Answer:
a = 8 m
Step-by-step explanation:
Since, given is an isosceles right triangle.
So, by Pythagoras theorem:
![{a}^{2} + {a}^{2} = {(8 \sqrt{2} )}^{2} \\ \\ 2 {a}^{2} = 128 \\ \\ {a}^{2} = \frac{128}{2} \\ \\ {a}^{2} = 64 \\ \\ a = \sqrt{64} \\ \\ a = 8 \: m](https://tex.z-dn.net/?f=%20%7Ba%7D%5E%7B2%7D%20%20%2B%20%20%7Ba%7D%5E%7B2%7D%20%20%3D%20%20%7B%288%20%5Csqrt%7B2%7D%20%29%7D%5E%7B2%7D%20%20%5C%5C%20%20%5C%5C%202%20%7Ba%7D%5E%7B2%7D%20%20%3D%20128%20%5C%5C%20%20%5C%5C%20%20%7Ba%7D%5E%7B2%7D%20%20%3D%20%20%5Cfrac%7B128%7D%7B2%7D%20%20%5C%5C%20%20%5C%5C%20%20%7Ba%7D%5E%7B2%7D%20%20%3D%2064%20%5C%5C%20%20%5C%5C%20a%20%3D%20%20%5Csqrt%7B64%7D%20%20%5C%5C%20%20%5C%5C%20a%20%3D%208%20%5C%3A%20m)
Answer:
1st one= B 25 cents
2nd one= D 2 miles
Step-by-step explanation:
1.
8x3=24
6/24=25
= 25 cents
2.
1.6 km= 1 mile
so 1/2 of a mile =
0.8 km
1/4 of an hour = 15 minutes
0.8km= 15 minutes
15x3= 45 minutes
0.8km x 3= 2.4km
2.4km = 2 miles
