Answer:

$4162.4

Step-by-step explanation:

As per the question statement,

The computer monitors are in cuboid structure.

Width of computer monitors = 22 inches

Length of computer monitors = 22 inches

Thickness of computer monitors = 2 inches

Average cost of production per cubic inch = $0.43

To find:

Cost to the company to make 10 monitors.

Solution:

Volume of a cuboid is given as following:

[tex]Volume = Length \times Width \times Height[/tex]

Volume of one computer monitor as per the given dimensions = [tex]22\times 22 \times 2[/tex] = 968 cubic inches

Volume of 10 such monitors = 968 [tex]\times[/tex] 10 = 9680 cubic inches

Cost of manufacturing of 1 cubic inch = $0.43

Cost of manufacturing of 9680 cubic inch = $0.43 [tex]\times[/tex] 9680 = $4162.4

Answer:

Step-by-step explanation:

Distance ran last week = 26.1 miles

Since he wants to further on the total miles covered last week, then what is required is that total miles covered this week is greater than the total distance covered last week.

2.4 miles to the park ; 4 times around the park and 2.4 miles back from the park :

His coverage this week is should be represented by the Inequality :

2.4 + 4p + 2.4 > 26.1 ; which denotes that total coverage this week (2.4 + 4p + 2.4) is greater or more than last week's coverage of 26.1 miles

Answer:

He should use the greater than symbol, >. He would not beat his distance if he only ran 26.1 miles, so the greater than or equal to symbol would not be correct.

Step-by-step explanation:

the sum of interior angles in a triangle is 180°

so

2x+2+12x-8+6x+6=180

20x=180

x=180/20=9

so

m<A =6x+6=6*9+6=54+6=60

m<M=12x-8=12*9-8=100

m<N=2x+2=2*9+2=18+2=20

MAN is an obtuse triangle

because of 100° angle

Answer:

The solution of this system of linear equations is [tex](x,y) = (-3,-2)[/tex].

Step-by-step explanation:

Let be the following system of linear equations:

[tex]2\cdot x - 7\cdot y = 8[/tex] (1)

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

From (1) we clear [tex]y[/tex]:

[tex]2\cdot x -8 = 7\cdot y[/tex]

[tex]y = \frac{2\cdot x - 8}{7}[/tex]

And we apply this variable in (2):

[tex]-3\cdot x+2\cdot \left(\frac{2\cdot x -8}{7} \right)= 5[/tex]

[tex]-3\cdot x +\frac{4}{7} \cdot x -\frac{16}{7} = 5[/tex]

[tex]-\frac{17}{7}\cdot x = \frac{51}{7}[/tex]

[tex]x = -\frac{51}{17}[/tex]

[tex]x = -3[/tex]

And the value of [tex]y[/tex] is:

[tex]y = \frac{2\cdot (-3)-8}{7}[/tex]

[tex]y = -\frac{14}{7}[/tex]

[tex]y = -2[/tex]

The solution of this system of linear equations is [tex](x,y) = (-3,-2)[/tex].

Answer:

[tex]y\ge \:-1+x,\:y<\frac{4-x}{2}\quad :\quad \begin{bmatrix}y\ge \:-1+x\\ y<\frac{4-x}{2}\end{bmatrix}\quad \mathrm{Unbounded}[/tex]

The graph is attached below.

Step-by-step explanation:

Given the system of inequalities.

[tex]\begin{bmatrix}x-y\le \:1\\ x+2y<4\end{bmatrix}[/tex]

Isolate y for [tex]x-y\le \:1[/tex]

[tex]x-y\le \:1[/tex]

subtract x from both sides

[tex]x-y-x\le \:1-x[/tex]

simplify

[tex]-y\le \:1-x[/tex]

Multiply both sides by -1 (reverse the inequality)

[tex]\left(-y\right)\left(-1\right)\ge \:1\cdot \left(-1\right)-x\left(-1\right)[/tex]

simplify

[tex]y\ge \:-1+x[/tex]

now solving

[tex]x+2y < 4[/tex]

isolate y for [tex]x+2y < 4[/tex]

[tex]x+2y < 4[/tex]

subtract x from both sides

[tex]x+2y-x<4-x[/tex]

simplify

[tex]2y<4-x[/tex]

Divide both sides by 2

[tex]\frac{2y}{2}<\frac{4}{2}-\frac{x}{2}[/tex]

Simplify

[tex]y<\frac{4-x}{2}[/tex]

Graphing Method:

1. Graph each inequality separately

2. Choose a test point to determine which side of the line needs to be shaded

3. The solution to the system will be the area where the shadings from each inequality overlap one another.

Thus,

[tex]y\ge \:-1+x,\:y<\frac{4-x}{2}\quad :\quad \begin{bmatrix}y\ge \:-1+x\\ y<\frac{4-x}{2}\end{bmatrix}\quad \mathrm{Unbounded}[/tex]

The graph is attached below.

