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:
1595 ft^2
Step-by-step explanation:
The answer is obtained by adding the areas of sectors of several circles.
1. Think of the rope being vertical going up from the corner where it is tied. It goes up along the 10-ft side. Now think of the length of the rope being a radius of a circle, rotate it counterclockwise until it is horizontal and is on top of the bottom 20-ft side. That area is 3/4 of a circle of radius 24.5 ft.
2. With the rope in this position, along the bottom 20-ft side, 4.5 ft of the rope stick out the right side of the barn. That amount if rope allows for a 1/4 circle of 4.5-ft radius on the right side of the barn.
3. With the rope in the position of 1. above, vertical and along the 10-ft left side, 14.5 ft of rope extend past the barn's 10-ft left wall. That extra 14.5 ft of rope are now the radius of a 1/4 circle along the upper 20-ft wall.
The area is the sum of the areas described above in numbers 1., 2., and 3.
total area = area 1 + area 2 + area 3
area of circle = (pi)r^2
total area = 3/4 * (pi)(24.5 ft)^2 + 1/4 * (pi)(4.5 ft)^2 + 1/4 * (pi)(14.5 ft)^2
total area = 1414.31 ft^2 + 15.90 ft^2 + 165.13 ft^2
total area = 1595.34 ft^2
Mm i think 7 you just have to divide like the number by 2 like 40 divided by 2 is 20 then divide the 20 and you get 10 idk
