IM SO LOST PLEASE HELP

LiRa [457]

Check the picture below.

$\bf \textit{lateral area of a cone}\\\\
LA=\pi r\stackrel{slant-height}{\sqrt{r^2+h^2}}~~
\begin{cases}
LA=539\pi \\
r=49
\end{cases}\implies 539\pi =\pi 49\sqrt{r^2+h^2}
\\\\\\
\cfrac{539\pi }{49\pi }=\sqrt{r^2+h^2}\implies 11=\sqrt{r^2+h^2}$

A bag contains 6 red marbles, 2 white marbles, and 1 gray marble.You randomly pick out a marble,record its color,and put it back

Dominik [7]

You should expect 5. There is one grey marble out of 9 total, and that can be expressed as 1/9. Since you repeat it 45 times, it's 1/9 45 times, or 1/9(45).

$\frac{1}{9} * \frac{45}{1}$

1*45 is 45

9*1 is 9.

45/9 is 5.

Justify why a / b x b / c x c /d x d / e is equal to a /e when B C D and E are not zero

Maru [420]

a/b * b/c * c/d * d/e is equal to a/e provided that b, c, d, and e are not zero

PROVE

a/b * b/c * c/d * d/e

= (a/b *b/c) * (c/d * d/e)

= ab/bc * (c/d * d/e)

= a/c * (c/d * d/e)

= a/c * (cd/de)

= a/c * c/e

= ac/ce

= a/e

Therefore, a/b * b/c * c/d * d/e is equal to a/e provided that b, c, d, and e are not zero
