Answer: the difference between the max is 3200.
Step-by-step explanation:
20000-16800= 3200
Here we have a negative times a positive number. In this case The answer is always negative.
-1.15 * 3.2 = - 3.68
Answer:
11.11% (nearest hundredth)
Step-by-step explanation:
<u>Simple interest formula</u>
A = P(1 + rt)
where:
- A = final amount
- P = principal
- r = interest rate (in decimal form)
- t = time (in years)
Given:
- A = $3500
- P = $2800
- t = 2 years 3 months = 2.25 years
Substitute given values into the formula and solve for r:
⇒ 3500 = 2800(1 + 2.25r)
⇒ 3500 = 2800 + 6300r
⇒ 700 = 6300r
⇒ r = 1/9
Convert the interest rate into a percentage:
⇒ r × 100% = 1/9 × 100% = 11.11% (nearest hundredth)

Answer:
24 days
Step-by-step explanation:
The distance from A to B equals the distance from B to A.
Let the distance between A and B be d.
3 days = 72 hours
4 days = 96 hours
speed = distance/time
speeds are in miles per hour
speed from A to B = d/72
speed from B to A = d/96
difference in speeds:
d/72 - d/96 = d/288
The speed of the water is half of the difference.
speed = d/576
When the raft floats from A to B, it uses only the speed of the water.
d/576 / d/72 = 1/8
The speed of the water is 1/8 the overall speed of the trip from A to B, so traveling by the speed of the water alone must take 8 times longer than with the boat motor.
8 * 3 days = 24 days
