<span>Randall’s family drove to the beach for vacation. Assume they drove the same speed throughout the trip. The first day, they drove 130miles in 22 hours. The second day, they drove 325 miles in 55 hours. The third day, they arrived at the beach by driving 390 miles in 66 hours.</span>
Answer:
The answer is option 3.
Step-by-step explanation:
Option 3 is correct because it has parentheses around 40 - x, but not the cube itself or the 3rd power if you didn't know what I meant. Anyway, the reason this is correct is because if you look at any order of operations, you will notice that parentheses always comes before powered numbers, so if you were to choose, say option 2, it would be a completely different answer than option 3, not to mention wrong also.
Answer:
- 76.2% total return
- 2.87% annual return
Step-by-step explanation:
The total return is the rate of increase over the whole period:
% change = (11100/6300 -1) × 100% = 76.2%
The annual return is the rate of return that gives this growth over 20 years:
(1 +r)^20 = 1 +76.2%
r = 1.762^(1/20) -1 ≈ 2.87%
The total return is about 76.2%; the annual return is about 2.87%.
