Answer:
no, all of the parts aren't even.
Step-by-step explanation:
the parts must be even to make a fraction so it could also be said as out of 8 equal parts, 3 are shaded but the parts arent equal so you can't.
Hope this helps! :)
Answer:
X = -9
Step-by-step explanation:
y = k X for some fixed number constant k.
-5 = k (15)
k = -5/15 = -1/3
So y = (-1/3)X
When y = 3 ---> 3 = (-1/3)X
X = -9
Answer:
x+y=68
x-y=15
Step-by-step explanation:
A "sum" means that we will be using addition, while a "difference" indicates subtraction. Anytime we have two unknown numbers we generally use "x" and "y".
We use direct proportionality:
360⁰......Pi×R² (full circle)
120⁰.......x
x=120×pi×R²/360=pi×R²/3
x=pi×4²/3=16.76mi²
A=3×pi cm², for an angle of 2×pi/3=120⁰
In a similar way we compute the area of the full circle:
360.........x
120..........3×pi
x=3×pi×360/120=9×pi=3²×pi.
Thus the radius is 3cm.
