Question

(Needed now please.)

An engineer wants to build a house on a beach. Buildings on the shore must be built high enough to avoid flooding from oceans during storms. The highest wave height elevation measured for storms in the area is 15 feet. The support beams must reach a depth of 7 feet underground. Based on scientific knowledge, which of these support beams would be the best to use for the building?

1. Support beams 15-20 feet in length
2. Support beams 25 feet or greater
3. Support beams greater than 7 feet
4. Support beams greater than 15 feet

Answer 1

The answer is "Support beams 25 feet or greater"

Step-by-step explanation:

Just took the FLVS test and its right!

Answer 2

Support beams 25 feet or greater

Step-by-step explanation:

The highest wave height is 15 feet, the beams must reach a depth of 7 feet underground. 15+7 = 22feet, to avoid the highest wave it must be at least 22 feet and in this case:

1, Support beams 15-20 feet in length (not satisfy because it <22)

2, Support beams 25 feet or greater (satisfy because it >22)

3, Support beams greater than 7 feet (not satisfy because >7 is not enough, it must >22)

4, Support beams greater than 15 feet (not satisfy because >15 is not enough, it must >22)

Hope this help you :3
