Lisa is 50 years

Sam is 50 / 2 = 25 years

Brad is 25 * 3 = 75 years

Let the ages of these three persons  be represented by L, S and B.  Then,

L=2S, and B/3=S.

With L=50, 50=2S, and so S= 25.

Since B/3=S, B=3S, so that B here is 75.

Lisa is 50, Brad is 75 and Sam is 25 (years of age).

7% of what lenght is 200 ft?
Nastasia [14]
If you would like to solve 7% of what length is 200 ft, you can calculate this using the following steps:

7% of what length is 200 ft
7% * x = 200
7/100 * x = 200      /*100/7
x = 200 * 100 / 7
x = 2857 ft

Result: 7% of 2857 ft is 200 ft.

Each sequence has eight terms. Evaluate each related series. 1,-1,-3, . . . . . . -13
o-na [289]

The sum of the 8 terms of the series 1-1-3-5- ... -13 is -48

The given sequence is:

1,-1,-3,  . . -13

and there are 8 terms.

The related series of this sequence is:

1-1-3-5- ... -13

Notice that the series is an arithmetic series with:

first term, a(1) = 1

common difference, d = -1 - (1) = -2

last term, a(8) = -13

To find the sum of the series, use the sum formula:

S(n) = n/2 [(a(1) + a(n)]

Substitute n = 8, a(1) = 1, a(n) = a(8) = -13 into the formula:

S(8) = 8/2 [1 + (-13)]

S(9) = 4 . (-12) = -48
