Answer:
4 h 45 min
Step-by-step explanation:
<span>The basic formula is r * w * t = q
r = quantity of output produced per worker per unit of time.
w = number of workers.
t = time
q = quantity of output produced.
you can solve this formula for w to get:
w = q / (r * t)
if the quantity of work increases by 60%, then you get 1.6 * q and the formula for w becomes:
w = (1.6 * q) / (r * t)
a 60% increase in the quantity of would result in a 60% increase in the number of workers required, assuming the amount of time available was the same.
not assume that each worker can produce 25% more output per unit time.
then you get 1.25 * r and the formula for w becomes:
w = (1.6 * q) / (1.25 * r * t)
this formula can also be written as (1.6/1.25) * (q/(r*t)).
this results in 1.28 * (q/(r*t)) which can also be written as (1.28 * q) / (r*t)
this says that the 60% increase in the quantity of work produced can be handled with a 28% increase in the number of workers required, assuming the amount of time available is the same, and assuming that the productivity of each worker has increased by 25%.
</span><span>The number of workers must be increased by 28%.</span>
Answer:
10
Step-by-step explanation:
By the Pythagorean Theorem:
![c=\sqrt{6^2+8^2}=\sqrt{36+64}=\sqrt{100}=10](https://tex.z-dn.net/?f=c%3D%5Csqrt%7B6%5E2%2B8%5E2%7D%3D%5Csqrt%7B36%2B64%7D%3D%5Csqrt%7B100%7D%3D10)
