Mathematics

0.9 repeat is not 1. 0.999, nor .9999999999 are not equal to 1. If the expansion of 9’s is stopped at any finite point, the resulting fraction (for example, 0.9999 = 9,999/10,000) will never be equal to 1. Each time a 9 is added, the error decreases, but will not take the number to 1. With each 9 added, the error becomes ten times smaller. The is no number that the sequence of 9’s gets arbitrarily close to. The error would look like 1/infinity, however, it is more precise to say that the limit of the sequence is zero.

PLEASE HELP !!! - after tip you gave a total of $321.75. If the original price of the meal was $300, what percent tip was applie
yan [13]

Answer: 7.25%

Step-by-step explanation:

There are a few ways to do this, but the easiest might be to set up a proportion:

321.75/300 = x percent/100 percent

Now cross multiply;

300x = 321.75(100) = 32,175

Divide both sides by 300 to solve for x:

300x/300 = 32,175/300

x = 107.25 This means that the tip was 7.25% on top of the $300 meal.

Illusion [34]
Would need the net to answer. but to find the answer you need to find the slant height of the square pyramid, the slant height is the hypotenuse of the right triangle formed by the height and half the base length. Use the pythagorean Theorem
