Geometric probability PLEASE HELP!

Mathematics
1 answer:
kap26 [50]3 years ago
8 0

Answer:

Step-by-step explanation:

The red sections are sectors of the circle. We need that area. We'll find one then multiply it by 2, since they're both the same.

A_s=\frac{60}{360}\pi (4)^2\\A_s=\frac{1}{6}\pi (16)\\A_s=8.377and now we multiply it by 2 to get the red area:

A_s=16.754

And now the area of the circle:

A_c=\pi (4)^2\\A_c=16\pi\\A_c=50.265 and now divide to get the percentage:

\frac{16.754}{50.265}*100= 33.3%

If y varies inversely as x, and y=20 as x=3, find y for the x value 4
Ratling [72]
\bf \qquad \qquad \textit{inverse proportional variation}\\\\
\textit{\underline{y} varies inversely with \underline{x}}\qquad \qquad  y=\cfrac{k}{x}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad  variation
\end{array}\\\\
-------------------------------\\\\
\begin{cases}
y=20\\
x=3
\end{cases}\implies 20=\cfrac{k}{3}\implies 20\cdot 3=k\implies 60=k
\\\\\\
thus\qquad \boxed{y=\cfrac{60}{x}}\\\\
-------------------------------\\\\
now\qquad x=4\qquad y=\cfrac{60}{4}

What are the solutions to the quadratic equation 5x2 + 60x = 0?
Reptile [31]

Answer:

It's A.

Step-by-step explanation:

5x2 + 60x = 0

5x is the GCF so:

5x(x + 12 ) = 0

5x = 0, x + 12 = 0

x =0, x = -12.
