Y=1/5x-3 (subtract x on each side then divide each by 6)
The speed upstream is the difference between the boat speed and the current speed. It is (12 mi)/(4 h) = 3 mph.
The speed downstream is the sum of the boat speed and the current speed. It is (32 mph)/(4 h) = 8 mph.
The speed of the boat is the average of these: (3 + 8)/2 = 5.5 mph.
The speed of the current is that less the difference: 5.5 - 3 = 2.5 mph.
_____
<u>Check</u>
Boat + Current = 5.5 + 2.5 = 8 mph
Boat - Current = 5.5 - 2.5 = 3 mph
12/25 as a percentage is 48%
So, since our denominator in 12/25 is 25, we could adjust the fraction to make the denominator 100. To do that, we divide 100 by the denominator: Now we can see that our fraction is 48/100, which means that 12/25 as a percentage is 48%. Once we have the answer to that division, we can multiply the answer by 100 to make it a percentage: And there you have it! Two different ways to convert 12/25 to a percentage. Both are pretty straightforward and easy to do, but I personally prefer the convert to decimal method as it takes less steps.
Answer:
Step-by-step explanation:
It is assumed the interest is simple.
<u>Use the interest formula:</u>
<u>We have:</u>
- I = 13200
- P = 24000
- r = 11% = 0.11
<u>Substitute values and solve for t:</u>
- 13200 = 24000*0.11t
- 13200 = 2640t
- t = 13200/2640
- t = 5 years
