Answer:
12.5%
Step-by-step explanation:
105 is what percent of 120?
you can use this proportion:
if/of = %/100
in this problem:
is = 105
of = 120
'what percent' = p/100
105/120 = p/100
cross-multiply to get:
120p = 10500
p = 10500/120
p = 87.5
So the electrician used 87.5%, out of 100%, meaning 12.5% went unused
Answer:
1) line segment
2) square-root of 13.
3) plane F
4) Ray
5) I think the wrong image is attached, but a point would just be a dot, a line would have one dot then an arrow on the other end, an angle would be 2 lines connected with an emphasis on what's going on in between the 2 lines, a line segment is 2 dots on both ends of a line.
6)H N K I
7) (2,-8)
8) line p
9) (-2, 7)
Step-by-step explanation:
For the distance between 2 points, do (x2-x1)^2+(y2-y1)^2 then take the square root of that.
For naming a plane, as long as it is an uppercase cursive letter it is a plane.
Rays are lines without the dot on the end.
Collinear points are points that lie on the same line.
Midpoint method is finding the average between the x coordinates then the y coordinates, so think (x1+x2)/2, (y1+y2)/2, but this can be confusing with negative distances, so just think of it as on a number line, from -1 to -3 they are 4 apart, so the average between them is -2.
I think the answer is yes
I don’t think this would exist because it would be only on the -2 point.
Answer:
(-3,-2), (-1,-2), (1,-2)
Step-by-step explanation:
Each point on the plane is of the form (x,y). let's see which points satisfy the inequality 
a)
, then (-3,-2) satisfies the inequality.
b)
, then (-2,1) doesn't satisfy the inequality
c)
, then (-1,-2) satisfies the inequality.
d)
, then (-1,2) doesn't satisfy the inequality.
e)
, then (1,-2) satisfies the inequality.
