For this problem I recommend using the explicit version of the arithmetic sequence formula
an = a1 + (n – 1)d.

The first term is a1, the common difference is d, and the number of terms is n. an is the final number we are looking for.


We shall substitute in the common difference and 2 since every hour 2 more people will know. Also the first term is equal to 2. an is 450 because that's what we are looking for.


the equation looks like 450= 2 + (n – 1)2. Now we evaluate. n = 225. 225 terms will pass, then all 450 students will know the rumor. Each term will equal 1 hour . 225 hours converts to 9 full days and 9 hours. So it will take 9 days and 9 hours for every student to know the rumor at that rate.

A drawing of a triangle. The base equals 15 centimeters and height equals 8 centimeters.
Effectus [21]

Answer:

17

Step-by-step explanation:

If we are finding the long angled side (the hypotenuse), we must keep in mind the Pythagorean theorem. This states that in order to find the answer, we must follow: A squared + B squared = C squared. A and B are known as the legs and we use these for A and B. After squaring both 15 and 8 we get 225 + 64= 289. Now that we have our answer of 289, we can square this to find our hypotenuse which is 17. To find the square root, you multiply different numbers by themselves until you reach your answer. 17 x 17 = 289 so the hypotenuse is 17 centimeters long. I hope this helps! :)
