Determine whether the statement is true or false. If it is false, rewrite it as a true statement. Data at the ratio level cannot be put in order.
Answer:
False
Step-by-step explanation:
The statement is a false statement. We're asked to rewrite it as a true statement if it were false. Since it's false, we then try to rewrite it as a true statement, in so doing we are going to have it like this
"Data at the ratio level can be placed in a meaningful order."
Now we've successfully written it as a true statement

if 12 1/2% of a sum of money is $60 what is the total sum of money?
Answer: $480
Step-by-step explanation:
\(12 \frac{1}{2} \%\) expressed as a decimal is 0.125.
Let the total sum of money be \(x\). Then, \(0.125x=60 \implies x=480\).
Solve the compound inequality.
4x-5<-2 or x+1>3
The solution of the compound inequality is x < 3/4 or x >2.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
A compound inequality:
4x - 5 < -2 or x + 1 > 3.
Solving inequality,
4x < -2 + 5 or x > 2
4x < 3 or x > 2.
x < 3/4 or x >2.
Therefore, the solution is x < 3/4 or x >2.

35. The equation v=20Vt + 273 relates the speed v, in m/s, to the air
temperature t in Celsius degrees.
a. Find the temperature when the speed of sound is 340 m/s.
b. Find the temperature when the speed of sound is 320 m/s.
a. The temperature is about 3.35 degrees Celsius at 340 m/s, the speed of sound.
b. The temperature is about 2.35 degrees Celsius at 320 m/s, or the speed of sound.
Describe Speed?Speed is a scalar physical quantity that quantifies the rate of motion of an object. It is described as the distance that an object covers in a specific period of time. Meters per second (m/s) is the SI unit for measuring speed.
The speed formula is as follows:
Speed = distance / time
Depending on the purpose, speed can also be stated in different units, such as kilometres per hour (km/h), miles per hour (mph), or feet per second (ft/s).
The concept of speed, which is used to describe how objects move, is important to physics. It plays a significant role in a variety of fields of science, engineering, and technology, including sports, aircraft, and transportation. For the purpose of analysing and forecasting the behaviour of physical systems, it is essential to comprehend the idea of speed.
a. We can change v = 340 into the equation and solve for t to determine the temperature when the speed of sound is 340 m/s:
v = 20Vt + 273
340 = 20Vt + 273
67 = 20Vt
t = 67/20
Therefore, the temperature is about 3.35 degrees Celsius when the sound travels at 340 m/s.
b. We may once more enter v = 320 into the equation and solve for t to determine the temperature when the speed of sound is 320 m/s:
v = 20Vt + 273
320 = 20Vt + 273
47 = 20Vt
t = 47/20
As a result, the temperature is roughly 2.35 degrees Celsius at 320 m/s, the speed of sound.

Hi can any one teach me this constant difference
The constant differences between the consecutive terms are 2 (a); 2 (b), -3 (c), 7 (d), 1(e), and 6(f).
How do you find the constant difference in a sequence of numbers?In math, the constant difference can be defined as the number that defines the pattern of a sequence of numbers. This means that number that should be added or subtracted to continue with the sequence.
Due to this, to determine the constant difference it is important to observe the pattern and find out the number that should be added. For example, if the sequence is 2, 4, 6, 8, there is a difference of 2 between each of the numbers and this is the constant difference.

ASAP, PLSSS!!!! What is the range of the given function?
Answer:
[6, 8).
Step-by-step explanation:
When we are looking for the range of a function by just looking at the graph, we have to define from what point to what point the graph move vertically. On the other hand, if we were looking for the domain, we would state from where to where the graph moves horizontally.
In this case we have to analyze the graph vertically, since we are looking for the range of the function. Therefore, if we take a look at the line we can notice that it goes from y=6 to y=8. Therefore the range should be from 6 to 8.
Now, this result must be expressed in interval notation, meaning that we have to state whether the values of each end are contained or not by the function. The graph already tells us about it., because it marks it with the closed or open dots. In the case of the number 6, we have a closed dot, means that the function contains the number 6. For the other end we have an open dot, means that the function doesn't contain the number 8.
Applying internal notation, the range of this function is:

