Answer:
9.33 seconds
60.67 meters
Step-by-step explanation:
A worker with a speed of 3.0 m/s with respect to a car, starts to walk from one end of the car to the other in the direction of motion of the car.
As the car is 28 m long, then the worker will reach the other end of the car in
seconds. (Answer)
Now, the car is moving with a speed of 6.5 m/s and in the time of 9.33 seconds, it will move by
meters. (Answer)
The answer is going to be
x= 2,0
y= 0, -6
Answer:
140
Step-by-step explanation:
Consider a square for just a second. It has 4 angles each of 90 degrees. The total number of degrees in a square is 4 * 90 = 360.
It should be at least an appeal to your intuition to say that a quadrilateral has a total of 360 degrees.
Therefore the ratio you have been given must have 4 angles that add to 360.
2x + 3x + 6x + 7x = 360
18x =360
x = 20
So the 4 angles are
2* 20 = 40
3*20 = 60
6*20 = 120
7*20 = 140
Total 360
The largest angle is 140
(2 x 100,000) + (7 x 10,000) + (9 x 100) + (5 x 10) = 270,950
