<u><em>Answer:</em></u>
<u><em></em></u>
<u><em> 35 miles per hour</em></u>
<u><em /></u>
<u><em>Step-by-step explanation: Showing Work</em></u>
<u><em>This is a fraction equal to</em></u>
<u><em>70 miles ÷ 2 hours</em></u>
<u><em></em></u>
<u><em>We want a unit rate where</em></u>
<u><em>1 is in the denominator,</em></u>
<u><em>so we divide top and bottom by 2</em></u>
<u><em></em></u>
<u><em>70 miles ÷ 2</em></u>
<u><em>2 hours ÷ 2</em></u>
<u><em>= </em></u>
<u><em>35 miles</em></u>
<u><em>1 hour</em></u>
<u><em>= </em></u>
<u><em>35 miles</em></u>
<u><em>hour</em></u>
<u><em>= 35 miles per hour </em></u>

Answer:
<em>Option D is correct</em>
Step-by-step explanation:
Applying the cosine theorem for triangle ABC, you would have:
cos (angle BAC) = (BA^2 + CA^2 - BC^2)/(2*BA*CA)
= (10^2 + 18^2 - 20^2)/(2*10*18)
= 24/360
=> angle BAC = ~86 deg
Hope this helps!
Answer:
experimental probability = 18/30 =0.6 =3/5
frequency=3/5=0.6=60%
