Step-by-step explanation:

Answer:

We can set up the following equation:

Excel Cable Company fee = Best Cable Company fee

32 + 8x = 26 + 10x

Here, x represents the number of premium channels. We can solve for x by subtracting 26 from both sides and then dividing both sides by 2 to get:

6 + 6x = 10x

6 = 4x

x = 6/4

x = 1.5

Therefore, the total monthly subscription fee for the Excel and Best cable companies will be the same for 1.5 premium channels. Note that this is not a whole number, so it is not possible for the subscription fees to be the same for a whole number of premium channels

Answer: 3 channels

Step-by-step explanation:

The ECC has an initial fee of $32.00 with a $8.00 fee for each channel, so we can label that as Total = 8(x) + 32.00.

The BCC has an initial fee of $26.00 with a $10.00 fee for each channel, so we can label that as Total = 10(x) + 26.00.

Since we want to find how many premium channels each company needs till the monthly subscription rate will be equal, we can set those equal to eachother.

8x + 32.00 = 10x + 26.00

2x = 6

x = 3, so when each company has 3 premium channels used, the prices will be the same.

The appropriate number of significant figures for the calculation of 7.5 + 2.26 + 1.311 + 2 is equivalent to 10.

Significant figures:

Any non-zero number is significant. The number 33.2 has 3 significant digits because all digits present are non-zero.

Zeros between two non-zero numbers are valid. 2051 has 4 significant digits. Zero is between 2 and 5.

For numbers in exponential notation:

N x 10x, all numbers spanning N are valid. "10" and "x" are not important. 5.02 x 10^4 has 3 significant digits.

"5.02." "10" and "4" are not important.

Provides the ability to change the precision of a value by manipulating its shape. For example, write 1100 with 3 significant digits. 1100 has 2 significant digits. The trailing two zeros are not significant. Adding a decimal at the end brings the number to the 1100th significant digit (according to rule 5).

We can create a 3-significant digit of 1.10 x 10^3.

In the question of adding all we get,

7.5 + 2.26 = 9.76

9.76 + 1.311 + 2

9.76 + 1.311 = 11.071

11.071 + 2

11.071 + 2 = 13.071

13.071

Round 13.071 → 13

This is because the total sum of the numbers gives a value of 13.071.

However, the number '2' has only one significant figure.

Therefore, we need to restrict our solution to one significant figure.

Therefore, on rounding off the solution becomes '10' with only one significant figure.

104 degrees is the measure of angle U.

A circle is a shape consisting of all points in a plane that are at a given distance from a given point, the centre.

Given that a  quadrilateral STUV is inscribed in circle W

We need to find the measure of U.

A quadrilateral is a four-sided polygon, having four edges and four corners.

In quadrilateral the sum of opposite angles should be equal to 180 degrees.

Let the measure of U is x.

∠S+∠U=180

76+x=180

Subtract 76 from both sides

x=180-76

x=104

A quadratic equation is a polynomial equation in one unknown that contains the second degree, but no higher degree, of the variable.

The standard form of a quadratic equation is ax² + bx + c = 0, when a ≠ 0.

Let's solve for x in the quadratic equation 2x² – 28x = –98.

2x² – 28x = –98

2x² – 28x + 98 = 0

The angle bisector in geometry is the ray, line, or segment which divides a given angle into two equal parts.

m∠ABX = 2y+10, and m∠ABC = 10y-4

Now, m∠ABC = m∠ABX + m∠XBC

m∠ABX = m∠XBC

To find the product of 5 x 10^3 and 9 x 10^7, we need to multiply the two numbers. The first step is to multiply the two numbers without the exponents, which gives us 5 x 9 = 45. Next, we need to add the exponents to find the exponent of the final product. 10^3 and 10^7 have exponents of 3 and 7, respectively, so the final exponent is 3 + 7 = 10. This means that the final product is 45 x 10^10, or 4.5 x 10^11 in standard form.

The symbol ∠ is used to denote an angle. The symbol m ∠ is sometimes used to denote the measure of an angle.

x = 15

∠H = 82

∠I = 49

∠G = 49

Note that side HG and side HI are congruent ( indicated by the little dashed line ) which means that their opposite angles are congruent ( ∠I and ∠G to be more specific. )

Angles in a triangle add up to equal 180°

Hence, 3x + 37 + 2 ( 4x - 11 ) = 180 ( note that the 2 in 2(4x - 11) came from angles I and G being congruent )

We now solve for x

3x + 37 + 2 ( 4x - 11 ) = 180

step 1 distribute the 2 to the 4x and -11

2 + 4x = 8x

-11 * 2 = -22

we now have 3x + 37 + 8x -22 = 180

step 2 combine like terms

3x + 8x = 11x

37 - 22 = 15

we now have 11x + 15 = 180

step 3 subtract 15 from each side

15 - 15 cancels out

180 - 15 = 165

we now have 11x = 165

step 4 divide each side by 11

11x / 11 = x

165 / 11 = 15

we're left with x = 15

Our final step is to find the measures of ∠G, ∠H and ∠I

We can do this by simply replacing x with 15 in their given expression

∠H = 3x + 37

* substitute 15 with x *

3 ( 15 ) + 37

3 * 15 = 45

45 + 37 = 82

Hence, ∠H = 82

∠I = 4x - 11

* substitute x with 15 *

4(15) - 11

4 * 15 = 60

60 - 11 = 49

For an initial Bacteria population of 8000 to reach 12000 bacteria it will take almost 4 hours.

Bacterial culture growth is defined as an increase in the number of bacteria within a population rather than an increase in the size of individual cells. Bacterial population growth occurs geometrically or exponentially. In each cycle of division (generation), the cell develops into 2 cells, then 4 cells, then 8 cells, then 16 cells, then 32 cells. The time required for generation formation, generation time (G), can be calculated using the following formula:

G = 1/n = [tex]\frac{t}{3.3logb/B}[/tex]

where B is the number of bacteria at the start of observation, b is the number of bacteria present after period t, and n is the number of generations. This relationship indicates that the average generation time is constant and the rate of bacterial population growth is proportional to the number of bacteria at any given time point. This relationship holds only during periods of exponential population growth called logarithmic growth.

According to the question:

2^(t/6) = 12000/8000 = 1.5

What is reflection:

A reflection is referred to as a flip in geometry. A reflection is the shape's mirror image. A line, called the line of reflection, will allow an image to reflect through it. Every point in a figure is said to reflect the other figure when they are all equally spaced apart from one another. The reflected image should be the same size and shape as the original, but it faces the opposite way. Changes in position during reflection may also result in translation. Pre-image and image are terms used to refer to the same thing in this context.

A(-4, 1)→(-4, -1)

We can see that each x-coordinate is 1 lower and each y-coordinate is 1 higher than the image points by comparing these points to the points in DEF. This means that we should translate 1 unit to the right and 1 unit to the bottom to subtract 1 from each x-coordinate and 1 from each y-coordinate.
