Answer:

b.9210

Explanation:

circumference of circle = 2πr

So, the circumference of satellite's orbit = 2π(4400) = 8800π

GIVEN: the satellite in a circular orbit rotates around the Earth every 120 minutes.

In other words, the satellite travels 8800π every 120 minutes

So, in 40 minutes, the satellite will travel 1/3 of the 8800π mile orbit (since 40 minutes is 1/3 of 120 minute)

Distance traveled = 8800π/3

Answer:

A

Explanation:

Let's say x represents adult tickets, and y represents child tickets.

We know that 2 adult tickets, x,  and 2 child tickets, y, added together total $26. This can be written as:

2x+2y=26

We also know that 2 adult tickets, x, and 3 child tickets, y, added together total $31. This can be written as:

2x+3y=31

2x+2y=26

2x+3y=31

Therefore, choice A is correct.
