Hello,
7) A∪C={1,2,3,4,5,7,9}
8) A∩B={2,4}
C'= complement of C ={2,4,6}
9) A∪B∩C'={1,2,3,4,6,8}∩{2,4,6}={2,4,6}
10) A∪(B∩C')={1,2,3,4}∩{2,4,6}={1,2,3,4,6}

Hello!
You can use the Pythagorean Theorem to solve this

c is the hypotenuse
a and b are the legs
Put in the values you know

Square the numbers

Subtract 2.25 from both sides

Take the square root of both sides
b = 0.8
The answer is 0.8km
Hope this helps!
