Answer: 1/6
Step-by-step explanation: ok, so he had mowed 1/3 of a field in 2 hours. Take 1/3 and divide by 2 hours to get 1/6
The required plane Π contains the line
L: (-1,1,2)+t(7,6,2)
means that Π is perpendicular to the direction vector of the line L, namely
vl=<7,6,2>
It is also required that Π be perpendicular to the plane
Π 1 : 5y-7z+8=0
means that Π is also perpendicular to the normal vector of the given plane, vp=<0,5,-7>.
Thus the normal vector of the required plane, Π can be obtained by the cross product of vl and vp, or vl x vp:
i j k
7 6 2
0 5 -7
=<-42-10, 0+49, 35-0>
=<-52, 49, 35>
which is the normal vector of Π
Since Π has to contain the line, it must pass through the point (-1,1,2), so the equation of the plane is
Π : -52(x-(-1))+49(y-1)+35(z-2)=0
=>
Π : -52x+49y+35z = 171
Check that normal vector of plane is orthogonal to line direction vector
<-52,49,35>.<7,6,2>
=-364+294+70
=0 ok

its suppose to be a fraction hope it helps please mark brainliest
Respuesta:
dieciséis
Explicación paso a paso:
100-ab - - - - (1)
100-ba - - - - (2)
Sumando (1) y (2) sumas hasta 24
100-ab + 100-ba = 24
100 + 100 - ab - ba = 24
200- (10a + b) - (10b + a) = 24
200-10a-b-10b-a = 24
200-24 = 10a + 10b + b + a
176 = 11a + 11b
176 = 11 (a + b)
176/11 = a + b
16 = (a + b)
Greetings!Solve for x.

Multply both sides by
8 to get rid of the fraction.


Add
-11 to both sides.
The Answer Is:

Hope this helps.
