Answer:
The coordinates of point X are (-11/2, 5/2)
Step-by-step explanation:
To find the coordinates of X , we shall apply the midpoint formula;
Mathematically, that would be;
(x , y) = (x1 + x2)/2 , (y1 + y2)/2
From the question
x1 = -3 , x2 = -8
y1 = 1 , y2 = 4
So substituting these values, we have;
(x ,y) = (-3-8)/2, (1 + 4)/2
(x ,y) = -11/2, 5/2
Answer:
- 3 hours
- 1 hour 45 minutes
- 300 miles
Step-by-step explanation:
1. The trains are moving toward each other at a total speed of 50 +20 = 70 miles per hour. Together, they cover the 210 mile distance in ...
time = distance/speed
time = 210 mi/(70 mi/h) = 3 h
The trains collide after 3 hours.
__
2. The fly is closing with the freight train at a speed of 100 +20 = 120 miles per hour. Together, the fly and the train cover the initial 210 mile distance in ...
(210 mi)/(120 mi/h) = 7/4 h = 1 hour 45 minutes
The fly first meets the oncoming freight train after 1 h 45 min.
__
3. The fly is flying for all three hours before the trains collide, so, at 100 miles per hour, will fly 300 miles.
21.20 would be the total with tax
the taxes would equal $1.20
Honestly to explain it I put it into a calculator.. sorry :)
I put in 6% of 20 then add it to the $20
