If a line is perpendicular to other his slopes are the opposite inverse of each other
So, if y = -2x - 4 we have the slope of -2, so the slope of the other line will be the opposite inverse which means
opposite of -2 = 2
inverse of 2 = 1/2
So our slope is 1/2
(y - yo) = m.(x - xo)
(y - 4) = 1/2.(x - 3)
y - 4 = x/2 - 3/2
y = x/2 - 3/2 + 4
y = x/2 + 5/2
length = 8ft
height = 4 in
width = w ft --> u looking for this
convert in to ft for the height:
4 in (1 ft / 12 in) = 1/3 ft
You know that:
1 cubic yard = $ 98
? cubic yard = $58.07
Solve for ? cubic yard:
? cubic yard = 58.07/98 = 0.592551
convert this in cubic feet:
1 yard = 3 feet
0.59255 cubic yard (27 cubic ft/1 cubic yard) = 15.99887755 cubic ft
Now solve for the width:
length x width x height = ? cubic ft.
width = ? cubic ft / (length x height) =15.99887755 cubic ft/[(8ft)(1/3 ft )] = 5.999579082 ft
approx 6 ft
Jose lost 120
50-120= -70
Ling lost 80
50-80= -30
Ling won because he had -30 while Jose had -70
