In a table do you have to list the x and y coordinates in order (largest to smallest)?

Arisa [49]

Answer:

No. (maybe)

Step-by-step explanation:

For expressing the corresponding values of x and y, <em>any ordering will do</em>. It is usually convenient for the user of the table if there is some recognizable order (so that a value can be found without searching the entire table). The usual expected order is by x-value, smallest to largest.

Some problem statements may specify that the table entries be listed in order. In those cases, yes, the <em>table values must be listed as specified</em>. (This accounts for the (maybe) answer, above.)

<h2>The crime gets cleaned up at 2:00 PM</h2>

Step-by-step explanation:

Let the work be w.

Batman can clean up all of the crime in Gotham City in 8 hours working alone.

$\texttt{Rate of batman,}r_b=\frac{W}{8}$

Robin can do the same job alone in 12 hours.

$\texttt{Rate of Robin,}r_r=\frac{W}{12}$

Robin starts work at 8:00 AM and Batman Joins at 10:00 AM.

Let the time of completion of work after Batman's joining be t.

We have time of working of Robin = t + 10:00 -8:00 = t + 2

$t\times \frac{W}{8}+(t+2)\times \frac{W}{12}=W\\\\12t+8t+16=96\\\\20t=80\\\\t=4hours$

After 4 hours of 10:00 Am work gets completed.

Time = 10:00 AM + 4 hours = 2:00 PM

The crime gets cleaned up at 2:00 PM

A rectangular playground has a perimeter of 180 feet. If the width of the playground is 24 feet less than the length, what is th

Blababa [14]

P = 2(L + W)
P = 180
W = L - 24
now we sub
180 = 2(L + L - 24)
180 = 2(2L - 24)
180 = 4L - 48
180 + 48 = 4L
228 = 4L
228/4 = L
57 = L

W = L - 24
W = 57 - 24
W = 33

so ur length (L) = 57 ft and ur width (W) = 33 ft
