Answer: The fraction would be 0.53.
Step-by-step explanation:
Since we have given that

where, A is the constant initial production rate
t is the time.
For 98 years, the production rate in motorcycles per year would be

For 13 years, the production rate in motorcycles per year would be

So, the fraction of their total production was built during the last 13 years would be

Hence, the fraction would be 0.53.
Answer:
The number 10/7 is a rational number, which means it can be expressed as a fraction. Also, if we divide it would give a decimal infinite periodical number, which means it has a pattern on its decimal numbers.
On the other hand, the square root of 2 is irrational number, that means it can't be expressed as a fraction, because its decimal numbers don't have any pattern at all.
So, Mai's brother can see these type of numbers as crazy (irrational numbers) and sane (rational numbers).
At last, another important characteristic to shows that they aren't equal is that they don't have the exactly decimal numbers.
Answer:
The three iron rods cannot be placed together to form a triangle.
Step-by-step explanation:
We have been given that James has three iron rods. Rod A is 3 feet long, rod B is 8 feet long, and rod C is 13 feet long. We are asked to determine whether the lengths of all rods can be used to form a triangle.
We will use triangle inequality theorem to solve our given problem.
Triangle inequality theorem states that sum of two sides of a triangle must be greater than 3rd side.
Using triangle inequality theorem, we will get inequalities as:




We can see that our 2nd inequality is not true because 11 is not greater than 13.
Since sum of two sides is not greater than 3rd side, therefore, the three iron rods cannot be placed together to form a triangle.
2 49/100 in decimal form is 2.49 because a decimal in the one hundredths would be like this: 0.09 or 0.49, and the two is a whole number, so it would go before the decimal like this: 2.09 or 2.49.
Hope this helped:):)
