Ever year she gets 15 silver dollars, so she will have 64 silver dollars
Do you mean 90(3n-6) if so the answer is -270 but if you mean 3n-6 the answer is -3
Answer:
$72.90 is the interest earned
Step-by-step explanation:
The appropriate formula is i = prt, where r is the annual interest rate expressed as a decimal fraction.
Here, i = ($270)(0.09)(3 yr) = $72.90 is the interest earned
We know that
The formula to <span>find the sum of the interior angles of a regular polygon is
</span>(n - 2)*180°
where n is the number of sides
so
clear n
(n - 2)*180° = 720°-----> (n-2)=720/180---> n-2=4----> n=6 sides
the answer is
6 sides
B, D represent pairs of vertical angles.
___
Other pairs may be congruent, but they are not vertical angles. The lines that look parallel must be assumed to be NOT parallel, because they are not marked in the diagram as being parallel. Thus ∠8 ≠ ∠12, for example.
