Without doing any calculation compare expression 8 to a special B A 5/6 * 250 B (1/3 x 250) + (1/2 * 250)

1 answer

To compare the expressions \( 8 \) and \( B \left( \frac{5}{6} \times 250 \right) + B \left( \frac{1}{3} \times 250 \right) + B \left( \frac{1}{2} \times 250 \right) \), we can analyze the component parts without doing any actual calculations.

  1. First Term: \( B \left( \frac{5}{6} \times 250 \right) \)

    • This term is dependent on the value of \( B \). Its value will be a little less than \( 250 \) because \( \frac{5}{6} \) represents a little less than \( 1 \).
  2. Second Term: \( B \left( \frac{1}{3} \times 250 \right) \)

    • This term will be approximately \( \frac{250}{3} \), which is around \( 83.33B \).
  3. Third Term: \( B \left( \frac{1}{2} \times 250 \right) \)

    • This term simplifies to \( 125B \).

Combining these terms, we have:

\[ B \left( \frac{5}{6} \times 250 \right) + B \left( \frac{1}{3} \times 250 \right) + B \left( \frac{1}{2} \times 250 \right) \]

Adding these gives:

\[ B \left( \frac{5 \times 250}{6} + \frac{250}{3} + \frac{250}{2} \right) \]

Now, we can look at the right-hand side without calculating the exact values. The sum of these fractions will yield a total that scales with \( B \).

Notably, for comparison:

  • \( B(125 + \frac{250}{2} + \frac{250}{3}) \) will vary greatly depending on \( B \).
  • Since \( 125 + \frac{250}{2} + \frac{250}{3} \) simplifies to something clearly larger than the \( 8 \) (since the individual components imply values of \( B \) which are at least nonzero and likely greater than \( 8 \), provided \( B \) is positive).

Thus, without calculating exact numerical values, we can infer:

  • If \( B \) takes a non-negative value, the expression on the right will almost certainly exceed \( 8 \).
  • Therefore, \( 8 \) would be less than or equal to the combined expression if \( B \) is positive.

Conclusion:

Assuming \( B \) is a positive constant, the expression \( B \left( \frac{5}{6} \times 250 \right) + B \left( \frac{1}{3} \times 250 \right) + B \left( \frac{1}{2} \times 250 \right) \) is likely greater than \( 8 \).
