Hi sorry for the late response, I know the assignment was due at 5pm today but anyway here is the answer.

System:

<em>d= 5(0.75-t)</em>

<em>d= 20t</em>

<em>20t = 3.75 -5t</em>

Define Variables:

<em>d = how far Carol Skied</em>

<em>t = time it took Carol to go up/down</em>

Solve:

20t = 3.75 -5t

20t + 5t = 3.75 -5t + 5t            

25t = 3.75

25t/25 = 3.75/25

t = 0.15

<u><em>Now we plug in the time into the Distances:</em></u>

20t = 3.75 - 5t

20(0.15) = 3.75 - 5(0.15)

3 = 3.75 - 0.75

3 = 3

Solution as Sentence:

<u><em>Carol Skied 3 miles</em></u>

<u><em /></u>

Answer:

m MN = 70°

Step-by-step explanation:

∠MLN is an angle formed by the chords ML and LN and is calculated as

∠MLN = 0.5( m arc MN ), that is

35° = 0.5 arc MN ( multiply both sides by 2 )

arc MN = 2 × 35° = 70°
