So first turn it into an improper fraction, so it would be 7/5×2/1. So once multiplied, your answer will be 14/5. then to express as a decimal, you do 14÷5, which would be 2.8
I think it would be 84 + 0.45m + 108.
Which simplified could be 0.45m + 192. Hope it helps! :)
Answer:
Equation of circle in standard form with centre (0, – 10) and radius 6.
Step-by-step explanation:
We need to write equation of circle in standard form with centre (0, – 10) and radius 6.
The equation of circle is:
where (h,k) is centre of circle and r is radius
We are given centre (0,-10) so, h=0, k=-10 and radius r = 6
Putting values and finding equation:
So, equation of circle in standard form with centre (0, – 10) and radius 6.
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
Answer:
I think its 21.6 or 22 (Mostly 21.6 though) Sorry if its not right but i'm mostly sure of it like this!
