Answer:
Simply substract 0.39 from 0.54 = 0.15
Therefore the carpenter is left with 0.5 metre of wood.
Answer: (s for small, l for large) s=15.25 kg, l=18.5 kg.
Explanation: We need a system of equation to find the two weights of both boxes.
We can use 4s+8l=209 and 2s+3l=86.
If we multiply the second equation by -2 (for elimination), we will have -4s-6l=-172.
Combing the first equation with this new one gives us 2l=37, where dividing by 2 gives us l=18.5 kg.
We can plug 18.5 into any of the two original equations to find s.
4s+8*18.5=209
4s+148=209
4s=61
s=15.25 kg
Answer:
15 pi
Step-by-step explanation:
The circumference of the circle is given by
C = pi * d
C = pi *18
We are subtracting part of the circumference that covers 60 degrees
The entire circle is 360 degrees
60/360 = 1/6
We are subtracting 1/6 of the circumference
1/6 *18pi = 3pi
We have 18pi and subtract 3pi = 15pi
The dark shaded arc is 15pi
3x^2+y (there is no common factor to further simplify this)
