0.05(2x +4) +0.25x =2.65
Step-by-step explanation:
The decimals are in the right places. A. would have been correct but it would have had to be 265 instead of 2.65. They put the decimals in the incorrect place.
Answer:
d. inputs decrease while outputs remain the same -- True here productivity increases.
Step-by-step explanation:
In any organization productivity is a measure of efficiency
Productivity is normally expressed as ratio of output/input
Obviously when output increases productivity increases and also
when input decreases productivity increases.
a. inputs and outputs increase proportionately -- False here no change.
b. outputs decrease while inputs remain the same -- False here productivity decreases.
c. inputs increase while output remains the same -- False here productivity decreases.
d. inputs decrease while outputs remain the same -- True here productivity increases.
Answer:
16 years.
Step-by-step explanation:
Please consider the complete question.
Assume that the suburb has a population of 686,000 and is growing at a rate of 4000 per year. Assume that the city has a population of 942,000 and is declining at a rate of 12000 per year. In how many years will the populations of the suburb and the city be equal?
Let x represent number of years.
Growth function would be 
and decline function would be 
.
To find the time when both populations will be equal, we will equate both functions as:
Therefore, in 16 years the populations of the suburb and the city will be equal.
