Answer:
a) 5/18 hour
a) 3 3/5 tasks
Step-by-step explanation:
A robot can complete 3tasks in five sixth hour. Each task takes the same amount of time.
a. How long does it take the robot to complete one task?
3 tasks => 5/6 hour
1 task => x
3x = 1 × 5/6 hour
x = 5/6 ÷ 3
x = 5/6 × 1/3
x => 5/18 hour
b. How many tasks can the robot complete in one hour?
5/6 hour = 3 tasks
1 hour =>x tasks
5/6x = 1 × 3
x = 3 ÷ 5/6
x = 3 × 6/5
x = 18/5
x = 3 3/5 tasks

Kim ran a mile in PE class. After resting for 1 hour her heart rate was 75 beats per minute. If her heart rate decreased by ⅖ , what was it immediately after she ran the mile?
Answer:
125
Step-by-step explanation:
since you take away 2/5 of the original number to get 75, 75 is equal to 3/5's of the original. You then divide 75 by 3, get 25, then multiply 25 by 5 to find the answer which is 125.
what happens to the potential energy of the atoms during a phase change ?
Answer:
The energy that is changing during a phase change is potential energy. During a phase change, the heat added (PE increases) or released (PE decreases) will allow the molecules to move apart or come together. Heat absorbed causes the molecules to move farther apart by overcoming the intermolecular forces of attraction.
Answer: I believe it turns into kinetic energy
Step-by-step explanation:
Kinect energy is the opposite of potential energy

Solve: | x-3 | + 2 = −3
|x−3|+2=−3|x-3|+2=-3
Move all terms not containing |x−3||x-3| to the right side of the equation.
|x−3|=−5
Remove the absolute value term. This creates a ±± on the right side of the equation because |x|=±x|x|=±x.
x−3=±(−5)
Set up the positive portion of the ± solution.
x−3=−5
Move all terms not containing x to the right side of the equation.
x= −2
Set up the negative portion of the ± solution.
x−3 =5
Move all terms not containing x to the right side of the equation.
x=8
The solution to the equation includes both the positive and negative portions of the solution.
x=−2, 8