Un bloque de vidrio flint tiene un espesor de 4 cm, ¿qué espesor aparenta tener cuando se le ve desde arriba?
Answer: El índice de refracción del vidrio flint es mayor que el del aire. Cuando la luz pasa de un medio con un índice de refracción menor (como el aire) a un medio con un índice de refracción mayor (como el vidrio), experimenta un cambio de dirección. Este fenómeno se conoce como refracción.
Cuando observamos el bloque de vidrio flint desde arriba, la luz que proviene del bloque sufre refracción al pasar del vidrio al aire. Debido a la refracción, los rayos de luz se desvían y parecen venir de una posición más alta dentro del vidrio de lo que realmente están. Esto crea una ilusión óptica que hace que el espesor aparente del bloque de vidrio se vea más delgado de lo que realmente es.
La cantidad exacta de adelgazamiento aparente depende del ángulo de incidencia de la luz y de los índices de refracción del vidrio y el aire. Sin más información, no es posible determinar el espesor aparente específico del bloque de vidrio flint cuando se ve desde arriba.

In a bag full of candy, for every 8 pieces, 5 of them are gum. There are 20 pieces of gum. We want to find the total number of pieces of candy, c.
Answer:
32
Step-by-step explanation:
Since there are 20 total pieces of gum, we divide 20 by 5 to figure out how many groups of 8 pieces of candy there are (For every 8, 5 are gum). This gives us 4 groups of 8. Because for every 8 pieces, 5 are gum, we subtract 5 from 8 and get three. Multiply 3 by 4 (the number of groups), and we get 12 other pieces of candy. Add to 20, and we get 32. To check, divide 32 by the number of groups (4) and we get 8, which is how many pieces of candy are in each group.

The wheel on a scooter completes 124 revolutions and travels 22.4 meters. What is the diameter of the wheel in mm? Use 3.14 for pi and round to the nearest whole millimeter.
If wheel on a scooter completes 124 revolutions and travels 22.4 meters then diameter of the wheel is 57 mm
Each revolution of the wheel covers a distance equal to the circumference of the wheel.
The diameter of the wheel "d".
The distance covered in 124 revolutions is:
distance = 124 x circumference
= 124 x pi x d
= 124 x 3.14 x d
We know that this distance is equal to 22.4 meters, so we can set up an equation:
124 x 3.14 x d = 22.4
Simplifying and solving for d:
d = 22.4 / (124 x 3.14)
d = 0.057 meters
As we know that 1 meter is equal to thousand millimeters so multiply by 1000 to get in millimeters
d = 57 millimeters
Therefore, the diameter of the wheel is approximately 57 mm.

Find the product and simplify completely. 1 5/8 2 /3/5 MH Enter the number that goes in the green box. Enter
The Product of 1 5/8, 2, and 3/5 is equal to 39/20, which is simplified completely. The answer is 39/20.
To find the product and simplify completely, you need to perform multiplication and simplify the resulting fraction. Here, we are multiplying the following fractions and mixed numbers:1, 5/8, 2, and 3/5.The first step is to convert the mixed numbers into improper fractions.
We do that by multiplying the whole number by the denominator, and then adding the numerator.For 1 5/8, we get:$$1 \frac{5}{8} = \frac{8}{8} \times 1 + \frac{5}{8} = \frac{13}{8}$$For 2, we get:$$2 = \frac{2}{1} = 2 \times \frac{1}{1} = \frac{2}{1}$$For 3/5, we leave it as is since it's already a fraction.
Now that we have all the numbers as fractions, we can multiply them:$$\frac{13}{8} \times \frac{2}{1} \times \frac{3}{5} = \frac{13 \times 2 \times 3}{8 \times 1 \times 5} = \frac{78}{40}$$
To simplify the fraction, we can divide both the numerator and denominator by their greatest common factor, which is 2:$$\frac{78}{40} = \frac{2 \times 39}{2 \times 20} = \frac{39}{20}$$
Therefore, the product of 1 5/8, 2, and 3/5 is equal to 39/20, which is simplified completely. The answer is 39/20.
