Answer:
72
Step-by-step explanation:
A full rotation takes 360°. From the picture, it would take 5 rotations to achieve such full degree rotation. Hence, each bit of rotation covers 360°÷5=72°
Pyramid Surface Area = (½ * Perimeter of Base * Slant Height) + Base Area
Base perimeter = 4 * 18 = 72 inches
Base Area = 18*18 = 324 square inches
Pyramid Surface Area = (.5 * 72 * 12) + 324
Pyramid Surface Area = 432 + 324
Pyramid Surface Area = 756 square inches

Answer:
.2
Step-by-step explanation:
The probability has to sum to 1
Red + yellow + green + black + white = 1
.25+ .30 + .05 + black + white = 1
.6 + black + white =1
subtract .6 from each side
.6-.6+ black + white = 1-.6
black + white = .4
They said black and white received the same number of votes, so they will have the same probability
2 black = .4
Divide by 2
2 black /2 =.4/2
black =.2
