Answer:
x=50
Step-by-step explanation:
To find the angle on the bottom left you would subtract 180-149 and get 31.
Then you would add 31 and 99 to get 130.
Then subtract 180-130 to get x=50 because all triangles equal 180 if you add all of the angles together.
Answer:

The answer would be B
In the thing above it says she earns 100 each week PLUS 15 each sale she makes there for that being commission
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
Step-by-step explanation:
The next three numbers in the sequence are 121, 144, and 169
