8 sides
the exterior angle = 180° - 135° = 45° ( exterior/ interior are supplementary )
the sum of the exterior angles of a polygon = 360°
number of sides =
= 8
Step-by-step explanation:
step 1. (-0.4)(0.16) = -0.064
step 2. (0.625)(-0.08) = -0.05
step 3. -1.2(-5.1) = -6.12

Answer:
The minimum cost per unit is obtained for an order of 8 units.
Step-by-step explanation:
Since the total cost is modeled by;
C(x)=5x²+320
Then;
1 unit costs; C(x)=5(1)²+320 = 325
cost per unit 325/1 = 325
8 units costs; C(x)=5(8)²+320 = 640
cost per unit = 640/8 = 80
80 units costs; C(x)=5(80)²+320 = 32320
Cost per unit = 32320/80 = 404
The minimum cost per unit is obtained for an order of 8 units.
No he did not because 20% of 250 is 50 and there are 90 students not 50 students!! Hope this helped you a lot !!!
