1g I think am not sure u didn't give a lot of information on this problem
Part 2 is 12.5 cm represents 5km
I worked this out by doing a ratio
5cm=2km
?cm=5km
you have to do 2 times 2.5 to get 5km so you do 5 times 2.5 to get 12.5cm
so the answer is that 12.5cm
The Answer is 6.3245553203368.
Also if you can please answer my recent question.
That will Mean so much.
Answer: 90.82%
Step-by-step explanation:
Given : The distribution of the amount of a certain brand of soda in 16 OZ bottles is approximately normal .
Mean : 
Standard deviation: 
Let X be the random variable that represents the amount of soda in bottles.
Formula for z-score : 
Z-score for 16 oz: 
Using the standard normal z-distribution table , the probability that the soda bottles that contain more than the 16 OZ is given by :_
Hence, the percentage of the soda bottles that contain more than the 16 OZ advertised is 90.82% .
That is sort of a vague question, but in general you can:
1. Analyze the problem to identify:
a) What type of problem it is (word problem, algebra,etc.)
b) What the question is asking you (you must understand the question to do it)
2. Draw visuals (ex. venn diagram), graphs and tables to help you start the question
3. Create a plan to solve the question. For example the formulas and materials you need.
4. Try to solve the problem. This can be achieved in many ways.
5. If you are having problems, refer to the internet or ask a friend, teacher, parent or tutor.
