Answer:
40 cm
Step-by-step explanation:
1 km = 10^5 cm, so 8 km = 8×10^5 cm
The map distance is 1/20,000 = 5×10^-5 of the real distance, so the map distance is ...
(5×10^-5)(8×10^5 cm) = 40 cm
Answer:
The number line is attached.
Step-by-step explanation:
The holes are filled in since they are both inclusive of the value they hold, and there are two separate lines since they are broken apart by "or".

Answer: 2 tokens.
Step-by-step explanation:
From the question, we are informed that a bag contains green tokens and black tokens and that there are 8 green tokens in the bag.

Since the green tokens is 4× the black tokens, therefore the number of black tokens in the bag will be:
= 8/4
= 2 tokens
