Answer:
<u> 3/4 km</u>
Step-by-step explanation:
<u>turn 3/4 km into a fraction first to compare it to 0.8 km</u>

Answer:
C) 6 feet
Step-by-step explanation:
The diagram is shown in the attachment.
Using the Pythagoras Theorem,
![x^2=4^2+4^2](https://tex.z-dn.net/?f=x%5E2%3D4%5E2%2B4%5E2)
![x^2=16+16](https://tex.z-dn.net/?f=x%5E2%3D16%2B16)
![x^2=32](https://tex.z-dn.net/?f=x%5E2%3D32)
We take positive square root to obtain
![x=\sqrt{32}](https://tex.z-dn.net/?f=x%3D%5Csqrt%7B32%7D)
![x=4\sqrt{2}](https://tex.z-dn.net/?f=x%3D4%5Csqrt%7B2%7D)
x=5.66ft
Rounding to the nearest feet we have x=6ft
