Substitute the given values into the formula, and solve for the unknown variable. A=bh

Veseljchak [2.6K]

Answer:

h = 7

Step-by-step explanation:

We are given the equation A=bh , and need to work out the unknown variable .

So we substitute the values of A and b given :

70 = (10)(h)

70 = 10 × h

Divide both sides by 10 :

70 ÷ 10 = h

h = 7

Money is borrowed at 9% simple interest. After one year, $1178.29 pays off the loan. How much was originally borrowed?

$\bf ~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\dotfill&1178.29\\ P=\textit{original amount deposited}\dotfill \\ r=rate\to 9\%\to \frac{9}{100}\dotfill &0.09\\ t=years\dotfill &1 \end{cases} \\\\\\ 1178.29=P(1+0.09\cdot 1)\implies 1178.29=P(1.09)\implies \cfrac{1178.29}{1.09}=P \\\\[-0.35em] \rule{34em}{0.25pt}\\\\ ~\hfill 1081=P~\hfill$
