False because a number is rational if we can write it as a fraction where the top number of and bottom number are both whole numbers but irrational numbers is any number that is not rational. It is a number that cannot be written as a ratio of two integers(or cannot be expressed as a fraction)
Answer:
(a) 680 km
(b) 680000 m
Step-by-step explanation:
(a) Distance run by hunter every day = 6.8 km
Total number of days under consideration = 100
So the total distance covered by the hunter = ![\[6.8 * 100\] ](https://tex.z-dn.net/?f=%5C%5B6.8%20%2A%20100%5C%5D%0A)
= 680 km
The hunter ran 680 km in the last 100 days.
(b) Converting this value to meters:
1 km = 1000 m
=> 680 km = 680 * 1000 m
= 680000 m
The equivalent distance run by the hunter when converted to meters is 680000 meters.
Answer:
2 students failed the test.
Step-by-step explanation:
There are 40 students and 95% passed. 95% is also equal to 0.95. Since we are looking for the students who failed, subtract 1.00 - 0.95. You get 0.05. The percentage of students who failed is 5%. Multiply 0.05 times 40 to get 2. This is the amount of students who failed.
