Geometric series is a series of numbers where the ratios of successive terms are the same. <span> To answer this problem, the information that we need to know are the first first term, the number of terms and the ratio of any successive terms. First we get the number of terms by the equation:
an= a1(r)^(n-1) solve for n, which results to 8.
Then the sum is computed by the equation:
Sn = a1(((r)^n)-1)/(r-1))
The answer is then A 1,020</span>
Answer:
I think the answer is 16
Step-by-step explanation:
Because
2 divided by 15 is 7.5
so 120 divided 7.5 is 16 pages
I hope you get it right !
Good Luck!
(3x-2)*(4x-7)
12x^2 - 21x - 8x + 14
(12x^2 - 29x + 14) square units
Final answer: C
Answer:
The least whole number is the number 1
Step-by-step explanation:
we have
Remember that
<u>Whole numbers</u> are positive numbers, including zero, without any decimal or fractional parts [0,1,2,3,4,5,6,...]
so
Solve the inequality for x
Divide both sides by 400
Rewrite
therefore
The least whole number is the number 1
