We have been given that a librarian noticed that 60% of seventh graders checked out fantasy books. We are asked to find the number of seventh graders from 240 seventh graders, who would checkout fantasy books.
To solve our given problem, we need to find 60% of 240.
Therefore, 144 seventh graders would checkout fantasy books.
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
