Answer:
80000
Step-by-step explanation:
Significant figures are any number but zeroes.
However, in some cases, zeroes also count as significant figures.
- Zeroes are significant figures when between other non-zero numbers.
- Zeroes are significant when you see a dot on the right indicating that zero is not a place holder.
- They are <u>not</u> significant when serving as place holders, such as zeroes on the right side of a number. For example, .004 has 1 sig fig. The 2 zeroes on the left aren't sig figs because they're just place holders.
- Zeroes on the <u>right</u> side of a decimal are also significant.
The answer is 71 since you count from the tenth space. So the first significant figure would be 7 and the second significant figure would be 0. As we know that we round up one number of the previous number is 5 or bigger.
The answer would be 1 as it’d go 4 in each direction
30? I think thats the answer