The solution to the equation given as 4(3x + 4) = 4x + 8 is x =-1

Expressions are mathematical statements that are represented by variables, coefficients and operators

The equation is given as

4(3x + 4) = 4x + 8

Open the bracket in the above equation

So, we have

12x + 16 = 4x + 8

Collect the like terms in the above equation

12x - 4x = 8 - 16

Evaluate the like terms in the above equation

8x = -8

Divide both sides by 8 in the above equation

x =-1

Hence, the solution to the equation given as 4(3x + 4) = 4x + 8 is x =-1

Answer:

$65 ≤ x ≤ $135

Step-by-step explanation:

Now, one should know the meaning of compound inequality. A compound inequality is an inequality that simply combines the two simple inequalities.

Now, in an inequality, three relations are performed, equal to, less than, and greater than. You can combine 'equal to' with 'less than' or 'greater than' according to the situation given.

Notice that in the given sign

≤

the value on the left side of the pointed side will be small or lesser than the value on the right side. Also notify that if inverted, like this ≥

The value of the left side will be greater. This means the value at the pointed side will always be smaller. The lower bar is a sign of equal to

if this is written

x ≤ 3

It means that x can be equal to three or any value less than 3 means 2,1,0,-1, etc.

Now in the question given, it is stated that money should be not less than $65 means it can either be $65 or more but not less than it. Let's assume 'x' as the amount required,

So one inequality is

$65 ≤ x

The second condition which is amount should be no more than $135, means it can be $135 or less, so inequality is

x ≤ $135

Remember that we use AND in the answer because both statements of inequality need to be fulfilled or satisfied.

Following are the solution to the given question:

Step-by-step explanation:

In question 1:

[tex]\to \frac{x^2+5x+6}{x+2}\\\\\to \frac{x^2+(3+2)x+6}{x+2}\\\\\to \frac{x^2+3x+2x+6}{x+2}\\\\\to \frac{x(x+3)+2(x+3)}{x+2}\\\\\to \frac{(x+3) (x+2)}{x+2}\\\\\to (x+3)[/tex]

In question 2:

[tex]\to \frac{2x+8}{x^2+5x+6}\\\\[/tex]

[tex]\to x^2+5x+6=0\\\\\to (x+3)(x+2)=0\\\\\to x+3 =0 \ \ \ \ \ \ x+2 =0\\\\\to x = -3 \ \ \ \ \ \ x=-2 \\\\[/tex]

[tex]\to f(x) = \frac{x-3}{x+5}\\\\\to f(x) \neq 0\\\\when\\\to x+5=0\\\\\to x=-4 \ excluded \ value \\\\\to x \neq 5[/tex]

In question 4:

[tex]\to f(x) = \frac{x^2+6x+8}{(x+4)}\\\\\to f(x) = \frac{x^2+(4+2)x+8}{(x+4)}[/tex]

[tex]\to f(x) = \frac{x^2+4x+2x+8}{(x+4)}\\\\\to f(x) = \frac{x(x+4)+2(x+4)}{(x+4)}\\\\\to f(x) = \frac{(x+4)(x+2)}{(x+4)}\\\\\to f(x) = x= -4 and -2[/tex]

In question 5:

Answer:

m∠DBC is 43°

Step-by-step explanation:

Let us solve the question

∵ D is in the interior of ∠ABC

→ That means D divides ∠ABC into two angles ABD and DBC

∴ m∠ABD + m∠DBC = m∠ABC

∵ m∠ABD = (3x + 5)°

∵ m∠DBC = (5x - 7)°

∵ m∠ABC = 78°

→ Substitute them in the equation above

∴ 3x + 5 + 5x - 7 = 78

→ Add the like terms in the left side

∵ (3x + 5x) + (5 + -7) = 78

∴ 8x + -2 = 78

∴ 8x - 2 = 78

→ Add 2 to both sides

∴ 8x -2 + 2 = 78 + 2

∴ 8x = 80

→ Divide both sides by 8

∴ x = 10

→ To find m∠DBC, substitute x by 10 in its measure

∵ m∠DBC = 5(10) - 7

∴ m∠DBC = 50 - 7

∴ m∠DBC = 43°

Answer:

x=20

Step-by-step explanation:

By the Triangle Sum Theorem, the angles of a triangle add up to 180. So we can set up the equation like this:

2x-10+70+4x=180

Combine Like terms

6x+60=180

Subtract 60 from both sides

6x=120

Divide by 6 to isolate the variable

x=20

Answer:x= 20

Step-by-step explanation:

As the equation of three angles of a triangle is 180°,

Then, 2x-10+70+4x=180

6x=120

So,x= 20
