Answer:
<h2>A = 20</h2><h2>P = 6√10</h2>
Step-by-step explanation:
The formula of a distance between two points:
A(-3, 0) , B(3, 2)
A(-3, 0), D(-2, -3)
AB = CD and AD = BC

Answer:
- kayak: 12 mph
- current: 2 mph
Step-by-step explanation:
Bunny's rate downstream is ...
(70 mi)/(5 h) = 14 mi/h = k + c
Bunny's rate upstream is ...
(70 mi)/(7 h) = 10 mi/h = k -c
The kayak speed is the average of these:
(14 mi/h +10 mi/h)/2 = ((k +c) +(k -c))/2
(24 mi/h)/2 = 2k/2
12 mi/h = k
Then the current speed is ...
c = k -10 = 12 -10 = 2 . . . . mi/h
The still-water speed of the kayak is 12 mi/h; the speed of the current is 2 mi/h.
_____
<em>Additional comment</em>
World-class kayak paddlers will not maintain a speed more than 8 mi/h for that distance and/or time (140 miles in 12 hours). Bunny is exceptional.
Answer:
15
Step-by-step explanation:
2 times 4 is 8 minus 2 equals 6- Nia's Score
2 times 6 is 12 plus 3 equals 15- Mark's Score

Answer: <em>
17</em></h3>
Step-by-step explanation:
<em>Pythagorean Theorem</em>
<em>a^2+b^2=c^2</em>
<em>8^2+15^2=c^2</em>
<em>64+225=c^2</em>
<em>289=c^2</em>
<em>Now square both sides</em>
<em>x=17</em>
Answer:
97.7°
Step-by-step explanation:
Supplementary angles are angles that add up to 180° together so 180-82.3=97.7
