What is 0.000000012 in scientific notation

how do you know?

1.2 x 10 -7

Step-by-step explanation:So we wanna know what 0.000012 is in scientific notation.

With scientific notation, you want to end up with something that looks like number times ten raised to the power of x, which would look like:

numberx10x.

The number in the front must always be more than 1, but less than 10. This means the number can be anything from 1.0 to 9.9.

So for the problem you have here we have 0.000012. This means the smallest number in the front could be 1.2 Not 12 and not .12 The number in the front must always be more than 1, but less than 10.

So now we have the first part of the scientific notation: 1.2x10. To know what power to raise the 10 to, count how many zeros there are to the right after the decimal. With our 0.000012, there are 4 zeros, which means 4 spaces to the right, so the 10 would be raised to -4

BUT if we raised that 10 to the power of -4, our notation would look like 0.12x10-4 and remember, that first number cant be lower than 1.

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
