The interest rate equals 25%
Explanation:
Provided data:
Principal amount, P = $2,000
Total amount, A = $2500
Duration, t = 1 year
Interest rate, r =?
We understand:

Substituting the known values gives:


Thus, the interest rate is 25%
The salsa consists of 65% tomatoes, which amounts to 5.2 cups.
Let’s denote the total salsa as "x" cups, representing 100%. Given that 5.2 cups makes up 65%, we have:

The train descends at twice the speed compared to its ascent, and it travels at 2/3 of the speed uphill relative to flat terrain.
If its speed downhill is measured at 120 miles per hour, its uphill speed would be 120 divided by 2, equaling 60 miles per hour, and its speed on flat ground would be 60 divided by (2/3), simplified to (60 times 3) divided by 2, resulting in 90 miles per hour.
Consequently, for the train to cover 45 miles on flat terrain, the time required is calculated as 45 divided by 90, which is equal to 0.5 hours, or 30 minutes.
15Step-by-step explanation: If she consumes 3 cups every hour and the hike lasts for 5 hours (3 x 5 = 15), she will need a total of 15 cups of water, not just 12.
