180° because it is half of a full circle(360°)
Answer:
x = 
Step-by-step explanation:
Given
8x + 9y = gx + 5z ( subtract gx from both sides )
8x - gx + 9y = 5z ( subtract 9y from both sides )
8x - gx = 5z - 9y ( factor out x on the left side )
x(8 - g) = 5z - 9y ← divide both sides by (8 - g)
x = 
Answer:
0.196
Step-by-step explanation:
Let :
Expresso drink = A
Plain coffee = B
Food = F
P(A) = 0.56
P(B) = 0.44
P(F) = 0.40
P(F|A) = 0.35
P(F|B) = 0.30
Probability that a customer purchases a specialty expresso coffee and a food item :
P(F|A) =. P(F n A) / P(A)
P(F n A) = P(F|A) * P(A)
P(F n A) = 0.35 * 0.56
P(F n A) = 0.196
Answer: The perimeter is 20 cm
Step-by-step explanation: The top and bottom are same length, so 6+6, and the sides are the same length, so 4+4 don’t forget it’s cm and it becomes 20 cm.
PERIMITER = ADDING ALL SIDES
AREA = MULTIPLYING
