Answer:
720
Step-by-step explanation:
interior angles of a hexagon is 720
1*2*0.2 = 0.4
Pipe drains 0.4m3 in 30min
Volume of tank = 0.5 * (1.4 + 0.6) * 2 * 1 = 2m3
Time taken = 2/0.4 * 30 = 150min
Answer:
a(217)=638
Step-by-step explanation:
a(n) = a +(n-1)d
a=-1
d=-7+10=-4+7=3
a(n) = -10 +(n-1)3
a(217) = -10 +(217-1)3
= -10+648
=638
