There are 2 2-passenger taxis available so that's 2 x 2 = 4 total seats. There are 6 people needing transportation leaving 6 - 4 = 2 who will have to find other transportation.
Charlie loaned Monica $400 at an annual interest rate of 4%. If no payments are made, what is the total amount owed at the end of the first year?
| $432 | |
| $412 | |
| $428 | |
| $416 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $400
i = 0.04 x $400
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $400 + $16Simplify \( \frac{24}{80} \).
| \( \frac{3}{10} \) | |
| \( \frac{10}{19} \) | |
| \( \frac{5}{7} \) | |
| \( \frac{3}{4} \) |
To simplify this fraction, first find the greatest common factor between them. The factors of 24 are [1, 2, 3, 4, 6, 8, 12, 24] and the factors of 80 are [1, 2, 4, 5, 8, 10, 16, 20, 40, 80]. They share 4 factors [1, 2, 4, 8] making 8 their greatest common factor (GCF).
Next, divide both numerator and denominator by the GCF:
\( \frac{24}{80} \) = \( \frac{\frac{24}{8}}{\frac{80}{8}} \) = \( \frac{3}{10} \)
4! = ?
4 x 3 |
|
3 x 2 x 1 |
|
5 x 4 x 3 x 2 x 1 |
|
4 x 3 x 2 x 1 |
A factorial has the form n! and is the product of the integer (n) and all the positive integers below it. For example, 5! = 5 x 4 x 3 x 2 x 1 = 120.
