Answer: $250

Step-by-step explanation:

The computer reduces by half of its value every year. It is originally valued at $4,000 so the value in 4 years can be calculated by the formula:

= 4,000 * 0.5 ^ number of years

= 4,000 * 0.5⁴

= $250

Another method is to reduce by half every year:

First year = 4,000 / 2 = $2,000

Second year = 2,000 / 2 = $1,000

Third year = 1,000 / 2 = $500

Fourth year = 500 / 2 = $250

Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers?
blondinia [14]
Let the two integers be x and x + 1, then
2(x + 1) + 9 = 3x
2x + 2 + 9 = 3x
3x - 2x = 11
x = 11

Therefore, the integers are 11 and 12.

Wha rid the value of n very confused and need help
Slav-nsk [51]

Answer:

n = 6

Step-by-step explanation:

Two intersecting chords. The product of the parts of one chord is equal to the product of the parts of the other chord, that is

7(n + 4) = 5(n + 8) ← distribute parenthesis on both sides

7n + 28 = 5n + 40 ( subtract 5n from both sides )

2n + 28 = 40 ( subtract 28 from both sides )

2n = 12 ( divide both sides by 2 )

n = 6
