Answer:
1 mile = 8.5 minutes
Step-by-step explanation:
<u>Determining the equation:</u>
Kira ran 8 1/5 miles in 69 7/10 minutes.
⇒ Kira = 8 1/5 miles = 69 7/10 minutes
⇒ 41/5 miles = 697/10 minutes
<u>Simplifying both sides:</u>
⇒ 41/5 miles = 697/10 minutes
⇒ 41 miles = 697/2 minutes
<u>Using cross multiplication:</u>
⇒ 41 × 2 miles = 697 minutes
⇒ 82 miles = 697 minutes
<u>Dividing 82 both sides:</u>
⇒ 82 miles = 697 minutes
⇒ 82/82 miles = 697/82 minutes
⇒ 1 mile = 8.5 minutes
Answer:

Step-by-step explanation:
Answer:
m < B = 22 degrees.
Step-by-step explanation:
There are 180 degrees in a triangle so we have the equation:
x + 120 + x + 16 = 180
2x = 180 - 120 - 16 = 44
2x = 44
x = 22
m < B = 22 degrees.
