A chef needs to choose a pan that will allow food to cook as quickly as possible for a special recipe and has decided that he will use one of three pans. Each pan has the same dimensions and design but is made of a different type of metal. The chef will design an experiment that will test and rank the thermal conductivity of the pans by cooking a hamburger patty to an internal temperature of 170 °F in each pan on the same stove burner. The thermal conductivity is the rate of transfer of energy in the form of heat over a period of time through a material.
Describe how thermal conductivity can be measured and compared for each of the pans.

Write an expression to represent the perimeter of the figure below.

Answers

Step-by-step explanation:

A perimeter is when you add up all of the sides

Here would be our equation

[tex]2(x+4)+2(2x-8)[/tex]

Answer: The expression for this would be 2(x+4) + 2(2x-8)

Step-by-step explanation:

This is because when we calculate perimeter, we add up all the sides. So, instead of doing (x+4)+(x+4), we can just do 2(x+4) and add up all sides. So, here’s the answer in simplest form!

B
50,000 * 20% =10,000
50,000+10,000= 60,000
The answer is b. (50,000x 20)/100 is 10,000. 50,000 + 10,000 equals 60,000.

Answer:

The larger angle is 144 degrees and the smaller angle is 36 degrees

Step-by-step explanation:

Because this is a  supplementary angle you have to find out what x is to solve  this equation [tex]2.4x+9.6x=180[/tex]

Because 2.4x and 9.6x are like terms we add them [tex]2.4x+9.6x=12x[/tex]

So now to find x we divide 180 by 12 to get 15  [tex]\frac{12x}{12} =\frac{180}{12}[/tex]

We replace the x with 15 [tex]2.4(15)+9.6(15)=36+144[/tex]

We add 36 and 144 which equals 180

A = small box of oranges

B = large box of oranges

3A + 14B = 203

11A + 11B = 220

Take the second equation and divide it by 11 as both A and B have the same coefficient, which will equal:

[tex]\frac{11A+11B}{11}[/tex] = A + B

220 will also have to be divided by 11, giving you 20

A + B = 20

You can cancel out 3A in the first equation by subtracting 3A + 3B = 60 from it.

11B = 143

143/11 = 13

B (large box of oranges) costs $13.

Substitute 13 for B back into one of our equations, in this case 3A + 3B = 60

3A + 3*13 = 60

3A + 39 = 60

3A = 21

A = 7

Thus:

A small box of oranges costs $7, and a large box of oranges costs $13.

−5.6x=−4

What is the solution to the equation?

Enter your answer as a simplified fraction in the box.

Answers

Answer: 0.714285

Step-by-step explanation:

The solution of the equation (-5.6 = -4) is (x = 5/7) and this can be determined by using the arithmetic operations.

Given :

-5.6x = -4

The following steps can be used in order to determine the solution to the equation (-5.6x = -4):

Step 1 - The arithmetic operations can be used in order to determine the solution to the given equation.

Step 2 - Write the given equation.

-5.6x = -4

Step 3 - Add 4 on both sides in the above equation.

-5.6x + 4 = -4 + 4

-5.6x + 4 = 0

Step 4 - Add 5.6x on both sides in the above expression.

-5.6x + 4 + 5.6x = 5.6x

4 = 5.6x

Step 5 - Divide 4 by 5.6 in the above expression.

[tex]x = \dfrac{4}{5.6}[/tex]

Step 6 - Simplify the above expression.

[tex]x = \dfrac{5}{7}[/tex]

Identify one point and the slope from the equation y + 4 = 1/3(x - 1)
Options:
m = 4 Point = (1/3, 1)

m = 1/3 Point = (1, -4)

m = 1/3 Point = (1, 4)

m = 1/3 Point = (-1, 4)

Answers

Answer:

m = 1/3 Point = (1, -4)

The slope is 1/3.

The point is 1,-4.

If you are wondering how I got the point, I just unsimplified the equation!

From y+4=1/3(x-1).

To y- -4=1/3(x-1).


The original formula is y-y1=m(x-x1). So we know where the y and the x is, and the slope.

Using the process PEMDAS I got the answer 10.

168÷2^3+3^3-20

There are no parentheses so you solve the exponents first.

168÷8+9-20

Next, we do not multiply which makes division our second step.

This gives us 21+9-20.

Now we add 21+9 which gives us the sum of 30.

30-20 is equal to 10.
