To convert 5.5 cm to mm, we multiplied the length in centimeters by 10, which gave us 55 mm.

Measurement is an essential concept in mathematics and science that involves determining the size, quantity, or degree of something. The metric system is a standard measurement system that is widely used worldwide, and it includes units such as centimeters and millimeters.

Now, let's move on to your question about converting 5.5 cm to mm. Centimeters and millimeters are both metric units of length, with millimeters being smaller than centimeters. Therefore, to convert from centimeters to millimeters, we need to multiply the measurement in centimeters by 10.

We know that 1 cm is equal to 10 mm. So to convert 5.5 cm to mm, we can use the formula:

5.5 cm × 10 mm/cm = 55 mm

Therefore, 5.5 cm is equivalent to 55 mm.

It's important to note that when measuring, it's essential to use the appropriate units to get accurate results. In this case, we used the millimeter unit, which is suitable for measuring small lengths, to convert the 5.5 cm to a smaller unit, millimeters.

To find the OGF for the number of ternary sequences in which any occurrence of 2 has a 1 both immediately before and immediately after it, we can use a recursive approach.

Let A(x) be the OGF for sequences that start with a 1 and end with a 1. And let B(x) be the OGF for sequences that start with a 1, contain a 2, and end with a 1.

We have A(x) = x + \(x^{2}\) + \(x^{3}\) + \(x^{4}\) + ...

And B(x) = x * \(A(x)^{2}\), since a 2 can only appear after a 1 and must be immediately followed by another 1.

Finally, the OGF for the desired sequence is B(x) = x * x + \(x^{2}\) + \(x^{3}\) + \(x^{4}\) + ...)^2 = x * \(A(x)^{2}\)

So, the OGF for the number of ternary sequences in which any occurrence of 2 has a 1 both immediately before and immediately after it is x * ( x + \(x^{2}\) + \(x^{3}\)......)^2.

Answer:

His speed is 2 m/s

His velocity is 0 m/s

Step-by-step explanation:

I'll assume the question is

Kia was 200 m north of the Library when he remembered he had to return some books to the library it took him to 200 seconds to do the round-trip which best describes hist round-trip.

Kia's distance from the Library is 200 m

the round-trip took him 200 s

The total distance for the round trip = 200 x 2 = 400 m

His displacement for the round trip = 0 m (since he returns to his original position)

His speed = distance/time = 400/200 = 2 m/s

His velocity = displacement/time = 0/200 = 0 m/s

Answer: 8,000

Step-by-step explanation:

If the scale model can only hold 1 gallon of oil but the full size truck needs to hold 8,000 gallons, you can find a relevant scale factor using cross multiplication:

The volume of the cone is 1005.3 cubic centimeters. The curved surface area of the cone is 301.6 square centimeters.

a) The volume of the cone is 1005.3 cubic centimeters.

To calculate the volume of a cone, we use the formula V = (1/3)πr²h, where V represents the volume, π is approximately 3.14159, r is the radius of the base, and h is the height of the cone. By substituting the given values, we get V = (1/3) × 3.14159 × 6² × 8 = 1005.3 cubic centimeters.

b) The curved surface area of the cone is 301.6 square centimeters.

To determine the curved surface area, we use the formula A = πrl, where A represents the curved surface area, π is approximately 3.14159, r is the radius of the base, and l is the slant height of the cone. The slant height can be found using the Pythagorean theorem: l² = r² + h². Substituting the given values, we have l² = 6² + 8² = 100, resulting in l = 10. Plugging these values into the formula, we get A = 3.14159 × 6 × 10 = 301.6 square centimeters.

Answer:

The people with the membership take seven classes

The people without the membership take five classes

Step-by-step explanation:

As it says in the picture:

"A local gym has two different fees for their yoga classes. Members of the gym are charged a one-time membership fee of $25 and pay $5 per yoga class. Nonmembers do not pay a membership fee, but they pay $7 per class. How many yoga classes do nonmembers and members have to attend for their cost to be the same?"

First, what you would do is look for your key words in the sentence. What you'd take from the sentence is everything that I highlighted.

If the membership fee is $25 and yoga classes are $5 and nonmembers cost for yoga classes is $7 then you have your problem right there.

Next, what you would look for is your Greatest common divisor. (GCD) The GCD of 5 and 7 is 5 of course. So now what you would do is find out how many times 5 and 7 goes into five.

7 x 5 = 35

5 x 5 = 25

Now what you do is ask yourself the question, "How many times does the nonmembers and members have to go to class to have the same amount of money spent?"

Now I will answer this question for you.

five dollars for members.

seven dollars for nonmembers.

Your answer is: 7 x 5 (30)

The  extraneous solution of the equation is as follows:

y = -4 or y = 2

Let's find the extraneous solution of the equation as follows:

1 - y = √2y² - 7

square both sides of the equation

(1 - y)² = (√2y² - 7)²

(1 - y)(1 - y) = 2y² - 7

Open the bracket of the left side of the equation

Hence,

1 - y - y + y² = 2y² - 7

1 - 2y + y² = 2y² - 7

y² - 2y + 1 = 2y² - 7

2y² - y²  + 2y  - 7 - 1 = 0

y² + 2y - 8 = 0

y² - 2y + 4y - 8 = 0

y(y - 2) + 4(y - 2) = 0

Given:

Deandre is choosing between two exercise routines.

Routine #1:

Walking = 22 calories

Running = 12.5 calories

Routine #2:

Walking = 43 calories

Running = 8.3 calories

Here we need to find the amount of time spent on running in routine #1 burn at most as many calories as routine #2.

For that, we have to find the inequality,

So, let us consider t is the number of minutes spent running.

So,

Routine #1 = 22 + 12.5t

Routine #2 = 43 + 8.3t

Here we know that, In Routine #1 to burn at most as many calories as Routine #2 means that Routine #1 would burn less than or equal to as many calories as Routine #2.

An essential concept in mathematics and can be applied to a variety of fields such as physics, economics, and engineering.

The slope of a line in a Cartesian plane is a numerical representation of its steepness and inclination relative to the x-axis.

The slope of a straight line refers to the rise or fall of the y-coordinate as it moves from left to right along the x-axis.

There are a few different ways to interpret the slope of a line, but generally it can be thought of as the rate at which the dependent variable changes with respect to the independent variable.
When the slope is positive, the line rises from left to right, indicating that the dependent variable is increasing as the independent variable increases.

In other words, there is a direct relationship between the two variables.

Conversely, when the slope is negative, the line falls from left to right, indicating that the dependent variable is decreasing as the independent variable increases.

This means that there is an inverse relationship between the two variables.
The magnitude of the slope can also provide information about the relationship between the variables.

If the slope is close to zero, then the relationship between the two variables is weak or nonexistent.

However, if the slope is large in magnitude (i.e. close to 1 or -1), then there is a strong relationship between the variables.

A slope of zero indicates that there is no change in the dependent variable as the independent variable changes, while a slope of undefined means that the line is vertical and has no slope.
