Mathematics

Answer:

The answer to your question is letter D. x = 64

Step-by-step explanation:

Equation

                                       log x 8  = 0.5

Express the log as a exponential equation

                                        xx^{0.5} = 8

Express the power as a fraction

                                        x^{1/2} = 8

                                        \sqrt{x^{2}}

Look for a number which squared root is 8

                                        \sqrt{64} = 8

Then

                                        x = 64

Sonbull [250]
For this case we first calculate the rate in blocks per minutes.
 rate = (15.5) / (35) = 0.443 blocks per minutes.
 Then, we can go to blocks per hour.

 rate = 0.443 * (1/60) = 0.00738 blocks per hour.
