Rita is hiking along a trail that is 13.7 miles long. so far she has hiked along 1/10 of this trail. how far has rita hiked?

Answer

Find out the how far has Rita hiked .

To prove

Let us assume that the rita hiked distance be x.

As given

rita is hiking along a trail that is 13.7 miles long.

she has hiked along of this trail.

Than the equation becomes

x = 1.37 miles

Therefore  Rita hiked 1.37  miles of the a trail that is 13.7 miles long.

7.9m and 4.3°

step-by-step explanation:

let east be +x and north be +y, x = distance * cos θ, y = distance * sin θ  

for 3.5 south, y = -3.5  

for 8.2, x = 8.2 * cos 30 and y = 8.2 * sin 30  

for 15 west, x = -15  

total x = 8.2 * cos 30 – 15 ≈ -7.9  

total y = -3.5 + 8.2 * sin 30 = 0.6  

magnitude = [(8.2 * cos 30 – 15)^2 + 0.6^2)]^0.5  

the magnitude is approximately 7.9 m  

tan θ = y/x = 0.6/-7.9  

the angle is approximately 4.3˚ north of west
