1 hour = 60 minutes = 3600 seconds = 1/24 day

Divide every number above by 2 to get 1/2 hour and its equivalent numbers.

1/2 hour = 30 minutes = 1800 seconds = 1/12 day

can you help me with this: did I put these in order and how will I know I did so: .9,1.1,.10 38 and .10299
tatuchka [14]
Your list of numbers needs a bit of clarification.

You wrote:  <span>.9,1.1,.10 38 and .10299

I have to make some assumptions here, and to ask whether you meant the following:

</span><span>.9,  1.1,  .1038   and   .10299

If so, now's the time to look for the smallest and the largest of these numbers.  The smallest is 0.10299:

smallest
</span>
0.10299
<span>0.1038
0.9
1.1

</span>.9,  1.1,  .1038   and   .10299

If my list disagrees with yours, please ensure that you have copied down these four numbers correctly and then try again (on your own) to order them correctly from smallest to largest.

Answer:

164 m^2

Step-by-step explanation:

You can think of the shaded area in different ways. One of the ways is the entire outer colored rectangle minus the area of the small white rectangle inside.

The large colored rectangle is 12 m by 15 m.

The inner rectangle is 8 m tall. The width is 12 m - 5 m - 5 m = 2 m

A = 12 m * 15 m - 2 m * 8 m

A = 180 m^2 - 16 m^2

A = 164 m^2

Two trains leave a town at the same time heading in opposite directions. One train is traveling 12 mph faster than the
klemol [59]

Answer:

I'm going to paint you a picture in words of what this looks like on paper.  We have a train leaving from a point on your paper heading straight west.  We have another train leaving from the same point on your paper heading straight east.  This is the "opposite directions" that your problem gives you.  

Now let's make a table:

                distance       =        rate      *       time

Train 1

Train 2

We will fill in this table from the info in the problem then refer back to our drawing.  It says that one train is traveling 12 mph faster than the other train.  We don't know how fast "the other train" is going, so let's call that rate r.  If the first train is travelin 12 mph faster, that rate is r + 12.  Let's put that into the table

              distance        =        rate        *        time

Train 1                                        r

Train 2                                    (r + 12)

Then it says "after 2 hours", so the time for both trains is 2 hours:

         

              distance        =        rate        *        time

Train 1                                        r           *          2

Train 2                                  (r + 12)       *          2

Since distance = rate * time, the distance (or length of the arrow pointing straight west) for Train 1 is 2r.  The distance (or length of the arrow pointing straight east) for Train 2 is 2(r + 12) which is 2r + 24.  The distance between them (which is also the length of the whole entire arrow) is 232.  Thus:

2r + 2r + 24 = 232 and

4r = 208 so

r = 52

This means that Train 1 is traveling 52 mph and Train 2 is traveling 12 miles per hour faster than that at 64 mph
