umka2103 [35]

Answer:

The answer is 40.  

Step-by-step explanation:

First you can simply just list the multiples of 3 from 1-150, then cancel out all the multiples of 5 so,

3, 6, 9, 12, 18, 21, 24, 27, 33, 36, 39, 42, 48, 51, 54, 57, 63, 66, 69, 72, 78, 81, 84, 87, 93, 96, 99, 102, 108, 111, 114, 117, 123, 126, 129, 132, 138, 141, 144, 147.

15,30,45, 60,75,90, 105, 120,135 and 150 are multiples of 5 and so they are not included.

How to get 0.000006 from a scientific notion
Luden [163]

Answer:

6*10^-6

Step-by-step explanation:

You need a whole number for the scientific notion, right? To find that number above 1 and under 10, you can move the decimal point over until you get that number. Count the amount of spaces you moved the decimal point, and that's your number for scientific notation. To get the negative sign, you have to determine whether for scientific notation you make your number bigger or smaller. If you make it bigger, you have to put a negative sign on the exponent. If the number becomes smaller, it is a positive number. Hope this helps!
