If 100% of the answers are correct ; 1*110 = 110 answers are correct.
if 50% of the answers are correct ; 0.5*110 = 55 answers are correct.
if 38% of the answers are correct ; 0.38*110 = 41.8 answers are correct.
Because the number of answers needs to be a whole number; the number of correct answers is 41.

Answer:
3.3 m
Step-by-step explanation:
The formula used to solve for leg a of a right triangle is a= sqrt(c^2-b^2). This is replaced by sqrt(6^2-5^2) for your equation. If you work this out, it equals about 3.32, and you have to round it to the nearest tenth, so the answer is 3.3 m.
