Answer:
4. 35 times larger
Step-by-step explanation:
Doing Question #4 Only
4.
Before we see this problem's solution. Lets get a background.
Suppose something has an area of "A" sq. meters.
and
Suppose another land has an area of "B" sq. meters.
and suppose A > B
If we want to know how many times A is larger than B, we simply have to divide the larger one (A) by the smaller one (B).
Now, onto our question:
We want to know how many times larger the national is than state park. So we divide the area of national by the area of state. That would be:
[tex]\frac{7*10^8}{2*10^7}[/tex]
Since the numbers are in scientific notation, we look at the rule below on how to divide scientific notation numbers:
[tex]\frac{a*10^b}{c*10^d}=(\frac{a}{c})*10^{b-d}[/tex]
Now, we apply the rule:
[tex]\frac{7*10^8}{2*10^7}\\=\frac{7}{2}*10^{8-7}\\=3.5*10^1\\=3.5*10\\=35[/tex]
So, the national park is 35 times larger than the state park.
