Answer:
20
Step-by-step explanation:
its is 20 for both because the 0 and 20 are the same.
If she already gets the first two, thats a given 100% situation. then it is just 1/4
78.33 (3 rounds down)
0.0605 (5 rounds up)
288.60 (8 rounds up, but there is a nine, so nine becomes 0 and 5 becomes 6)
0.101 (8 rounds up)
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
