Hello!
The recursive rule for an arithmetic sequence:
.
The explicit rule for an arithmetic sequence:
.
is the value you are trying to find, or simply the answer. :)
is the common difference of the sequence.
is the first term of the sequence.
Given,
and
...
The common difference is -6, and the first term is 8.
Plug these values into the explicit rule for an arithmetic sequence, you get:
.
Therefore, the answer is A,
.
If you wondered why,
is equal to
, the Commutative Property of Multiplication states that when two numbers are multiplied together, the answer is the same regardless of the order of the numbers, which makes
and
equal to each other.
Answer:
75.2 kg
Step-by-step explanation:
His mass now is 80 kg which is 100% of his mass since 100% is the entire amount. He wishes to reduce his mass by 6%.
100% - 6% = 94%
After reducing his mass by 6%, his mass will become 94% of his original mass, 80 kg.
We need to find 94% of 80 kg.
94% of 80 kg = 94% × 80 kg = 0.94 × 80 kg = 75.2 kg
They are both a divisible by 7
1. 30 MPH
(divide hours (4.5) from miles (120))
2. $55.80
(divide fencing per cost (8) from cost (12.40) to get how much it costs per foot (1.55) then multiply it by how much feet you need (36))
