<span>1 Liter = 1.05 quart.
1/1.05 Liter = 1.05/1.05 quart = 1 quart.
Replacing this value of quart in the equation below.
1 gallon = 4 quarts
1 gallon = 4 * 1/1.05 Liters
1 gallon = 3.80952380952
Total oil consumption per year in gallons is 600,000,00
So, total oil consumption per year in liters is obtained by:
600,000,000 * 3.80952380952 = 2285714285.71 liters
Converting to scientific notation, we have 2.28571 * 10^9 liters.</span>

Answer:
- 4
- -2
- 4
- 2
- -2±√2
Step-by-step explanation:
In order to fill the first blank, we need to look at the second line to see what the coefficient of x is.
1. x² +<u> </u><u>4 </u>x +2 = 0
The constant is subtracted from both sides to get the second line.
2. x² +4x = <u> -2 </u>
The value that is added on the third line is the square of half the x-coefficient: (4/2)² = 4
3. x² +4x +<u> 4 </u> = -2 +4
On the fourth line, the left side is written as a square, and the right side is simplified. The square root is taken of both sides.
4. √(x +2)² = ±√<u> 2 </u>
Finally, 2 is subtracted from both sides to find the values of x.
5. x = <u> -2 ±√2 </u>
Answer:
283.5
Step-by-step explanation:
A=πr^2
A=π(9.5^2)
A=π(90.25)
π x 90.25=283.5 (rounded to the nearest tenth)

68/100
Step-by-step explanation:
answer is 68/100
<h3>
Answer: Solution is x = -2</h3>
You have two equations with y1 = f(x) and y2 = g(x).
We're looking for the values of x such that f(x) = g(x). This is the same as trying to solve y1 = y2.
The first row of the table shows y1 and y2 having the same value 5. So we just record the x value that goes with these y values.
