You can take apart the word ‘perpendicular bisector’:
Perpendicular means at a right angle to the line.
So you would find the gradient of your line segment, assuming you were given two points along the line. Then find the negative reciprocal of this gradient to get your new gradient.
Bisector means cut in half.
So you find the midpoint of your line segment.
Now, substitute the midpoint coordinate and your new gradient into the equation of a straight line.
Hope this helps :D
5% out of 100% of the sales is 84 boxes
So 100 / 5 = 20
20 x 84 = 1,680 is the total amount of boxes sold
65 x2 = 130
45 x2= 90
35 x2 = 70
45 x2= 90
total = 380 feet
Answer:
10408 ft
Step-by-step explanation:
convert miles to ft
4 miles/hr * 5280 ft/ mile = 21120 ft/hr
convert hr to min
21120 ft/hr * 1hr/60 min = 352 ft/ min
multiply by 40 minutes
352 ft/min * 40 min =14080 ft
