Answer:
You didn't send the pool dimensions ill answer it when u do
Step-by-step explanation:
Speed traveling west = x - 10 km /hr
275 / ( x-10) - 300 / x = 1/2
275 *2x - 300 (x-10)*2 = ( x-10) *x
550x - 600x +6000 = x^2 -10x
x^2 +40x - 6000 = 0
( x -60) ( x+100) = 0
x = 60
ANSWER East = 60 km/ hr West = 50 km /hr
CHECK
300 /60 = 5 hours
275 /50 = 5.5 hours
Answer:
There is a 2.7% chance that a particular death is due to an automobile accident?
Step-by-step explanation:
Automobile _____ 24 deaths
Cancer _________182 deaths

Probability = 0.027
Probability = 2.7%
Answer:
(2,-2)
Step-by-step explanation:
y=-4x+6
y=3x-8
plug the y's in for each other to get:
-4x+6=3x-8 <----- solve from there
+8 +8
-4x+14=3x
+4x +4x
14=7x
/7 /7
x=2
now plug the x in to get y (in any problem)
y=3(2)-8
y=6-8
y=-2
<em>(2,-2)</em>
Divide 754 by 13 and you get 58
Now multiply by 9 and you get 522 miles.
