Answer:
1 /25.
Step-by-step explanation:
Using order of operations, we perform the multiplication first:
1/5 - 2/15 × 1/5 - 2/15
= 1/5 - 2/75 - 2/15 LCD of 5, 15 and 75 is 75 so we have:
15/75 - 2/75 - 10/75
= 13/75 - 10/75 = 3/75
= 1 /25 (answer).

Answer: 1150 turns
Step-by-step explanation: radius of wheel is 0,9 m
In one turn wheel moves 2·pi·0,9 m = 5,652 m
You divide 6500 m : 6,652 m = 1150
Hypothesis (p): A polygon is a square
Conclusion: (q): It is a rectangle
Inverse: q → p <em>If a polygon is a rectangle, then it is a square</em>
Converse: ~p → ~q <em>If a polygon is not a square, then it is not a rectangle.</em>
Contrapositive: ~q → ~p <em>If a polygon is not a rectangle, then it is not a square</em>
