Answer:
4
Step-by-step explanation:
The sum of n terms of a geometric series with first term a1 and common ratio r is given by ...
Sn = a1·(r^n -1)/(r -1)
for r=5 and n=6, this becomes ...
15624 = a1·(5^6 -1)/(5 -1) = a1·(15624/4)
Then we have ...
1 = a1/4 . . . . . divide by 15624
4 = a1 . . . . . . multiply by 4
The first term of the series is 4.
9.327 rounds to 9.3
5.72 rounds to 5.7
4132 rounds to 4132
9.3 + 5.7 + 4132 =
15 + 4132 = 4147
Answer:
120°
i finished the quiz and that what i got
and for the rest
1.b
2.d
3.a
4.c
and number 5 is the first answer that i wrote
Step-by-step explanation:
When anything is bisected, the two halves are equal. This means
(-159 - 12x) = (3x + 96)
-255 = 15x . . . . . . . . . . . . . add 12x-96
-17 = x
Then either of the smaller angles is
(3(-17) + 96)° = 45°
angle ABC is twice this value, or 90°.
Let p = number of pennies we need to find.
(3/10)/(4/5) = p/440
Solve for p to find your answer.
