The rise and span for a roof are shown. the pitch of a roof is the ratio of the rise to the half-span. if the rise is 8 feet and the span is 30 ft, what is the pitch in simplest form?

i believe the correct answer is b.

the answer is:

the correct option:

b.

to solve the problem, we need to remember how to operate to simplify exponential expressions using the logarithms.

we are given the equation:

then, using placing logarith with base 7 on both sides of the equation, we have:

so, rounding the obtained result to two decimal places (nearest hundreth), we have:

hence, we have that the correct option:

b.

have a nice day!
