A number line going from 0 to 4. Numbers 0, 1, 2, 3, and 4 are marked on the line. Marks divide the spaces between each number into 2 equal parts. Ms. Cole has 4 yards of string. She cuts the string into pieces that are each 1 2 yard long. How many pieces of string does Ms. Cole have?
Answer:
8 pieces of string
Step-by-step explanation:
Given that :
Total yards of string = 4
Length in yd of each string = 1/2 yards
Number of pieces of string Ms. Cole has :
Total. Yards / length in yard of each string
4 / (1/2)
4 * (2 /1)
= 8/1
= 8 pieces of string.

Step-by-step explanation:
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

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

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.
t + 1/4 = 2 7/12
what is t
plz help (6th grade)
Answer:
t = 2 1/3
