How is energy involved in physical change??
Answer:during phase chages
Step-by-step explanation:
During phase changes, energy changes are usually involved. For example, when solid dry ice vaporizes (physical change), carbon dioxide molecules absorb energy. When liquid water becomes ice, energy is released. Remember that all chemical reactions involve a change in the bonds of the reactants
its for science but its got math involved
its got to do with speed, time, and distance

Answer:
-23
Step-by-step explanation:
rearrange to point slope form first
slope can be fine by y2-y1/x2-x1 (im using the first 2 points)
so 13-25 = -12 and -54-(-72) = 18, and the slope is -12/18 which is -2/3
then you can use any point (i used the first point) to create the point slope form which is y-ypoint=slope(x-xpoint) and equation would be y-25=-2/3(x+72)
turn it into slope intercept form by multiplying -2/3 within the equation and adding -25 on both sides
you will get y= -2/3x-23
and the y intercept will be (0, -23)

Step-by-step explanation:
So if you know that 10 skeins makes 4 scarves... then 20 skeins makes 8 scarves (because you doubled it)
and if 10 skeins make 4 scarves... then half that number of skeins should make half the number of scarves... so 5 skeins makes 2 scarves
So we know that 20 skeins makes 8 scarves and 5 skeins make 2 scarves... all we have to do is add up the skeins and find we get 10 scarves
how do you do

Explain why we need to have a common denominator in order to add or subtract fractions.
Answer in paragraph form using complete sentences and include any calculations, graphs, and labeled diagrams as appropriate.
Answer
If you didn't it there wouldn't be an easy method to do the problem.Having the same denominator is the easiest method and is pretty basic.If you didn't have a common denominator such as:5/8 + 7/6, it would be virtually impossible to solve.

A forest covers 33,000 acres. A survey finds that 0.8% of a forest is old-growth-tree. How many acres of old-growth-trees are there?
Answer:
264 acres
Step-by-step explanation:
Since 33,000 acres is 100%, 330 acres is 1% because 33000 acres divided by 100 is 330 acres. Then if 330 acres is 1%, 33 acres is 0.1% because 330 acres divided by 10 is 33 acres. 1 divided by 10 is 0.1.
Next 33 acres times 8 because 0.8% is eight times bigger than 0.01%. This equals to 264 acres.

Quartiles are the values that divide a list of numbers into quarters: Put the list of numbers in order. Then cut the list into four equal parts. The Quartiles are at the "cuts"
...
Box and Whisker Plot
Quartile 1 (Q1) = (4+4)/2 = 4.
Quartile 2 (Q2) = (10+11)/2 = 10.5.
Quartile 3 (Q3) = (14+16)/2 = 15.
Answer:
The second 6
Step-by-step explanation:
So first quartile is the middle number in the beginning section after the middle number if that makes sense. The middle number is 10 so we break it into halves around that. The middle number in the first half is the second 6

Answer:
((ordinal date) +3) mod 7 = weekday number(IFC date) mod 7 = weekday numberno rule is possibleStep-by-step explanation:
a) Ordinal Calendar
The ordinal calendar numbers days of the year sequentially, so any given date is specified only by its day number: 1 to 366. In 2020, Jan 1 was a Wednesday, so the rule needs to be ...
day of week = ((ordinal date) +3) mod 7
This will give a result from 0 to 6. Those numbers map to days of the week as follows:
0: Saturday; 1: Sunday; 2: Monday; 3: Tuesday; 4: Wednesday; 5: Thursday; 6: Friday
__
b) International Fixed Calendar
The international fixed calendar has 13 months of 28 days. The first day of the year is always Sunday, so the day of the week is ...
day of week = (International Fixed Calendar date) mod 7
In 2020, there are two "leap days" that have day number 29. Days numbered 29 have no associated day of the week.
__
c) There is no rule that maps weekday to day of the year. (Each weekday is repeated many times (52 or 53) through the year, so there can be no functional relationship.)
