Answer: true
Step-by-step explanation:
It’s 00.9
Step-by-step explanation: I just took the test I know
In this problem, you are asked to write a number in
scientific notation. In figures, 78 million would look like this:
78,000,000
To write this to scientific notation, you have to move the
decimal point to the left until you will get a number between 1 and 10.
Here, you will have to move the decimal point 7 times to get
7.8
The exponent of the scientific notation is the number of
times you moved your decimal point. Since the movement of decimal point is
going to the left, you will have a positive exponent.
The scientific notation would look like this:
7.8 x 10^7
The <em>correct answer</em> is:
We can use the associative property to write 70 as 7*10. We can do this same process to write 6000 as 6*1000. This gives us:
(7*10)*(6*1000)
Using the commutative property, we can rearrange the factors of this problem
(7*6)*(10*1000)
7*6 is in our multiplication tables, and we know that powers of 10 allow us to just add the correct number of zeros. This means we would have 7*6=42, and have 4 zeros, for 420000.
