The formula for speed is the total distance traveled over time. We shall calculate the 2 speeds individually- before and after lunch. Afterwhich, we shall add them together and divide by 2 to get the average.
Before lunch s = 132 mi / 3 hr = 44 mi/hr
After lunch s = 240 mi / 5 hr = 48 mi/hr

Ave s= 48 + 44 / 2
Ave s= 46 mi/hr

Therefore the correct answer is A.

The numbers 0.1, 12, 15 and 124 can all be classified as counting numbers?​
andreyandreev [35.5K]

Answer:

No

Step-by-step explanation:

Counting numbers are considered to be whole numbers greater than zero. Whole numbers are positive numbers without decimals or fractions, so 12, 15, and 124 can be classified as counting numbers, but not 0.1.

hope this helps!!!

If 3x^2 -2x+7=0, then(x-1/3)^2=
Harman [31]
3x² - 2x + 7 = 0.

Using method of completing the square.

3x² - 2x = 0 - 7

3x² - 2x = -7          Divide through by 3.

x² - 2/3x = -7/3   ...........(d)

Coefficient of x = -2/3,  half of it = 1/2*-2/3 = -1/3    square of it = (-1/3)² = 1/9

We add (1/9) to both sides of equation (d)

<span>x² - 2/3x = -7/3 
</span>
<span>x² - 2/3x + 1/9 = -7/3 + 1/9

We factorize it by making using of half of the coefficient,  -1/3
</span>
(x - 1/3)² = -7/3 + 1/9

<span>(x - 1/3)² = -20/9
</span>
That's the answer as asked by the question.   -20/9
