, 8 technicians can test 560 samples in 36 hours. How long
Yakvenalex [24]

Answer:

0.75 days (im a bit unsure but i tried my best, hope this helps :) )

Step-by-step explanation:

If it takes 8 technicians 36 hours to test 560 samples, find how many technicians can test 525 samples.

8: 560

x: 525

x= 7.5 (which is considered 7)

Then, find how long it takes to sample 525 samples, when 560 are done in 36  hours;

560: 36

525: x

x= 33.75 (which is considered 34 hours)

The last step is to check how long 15 technicians take to sample 525 samples when 8 can do the same number in 34 hours. this is inverse proportion so dont forget to flip one numerator and denominator

8; 34

15; x

it will become

15:34

8: x

x= 18 hours

Divide by 24 for days hence 0.75 days

Kali runs 10 laps around a track each day. each lap around the is 400 meters. how many days will it take kali to run a total of
mr Goodwill [35]

Answer:

3 days

Step-by-step explanation:

First multiply 10 by 400 to find how many meters she runs each day.

10*400 = 4,000

1 kilometer = 1,000 meters

Now convert the meters to kilometers

To convert it to kilometers you divide 4,000 by 1,000, which equals 4 kilometers.

So she runs 4 kilometers each day.

Now divide 12 by 4 to find out how many days it will take to run 12 kilometers.

12/4 = 3 days
