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.

-13 you can just put -9 + -4 in a calculator and get -13
We have that
scale factor=1 in/2.5 miles
<span>the actual area of a lake is 12 square miles
</span>we know that
[area on the map]=[scale factor]²*[area actual]
[area on the map]=[1/2.5]²*[12]-----> 1.92 in²
the answer is
1.92 in²
