Hey there!

$\bold{1\frac{1}{5}-\frac{3}{4}}$

$\bold{1\frac{1}{5}\rightarrow1\times5+1\rightarrow\frac{6}{5}}$
$\bold{\frac{6}{5}-\frac{3}{4}}$
$\bold{6+3=9}$
$\bold{9\rightarrow numerator}$
$\bold{5\times4=20}$
$\bold{20\rightarrow denominator}$
$\boxed{\boxed{\bold{Answer:\frac{9}{20}}}}\checkmark$

Good luck on your assignment and enjoy your day!

If a+b+c=0 for a,b,c then prove a²/bc+b²/ca+c²/ab=3.

Ierofanga [76]

According to the identity if a+b+c=0
then a3+b3+c3=3abc
a3+b3+c3/abc=3
a2*a/bc*a+b2*b/ca*b+c2*c/ab*c=3
cancel a,b,c in all the fraction then you get
<span>a²/bc+b²/ca+c²/ab=3.
</span>hence proved

Brook makes this conjecture: Because the angles are equal, the proportion of area of each sector relative to the area of the giv

AnnZ [28]

Answer:

The Brooks conjecture is true as the proportion of the area of a sector to the area of a circle is only dependent on the angle.

Step-by-step explanation:

The area of a sector for a radius r and an angle θ is given as

$\Delta Sector=\dfrac{1}{2}r^2\theta$

Whereas the area of a circle for a radius r is given as

$\Delta Circle=\pi r^2$

Now the ratio is given as

$\dfrac{\Delta Sector}{\Delta Circle}=\dfrac{\dfrac{1}{2}r^2\theta}{\pi r^2}$

Here as r is the radius of the circle and it is the same therefore the above ratio is simplified to

$\dfrac{\Delta Sector}{\Delta Circle}=\dfrac{\theta}{2\pi }$

Here as π is constant the only variable here is θ. Thus according to Brooks conjecture when the angles are equal, the proportion of area of each sector relative to the area of the given circle is also equal is true.
