A) 5 + 4x = 25
B) x = 5
C) It is not accurate but it is precise.
D) 17234 in
E) 300 seconds

For A, she spends 5 minutes stretching and walks 4 laps at unknown speed x.  This gives us 5 + 4x.  She spends a total of 25 minutes at the track, so we have
5+4x = 25

For B, we solve this by first subtracting 5 from both sides:
5 + 4x - 5 = 25 - 5
4x = 20

Now we divide both sides by 4:
4x/4 = 20/4
x = 5

For C, it is not accurate because the measurement it gives is not exactly 0.25 miles.  It is precise, however, as it does not vary greatly.

For D, we first multiply 0.272 by 5280:  0.275(5280) = 1436.16 ft.  Now we multiply by 12:
1436.16(12) = 17233.92 in ≈ 17234 in

For E, we take 5 minutes and multiply by 60:
5(60) = 300 seconds

There is 5000 ml water in a fish tank. THen 20% water is evaporated per week. calculate the volume of water left after 4 Weeks.
LenaWriter [7]

Answer:

The answer to your question is: V = 2048 ml

Step-by-step explanation:

Data

Volume = 5000 ml

20% is evaporated per week

Volume of water left after 4 weeks = ?

Process

            1st week               5000 ml   -----------------  100 %

                                              x          -----------------      20 %

                                              x = (20x 5000) / 100

                                              x = 1000 ml

After a week there are = 5000 - 1000 = 4000 ml left

            2nd week              4000 ml   ----------------  100 %

                                                x          ----------------   20%

                                               x = 800 ml

After two weeks, there are = 4000 - 800 = 3200 ml left

         third weeks              3200 ml  -----------------  100 %

                                              x         ------------------    20%

                                             x = 640 ml

After three weeks there are 3200 - 640 = 2560 ml left

           

         4rd                             2560 ml  ----------------- 100%

                                                x           ----------------  20%

                                             x = 512 ml

After four weeks there are 2560 - 512 = 2048 ml left

31 cars are in a race. In how many different ways can cars finish in order in the top 4 positions?
cupoosta [38]

Answer:

755,160 ways

Explanation:

We're told that 31 cars are in a race.

Considering the order in which the cars can finish in the top 4 positions, any of the 31 cars can finish in the first position, any of the remaining 30 cars can finish in the second position, any of the remaining 29 cars can finish in the third position and any of the remaining 28 cars can finish in the fourth position, so the different numbers of ways can be determined as seen below;

31\times30\times29\times28=755,160\text{ ways}
