P is the principal amount, $5200.00.

r is the interest rate, 6% per year, or in decimal form, 6/100=0.06.

t is the time involved, 9....year(s) time periods.

So, t is 9....year time periods.

To find the simple interest, we multiply 5200 × 0.06 × 9 to get that: 

The interest is: $2808.00

The simple interest earned by Lisa is $2808

<u>Solution:</u>

Given that Lisa invested $5200 in a savings account with a yearly interest rate of 6% for  9 years.

<em><u>The simple interest is given as:</u></em>

\text { Simple interest }=\frac{\mathrm{p} \times \mathrm{r} \times \mathrm{t}}{100}

Where "p" is the principal amount

"r" is the rate of interest

"t" is the time period

Here p = 5200; r = 6% ; t = 9 years

\begin{array}{l}{\text { Simple interest }=\frac{5200 \times 6 \times 9}{100}} \\\\ {=\frac{280800}{100}=2808}\end{array}

So, the simple interest Lisa earn is $2808

Answer:

x=9

Step-by-step explanation:

a scale drawing means all the sides are multiplied by the same amount. to find this amount, you can divide the larger side by the bigger side by the smaller side.

15/5 = 3

12/4 = 3

therefore the scale factor is 3. to get the value of x, multiply the value of the third side by 3.

3*3=9
