8. Lesly took a test with 30 questions. The ratio of correct answers to incorrect answers

Firlakuza [10]

Lesly got 14 answers correctly.

Let the correct answers be C.

Let the incorrect answers be I.

Given the following data:

Total number of questions = 30 questions.

Ratio of C to I = 7 : 8

C to I = 7 + 8 = 15

To find the number of answers she got correctly;

$C = \frac{7}{15}$ × $30$

$C = 7$ × $2$

Correct answers, C = 14 answers

Therefore, Lesly got 14 answers correctly.

Answer:

Is only if a Biconditional?

The general form (for goats, geometry or lunch) is: Hypothesis if and only if conclusion. Because the statement is biconditional (conditional in both directions), we can also write it this way, which is the converse statement: Conclusion if and only if hypothesis.

Solve for x logx+log(x-4)=2log5

sleet_krkn [62]

$\log{x} + \log{(x-4)} = 2 \log{5}\\\\
\log{\big(x(x-4)\big)} = \log{5^2}\\\\
\log{(x^2-4x)} = \log{25} \\\\
x^2-4x = 25\\\\
x^2-4x-25=0 \\\\
x = \frac{4 \pm\sqrt{16+100}}{2} \\\\
x = \frac{4\pm2\sqrt{29}}{2} \\\\
x = 2 \pm \sqrt{29} \\\\
\text{But } x > 0 \implies x = 2 + \sqrt{29}$
