2(p+w)=240
p+w=120
w=120-p, we will use this value for w below...
2(p-w)=210
p-w=105, now use the w from earlier...
p-120+p=105
2p-120=105
2p=225
p=112.5 mph (and wind is 7.5 mph)
Answer:
5 5/7 km
Step-by-step explanation:
We assume the length of thread is proportional to the number of boxes of shirts. If L is the thread length required, then that assumption means
... L/(6 boxes) = (3 1/3 km)/(3 1/2 boxes)
Multiplying the equation by (6 boxes), we get
... L = (3 1/3 km)(6/(3 1/2)) = (10/3 km)(6/(7/2))
... = (10/3 km)(12/7) = 40/7 km = 5 5/7 km
They are both an average calculation to the nearest whole number.
Yo sup??
By the formula
X=l/r
l=rX
Where r is the radius
l is the lenght
X is the angle
Plugging in the values we get
l=π/3*1
=π/3 units
Therefore the correct answer is option C
Hope this helps
