Answer:

170

Step-by-step explanation:

Given that: x represents total number of keyboards ordered

                  y represents number of non-defective keyboards

And;

                  y = 0.9x - \frac{(0.9x)}{18}    .......................... 1

If the college ordered 200 keyboards, then x = 200. So that substituting the value of x in equation 1, we have;

y = (0.9 x 200) - \frac{(0.9*200)}{18}

  = 180 - \frac{180}{18}

  = 180 - 10

y = 170

The college received 170 non-defective keyboards.

Harlamova29_29 [7]
OCTA=8, an octagon has 8 sides, thus if one side is 6mm, then all sides, namely the perimeter, is 6+6+6+6+6+6+6+6, or 48.

now, we know what the apothem is.

\bf \textit{area of a regular polygon}\\\\
A=\cfrac{1}{2}ap~~
\begin{cases}
a=apothem\\
p=perimeter\\
-------\\
p=48\\
a=7.243
\end{cases}\implies A=\cfrac{1}{2}(7.243)(48)

Maru [420]

Answer:

(I need to know where the seven is located/placed.) Please give a clear answer or attach a photo next time so everybody who sees your question will understand.

Step-by-step explanation:

Comparing the numbers 700, 70, and 7; the digit "7" has a different value depending on its place within the number.

7 - ones place

70 - tens place

700 - hundreds place

The place value of the 7 determines the value it holds for the number. As the place moves to the left, the value of the number becomes greater by 10 times
