Find the length of LM. Show your work.

kicyunya [14]

Answer:

Solution,

<N=180-53-44

 =83

<h3>Apply sines rule,</h3>

 $\frac{lm}{sin \: 83} = \frac{14}{sin44} \\ lm = \frac{14 \: sin \: 83}{sin \: 44} \\ lm = 20$ 

hope this helps..

Good luck on your assignment..

A motorcyclist leaves City A and rides at a constant speed towards City B, which is 225 km away. After 1.5 hours, the motorcycli

rewona [7]

Answer:

50 km/hr

Step-by-step explanation:

OK, this is how I solved this problem.

Let r = original rate of speed

t = time after the stop to finish the trip

Time for trip without stopping is 225/r

(1) 1.5 + .5 + t = 225/r This is a time equation

(2) 1.5r + t(r + 10) = 225 This is a distance equation

(1) 2 + t = 225/r (2) 1.5r + tr + 10t = 225

2r + tr = 225

tr = 225 - 2r 1.5r + 225 - 2r + 10(225/r - 2) = 225

t = 225/r - 2

-.5r + 225 + 2250/r - 20 = 225

-5r + 2250 + 22500/r - 200 = 2250

-5r^2 + 2250r + 22500 - 200r = 2250r

5r^2 + 200r - 22500 = 0

5(r^ + 40r - 4500) = 0

5(r - 50)(r + 90) = 0

r = 50 or r = -90

The rate cannot be negative, so the original speed 50 km/hr

This not an easy problem and I hope you were able to follow my work

5x + 2x + 2 = 9x + 4

bija089 [108]

Step-by-step explanation:

Given

5x + 2x + 2 = 9x + 4

9x - 5x - 2x = 2 - 4

9x - 7x = - 2

2x = - 2

x = - 2 / 2

Therefore x = -1.

During a recent snowstorm, Boston got 2.8

ipn [44]

New York got 4.64 times more snow than Boston did.

If Boston got 2.8 feet of snow and New York City got 13 feet, the amount of feet that New York got more than Boston is:

= Amount of snow New York got / Amount of snow Boston got

= 13 / 2.8

= 4.64 more than Boston

New York therefore got about 4.64 more snow than Boston did
