Answer:
- 8, 20, 32, 44, 56
- arithmetic
Step-by-step explanation:
The words "common difference" tell you this is an arithmetic sequence. A geometric sequence will have a <em>common ratio</em> between terms.
__
The common difference is added to each term to get the next.
first term: 8 -- given
second term: first term + common difference = 8 + 12 = 20
third term: 20 +12 = 32
fourth term: 32 +12 = 44
fifth term: 44 +12 = 56
The first 5 terms of this arithmetic sequence are 8, 20, 32, 44, 56.
Answer:
Angle 1 = 41°
Step-by-step explanation:
Since they are both vertical angles
(6x+11)° = (10x-9)°
6x - 10x = -9 - 11
-4x = -20
4x = 20
x= 5.
Therefore,
Angle 1 = 6(5) + 11
Angle 1 = 30 + 11
Angle 1 = 41°
Answer:
A= $11500
Step-by-step explanation:
Step one:
given data
P=10,000.00
r=5%,and
t=3 years
Required
The final amount A
Step two:
assuming a simple interest we have
A= P(1+rt)
substitute
A= 10000(1+0.05*3)
A= 10000(1+0.15)
A=10000(1.15)
A=$11500
Answer:
Dividing in unit form
9 ten thousand = 9 × 10000 = 90000
90000 ÷ 10 = 9000
Dividing the sum in Standard Form
90000 = 9 × 10⁵
10 = 10¹
[9 × 10⁵] ÷ 10¹ = 9 × 10
