Answer:
The answer is B) the span of the roof is 4
Step-by-step explanation:
The span is 30 meters if the pitched roof is built with a 1:3 ratio of rise to span.
It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
We have:
A pitched roof is built with a 1:3 ratio of rise to span
rise/span = 1/3
rise = 10 meters
10/span = 1/3
span = 3×10 = 30 meters
Thus, the span is 30 meters if the pitched roof is built with a 1:3 ratio of rise to span.
