In mathematics, number sequencing of the same pattern are called progression. There are three types of progression: arithmetic, harmonic and geometric. The pattern in arithmetic is called common difference, while the pattern in geometric is called common ratio. Harmonic progression is just the reciprocal of the arithmetic sequence.
The common ratio is denoted as r. For values of r<1, the sum of the infinite series is equal to
S∞ = A₁/(1-r), where A1 is the first term of the sequence. Substituting A₁=65 and r=1/6:
S∞ = A₁/(1-r) = 65/(1-1/6)
S∞ = 78
Simply remember PEMDAS:
P = Parentheses
E = Exponents
M = Multiplication
D = Division
A = Addition
S = Subtraction
You perform these actions from left to right.
However in this case it is not possible for it to equal 60.
B I think that is the answer. If its not please let me know.
Answer:
1.0325s
Step-by-step explanation:
The expression can be simplified by combining the terms.
s + 0.0325s = s(1 +0.0325) = 1.0325s
Answer:
y=-3
Step-by-step explanation:
-2(-25)+2y=44
Substitute -25 for x
Then multiply
50+2y=44
-50 -50
Subtract 50 on both sides
2y/2=-6/2
Divide 2 and 6
Answer is -3
