More than suggests addition.
The ellipse will be inscribed in the rectangle.
Because the rectangle measures 8 mi by 6 mi, the ellipse has
a = 8/2 = 4 mi (major axis)
b = 6/2 = 3 mi (minor axis)
The equation for the ellipse is
x^2/a^2 + y^2/b^2 = 1
That is
x^2/4^2 + y^2/3^2 = 1
x^2/16 + y^2/9 = 1
Answer:
x^2/16 + y^2/9 = 1
T= total
<span>Money spent is: </span>
48+ 1/3 (T-48) = 1/2 T
One equation for one unknown, solve:
48 + 1/3 T -1/3*48= 1/2 T
48 - 16 =1/2 T- 1/3 T
32= 1/6 T
T= 6*32
<span>T=192
</span>192-48=144 money left after watch
1/3*144=48 third of leftover, spent on pen
<span>144-48=96 left which is half of 192. </span>
Answer:
Below.
Step-by-step explanation:
(-3, 9) - Quadrant II.
(6, -6) - Quadrant IV.
(0, -1 1/2) - x-axis 0, y-axis -1/1/2
