Most thermal conductors are made up of metal material.

We have to determine, most thermal conductors are made of which material?

According to the question,

It is one of the three concepts by which heat and energy can be transferred from one place to the other within a material or from one material to another.

Conduction occurs by direct contact whereas Convection occurs by movement or flow of heat.

Radiation on the other hand occurs with the help of electromagnetic waves.

Conduction mostly occurs in metals and the conductivity of metal is different from one another.

When it comes to the best metal for thermal conductivity, ideally it is Silver but Copper is used instead.

The reason for it is that Silver is too expensive and is infeasible to use. Copper, on the other hand, is available in abundance, is affordable, and can be used in any application.

Hence, Most thermal conductors are made up of metal material.

Answer:

y = 1/6x - 8/3

Step-by-step explanation:

The equation of a line in slope-intercept form is.

y = mx + b

where m represents the slope and b, the y-intercept.

Rearrange y + 2 = 1/6 (x - 4)  into this form

distribute bracket and simplify.

y + 2 = 1/6x - 2/3

⇒ y = 1/6x - 2/3 - 2

⇒ y = 1/6x - 8/3 ← in slope-intercept form

Answer:

n = 35

Step-by-step explanation:

n - 13 x -2 = -44

distribute:

(n x -2) - (13 x -2) = -44

-2n - (-26) = -44

two negatives in front of a number makes it a positive number

so rewrite -2n + 26 = -44

-2n = -44 -26

-2n = -70

n = [tex]\frac{-70}{-2}[/tex]

n = 35

calc check (35 - 13) x -2 = 22 x (-2) = -44

Answer:

The shortest side of the fence can have a maximum length of 80 feet

Step-by-step explanation:

Inequalities

To solve the problem, we use the following variables:

x=length of the longer side

y=length of the sorter side

The perimeter of a rectangle is calculated as:

P = 2x + 2y

The perimeter of the fence must be no larger than 500 feet. This condition can be written as:

[tex]2x + 2y \le 500[/tex]

The second condition states the longer side of the fence must be 10 feet more than twice the length of the shorter side.

This can be expressed as:

x = 10 + 2y

Substituting into the inequality:

[tex]2(10 + 2y) + 2y \le 500[/tex]

This is the inequality needed to determine the maximum length of the shorter side of the fence.

Operating:

[tex]20 + 4y + 2y \le 500[/tex]

Simplifying:

[tex]20 + 6y \le 500[/tex]

Subtracting 20:

[tex]6y \le 500 - 20[/tex]

[tex]6y \le 480[/tex]

Solving:

[tex]y \le 480 / 6[/tex]

[tex]y \le 80[/tex]

The shortest side of the fence can have a maximum length of 80 feet

Answer:

10

Step-by-step explanation:

Let the number of blue balls be x.

Number of red balls = 5

Total number of balls = x + 5

P (getting a red ball)  = 5/x+5

P (getting a blue ball)  = x/x+5

Given that

2(5/x+5) = x/x+5

10(x+5) = x^(2) +5x

x^(2)-5x-50=0

x(x-10)(x+5)

Now either x-10 = 0 or x+5= 0

But number of balls cannot be negative.

Hence, the number of blue balls is 10.

Answer:

3 + x

Step-by-step explanation:

Sum means to add, so you would just add 3 and x (since they haven't given an actual number and only a variable).

The sum of the number 3 and the variable x will be (x + 3).

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

In the linear expression, the degree of the variable is one.

The sum of 3 and a number x.

Then the expression will be

⇒ 3 + x

The number 3 is a constant number and the term x is a variable.

The expression (x + 3) is a linear expression because the degree of the expression is one.

The number of the variable is one, then the expression is linear expression of one variable.

Thus, the sum of the number 3 and the variable x will be (x + 3).

Answer:

Because, the situation is going up, the integer is +12 or 12.

Answer:

The caterer charged $50 for an adult's meal and $13 for a child's meal

Step-by-step explanation:

Let the cost of an adult meal be $x

and the cost of a child meal be $y

From the question,

Manny plans to have 66 adults and 27 children and the total cost of his meals is $3,651.

We can write that

66x + 27y = 3651 ...... (1)

Also, from the question,

Zack has 77 adults and 43 children and the total cost he will pay the caterer is $4,409.

We can also write that

77x + 43y = 4409 ...... (2)

Multiply equation (1) by 7, so that we get

462x + 189y = 25557 ...... (3)

Multiply equation (2) by 6, so that

462x + 258y = 26454 ...... (4)

Now, subtract equation (3) from equation (4), so that

69y = 897

∴ y = 897/69

y = 13

Put the value of y into equation (1) to get x

66x + 27y = 3651

∴ 66x + 27(13) = 3651

66x + 351 = 3651

66x = 3651 - 351

66x = 3300

x = 3300/66

x = 50

Therefore,

The cost of an adult's meal is $50

and the cost of a child's meal is $13

Hence, the caterer charged $50 for an adult's meal and $13 for a child's meal.

Answer:

300 grams of carbohydrates are recommended per day

Step-by-step explanation:

First, convert 12% daily value into decimal: 12/100=0.12

Since this is a word problem and we have 36 grams and 12% daily value, we should make an equation first.

We are looking for how many grams of carbs should be taken a day, so lets use x as the unknown. We need to find x!

0.12 x= 36 g

Now: divide 36 grams by 0.12

x= 36g/0.12= 300g

x= 300 grams of carbohydrates are recommended per day.

Answer:

D) (-5, - 7)

Step-by-step explanation:

Because both lines intersect, they must share a point (have same x and y coordinates).

[tex]2x + 3 = - 4x - 27[/tex]

[tex]2x = - 4x - 30[/tex]

[tex]6x = - 30[/tex]

[tex]x = - 5[/tex]

Substite x for - 5 in any of the equations to find the y coordinate.

[tex]y = 2( - 5) + 3 [/tex]

[tex]y = - 10 + 3[/tex]

[tex]y = - 7[/tex]

The x coordinate for the intersection point is - 5 and the y coordinate is - 7. The intersection point is (-5, - 7)

Answer:

n= -10

Step-by-step explanation:

-66=7n+4

-7n=4+66

-7n=70

n=70/-7

n= -10

Answer:

n = -10

Step-by-step explanation:

-66 = -9n + 16n + 4

1. I started by subtracting 4 on both sides of the equation this gives you -70 = -9n + 16n

2. I then combined the like terms 16n and -9n on the right side of the equation. We do this by subtracting 9n from 16n. Which gives you -70 = 7n

3. We then divide both sides by 7 in order to get -10 = n

This gives you your final answer of n = -10
