The answer is 5 minutes. Simply divide 60 by 12.
Answer:
Mid-point: 
Equation: 
Step-by-step explanation:
To find the mid-point of AB, simply add up their x and y coordinates and divide by 2 respectively to find their middle point.



To find the perpendicular slope that passes through the mid-point, we need to know the slope between AB first.
Slope of AB:
=
=
= 
Multiplying slopes that are perpendicular with each other always results in -1.


By the point slope form:

Plug in the coordinates of the mid-point:

Equation: 
Answer:
The answer is -15.75 because 4= -16= -79 you have to turn 16 positive so add 16 to -79 to get -63 then divide by 4 to get the answer -15.75.
Answer:
$38.84
Step-by-step explanation:
8.6% of $42.50
42.50 × 8.6/100 = 3.655 or 3.66
before tax
$42.50 - $3.66 = $38.84
