A(b+c)=ab+ac
we have
9(72)=9*?+9*2
c=2
sub, but it must be equal to minus 2 from 72
7(70+2)=9*70+9*2
the question mark is 70
and the restult of the equation is 648
?=70
Her age after 11 years is 11x
Before 5 years her age is x-5
Answer:
(a) 2min/15units
(b) 1min/20units
(c) The bottleneck stage is cutting. The process capacity is 450units/hour
(d) The capacity of the new employee should be 1unit/2sec. The process capacity will increase four times
Step-by-step explanation:
(a) Cycle time for stage cutting for 2 employees = 16sec/2units × 1min/60sec = 2min/15units
(b) Cycle time for stage sealing for 1 employee = 3sec/1unit × 1min/60sec = 1min/20units
(c) Process capacity of stage cutting = 15units/2min × 60min/1hour = 450units/hour
(d) If the capacity of the new employee is 1unit/2sec, the process capacity = 1unit/2sec × 3600sec/1hour = 1800units/hour. The process capacity increases 4 times (1800/450 = 4)
The answer is: 2y^2-20y+12
