Answer:
w = w L = 2w h = h
Volume: V = Lwh
10 = (2w)(w)(h)
10 = 2hw^2
h = 5/w^2
Cost: C(w) = 10(Lw) + 2[6(hw)] + 2[6(hL)])
= 10(2w^2) + 2(6(hw)) + 2(6(h)(2w)
= 20w^2 + 2[6w(5/w^2)] + 2[12w(5/w^2)]
= 20w^2 + 60/w + 120/w
= 20 w^2 + 180w^(-1)
C'(w) = 40w - 180w^(-2)
Critical numbers:
(40w^3 - 180)/w^2 = 0
40w^3 -180 = 0
40w^3 = 180
w^3 = 9/2
w = 1.65 m
L = 3.30 m
h = 1.84 m
Cost: C = 10(Lw) + 2[6(hw)] + 2[6(hL)])
= 10(3.30)(1.65) + 2[6(1.84)(1.65)] + 2[6(1.84)(3.30)])
= $165.75 cheapest cost

Answer:
14 gm
Step-by-step explanation:
34 minutes is TWO half lives 1/2 * 1/2 = 1/4 will be left

Answer:
There is no following, we have data of all the people
Step-by-step explanation:
There where Sixty-five salespersons asked and the if we add all the persons that where asked it is the same. So there is no following
Fourteen people answered that they generally sell two cars; 14
nineteen generally sell three cars; 19
twelve generally sell four cars; 12
nine generally sell five cars; 9
eleven generally sell six cars 11
Adding 14+19+12+9+11=65 persons
Answer:
10
Step-by-step explanation:
the sudents were put in 10 equal groups
10x6=60
Your answer would be the first option: has all sides congruent and all angles congruent.
This is because although this does apply to squares, it can also apply to shapes like a rhombus, as it sits not guarantee that those congruent angles are 90° like they must be for the shape to be a square.
I hope this helps!
