BEST estimate of this amount is 
. 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
⇒ 
⇒ 
⇒ 
⇒ 
⇒ 
Now, Rounding of 2.167 we get 2 ,So
⇒
Hence , BEST estimate of this amount is . Correct option A. 2 x 10^7 .
He would have paid $15.94 and since he’s paying with a $20 bill, all you would do is subtract $15.94 from $29. This leaves us $4.06.
The given equation -4y + 4y + 2 = 2 have infinite solutions.
According to the given question.
We have a equation.
-4y + 4y + 2 = 2
Solve the above equation for finding the number of solutions.
-4y + 4y + 2 - 2 = 2- 2
⇒ 0 = 0
The coefficients and the constants match after combining the like terms. This gives us a true statement.
We can see that in the final equation, both sides are equal. Therefore, it has an infinite solution.
Hence, the given equation -4y + 4y + 2 = 2 have infinite solutions.
