Answer:
1/13
Step-by-step explanation:
4 kings 52 cards in total
4/52=1/13
This problem can be solved in two ways, the long way, or the short way.
1. The long way
We know that the base of the triangle is along the x-axis, and the length of the base is 20.
The centre of mass is located at 2/3 of the distance from vertex (3,4) along the median, which cuts the base at (10,0).
Therefore the centre of mass is located at
x=3+(10-3)*2/3=23/3
y=4/3
2. The short way
It turns out that the centre of mass of a triangle sheet is located at the mean of the coordinates of the three vertices, i.e.
CG=((0+20+3)/3, (0+0+4)/3)=(23/3, 4/3) as before.
The only thing you can do with this expression is to factor a 5 out of the two terms: we have
X*y = distance
So the answer would be B.) xy miles
Answer:
B
Step-by-step explanation:
4x + 11y = 3
11y = -4x + 3
y = -4/11x + 3/11
perp. 11/4
y - 7 = 11/4(x - 2)
y - 7 = 11/4x - 11/2
y -14/2= 11/4x - 11/2
y = 11/4x + 3/2
