Answer:
250 miles
Step-by-step explanation:
The given distance between the house and the beach is 125 miles.
Let
miles be the distance between the house and the lunch stop.
So, at the time of the lunch stop, he already traveled
miles, the remaining distance is the distance between the lunch stop and the beach.
Let
miles be the remaining distance, so

Give that the ratio of the distance he has traveled,
, to the distance he still has to travel,
, is
,i.e








Hence, the distance traveled by Herman when he stops for lunch is 250 miles.
Answer:
The equation would be y = 2x + 3
Step-by-step explanation:
In order to solve this, we first need to find the slope of the line between (-2, 5) and (2, 3). In order to do this, we use the slope formula.
m(slope) = (y2 - y1)/(x2 - x1)
m = (3 - 5)/(2 - -2)
m = -2/4
m = -1/2
Now that we have the original line with a slope of -1/2, we can tell a perpendicular line would have a slope of 2. This is because perpendicular lines have opposite and reciprocal slopes. Now we can use that slope and the given point in point-slope form to get the answer. Be sure to solve for y.
y - y1 = m(x - x1)
y + 7 = 2(x + 5)
y + 7 = 2x + 10
y = 2x + 3
Since the trapezoid can be inscribed in a circle, that means angle B + angle D = 180 degree. Since AB is parallel to CD, then angle B + angle C = 180 degree. Therefore, angle D = angle C.
