A man borrowed $3700 from a bank for 6 months. A friend was co-signer of the mans personal note. The bank collected 8.5% simple

Tpy6a [65]

Answer:

(A) $157.25

(B) $3,857.25

Step-by-step explanation:

The given values are:

Principle (P)

= $3700

Time (T)

= 6 months i.e., 1/2 years

Rate (R)

= 8.5%

(A)

As we know,

Simple Interest,

⇒ $SI=\frac{P\times R\times T}{100}$

On putting the values, we get

⇒ $=\frac{3700\times 8.5\times \frac{1}{2} }{100}$

⇒ $=\frac{15,725}{100}$

⇒ $=157.25$ ($) (he paid for the use of money)

(B)

Amount he paid to the bank will be:

⇒ $P+SI$

⇒ $3700+157.25$

⇒ $3,857.25$ ($)

The quantity y varies directly with the square of x and inversely with z. When x is 9 and z is 27, y is 6. What is the constant

ira [324]

$\bf \qquad \qquad \textit{double proportional variation}
\\\\
\begin{array}{llll}
\textit{\underline{y} varies directly with \underline{x}}\\
\textit{and inversely with \underline{z}}
\end{array}\implies y=\cfrac{kx}{z}\impliedby 
\begin{array}{llll}
k=constant\ of\\
\qquad variation
\end{array}\\\\
-------------------------------$

$\bf \stackrel{\textit{\underline{y} varies directly with the square of \underline{x} and inversely with \underline{z}}}{y=\cfrac{kx^2}{z}}
\\\\\\
\textit{we also know that }
\begin{cases}
x=9\\
z=27\\
y=6
\end{cases}\implies 6=\cfrac{k9^2}{27}
\\\\\\
\cfrac{27\cdot 6}{9^2}=k\implies 2=k$
