You take a train away from Bangkok at 1:50 a. m. on Wednesday. You ride the train for 16 hours and 40 minutes, at which point you arrive in Vladivostok at 9:30 p. m. on Wednesday, local time. How does Vladivostok’s time zone relate to Bangkok’s time zone? a.
Vladivostok is three hours ahead of Bangkok.
b.
Vladivostok is nine hours behind Bangkok.
c.
Vladivostok is fifteen hours behind Bangkok.
d.
Vladivostok is twenty-one hours ahead of Bangkok.

a.

Vladivostok is three hours ahead of Bangkok.

Step-by-step explanation:

Time the train left Bangkok is 1:50am

It traveled for 16 hours 40 minutes.

If the train was to be in Bangkok.

The Time Will be 1+16 hours then 50+40 minutes

Which is 17 hours + 1 hour 30 minutes

Which is 18 hours and 30 minutes

And 18 hours = 6:00 pm

So if it was in Bangkok the time with be 6:30 pm

But in Vladivostok, it was 9:30 pm

It's clear that Vladivostok time is faster by 3 hours

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

point a is the center of the circle that passes through points e, f, and g and the center of the circle that passes through points x, y, and z.
