C; 50 is the answer, since two of the sides are congruent...100/2 is 50
Answer:
36
Step-by-step explanation:
In order to find the speed at which the boat is traveling, we divide the distance it has traveled by the time elapsed:
2.5/20=0.125 miles/minute
Next, we want to find how long it took for the boat to travel 10 miles. Since it travels 0.125 miles every minute, we just divide:
10/0.125=80
Thus, it took 80 minutes for the boat to reach the bridge
100/5= 20
20 x 4 = 80
80 + 43 = 123
if my math is correct then none are correct
(prolly a typo)
The slope is 5/-8
Since rise/run...
Rise = +5 and Run = -8
