IT SHOULD BE 9:26 BECAUSE TIME STARTS OVER AT 12:59 SO IF YOU COUNT 1,2,3,4,5,6,7,8,9 THEN ADD 26 IT IS <em><u>9:26</u></em>
You replace x by 18 so it becomes f(18)=1.50×18+12.50 and that should give you 39.50
Answer:
There are four basic properties of numbers: commutative, associative, distributive, and identity.
I hope this helped :)
Clockwise moments = Anticlockwise moments
Call the force you apply horizontally to the top left side of the square N.
W = 510 acting from the centre as the mass is distributed evenly.
Take moments about a pivot, in this case the bottom right corner is the pivot.
The clockwise moment is N and the anticlockwise moment is W.
N*x*sqrt(2) = 510*x/2
205x =Nx*sqrt(2)
205 = N*sqrt(2)
N = 205/sqrt(2)
