Answer:
The other rational number in the operation given is:
- <u>6/5</u>
Step-by-step explanation:
To obtain the number in the operation given, we're gonna represent the operation:
- r * 15/14 = 9/7
Where:
- r = the other rational number.
Now we are going to solve r to identify its value in numbers:
- r * 15/14 = 9/7
(We pass a number that is multiplying to the left of the equal, to divide to the right of the equal symbol)
As you can see, when we operate, <u>the result is 6/5</u>, and we can prove this multiplying as we had in the original equation, replacing r by 6/5:
- r * 15/14 = 9/7
- 6/5 * 15/14 = 9/7
- 9/7 = 9/7
In this form, we know the result is correct.
Answer:
a) 9000 ft-lb
b) 9000 ft-lb
Step-by-step explanation:
Equation for the work:
The equation for the work done is given by:
In which F is the force needed and d is the distance. The time does not interfere on the work.
A 300-lb gorilla climbs a tree to a height of 30 ft
This means that
Thus
The work done in both cases is of 9000 ft-lb, as the work is not a function of time.
