For time-speed-distance problems, you use the relationship
.. speed = distance/time
in any of its various forms.
The distance traveled at A mph is
.. distance = speed * time
.. distance = A*3
The time required for the rest of the journey is
.. time = distance / speed
.. time = (C -3A)/B
The the total time required to travel C miles is the 3 hours for the first part plus the time for the rest of the journey.
.. total journey time = 3 + (C -3A)B . . . . . hours
7×65 7×(60+5)
(7×60) (7×5)
(420)+(35)
The answer is 455
Answer:
(2,9)
Step-by-step explanation:
Answer:
(x + 2)^2 + (y - 3)^2 = 9
Step-by-step explanation:
The standard formula for the equation of a circle would be:
(x - h)^2 + (y - k)^2 = r^2
where (h, k) is the center and r is the radius.
From the picture, the center is given to be (-2, 3) and by counting the squares, we can say the radius is 3. We can plugs these values into the equation.
(x + 2)^2 + (y - 3)^2 = 9
