Answer:
Step-by-step explanation:
Time = distance/speed
Considering the first stage,
Speed = 20km/hr
Distance = 5km
Time = 5/20 = 0.25 hour
Considering the second stage,
Speed = 10km/hr
Distance = 5km
Time = 5/10 = 0.5 hour
Considering the third stage,
Speed = 25km/hr
Distance = 5km
Time = 5/25 = 0.2 hour
Considering the third stage,
Speed = 20km/hr
Distance = 5km
Time = 5/20 = 0.25 hour
Therefore, the time it took the biker to complete the race is
0.25 + 0.5 + 0.2 + 0.25 = 1.2 hours
Area of the square bottom = L x W = 5 x 5 = 25 square cm
Area of triangle = 1/2 x base x height = 1/2 x 5 x 6 = 15 square cm
Total area = 25 + 15 = 40 square cm.
If you do PEMDAS correctly you’ll get the answer 514
Answer:
Hi
Step-by-step explanation:
To find the depreciation of the car take the amount it goes down by each year (4.1%) and make x the number of years. 34000 · (4.1% · 7) = 9758. That's your depreciation. Now just subtract the depreciation from the total and you get 24242
