Answer:

II case.

Step-by-step explanation:

Given that a catering company prepared and served 300 meals at an anniversary celebration last week using eight workers.

The week before, six workers prepared and served 240 meals at a wedding reception.

Productivity is normally measured by number of outputs/number of inputs

Here we can measure productivity as

no of meals served/no of workers

In the I case productivity =\frac{300}{8} \\=37.5

In the II case productivity = \frac{240}{6} \\=40

Obviously II case productivity is more as per worker 40 meals were served which is more than 37.5 meals per worker in the I case.

Which of the following constants can be added to x2 + 2/3 x to form a perfect square trinomial?
Nimfa-mama [501]

Answer:

Step-by-step explanation:

Next time, please be sure to share the possible answer choices.  Also, please use " ^ " to indicate exponentiation:  x^2 + (2/3)x.

Let's actually "complete the square" here:

Starting with x^2 + (2/3)x, identify the coefficient of the x term (it is 2/3).

Take half of that, which results in 2/6, or 1/3.

Square this result, obtaining (1/3)^2 = 1/9.

Add to, and then subtract from, this square:

x^2 + (2/3)x + 1/9 - 1/9

Rewrite x^2 + (2/3)x + 1/9 as the square of a binomial:

(x + 1/3)^2 - 1/9

In review:  add 1/9 to, and then subtract 1/9 from,  x^2 + (2/3)x
