A walker has travelled 9 km along a trail. If he has completed 80% of the trail, how much further does he still have to go?
Anit [1.1K]

Answer:

2.25 km to go

Step-by-step explanation:

In order to get this answer, you have to figure out how many km 10% is, 0.1125. Then multiply that by the remaining 20% because he already finished 80% of the trail. So, 0.1125 x 20 = 2.25.

Hope this helps! :)

neonofarm [45]

Answer: x=4.7434

Step-by-step explanation:

Use the pythagorean theorem a^{2} +b^{2} =c^{2}

plug in and solve

x^{2} +3x^{2} =(3\sqrt{10}) ^{2}

4x^{2} =90

x^{2} =22.5

x=4.7424

if you need to solve for the sides

3x = 3(4.7434) = 14.2302
