Answer:
the theoretical minimum number of workstations is 9.
Step-by-step explanation:
to determine the theoretical minimum number of workstations we use the formula below:
Number of workstations = sum of total task time / cycle time
Given information :
Task times = 8, 4, 7, 9, 10, 14, 12, and 8 minutes
sum of total task time = 8+4+7+9+10+14+12+8
= 72 minutes
cycle time = 8 minutes
Thus,
Number of workstations = 72 minutes / 8 minutes
= 9

.
Step-by-step explanation:
We have been given that one a recent trip, Cindy drove her car 290 miles, rounded to the nearest 10 miles, and used 12 gallons of gasoline, rounded to the nearest gallon.
The range of miles driven would be between 
because number of miles in rounded to nearest 10 miles.
The range of gallons of gasoline would be 
because number of gallons of gasoline in rounded to nearest gallon.
To find mileage, we will divide number of miles by number of gallons.
The possible number of gallons of gasoline will be 12.5 gallons for 285 miles to get the minimum number of miles.
Similarly, the possible number of gallons of gasoline will be 11.5 gallons for 295 miles to get the maximum miles.
Therefore, our required range would be and .
Answer:
5
Step-by-step explanation:
Natalie
100 + 10x
Her sister
25 + 25x
Where
x = number of months
Equate Natalie and her sisters equation
100 + 10x < 25 + 25x
100 - 25 < 25x - 10x
75 < 15x
Divide both sides by 15
x < 75 / 15
x < 5
