Answer:
16 hours
Step-by-step explanation:
let t be time, n the number of computers and w the number of workers, then
t = ← k is the constant of variation
To find k use the condition n = 30, w = 6 and t = 10 , then
10 = ( multiply both sides by 6 )
60 = 30k ( divide both sides by 30 )
2 = k
t = ← equation of variation
When w = 5 and n = 40 , then
t = = = 16 hours
The correct answer is maybe 3
Answer:
$85
Step-by-step explanation:
100%-20%=80% and 80% = 0.8

Answer:
6,528 divided by 8 is 816
6528/8 = 816
6348 divide by 9 is 705.44..... ♾️
Answer:
65 because 12 plus 9 is 21 then 3 times 21 is 65
