Answer:
In mathematics, the unknotting problem is the problem of algorithmically recognizing the unknot, given some representation of a knot, e.g., a knot diagram. There are several types of unknotting algorithms. A major unresolved challenge is to determine if the problem admits a ... First steps toward determining the computational complexity were undertaken
Step-by-step explanation:
The second one is the right answer
Answer:
-12-9--7= -14
Step-by-step explanation:
1 -12-9--7=
2 -21--7= (minus negative equals plus)
3 -21+7=14
Based on the cost of a single meter of fabric, the cost of the fabric that Joy wants is <u>$2.81</u>
Joy wants 8 feet of fabric. First convert this to meters which would be:
= 8 feet x 0.305 meter per feet
= 2.44 meters
The cost of this fabric would therefore be:
<em>= Cost per meter x Number of meters </em>
= 1.15 x 2.44
= $2.806
= $2.81
In conclusion, the cost of the fabric would be $2.81.
