Answer:
I. Amount = 5618 Rupees
II. Compound interest = 618 Rupees
Step-by-step explanation:
- Given the following data;
- Principal = 5000 Rupees
- Time = 2 years
- Interest rate = 6%
To find the compound interest;
Mathematically, compound interest is calculated using the formula;
A = P(1 + r)^t
Where;
- A is the future value.
- P is the principal or starting amount.
- r is annual interest rate.
- t is the number of years for the compound interest.
Substituting into the formula, we have;
A = 5000(1 + 0.06)^2
A = 5000(1.06)^2
A = 5000 * 1.1236
<em>A = 5618 Rupees</em>
Next, we would determine the compound interest using the formula;
C.I = A - P
C.I = 5618 - 5000
<em>Compound interest (C.I) = 618 Rupees</em>
Answer:
- 1.25 hours or 1 hour and 15 minutes
Step-by-step explanation:
<em>Question</em>
- <em>Lisa lit a candle with a height of 8 inches. When lit, this candle loses 10% of its original height every hour. </em>
- <em>Please complete the following sentence by writing the number in the blank.
Until the candle has been burning for at least _______ hours, the height of Jennifer's candle will be more than 7 inches.</em>
<u>Candle looses 10% of 8 inches, it equals:</u>
- 8*0.1 = 0.8 inches an hour
<u>Let x be required time, then:</u>
- 8 - 0.8x > 7
- 0.8x < 8 - 7
- 0.8x < 1
- x < 1/0.8
- x < 1.25
- or 1 hour 15 minutes
He would need 10.6 shelves. (Also what kind of shelf can only hold 9 books?)
