Answer:
24
Step-by-step explanation
The question just ask to subtract 18 from 42 which would = 24.
L = 2 W
B = L x W = 2 W²
Side Area = 2 W H + 2 L H = 2 H ( W + L ) = 6 H W
V = 2 W² H = 10
H = 5 / W²
Cost = 15 * 2 W² + 9 * 5/W
= 30 W² + 270/ W
C ` = 60 W - 270 / W²
= ( 60 W² - 270 ) / W² = 0
60 W² = 270
W ² = 270 : 60
W² = 4.5
W = √ 4.5 = 2.12
Cost (min) = 15 * 2 * 4.5 + 30 / 2.12 = 135 + 14.15 = $149.15
Answer: The cost of materials for the cheapest such container is $149.15.
The answer is D.
Hope this helps :)
Answer:
18/(-3)=-6 . (-18)/(-3)=6 . (-15)(-2)=30. 15(2)=30. 12(-4)=-48
Step-by-step explanation:
18 divided by -3 is -is -6. -18 divided by -3 is 6. -15 times -2 is 30 . 15 times 2 is 30. 12 times -4 is -48 .
