You are working with cable that has a loss rate of 5 dB per 100 ft. If you don’t want to lose more than 15 dB, what is the maximum number of feet of cable you can run

Answer:

this can be simplified

12v + 10v + 14 = 80

22v + 14 = 80

22v = 66

v = 3

Answer:

v = 3

Step-by-step explanation:

12v + 10v = 22v

22v + 14 = 80

Subtract 14 from both sides.

80 - 14 = 66

22v = 66

now divide both sides by 22

66/22 = 3

v = 3

Answer:

$38

Step-by-step explanation:

Answer:

[tex]x \ge3.5[/tex]

Step-by-step explanation:

First, write the given in the form of a mathematical equation rather than words. I'll call the mystery number given in the question [tex]x[/tex]:

[tex]\frac{5*7}{x} \leq 10[/tex]

Simplify:

[tex]\frac{35}{x} \leq 10[/tex]

Solve for x:

[tex]\frac{35}{x} *x\leq 10*x[/tex]

Simplify the fraction:

[tex]35\leq 10x[/tex]

Divide by 10 to isolate x:

[tex]\frac{35}{10} \leq x[/tex]

Flip the equation around to make it easier to read:

[tex]x \ge \frac{35}{10}[/tex]

Simplify the fraction:

[tex]x \ge \frac{7}{2}[/tex] or [tex]x \ge3.5[/tex]

Answer:

Assuming the number is 9.094 the answer is 9.094 If it is whole number it is 9000

Step-by-step explanation:

The tens place is             .0

The Hundreds place is   .09

The thousands place is   .094

if you are talking about whole numbers: it's 9000

When rounding, 5 and above it is rounded up, and 4 and below is rounded down.

So for this problem you only need to look one place to the right.

9094 Because that number is 0 that means you round down.

Answer:

(x - 8) + (2x - 4) = 15

3x - 12 = 15

+12       +12

3x = 27

Divide by 3 on both sides:

x = 9

Answer:

x = 9

Step-by-step explanation:

➼first, let's put it into an equation

(x - 8) + (2x - 4) = 15

➼next, add up the common terms

-since there are two variables with x and two number variables, we will rewrite the equation and solve

(-8 - 4) + (2x + x) = 15

-8 - 4 = -12

2x + x = 3x

plug in:

-12 + 3x = 15

➼now get x alone by first getting rid of 12

-do this by doing opposite and adding 12 to everything

-12 + 12 = 0

12 + 15 = 27

plug in:

3x = 27

divide 3 both sides

27/3 = 9

3/3 = 0

➼x = 9

Answer:2

Step-by-step explanation:14/2 = 7 - 5 =2

First, let's define our variable

x = brother's money

Now, let's create an equation to model the problem.

$14 = 2x - $5

Add 5 to both sides.

$19 = 2x

Divide both sides by 2

$9.5 = x

His brother has $9.5

Answer:

D. 4

Step-by-step explanation:

Without actually solving the equation, recall that for [tex]a=|b|[/tex], there are two cases:

[tex]\begin{cases}a=b, \\a=-b\end{cases}[/tex]

In the given equation [tex]|x-2|^{10x^2-1}=|x-2|^{3x}[/tex], there are two pairs of absolute value symbols.

Since each has two cases, there must be a total of [tex]2\cdot 2=\boxed{4}[/tex] different equations created.

All four cases are:

[tex]\begin{cases}(x-2)^{10x^2-1}=(x-2)^{3x},\\(-x+2)^{10x^2-1}=(x-2)^{3x},\\(x-2)^{10x^2-1}=(-x+2)^{3x},\\(-x+2)^{10x^2-1}=(-x+2)^{3x}\end{cases}[/tex]

Exponents differ, hence clearly there are four possible solutions to this equation.

You can solve for all four values of [tex]x[/tex] by taking the log of both sides and using a bit of algebra to verify you have four solutions.

9 test

Step-by-step explanation:

There should be 9 administrators chosen.

A proportion is a comparison of two numbers that each represent the parts of a whole.

Given that, A supervisor wants to know the average number of hours worked by employees in a factory. There are 18 managers, 240 labourers, and 54 administrators. Three managers are chosen to participate in the survey.

Since, the manager chosen 3 out of 18 managers, hence, the proportion is 1 to 6 persons,

Therefore, when he is choosing administrators, 54/6 = 9

Hence, there should be 9 administrators chosen.

Answer:

[4, ∞)

Step-by-step explanation:

The range of a graph is the values of y for that graph.

We can see that the lowest y value of the graph occurs at the minimum, (0, -4). So the lower limit of the range is -4.

On the right side, the graph continues to reach upward indefinitely. That means that we can say that the upper limit of the range is infinity.

We can write this in different forms. I will write it here in interval notation:

[4, ∞)

The "[" signifies that the value of -4 is included in the range, and the ")" signifies that the range goes up to infinity.

5.9x3.3=19.47

i am glad to help you have a good day:) stay safe.

The value of the perimeter of the square become is 23.6x - 13.2.

Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.

The perimeter of a square is defined as the addition of the lengths of the square.

The perimeter of a square = 4a

Where a is the length of the side of the square

The perimeter of a square = 4a

Here a = 5.9x-3.3

Substitute the value of a = 5.9x - 3.3 in the formula, and we get

Perimeter of square = 4(5.9x - 3.3)

Perimeter of square = 23.6x - 13.2

Therefore, the value of the perimeter of the square become 23.6x - 13.2.
