XYZ Tech wants to sell at least 40% more tablets this week than the 50 they sold last week. Which inequality describes this?

A. x ≥ 1.4(50) B. x > .4(50) C. x > 1.4(50)

Answer:

c (c - 8)

Step-by-step explanation:

c² - 8c

First, you have to find the GCF

The Greatest Common Factor is the factor that all have in common. Here the GCF is c

So, we factor c out and has left (c - 8)

So, our equation is

(a) We can represent Kristin's height above the ground (in meters) when she has traveled 24.9 meters around the Ferris wheel as f(24.9).

(b) We can represent Kristin's height above the ground (in meters) when she has traveled 49.71 meters around the Ferris wheel as f(49.71).

(a) We have to determine how can we represent Kristin's height above the ground (in meters) when she has traveled 24.9 meters around the Ferris wheel.

We can create the a table and function to describe that statement but F(24.9) is the best representation of Kristin's height above the ground (in meters) when she has traveled 24.9 meters around the Ferris wheel.

(b) We have to determine how can we represent Kristin's height above the ground (in meters) when she has traveled 49.71 meters around the Ferris wheel.

The complete question is:

In the previous modules we developed formulas, tables, and graphs to represent how two varying quantities change together. For example, we considered how Kristin's height above the ground changed as her total distance traveled increased while riding a Ferris wheel.

We even assigned letters to represent the possible varying values each quantity can assume.

• Let d represent the distance Kristin has traveled (in meters) around the Ferris wheel starting at the bottom.

• Let h represent Kristin's height above the ground (in meters).

Note that the way we are thinking about this relationship is that we vary Kristin's distance traveled and observe what happens to her height above the ground.

What if you want to communicate information about her position after she traveled some number of feet? You could write it out in words, like "Kristin was 16.3 meters above the ground when she had traveled 23.7 meters around the Ferris wheel". However, that's a lot to have to write out, especially if you want to talk about multiple values. You could also draw a table or create a graph, but mathematicians developed a tool called function notation to help them represent values in a covarying relationship.

[Note: We will define the exact meaning of "function" later in this investigation. For now, just think of "function" as meaning the same thing as "relationship".]

First, we pick a letter to represent the name of the relationship. Let's call this relationship "f". Now, instead of saying "the relationship between Kristin's height above the ground (in meters) and her total distance traveled (in meters)" we can simply say "relationship f".

Also, we can use f(d) to represent values of Kristin's height above the ground (values of h). We read this as "f of d", and the parentheses here are just part of the notation. They do NOT indicate multiplication.

For example, f(13) represents Kristin's height above the ground (in meters) when she has traveled 13 meters around the Ferris wheel.

(C) It will take him the most time to snowball his payments based on the highest interest rate.

Customers (cardholders) are given a credit card, a sort of payment card, to enable them to pay a business for goods and services based on the amount of debt they have accrued (i.e., promise to the card issuer to pay them for the amounts plus the other agreed charges).

A revolving account is set up by the card issuer, which is frequently a bank or credit union and gives the cardholder access to a line of credit from which they can borrow money to make purchases or get cash advances.

Consumer credit cards and business credit cards are the two types of credit cards.

Most cards are made of plastic, but others are made of metal (stainless steel, gold, palladium, titanium), and some have jewels inlaid in the metal.

As a result, Fred currently owes money on four separate credit cards.

Paying off your lowest obligations first, then going on to the next smallest, and so forth, is known as snowballing.

The probability that the person reaches 10 before he reaches -5 is 0.475.

The probability of reaching 10 before reaching -5 in a random walk can be found using the concept of expected number of steps to reach a state. In this case, we can calculate the expected number of steps required to reach 10 and -5, and then compare the results.

E10 = 1 + 1/2 × E10 + 1/2 × E9

E9 = 1 + 1/2 × E10 + 1/2 × E8

Substituting the expression for E9 into the equation for E10, we get:

E10 = 1 + 1/2 × E10 + 1/2 × (1 + 1/2 × E10 + 1/2 × E8)

E10 = 1 + 3/4 × E10 + 1/4 × E8

Eliminating E10, we get:

E8 = 4 × (E10 - 1)

Substituting the expression for E8 into the equation for E10, we get:

E10 = 1 + 3/4 × E10 + 1/4 × 4 × (E10 - 1)

E10 = 20

So the expected number of steps to reach 10 is 20.

E-5 = 1 + 1/2 × E-4 + 1/2 × E-5

E-4 = 1 + 1/2 × E-5 + 1/2 × E-3

Substituting the expression for E-4 into the equation for E-5, we get:

E-5 = 1 + 1/2 × (1 + 1/2 × E-5 + 1/2 × E-3) + 1/2 × E-5

E-5 = 1 + 3/4 × E-5 + 1/4 * E-3

Eliminating E-5, we get:

E-3 = 4 × (E-5 - 1)

Substituting the expression for E-3 into the equation for E-5, we get:

E-5 = 1 + 3/4 × E-5 + 1/4 × 4 × (E-5 - 1)

E-5 = 26

So the expected number of steps to reach -5 is 26.

The probability of reaching 10 before reaching -5 is calculated by dividing the expected number of steps required to reach 9 (E9) by the expected number of steps required to reach 10 (E10). The reason for this is that the person will reach 9 after taking 19 steps, which is one step short of reaching 10. Hence, we can consider reaching 9 as an intermediate milestone before reaching 10.

