A rectangular yard measuring 26 ft by 36 ft is bordered (and surrounded) by a fence. Inside, a walk that is 2 ft wide goes all t
cestrela7 [59]

Answer:

  232 square feet

Step-by-step explanation:

The outside dimensions of the yard are 26 ft by 36 ft, so its total area is ...

  yard including walk = (26 ft)(36 ft) = 936 ft²

The dimensions of the yard inside the walkway are 22 ft by 32 ft, so that area is ...

  yard not including walk = (22 ft)(32 ft) = 704 ft²

The difference in these areas is the area of the walkway:

  walkway area = (yard including walk) - (yard not including walk)

  = (936 -704) ft² = 232 ft² . . . . area of the walk

_____

Another way to figure this is to consider the length of the centerline of the walkway. That is the perimeter of a rectangle that is 24 ft by 34 ft. The perimeter (centerline length) is 116 ft, and the width of the walk is 2 ft, so its area is ...

  (116 ft)(2 ft) = 232 ft²

How many nanoseconds does it take for a computer to perform one calculation if it performs 6.7 × 10^{7} calculations per second?
crimeas [40]

Answer:

<u><em>the comuter does 1 calculation in 1.5*10^{-17} nanosec</em></u>

Step-by-step explanation:

<u><em>First step: we need to write all terms in nanosec, as we know:</em></u>

<u><em>1[nanosec]= 10^{-9}[sec]</em></u>

<u><em>The computer does 6.7*10^{7} [\frac{calculation}{sec}]</em></u>

<u><em>if we multiplicate for \frac{sec}{nanosec*10^{*9}}, from the units convertion.</em></u>

<u><em>6.7*10^{7} [\frac{calculation}{sec} * \frac{sec}{nanosec*10^{*9}}</em></u>

<u><em>6.7* 10^{16} [\frac{calculation}{nanosec}]</em></u>

<u><em>Now doing a simple three rule we have this:</em></u>

<u><em>6.7 * 10^{16} calculation in ⇒ 1 nanosec</em></u>

<u><em>1 calculation in ⇒ \frac{1 nanosec* 1calculation}{6.7*10^{16} calculation }</em></u>

<u><em>So, we found: the comuter does 1 calculation in 1.5*10^{-17} nanosec</em></u>
