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.

Answer:

8. Conduction happens it transfers the heat when particles collide with each other. 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, than the pan which causes the particles to move at a uneven speed.

8 b. Convection.  During convection, the particles move. This happens only to liquids and gases particles because in solid objects the particles get stuck which doesn’t allow them to move around.

Answer:

2 x 36 + 3 or 2 x [tex]6^{2} +3[/tex]

Step-by-step explanation:

Three more must mean + 3.

The square of six is 36.

Twice the square of six is 36 times 2.

2 x 36 + 3 = 75

Answer:

d. -2/3

Step-by-step explanation:

To find the slope of a line, you need to find the [tex]\frac{rise}{run}[/tex] between two points.

[tex]\frac{rise}{run}[/tex] = [tex]\frac{-1-3}{6-0}[/tex]

     = [tex]\frac{-4}{6}[/tex]

     = -[tex]\frac{2}{3}[/tex]

     = -2/3

Using a system of equations, there are 9, 12 and 15 quarters, nickels and dimes respectively.

Creating a system of equations thus :

Substitute for n and q

(q+3) + (q+6) + q = 36

3q + 9 = 36

3q = 36 - 9

q = 27 ÷ 3

q = 9 quarters

n = 9 + 3 = 12 nickels

d = 9 + 6 = 15 dimes

Hence, there are 9, 12 and 15 quarters, nickels and dimes respectively.

Step-by-step explanation:

C. Because (0,-2) has a y that is 4 greater but the x is 4 greater and everything else is x+4 y+2

The graph is nonlinear, the correct option is, "Jenna, because the point (0, −2) does not lie on the straight line that contains the other points".

A linear function gives a graph that is a straight line. On the contrary, a nonlinear function gives a graph that is not a line.

Given are coordinates, (x, y) = (−12, −8), (−8, −6), (−4, −4) and (0, −2)

The graph of these coordinates is not linear, because (0,-2) has a y that is 4 greater and the x is also 4 greater and other points are (x+4, y+2)

Hence, the correct option is "Jenna, because the point (0, −2) does not lie on the straight line that contains the other points".

answer 32.395 pounds so 14.5 quarrs is 32.395 pounds

The approximate weight of 15.5 quarts of water will be 32.395 pounds.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that a quart of water weighs about 2.09 pounds. The weight of the 15.5 quarts of water will be:-

1 quart = 2.09 pounds

15.5 quarts  = 15.5 x2.09

15.5 quarts = 39.395 pounds

Therefore, the approximate weight of 15.5 quarts of water will be 32.395 pounds.

Answer:

7 2/3 + 5 1/3 = 13

How to do it:

First, you add 2/3 to 1/3 which is 1.

Then you add 7 and 5 which is 12.

And finally, you add the 1 to the 12 which is 13.

4 1/12 + (-5 1/3)=

Eliminate the negative and change the operation.

=4 1/12 − 5 1/3

Rewrite your equation with the parts separated.

=4 + 1 1/2 − 5 − 1/3

Solve the whole numbers.

4−5= −1

Solve the fractions.

1 1/2 − 1/3=?

Find the LCD of 1/12 and 1/3 and rewrite to solve the equivalent fractions.  (Least Common Denominator)

LCD = 12

1 1/2 − 4 1/2= −3 1/2

Reduce the fraction, 3/12.

−3 1/2 = −1/4

Combine the whole and fraction.

−1 − 1/4= −1  and 1/4
