The answer is <span>Sum of Cubes.
Since there is sign +, we expect it to be the sum. Among all choices, only the last one includes summation, and that is sum of cubes.
Let's check it out.
Sum of cubes can be expresses as:
a</span>³ + b³ = (a + b)(a² - ab + b²)
Let's see what are cube roots of 125 and 8:
∛125 = ∛5·5·5 = ∛5³ = 5 ⇒ a = 5
∛8 = ∛2·2·2 = ∛2³ = 2 ⇒ b = 2
Now, let's implement that in the equation of sum of cubes:
5³ + 2³ = (5 + 2)(5² - 5·2 + 2²)
125 + 8 = 7 · (25 - 10 + 4)
133 = 7 · 19
133 = 133
Therefore, sum of cubes is the right answer.
15 500 at 11% ordinary interest for 120 days.
=> 120 days = approximately 4 months.
=> 15 500 * .11 = 1705 dollars interest
=> 15 500 + 1750 = <span>17 205 dollars
=> </span><span>17 205 dollars - 3000 dollars after 70 days = 14 205 dollars is the amount due</span>
The first digit is 9 or 8.
The fifth odd number you count beginning with one is 9.
Let the middle number be x.
If the first number is 8, then 8 + x + 9 = 22 => 17 + x = 22 => x = 22 - 17 = 5. then the number is 859 which approximates to 900 to to the nearest hundred.
If the number is 9, then 9 + x + 9 = 22 => 18 + x = 22 => x = 22 - 18 = 4, then the number is 949, which also approximates to 900 to the nearest hundred.
Therefore, the required number is 859 or 949.
