8. Conduction. (Conduction is the transfer of heat that happens when particles collide with each other. It can happen in solids, liquids, and gases.)
Before the pan is placed on the burner, its particles are moving at the same average speed. The whole pan is at the same temperature. The hot burner is at a much higher temperature. In other words, the particles that make up the burner are moving at a greater average speed and therefore have greater thermal energy.
8b. Convection. During convection, however, the particles themselves move. This happens only in liquids and gases because the particles in solids are stuck in place and cannot move.

The whole pan is at the same temperature. The hot burner is at a much higher temperature, than the pan which causes the particles to move at a uneven speed.

Answer: 27/8 or 3 3/8
Step-by-step explanation:
For this problem, you can simply plug the side length, 2 1/2, into the variable, s. Let's change it to an improper fraction to make it an easier process. Plugging in the number would be: V=3/2^3. This would be translated to 3/2 x 3/2 x 3/2. Multiply them and you'll get 27/8 or 3 3/8.
Jaiden is ordering 2.615, 2.65, 2.7, and 2.623 from least to greatest. Here are his steps:
(1) Compare and order 2.7 and 2.65 because they have the fewest digits.
(2) Compare each digit of the numbers 2.615 and 2.623.
* The units digits are equal.
* The tenths digits are equal.
* 1 < 2 in the hundredths place so 2.615 < 2.623.
(3) Combine the two lists into one: 2.7, 2.65, 2.615, 2.623.
Which statement describes Jaiden’s error?
Jaiden listed the numbers from greatest to least.
Jaiden should have compared the two numbers with the most digits first.
Jaiden should have added zeroes to each of the shorter decimals to get 2.615, 2.065, 2.007, and 2.623. Then, he should have compared all of them using place value.
Jaiden should have added zeroes to the ends of the shorter decimals to get 2.615, 2.650, 2.700, and 2.623. Then, he should have compared all of them using place value.

A. 3,600
B. 1,600
C. 600
D. 2,400
(sorry the image didn't show up, and percentage of grey is 15%)
Answers
The total number of gallons of paint sold was 1600.
What is percentage?A percentage is a fraction of an amount expressed as a particular number of hundredths of that amount.
Given that, 240 gallons of gray paint were sold last year, which is 15% of total sold paint.
Let the total numbers of gallons of paints sold be x,
15% of x = 240
x = 240*100/15
x = 1600
Hence, the total number of gallons of paint sold was 1600.

Paulo tracks his commute time. The coordinate plane below shows some of his commute times in the last two weeks. The x-axis of the graph represents the number of days before today. For example, -1 would represent yesterday. The y-axis represents the commute time in minutes.
2 days ago, Paulo's commute time was halfway between his commute times 8 and 9 days ago.
At what coordinates should Paulo graph his commute time 2 days ago?
Answers
Answer:
-2 Means Day 2 & 21 is commute time
Step-by-step explanation:
The coordinate plane below shows some of his commute times in the last two weeks.
See attached graph
Yesterday means - 1
Days 8 means - 8
Day 9 means -8
- 8 has dot on 24 => Commute time on Days 8 = 24 minutes
-9 has dot on 18 => Commute time on Days 9 = 18 minutes
2 days ago, Paulo's commute time was halfway between his commute times 8 and 9 days ago.
=> Commute time on Days 2 =(24 + 18)/2 = 21
Day 2 = - 2
Coordinate = (-2 , 21 )
-2 Means Day 2 & 21 is commute time
Find a polynomial, which if substituted for M will make the equation an identity: (4c^4–7c^2+6)–M=0
Answers
-3c^2+6
Step-by-step explanation:
The equation will be identity (0=0) when M is equal to the contents of the parentheses. That polynomial can be used directly, or it can be simplified by combing the c^2 terms.
The contents of parentheses simplify as follows: (4c^2 - 7c^2 +6)=(c^2(4 -7)+6)=(-3c^2 +6)

Answers
Answer:
x = 2
Step-by-step explanation:
4x + 5 + 5x + 6= 29 combine like terms
9x + 11 = 29 subtract 11 from both sides
9x = 18 divide both sides by 9 to get x by itself
x = 2
Hope this helped!! :)
Answer:
X=2
Step-by-step explanation:
Start by adding the numbers without x by them. 5+6=11. Put that to the side.
Then, add the numbers with the x by them. 4x+5x=9x. Put that to the side.
Now you have 11+9x=29. To find x, now you want to subtract 11 by both sides to single out the variable. 11-11=0, 29-11=18. Now you're left with 9x=18.
Last, you divide 18 by 9 to get X=2.
