Answer:
the answer is 11 years
Step-by-step explanation:
if school A is graduated 50/years,
the graduated in 11 years is 550
added of graduated 1,700 in 550 is 2,250
if school B is graduated 150/years,
the graduated in 11 years is 1650
added of graduated 600 in 1650 is 2,250

Answer:
Step-by-step explanation:
Let the speed of current be x
<u>Speed of the boat in same direction as current is</u>
<u>Speed against the current is</u>
<u>Based on the given we get the equation for time</u>
<u>Solving for x</u>
- 6(10 - x) = 4(10 + x)
- 60 - 6x = 40 + 4x
- 6x + 4x = 60 - 40
- 10x = 20
- x = 2
The answer is 2 mph
Formula for 270 degree rotations:
(x,y) -----> (-y,x)
So....
p: (-3,2)----> (-2,-3)
r: (2,5)------>(-5,2)
s: (0,0) ------> (0,0)
