After a single sheet of paper is folded in half, there are two layers of paper. The same sheet of paper is repeatly folded in half. If function f represents the number of layers of paper that result when the original sheet of paper is folded a total of x times, then which equation could represents this function?

Take a sheet of paper. Make two folds (and crease them).to represent intersecting lines and discuss. Can more than two lines intersect in one point?

One corner of a long rectangular sheet of paper of width 1 unit is folded over so as to reach the opposite edge of the sheet. Find the minimum length of the crease.

Take a sheet of paper. Fold it as shown in the figure. Count the number of parts and the area of a part in each case. Tabulate your observations and discuss with your friends. It it a case of invers proportion ? Why ?

Sameera wants to celebrate the fifth birthday of her daughter with a party. She bought thick paper to make the conical party caps. Each cap is to have a base diameter of 10 cm and height 12 cm. A sheet of the paper is 25 cm by 40 cm, and approximately 82% of the sheet can be effectively used for making the caps after cutting. What is the minimum number of sheets of paper that Sameera would need to buy, if there are to be 15 children at the party ?

Radioactive disintegration is a first order reaction and its rate depends only upon the nature of nucleus and does not depend upon external factors like temperature and pressure. The rate of radioactive disintegration (Activity) is represented as -(dN)/(dt)=lambdaN Where lambda= decay constant, N= number of nuclei at time t, N_(0) =intial no. of nuclei. The above equation after integration can be represented as lambda=(2.303)/(t)log((N_(0))/(N)) Calculate the half-life period of a radioactive element which remains only 1//16 of its original amount in 4740 years: a) 1185 years b) 2370 years c) 52.5 years d) none of these

On one of 8 identical slips of paper, it is written 0, on the other it is written 3, on three of them it is written 1 on the top of the remaining three it is written 2. slips are folded and mixed throughly. One slip is drawn at random. If X is the number on the slip, find the probability distributoin of X. also find the mean and variance.
