Answer:
Geometric sequence
common ratio
1/8 (or 0.125)
Step-by-step explanation:
To get to the next number we have the mulitply the one before by 1/8
Because we are multiplying each time it's a geometric sequence
Because it's a geometric sequence we have a common ratio
I wrote before that to get to the next number we have to multiply it by 1/8 so that's the common ratio
The first y is actually -30 bc a negative times a positive is always a negative
-30
45
0
-10
-40

Answer:
- 8
Step-by-step explanation:
Formula:
(3.14)r^2
Larger one:
(3.14)(3)^2
28.26 * 13
367.38 in^2
Smaller one:
(3.14)(3)^2
28.26 * 8
226.08 in^2
Step-by-step explanation:
1st
8x-59 + 2x-11 = 180
10x -70 = 180
10x = 180 + 70
10x = 250
x = 25
2nd
8x - 59 = 15y + 6
8(25) -59 = 15y + 6
200 -59 = 15y + 6
141 = 15y + 6
15y + 6 = 141
15y = 141 - 6
15y = 135
y = 135/15
y = 9
