Answer
Given series,
12 + 18 + 24 + 30 + . . . + 198
first term of series, a = 12
common difference,d = 18- 12 = 6
Last term of the series, a_n or l = 198.
a) The expression of arithmetic sequence given by the explicit rule is
b) number of terms in the series
c) value of the series
Answer: 4 ft
Step-by-step explanation:
Area = Length * Width
10 = 2.5x
10/2.5 = 2.5x/2.5
4 = x
Answer:
6.25%
Step-by-step explanation:
% change= (chnage/original salary) × 100%
Change = new salary - original salary
Hence = 3400-3200=200
% change= (200/3200)×100%= 6.25%
The lowest common multiple of 3, 5, and 7 is 105, so
that's the smallest number that has those prime factors.
Every multiple of 105 is another one:
210, 315, 420, etc.
So is (105) times (any multiple of 3 or 5 or 7):
(x 3, 6, 9) 315, 630, 945, etc.
(x 5, 10, 15) 525, 1050, 1575, etc.
(x 7, 14, 21) 735, 1470, 2205, etc.
Because of this statement, x + y = a as well.
