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".
The radius is half of the diameter, and half of 9 is 4.5. That is your answer. Hope this helps! Have a nice night.
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.
We are further told that the ratio of green tokens to black tokens is 4 for every 1.
Since the green tokens is 4× the black tokens, therefore the number of black tokens in the bag will be:
= 8/4
= 2 tokens
