The pattern of zeros in the product when multiplying by powers of 10 is a result of our base-10 decimal system. Each place value in a decimal number represents a power of 10.
When you multiply a number by a power of 10, you are essentially shifting its digits to the left by the number of places equal to the exponent of 10.
Let's illustrate this with an example. Suppose we have the number 456, and we want to multiply it by powers of 10:
1. 456 multiplied by 10:
- When we multiply 456 by 10, we are essentially shifting all the digits one place to the left. So, we get 4560. Here, we've added one zero.
2. 456 multiplied by 100:
- When we multiply 456 by 100, we are shifting all the digits two places to the left. So, we get 45600. In this case, we've added two zeros.
3. 456 multiplied by 1,000:
- When we multiply 456 by 1,000, we are shifting all the digits three places to the left. So, we get 456000. Here, we've added three zeros.
And so on...
In general, when you multiply a number by 10 raised to the power of "n," you will add "n" zeros to the end of that number. This is a fundamental concept in our decimal number system and is why the pattern of zeros emerges when multiplying by powers of 10. Each power of 10 represents a place value shift, and adding zeros simply extends the number in the same manner.

The volume of our figure is 72 cubic inches.
9. We are trying to find the triangle that fits the description of obtuse and scalene. An obtuse triangle is one which has one angle with a measure of more than 90°. A scalene triangle is one in which no two sides are similar.
Triangle 9a fits this description, so you would mark yes on it.
Triangle 9b does NOT fit the description, since all angles have a measure of less than 90°, so we will mark a no on it.
Triangle 9c also does not fit the description, since it has an angle with a measure of exactly 90° (as indicated by the little square in the corner of the angle), so we will mark no on this one as well.
And there we have it.
Hope that helped! =)
