Answer:
<h2><em>
30page essay/min</em></h2>
Step-by-step explanation:
Speed is the change in distance of a body with respect to time.
Speed = Distance/Time
If the library made a copy of leslie's 3 page essay in just 1/10 of a minute, this means that she made 3 pages in (1/10 * 60)secs i.e 6secs
To get the speed, we need to calculate the amount of page of essay that are produced in a minute (60secs).
If 3 page essay = 6secs
x page essay = 60 secs
cross multiply
3*60 = 6x
180 = 6x
x = 180/6
x = 30
<em>This shows that 30 page essays are produced in just a minute. Hence the speed of the copy machine is 30page essay/min.</em>
Coefficient is the correct answer
Answer:
Step-by-step explanation:
1 3/5 + 2 5/10 = 26/10 +25/10 = 51/10
The answer is 12 J.
The kinetic energy (KE) of an object is expressed as the product of half of the mass (m) of the object and the square of its velocity (v²):

The unit of the kinetic energy is Joules (J = kg · (m/s)²).
It is given:
m = 1.5 kg
v = 4 m/s
It is unknown:
KE = ?
Thus:

Therefore, the kinetic energy of the bird is 12J.
Answer:
s = 3.75 miles/hour
Step-by-step explanation:
Distance covered = 1/4 of a mile
Time taken = 1/15 of an hour
We need to find the speed of the track. We know that,

So, the required speed is 3.75 miles/hour.
