Answer:
Step-by-step explanation:
Answer:
Will no explain too much in details.
The bottom rectangle has sizes 21cm*9cm, so its area is 189cm^2.
The remaining rectangle has sizes 6cm*7cm(16-9=7cm),so its area is 42cm^2.
The area of the object is 231 cm^2.
The perimeter is 21+9+16+6+(16-9)+(21-6) = 74 cm.
The answer is C because x2 is a parabola

Given:
Overhead cost = 34,816
Production cost per lawn mower = 388
Average cost per lawn mower = 660
Total Production cost + Overhead Cost = Total Cost
Total Cost ÷ # of lawn mowers produced = Average cost per lawnmower
Let x be the number of lawn mowers produced:
(388x + 34,816)/x = 660
x((388x + 34,816)/x) = x * 660
388x + 34,816 = 660x
34,816 = 660x - 388x
34,816 = 272x
34,816/272 = 272x/272
128 = x
There are 128 lawnmowers manufactured.
To check:
388x + 34,816 = total production cost.
388(128) + 34,816 = 49,664 + 34,816 = 84,480
84,480 ÷ 128 = 660 ave cost per unit
