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
Both angles OML and OPL are right angles (90 degrees) because they are located at the point of intersection of a tangent line to a circle.
Answer:
Yes!
Step-by-step explanation:
Case 1:
(m + n) * 7 = 7m + 7n
Case 2:
Multiplying m by 7 = 7m
Multiplying n by 7 = 7n
Adding them, we get, 7m + 7n, which is the same result in case 1.
Therefore, they do produce the same result
