1) Let's first find how many calories a runner burns on 1 km: R=120/1.6= 75 (calories/km)
2) On 5 km he will burn: Calories=5*R=5*75= 375 (calories)
______
375 calories he would burn on 5 km.
Answer:
B. 52 beats/min
Step-by-step explanation:
while resting her heart beats : 36×2 = 72 beats/min
while running her heart beats : 1 860÷15 = 124 beats/min
difference = 124-72 = 52 beats/min

It would be d because she is choosing a line of reflection so she would us a parallel line to line it up to the side of the polygon
Hey there!
All the angles in a triangle add up to 180.
So,
70+30+x=180
100+x=180
x=80
I hope this helps!
