2) AC: 7/2 = 3.5,AB: 6/2 =3, and BC: 4/2 = 2

3) AC: (7)3 2/3 = 25.7 or 25 2/3, AB: 6(3 2/3) = 22, BC: 4(3 2/3) = 14.7 or 14 2/3

The volume

Sedaia [141]

$\bf \begin{array}{cccccclllll}
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{{ k}}&\cdot&x
&& y={{ k }}x
\end{array}\\ \quad \\
$

and also

$\bf \begin{array}{llllll}
\textit{something}&&\textit{varies inversely to}&\textit{something else}\\ \quad \\
\textit{something}&=&\cfrac{{{\textit{some value}}}}{}&\cfrac{}{\textit{something else}}\\ \quad \\
y&=&\cfrac{{{\textit{k}}}}{}&\cfrac{}{x}
&&y=\cfrac{{{ k}}}{x}
\end{array}
$

now, we know that V varies directly to T and inversely to P simultaneously
thus $\bf V=T\cdot \cfrac{k}{P}$

so $\bf V=T\cdot \cfrac{k}{P}\qquad 
\begin{cases}
V=42\\
T=84\\
P=8
\end{cases}\implies 42=\cfrac{84k}{8}\implies 4=k
\\\\\\
V=\cfrac{4T}{P}\qquad now\quad 
\begin{cases}
V=74\\
P=10
\end{cases}\implies 74=\cfrac{4T}{10}\implies 185=T$

$1,250 was deposited into an account for 2 years with a 2.5% interest rate. What is the in

raketka [301]

I will assume it is 2.5% interest rate over 2 years and not per year. If this isn’t the case then let me know.
-
-
Well $1250 divided by 100 = $12.50
This is 1%-
-
-
To make 2.5% we do-> $12.50 x 2.5= $31.25
This makes our interest rate $31.25
-
-
-
-
To get our total amount.....
$1250 + $31.25 = $1281.25
