The barrel holds 13.20 liters
4 would go on the x axis because it always starts like this (x, y)
The circumference would be C. 150.72 meters
Answer:
Step-by-step explanation:
Use Pythagorean Theorem: a^2+b^2=c^2 (a squared plus b squared equals c squared), where a and b are legs from the 90 degree angle and c is the opposite side of the triangle.
So for part a: a=AB=30 b=AC=30 and c=BC
a^2 +b^2 = c^2 Plug in the knowns
30^2 +30^2=c^2 Use Pemdas, Exponents first.
30^2=900 Simplify the equation
900+900=c^2 Simplify again
1800=c^2 Now to get rid of the ^2 we need to know the square root of 1800.
It is 42.426406871.........(There are more numbers in the decimal. Choose your stopping point and round) I'm going to round to the hundredths.
So, the answer to part a is 42.43 kilometers.
Now for part b. a=AD=45 b=AB=30 c=DB
Same equation
a^2 + b^2 =c^2 Plug in the knowns
45^2 + 30^2 =c^2 Simplify
2025 + 900 =c^2 Simplify
2925 =c^2 Find the square root
54.3083269 Round to the decimal place needed. I'm going with Hundredths.
Part b answer is 54.31 kilometers.

Answer: 9 miles per week</h3>
Explanation:
You divide the two values given to get 63/7 = 9.
We can think of it as if it was a ratio 63 miles: 7 weeks. Dividing both parts of that ratio by 7 will turn the "7 weeks" into "1 week".
You can check the answer by multiplying the 9 miles per week with the 7 weeks to get 9*7 = 63 miles total.
