Answer:
Two points are collinear when they lie on the same line. Points are collinear but not lines. Rather when two lines lie on the same plane we say they are coplanar.
Hence, line AB and CD are NOT collinear, so they are noncollinear and they are coplanar.
Two or more lines are said to be intersecting, when the lines meet at some point, when lines are not intersecting they are said to be parallel.
Recall that one of the properties of a rectangle is that opposite sides are parallel.
Notice that line AB and CB are the opposite sides of the rectangle ABCD.
Thus, line AB and CD are not intersecting but are parallel.
Therefore, the terms that best describe lines AB and CD are
parallel
noncollinear
coplanar
Step-by-step explanation:
I'm guessing 90 hours because if you add their hours together it'll be 180 if they work together it'll be like half the time which is 90
Answer:
Part a) 
Part b) The coordinates of the point are 
Step-by-step explanation:
Part a) Find the equation representing the ladder
we have the ordered pairs
(0,4) and (2,0)
Find the slope
Find the equation of the line in slope intercept form
we have
substitute
Part b) A square box just fits under the ladder.Find the coordinates of the point where the box touches the ladder.
If the box is a square
the x-coordinate of the point where the box touches the ladder must be equal to the y-coordinate
x=y
substitute
therefore
The coordinates of the point are
Answer:
Different timings for drinking before the run can decrease the accuracy of the outcome.
But different drinks for different people before a single run can ruin the experiment causing usless result. Effect of different sports drink on athletes can not be measured accurately.
