14 hours.
Work backwards. From travel, getting ready and sleep he needs 9.5 hours. From 11am to 10:30am is 23.5 hours. Subtracting the two you get 14 hours.
Answer:
D) (-2, -3)(-4, -3)(-2, -9); because corresponding pairs of sides and corresponding pairs of angles are congruent
Step-by-step explanation:
For triangles to be congruent, it is not enough that corresponding angles are congruent. In addition, there must be at least one pair of corresponding sides that are congruent. (Then all pairs will be congruent.)
The points listed in choices B and D are points that form a right triangle with leg lengths 2 and 6. However, choice B only refers to the angle measures, and not the sides. Choice D is the correct one.
Answer she used 4.5 for each bag.
Step-by-step explanation:
Since the given line

has slope

The equation of the line perpendicular to it must have a slope which is the negative reciprocal of ,

The slope of the perpendicular line

Using the slope intercept form,

We substitute

This implies that,

Since

lies on this line , it must satisfy its equation.
That is

This implies that



The line therefore has equation,
