the distance between two cities is 400,000 meters If the train travels at a speed of 80 kilometers per hour, how long will it take the train to travel from one city to the next?

Answer:

7.5

Step-by-step explanation:

0.2(6r-5)                 =8              Distribute.

0.2(6r)-0.2 (5)         =8              Simplify.

1.2r−1                       =8              Add 1 to each side.

1.2r                          =9              Divide each side by 1.2.

1.2r/1.2                     =9/1.2        Simplify.

r                               =7.5

Hello!

To find our answer , we just multiply each side length.

7(6)=42

42(2)=84

Therefore, our answer is A) 84 ft³

I hope this helps!

The answer is 84yd3 if you have more questions look it up on a volume calculator

Answer:

The correct answer is C. All integers where n ≥ 1

Final answer:

The domain for n in the given arithmetic sequence is the set of positive integers.

Explanation:

The domain of the arithmetic sequence an = −4 + 4(n − 1) is the set of all possible values for n. In this case, since n represents the position in the sequence, it can only take on positive integer values starting from 1. Therefore, the domain for n is the set of all positive integers: {1, 2, 3, 4, ...}.
