Answer:
t = 5 seconds h = 128 feet
Step-by-step explanation:
The given equation of the object is :
.....1
When it hits the ground,
h(t) = 0
So,
The object will hit the ground in 5 seconds.
Now, put t = 1 s in equation (1).
The object is at a height of 128 ft at 1 second.
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
5 1/2 pages in 12 minutes.
11/2 pages in 12 minutes
How many pages in an hour?
well, an hour has 60 minutes
Let's write a proportion
11/2 / 12 = x/60
cross multiply
(11/2 * 60) = 12x
330 = 12x
divide both sides by 12
27.5 or 27 1/2 = x
27.5 pages per hour.
Hope this helps
Answer:
A = 173 m²
Step-by-step explanation:
P = 60m = 3L => L = 60 : 3 = 20 m
A = L×h/2 = 20m×17.3m/2 = 10m×17.3m = 173 m²
