Answer:
2
Step-by-step explanation:
Answer:
L = 5S - 3
length of long side = 134.5 ft
length of short side = 27.5 ft
Step-by-step explanation:
L = 5S - 3
2L + 2S = 324 (keyword: enclose)
2(5S - 3) + 2S = 324
10S - 6 + 2S = 324
12S = 324 + 6 = 330
Thus S = 330/12 = 27.5 ft
Thus L = 5(27.5) - 3 = 134.5 ft
Answer:
1 extra worker
Step-by-step explanation:
If three workers load the truck in 8 minutes we have that:
3 workers = 8 minutes
We know that if we wanted to reduce the time at, for example, half, we would need to increase the workers in a half. More generally, if we want to reduce the time in 1/X me need to multiply the workers by X.
Here me need to reduce the time in 6/8 as 8*6/8 = 6. So, we will need:
3*8/6 = 24/6 = 4 workers.
So, we will need 1 more worker as we already have 3.
