Answer:
1. yes
2. yes
3. no
4. no
5. yes
Step-by-step explanation:
The questions you're asking relate to the Triangle Inequality Theorem, which states that the two smallest sides (ex. 6 and 13) have to be of greater value than the largest side (ex. 18)
1. 6+13>18
2. 34+27>58
3. 29+9=38 (since the value of the two smallest sides are equal, it does not apply to the Triangle Inequality Theorem, and therefore won't be a triangle)
4. 12+12<25
5. 19+14>31

Power is work done per time and work done is force times distance. The power is found by multiplying the force(20N) and the distance(5m) and dividing the product by the time(5s)
(20*5)/5=20Nm/s OR 20 watts.
Therefore the power needed is 20 watts.
The percent error is by 12%
<span>The percent error is calculated by subracting the actual weight from the estimated weight and then dividing it by the actual value and multiplying it by 100% in absolute value(Which means to remove any negative sign) </span>
Answer is r = 2.5
First find the ratio of triangle like sides
11 / 4 = 2.75 ratio
Now divide 7 by ratio 2.75 = 2.5
