Trevor paints 1/6 of the fence surrounding his farm each day. How many days will it take him to paint 3/4 of the fence?
VARVARA [1.3K]
To do this you have to divide 3/4 by 1/6.  To do this multiply 3/4 by the reciprocal of 1/6.  The reciprocal of 1/6 is 6/1.  So you have to multiply 3/4 and 6/1.  This will give you 18/4.  You now simplify it to 4 2/4, which can be simplified even more to 4 1/2.  It will take Trevor 4 1/2 days to paint 3/4 of the fence.  
BTW- In case you are wondering how long it'll would take him to paint the entire fence, it would be 6 days.

Use the identity x3+y3+z3−3xyz=(x+y+z)(x2+y2+z2−xy−yz−zx) to determine the value of the sum of three integers given: the sum of
fenix001 [56]

ffn

x^3+y^3+z^3-3xyz=(x+y+z)(x^2+y^2+z^2-xy-yz-zx)

x^3+y^3+z^3-3xyz=(x+y+z)(x^2+y^2+z^2-(xy+yz+zx))

the sum of their squares is 110, So x^2+y^2 + z^2= 110

the sum of their cubes is 684, so  x^3+y^3 + z^3= 684

the product of the three integers is 210, so xyz= 210

the sum of any two products (xy+yz+zx) is 107

Now we plug in all the values in the identity

x^3+y^3+z^3-3xyz=(x+y+z)(x^2+y^2+z^2-(xy+yz+zx))

684 - 3(210) = (x+y+z)(110-107)

684 - 630 = (x+y+z)(3)

54 = 3(x+y+z)

Divide by 3 on both sides

18 = x+y+z

the value of the sum of three integers is 18

( pie over 2 - x)

Because we know that cos (pie over 2 ) =0 and sin (pie over 2) = 1
So we get
Sin (pie over 2 -x) =cos(x)
