Answer:
16
Step-by-step explanation:
Using pythagorean theorem, a^2+b^2=c^2, you can substitute the legs in. 8^2+8sqrt3^2=c^2. C is the hypotenuse. you get 64+64sqrt9=c^2. This simplifies to 64+64(3)=c^2. This equals 256=c^2. Sqrt of 256 is 16, which is C.
It is 1/10 times the value represented in the 2 in 423.
It is 10 times the value represented in the 2 in 72
Answer: 1 : 20%
2 : 80%
3 : -90% (negative 90%), if no negatives are allowed, than it is a 90% decrease.
4 : $90
5: $31.50

Answer:
Neither. If they were both place on a coordinate plane, they would cross, but not perpendicular. Since they cross, they cannot be parallel either. Hope that helped
