PLEASE HELP !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer:

$R = \frac {3ST}{2S + T}$

Step-by-step explanation:

Given the equation;

$\frac {3}{R} - \frac {1}{S} = \frac {2}{T}$

Rearranging the equation, we have;

$\frac {3}{R} = \frac {2}{T} + \frac {1}{S}$

Lowest common multiple (LCM) of S and T is ST.

$\frac {3}{R} = \frac {2S + T}{ST}$

Cross-multiplying, we have;

$3ST = R(2S + T)$

Making R, the subject of formula;

$R = \frac {3ST}{2S + T}$

if the minute hand of the <u>circular clock</u> is 28 inches, that simply means its radius is 28.

$\bf \textit{area of a circle}\\\\A=\pi r^2~~\begin{cases}r=radius\\[-0.5em]\hrulefill\\r=28\end{cases}\implies A=\pi 28^2\implies A=784\pi$

so it covers that much in 1 rotation, so in 4 rotations that'd be 4(784π) => 3136π.

Dave buys a basketball for $20 plus an 8% tax. Mel bought a football for $28 plus an 8% tax. Enter the difference that Dave and

Neko [114]

Answer:

Dave:

$20 + 8% of 20 = $21.6

Dave payed a total of $21.6 for the basketball.

Mel

$28 + 8% of 28 = $30.2

Mel payed a total of $30.2 for the football.

$30.2 - $21.6 = $8.6

The difference is $8.6.
