A: 39 over 50000
b: 20003 over 10000
The diameter is 30 cm, therefore the radius is 15 cm. The circumference of the tire is found by using the formula C = 2πr. C ≈ 2(3.14)(15) ≈ 94.2 cm. 5 km = 500,000 cm (5 x 1000 x 100). 500,000 ÷ 94.2 ≈ 5307.86 or about 5300 times (revolutions). (using π, instead of 3.14, I got 5305.16 revolutions)
Answer:
670,000
Step-by-step explanation:
5 or more, raise the score.
4 or less, let it rest.
5 rounds 0 up to 1
672,910
1 doesn't change the 9
672,900
9 rounds 2 up to 3
673,000
3 doesn't change the 7
670,000
So you can look at the first digit of each number: you have a 3, 2, 3. You know 2 is less than three. So 2,965,006 is the smallest number. You had two numbers where 3 was the first digit, so you look at the next number: a 5 and 2. 2 is smaller than 5, so 3,261,636 will be the next smallest.
Overall, least to greatest is:
2,965,006; 3,261,636; and finally 3,516,235 :)
Just plug in a calculator 336/7 and you should get a non decimal answer.
