are the only forces acting on the box. The magnitude of the acceleration of the box is: 1. 0.50 m/s2 2. 1.5 m/s2 3. 10 m/s2 4. 2.0 m/s2 5. 5.2 m/s2 Please show all work. I really don't know where to begin in order to solve this problem.
Math question help, asap.?
Hello, I'm having a math test next week and got a study guide from my professor. I'm stuck on this question only, if you could help, that would be amazing. Thank you! -Cabot creamery is packing a pallet of 20-lb boxes of cheddar cheese to send to a local restaurant. There are five layers of boxes on the pallet, and each layer is four boxes wide by five boxes deep. a. How many boxes are in one layer? b. How many boxes are on the pallet? c. What is the weight of the cheese on the pallet?
Two people are carrying a box trig question?
Gravity has to act downward. You have two vectors; One acting at 47.9 degrees and one at 54.6. The angle between the vectors is 54.6-47.9=6.7 degrees. Then, draw a parallelogram. Since consecutive angles are supplementary, the angle adjacent to the angle between the vectors is 173.3 degrees. Then, since opposite sides of the parallelogram are congruent and the resultant is the diagonal of the parallelogram, you can use the law of cosines. So, f^2=94^2+123^2-2(94)(123)(cos173.3) f=216.6 The answer would be B) 217 lb
Two boxes, one with a mass of 60 kg and the other with a mass of 90 kg are in contact and on a smooth surface.
This is F=m*a The total mass of the system is 150 kg, so 800=150*a a=16/3 m/s^2 The force between the boxes is the reaction force of the acceleration of the 90 kg box: F=90*a =90*16/3 =480 N j
Did Gaurav Agarwal really solve the question where we are supposed to add three odd numbers to get 30? If yes, what was his solution?
use 15 in first boxuse 9 in second boxnow rotate page 180 degreesuse 9 in the third boxnow rotate page back 180 degreesthats 15+9+6 is 30another answer is use 15 in first than 15 in second and than , in third as it is written in question as "fill the boxes using" so generally we think only as numbers to fill but you can use , ( and ) along with numbers to fill
I am unable to reply to a comment on one of my questions. (No reply box) Can someone explain?
there has to be a reply button below the comment written for your question.click that button below to make the box for writing comments appear...so check again and reload the page properly.crowded servers sometimes tend to give half loaded pages without proper sub-links.otherwise there are no settings change required for these kind of problems, as far as i know....
There are three boxes, one contains only apples, one contains only oranges, and one contains both apples and oranges. The boxes have been incorrectly labeled such that no label identifies the actual contents of the box it labels. Opening just one box, and without looking in the box, you take out one piece of fruit. By looking at the fruit, how can you immediately label all of the boxes correctly?
Open the box that is labeled "Apples and Oranges".You know that since none of the labels are correct, the box must either contain only apples, or only oranges.Suppose that you remove an apple from that box. Therefore, that box is the "Apples Only" box. (If, in fact, you removed an orange from the box, you can swap “Apples” and “Oranges” for the rest of the description; the same reasoning applies).One of the two remaining boxes must be the "Oranges Only" box. The remaining two boxes are labeled "Apples Only" and "Oranges Only". Since the labels cannot match, the “Oranges Only” label cannot have “Orange Only” contents.Therefore, the one labeled "Apples Only" is the box that contains only oranges, and the box labeled "Oranges Only" is the box that has both kinds of fruit.
Probability questions....how to tackle this?
a) In Box 1 there are 100 defective bulbs. Therefore the chance that the first one drawn is defective is 100/1000. The chance that the second one is defective (given that the first one drawn is not replaced) is 99/999 Therefore the chance that the first two drawn are both defective = (100/1000) x (99/999) = 0.00991 or 0.99% ie almost 1%. In box 2 there are also 100 defective bulbs but here there are 2000 in the box. In a similar fashion to the explanation for Box 1, the probability that the first two drawn are defective = (100/2000) x (99/1999) = 0.00248 or 0.25% ie a quarter of 1% Assuming there is equal probability of choosing either box, the probability of the two bulbs drawn being defective is 50% x Box 1 (0.00991) + 50% x Box 2 (0.00248) = 0.004955 +0.00124 = 0.0062 or 0.62% ie 6.2 tenths of 1%. b) Given that the two bulbs are defective, the probability that they came from box 1 is the proportion of the total chance of defectiveness compared to box 2. ie 0.00991 / (0.00991+0.00248) = 0.00991/ 0.01239 = 0.79984 = 80%
