A web site was hit 300 times over a period of 15 days Show that over some period of 3 consecutive days, it was hit at least 60 t
marshall27 [118]

Answer:

We will divide the 15 days in five periods of 3 consecutive days each.

Now to solve this we will use the pigeonhole principle.

This states that if (N+1) pigeons occupy N holes, then some hole must have at least 2 pigeons.

So, we have n=300 pigeons  and k=5 holes.

[\frac{n}{k} ]=[\frac{300}{5} ]

Hence, there is a period of 3 consecutive days in which the website was hit at least 60 times.

How much medicine should he add to the food?​
quester [9]

Answer:

Paul should give 18 teaspoons of medicine to his dog.

Step-by-step explanation:

It is stated in the question that for every 12 pounds, 3 teaspoons of medicine is to be given to the dog.

This implies that:

12 pounds = 3 teaspoons

1 pound = 3/12 teaspoons

             = 1/4 teaspoons                      <em> ( by cross multiplication )</em>

<em />

<h3>72 pounds = 1/4 * 72 teaspoons</h3><h3>                   = 18 teaspoons</h3><h3 />

Hence, Paul should add 18 teaspoons of medicine to his dog's food.
