Answer:
$10,240
Step-by-step explanation:
y = 20,000 (.80)^t
y = 20,000 (0.80)^3
0.8^3 = 0.512
0.512 x 20,000 = 10240
Your answer would be A. $10,240.
Answer:
1,825 days
Step-by-step explanation:
730 / 2 = 365 (one year, or the number of days a single revolution around the sun takes)
Now just multiply by 5
[365 · 5 = 1,825], thus 1,825 days are the duration of 5 revolutions.
The problem could also be initially expressed as:
x = (720/2) · (5) with x representing the missing value
The answer is 683 because ik ir
Let their ages be m and t, respectively. Currently, m = 4t.
In ten years: t+10 = (1/2)(m+10).
Multiplying both sides by 2, we get 2t + 20 = m + 10. Substituting 4t for m produces
2t + 20 = 4t + 10. Then 10 = 2t, and t=5. Tamanna is currently 5 years old, and her mother is 20.
