Answer:
r = -6
Step-by-step explanation:
6r + 7 = 13 + 7r
-6r both sides
7 = 13 + r
-7 both sides
r + 6 = 0
-6 both sides
r = -6
1,503 + 847 + 4,219 = 6,569
A = P(1 + rt)
1565 = 625(1 + (0.047)(t))
2.504 = 1 + 0.047t
1.504 = 0.047t
t = 32
I hope this is correct! (Sorry I haven't done simple interest in a while.)
Answer:
7740° / 45
Step-by-step explanation:
The sum of the interior angles is given by this formula: (n - 2) * 180°. So a regular 45-gon would have interior angles that add up to: (45 - 2) * 180°. = 43 * 180°. = 7740°. Now divide that by the 45 angles to find the measure of one interior angle
