First you want to organize the numbers in order to find the median so it should look like this: 14, 28, 42, 56. Then you want to find the one in the middle. But oh wait there are TWO in the middle so add 42 and 28 up 70 then divide it by 2 which equals your median of 35.
Option A because it’s the most effective
<span>D. (x - 1)2 + (y - 2)2 = 16
Remember the circle formula: (x-h)^2 +(y-k)^2 = r^2</span>
Point that also lies on the line is (-3, -3)
Given that one hose can fill a pool in 90 min and another can fill the pool in 60 minutes, to get how long the 2 hoses will take to fill the pool given that they are running together, we shall simply get the GCF of the times takes by the hoses, thus we shall have:
Multiples of 60 are
2,2,3,5
Multiples of 90
2,3,3,5
thus the GCF is: 2×3×5=30
Thus the two hoses working together will take 30 min
