La respuesta es B a+10b+6c=62
Answer:
Cookie=0.5, Apple=1.5, sandwich= 3
Step-by-step explanation:
Lets say cookie = x, then sandwich = 6x since sandwich is 6 times more expensive, apple = 3x. function: 6x+3x+x =5
10x=5
x=0.5
I think it is D. All the boxes shaded adds up to 57 which is 0.57 in this problem due to the grid being one hundred boxes. Then 19 is being subtracted so its 0.19. 0.57-0.19
Answer:
x = π/2 + nπ or x = (2/3 π + 2nπ) or x = (4/3 π + 2nπ)
Step-by-step explanation:
1 + cosx + cos2x=0
1+cosx+(2cos²x -1) = cosx + 2cos²x = cosx (1 + 2cosx) = 0
cosx = 0
x = 90° (π/2) or (90+180) or (90+180x2) .... i.e π/2 + nπ
or 1 + 2cosx = 0
cosx = -1/2
x = 120° or 240° (2/3 π or 4/3 π) or (120 + 360 : 2/3 π + 2π) (120 + 2 * 360)
.... i.e. (2/3 π + 2nπ)
or (240 + 360 : 4/3 π + 2π) (240 + 2 * 360) .... i.e. (4/3 π + 2nπ)
