Answer:

P = \frac{Fd}{t}

Step-by-step explanation:

Thinking process:

The concept of power is expressed as the work done per unit time.

Thus, power is given by:

Power = \frac{work}{time}

However, the work done by a force is given by:

work done = force × distance in the direction of the force

Thus, power is work per unit time given by:

P = \frac{Fd}{t}

Power= work/time, work/time=(force x displacement)/time

therefore, power= (Fd)/t

Which fraction equals the ratio of rise to run between the points (0, 0) and (6, 7)? A. B. C. D.
Svetlanka [38]

Answer:

7 / 6

Step-by-step explanation:

Given the points:

points (0, 0) and (6, 7)

Point 1 : x1 = 0 ; y1 = 0

Point 2 : x2 = 6 ; y2 = 7

The rise = y2 - y1 = 7 - 0 = 7

The run = x2 - x1 = 6 - 0 = 6

Ratio of Rise to Run = Rise / Run = 7 / 6

25 is what percent of 20?
denis-greek [22]

Answer:

20 is 80% of 25

Step-by-step explanation:

We assume, that the number 25 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 100% equals 25, so we can write it down as 100%=25.

4. We know, that x% equals 20 of the output value, so we can write it down as x%=20.

5. Now we have two simple equations:

1) 100%=25

2) x%=20

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

100%/x%=25/20

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for 20 is what percent of 25

100%/x%=25/20

(100/x)*x=(25/20)*x       - we multiply both sides of the equation by x

100=1.25*x       - we divide both sides of the equation by (1.25) to get x

100/1.25=x

80=x

x=80
