3 0

Answer:

1, 2, 5 and 6 are the answers.

Step-by-step explanation:

2 is correct because the arrow shows that the number line continues till infinity. 5 is correct because any fraction is possible as no restriction of integer value is placed. Any number less than 7 is not included. There are some confusions with 1 as it's not a solid color, So, I assume -7 is not included.

How many grams are 2.7x10-^4 grams

andrew-mc [135]

Answer:

0,00027 grams!

Step-by-step explanation:

This is a scientific notation problem.

When a number is followed by a $10^{-1}$ , it means that said number has one zero at the beginning.

In this case, the number is followed by $10^{-4}$ , so that means that 2.7 has four zeros at the beginning. So, 2.7x $10^{-4}$ grams is equal to 0,00027 grams! (always the comma goes after the first zero).
