1. Hoover Dam spans the Colorado

Alona [7]

BEST estimate of this amount is $2(10^{7})$ . Correct option A. 2 x 10^7 .

<u>Step-by-step explanation:</u>

Here we have , Hoover Dam spans the Colorado River on the Nevada-Arizona state line. For its construction, the federal government purchased 21,670,000 pounds of gates and valves. We need to find BEST estimate of this amount . Let's find out:

21,670,000 pounds

⇒ 21,670,000 pounds

⇒ $21,670,000$

⇒ $2167(10^{4})$

⇒ $2.167(10^{3})(10^{4})$

⇒ $2.167(10^{3+4})$

⇒ $2.167(10^{7})$

Now, Rounding of 2.167 we get 2 ,So

⇒ $2(10^{7})$

Hence , BEST estimate of this amount is $2(10^{7})$ . Correct option A. 2 x 10^7 .