P(10 before -5) = E9 / E10

Since the person has a 1/2 probability of moving one step in either direction, the expected number of steps required to reach 9 (E9) is given by:

E9 = 1 + 1/2 * E10 + 1/2 * E8

E9 = 1 + 1/2 * 20 + 1/2 * E8

E9 = 19/2

So, the probability of reaching 10 before reaching -5 is given by:

P(10 before -5) = E9 / E10

P(10 before -5) = 19/2 / 20

P(10 before -5) = 19/40

P(10 before -5) = 0.475

Step-by-step explanation:

In this problem, there are two angles with degrees of 2x + 6 and two angles of degrees of 15x - 8. We know the sum of the four angles is 360, as stated in the problem. Thus we can set up the following equation:

2(2x + 6) + 2(15x - 8) = 360

4x + 12 + 30x -16 = 360

34x - 4 = 360

34x = 364

x ≈ 10.7 °

The measure of <D is 130 degree.

Angle sum property of triangle states that the sum of interior angles of a triangle is 180°.

Given:

<C= (x-4)

and, <D = 9x+ 4

and, <E = 2x+ 12

Now, In triangle CDE using Angle Sum Property

<D+ <E+ <F= 180

x - 4+ (9x+ 4) + 2x+ 12 = 180

12x + 12 = 180

12x = 168

The expected value of M does not change in a predictable manner when sample size increases; it can increase, decrease, or stay the same.

The expected value of M, or the mean of a sample, is determined by the values of the individual elements that comprise it. As such, when the sample size increases, the expected value of M could increase, decrease, or remain constant, depending on the particular values of the individual elements in the sample. This is because the expected value of M is the average of the individual elements and the contribution of each element to the average depends on its value and the number of elements in the sample. Therefore, the expected value of M does not change in a predictable manner when sample size increases. Depending on the individual elements in the sample, the expected value of M could be higher, lower, or constant.

As the firm develops a specific sort of sensor and ships them in boxes of four, each sensor weighed 10 grams at first.

In its most basic form, an equation is a mathematical statement that indicates that two mathematical expressions are equal. 3x + 5 = 14, for example, is an equation in which 3x + 5 and 14 are two expressions separated by a 'equal' sign. A mathematical phrase with two equal sides separated by an equal sign is called an equation. An example of an equation is 4 + 6 = 10.

Here,

Let's call the original weight of each sensor "w". The total weight of 4 sensors would be 4w.

With the new design, each sensor weighs 9 grams more, so each sensor weighs w + 9 grams. The total weight of 4 sensors is 76 grams, so we can write an equation:

4(w + 9) = 76

Expanding the left-hand side and solving for w, we have:

4w + 36 = 76

4w = 40

The temperature of the hot chocolate will decrease over time and after 4 minutes, it will be around 56 degrees Fahrenheit.

When you put something hot into a freezer, the temperature of the item will decrease over time until it reaches the temperature of the freezer. The rate of temperature decrease depends on the difference between the original temperature and the temperature of the freezer. In this case, the difference is 190 degrees Fahrenheit. The rate of temperature decrease should be roughly 1 degree Fahrenheit per second. After 4 minutes, the temperature of the hot chocolate should be around 56 degrees Fahrenheit. This is because, after 4 minutes, the hot chocolate would have lost around 190-56 = 134 degrees Fahrenheit of temperature.

The center of gravity of the combination of the two circles is at (x, y) = (0, 4/5).

The center of gravity, or the center of mass, of a two-dimensional object can be found by taking the weighted average of the x-coordinates and y-coordinates of the individual masses making up the object.

In this case, the two circles can be treated as point masses, with the mass of each circle being proportional to its area. The area of a circle with radius r is given by pi * r^2.

So, for circle c1 with radius 2, its mass is given by:

m1 = pi * 2^2 = 4 * pi

And for circle c2 with radius 1, its mass is given by:

m2 = pi * 1^2 = pi

The x-coordinate of the center of gravity is given by the weighted average of the x-coordinates of the two masses:

x = (m1 * 0 + m2 * 0) / (m1 + m2) = 0

Similarly, the y-coordinate of the center of gravity is given by the weighted average of the y-coordinates of the two masses:

y = (m1 * 0 + m2 * 4) / (m1 + m2) = 4 * (m2 / (m1 + m2)) = 4 * (pi / (4 * pi + pi)) = 4 * (pi / 5 * pi) = 4/5

So, the center of gravity of the combination of the two circles is at (x, y) = (0, 4/5).

Rounding to 2 decimal places, the shaded area is 234 cm².

What is the radius of circle?

The radius of a circle is the distance from the center of the circle to any point on the circumference of the circle. It is half of the diameter of the circle.

The diameter of the circle is 0.2 meters, which means the radius of the circle is 0.2 / 2 = 0.1 meters.

The height of the square is a fifth of the diameter of the circle, so the height of the square is 0.2 / 5 = 0.04 meters.

To find the shaded area in cm, we need to find the area of the circle and subtract the area of the square. The area of the circle is given by the formula πr², where r is the radius of the circle. The area of the square is simply the height multiplied by the width, which is equal to the diameter of the circle.

So, the area of the circle is π * 0.1² = 0.0314 square meters. The area of the square is 0.2 * 0.04 = 0.008 square meters. The shaded area is the difference between these two, or 0.0314 - 0.008 = 0.0234 square meters.

To convert the area to cm², we need to multiply by 10⁴. The shaded area in cm² is 0.0234 * 10⁴ = 234 cm².

Rounding to 2 decimal places, the shaded area is 234 cm^2.

So, the radius OM is perpendicular to line LN at point M.

Hence,

The value of ∠QML = 90°

2) To determine the degree measurement of angle PMN

∠QMN = ∠QMP + ∠PMN

By the angle addition postulate, we can calculate this measurement as follows:

∠QMN = 90°

∠QMP = 27°

Replace with and substitute the value of angle QML into the equation.
