It is B because you have to subtract and than you have to add
Answer:
Step-by-step explanation:
2/6(50)
because 2 of the 6 is greater than 4
with 50 rolls
The half-angle formula for tangent is:
tan(a/2) = (sin a / (1 + cos a)) = ((1 - cos a) / sin a)
Now we can plug in values:
tan(5π/8) = (sin(5π/4) / (1 + cos(5π/4)) = ((1 - cos(5π/4)) / sin(5π/4)
tan(5π/8) = (-√2/2) / (1 + (-√2/2)) = (1 - (-√2/2)) / (-√2/2)
tan(5π/8) = ((-√2/2)) / ((2 - √2)/2) = ((2 + √2)/2) / (-√2/2)
Now we can solve the first half:
(-√2/2)(2 / (2 - √2))
(-√2/2)((4 + 2√2) / 2)
(-√2/2)(2 + √2)
(-2√2 - 2)/2
-√2 - 1
tan(5pi/8) = -√2 - 1
This might be a problem considering he would have no money left considering unless I made a mistake all the numbers add up to 1,400 so considering this he won't have money to spend if he get in a situation that he needs to spend

Speed = distance / time
3 hours 45 minutes = 3.75 hours
80 = distance / 3.75
distance = 80 * 3.75 = 300 kms Answer
