The surface area of the prism according to the segment labels is; 480mm².
<h3>What is the surface area of the prism?</h3>
The prism given in the task content is five-faced and hence, its surface area can be evaluated as follows;
Surface area = 2(0.5×15×8)+(15×9)+(8×9) + (17×9).
Hence, the surface area of the prism upon evaluation is; 480mm².

Answer:
$27.50
Step-by-step explanation:
The amount of interest she will earn in a year is basically the initial amount multiplied by the rate of interest per year (in decimal).
We have to first convert 5 1/2% to decimal.
First,
1/2 means 0.5 (by dividing), so it becomes:
5.5%
Converting percentage to decimal is easy. We divide by 100, so we have:
5.5/100 = 0.055
Now we multiply:
500 * 0.055 = $27.5
So, in 1 year, Isabella earns an interest of $27.50
