It looks a little less than 1/2 or 4/8, so probably 3/8 of the gas is left.
The Measures of Centrality are:
Mode, Median and Mean
From your list of answers therefore, it is the "mode".
(x-h)²+(y-k)²=r² is the equation of a circle with radius of r
so if x-h=4 and y-k=3 then
4²+3²=r²
16+9=r²
25=r²
sqrt both sides
5=r
radius is 5 units
The straight line is perpendicular to y = -3x + 4.
Therefore, the gradient of the straight line must be 3.
The equation of the straight line is y = 3x + 2.
We know that there are 3 feet in one yard. So, to find out how many yards is equivalent to 16 feet, we must divide this number by 3.
16/3 or 5 1/3
Therefore, 16 feet is equal to 16/3 or 5 1/3 yards.
Hope this helps!
