False, you want to subtract in order to get rid of the 2x in both equations
1/4=2/8
3/8-2/8=1/8
1/8 of a hour remains on the flight. ✈️
6/6= 100%= 1.00= 6:6----------7/10=70%=0.7=7:10

Answer:
a)
b)
Step-by-step explanation:
Polar coordinates are represented as: , where 'r' is the length (or magnitude) of the line, and '' is the angle measured from the positive x-axis.
in our case:
to covert the polar to cartesian:
we can plug in our values:
the Cartesian coordinates are:
(b) to convert (x,y) = (6.06,-3.5)
we'll use the pythagoras theorem to find 'r'
the angle can be found by:
to convert radians to degrees:
writing in polar coordinates:
4 sqrt32 + 4 sqrt48
= 4 sqrt2* sqrt16 + 4 sqrt3 * sqrt16
= 16 sqrt2 + 16sqrt3
= 16(sqrt2 + sqrt3)
