Answer:
Therefore 160 workers needed to build 16 miles of highway in 15 weeks.
Step-by-step explanation:
Given that,
the amount of time to build a highway varies inversely with the number of workers and varies directly with the length of the highway.
i.e
T= time, L= length of highway and W= number of workers.
So,we can rewrite the above equation
Here, = 100 worker, = 4 miles, = 15 weeks
= ?, = 16 miles, = 15 weeks
[ Multiply both sides]
Therefore to build 16 miles of highway in 15 weeks 160 workers needed.
Answer:
The measure of a snart is 2 and that of a snert is 8.
Step-by-step explanation:
Represent the size of a snert by e and that of a snart by a.
Then e - a = 6. This assumes that e > a.
2e + a = 18. Substitute e - 6 for a, obtaining:
2e + (e - 6) = 18.
Simplifying, we get
2e + e - 6 = 18, or
3e = 24, and so
e = 8
Remembering that e - a = 6, we have 8 - a = 6. Then a must be 2.
The measure of a snart is 2 and that of a snert is 8.
