Answer:
14.4 covers/hr.
Explanation:
First, we need to identify how much covers are produced in 1 hour, which will be total produced divided by the total time:
covers/hr = 120/10
covers/hr = 12
If the production will be increased by 20%, it means that new production will be the initial one plus 20% (0.20) of it:
12 + 0.20*12 = 14.4 covers/hr.

Answer:
The correct answer is - 15 hours.
Explanation:
Half-life an element is the time required to decay the half amount of the initial amount of the element and is represented by t1/2.
The formula for the calculating initial amount
n(i)=n(r)⋅2^n
where
n(i) - the initial number of moles of element
n(r) - the number of moles remained amount after the given time
n - the number of periods,
= time T, where T is the half-life.
n(i)=n(r)⋅2^n
n(i)/n(r) =2^n
1/16 =2^n
n= 4
The half life = 60/n
= 60/4
= 15 hours.
