If Peter wanted to buy only postcards, he could buy 2 postcards.

Given that,

Peter can afford to buy either 4 postcards and 9 stickers or 8 postcards and 6 stickers.

Both options leave him with no change.

Peter wants to buy only postcards.

Assume that the cost of a postcard is the same as the cost of a sticker.

In the first scenario,

Peter spends the same amount on postcards and stickers.

So, if he wanted to buy only postcards,

He could buy half the number of postcards he could buy in the first scenario.

Therefore, Peter would be able to buy 2 postcards if he wanted to buy only postcards.

The total volume of the tank is 300L.

The volume of a 3D figure is the space that it occupies.

Here, we are given that Yuki adds cleaning solution that is 7/900 of the tank's total volume.

Let the total volume of the tank be V

We know that the cleaning solution required to clean this tank is 2 1/3 L

Firstly, we need to convert this mixed fraction into an improper fraction, Thus, 2 1/3 = (2*3 + 1)/ 3

= 7/3 L

Thus, we can make the following equation,

(7/900)* V = 7/3

V = 7/3 (900/7)

V = 900/ 3

V = 300

Thus, the volume of the tank is 300L.

Just did it on Khan academy.

Mario viaja 48 segundos para encontrarse con Luis.

La distancia se define como la longitud de la trayectoria real recorrida por una partícula en movimiento. El desplazamiento se define como la distancia más corta entre la posición inicial y final de un cuerpo. La distancia recorrida por una partícula en una unidad de tiempo se conoce como velocidad.

La distancia entre Luis y Mario es de 240 metros.

La velocidad al caminar de Luis es de 3 m/s.

La velocidad al caminar de Mario es de 5 m/s.

La distancia se puede definir como el producto de la velocidad y el tiempo que tarda el objeto.

Por lo tanto,

Para que Mario alcance a Luis,

Distancia = Velocidad × Tiempo

240 = 5 × t

t = 240/5 = 48 sec.

Mario tiene que viajar durante 48 segundos para encontrarse con Luis.

The values are different on both sides, this shows that the equation has no solution.

Linear equations are equation that has a linear degree of 1. Given the expression below;

10x = 2.5x

You can see that the variable of "x" are on on both sides, hence we can cancel them out to have:

10x/x = 2.5x/x

10 = 2.5

From the result, you can see that the values are different on both sides, this shows that the equation has no solution.

The linear equation has only one solution, which is x = 0.

Here we have the linear equation:

10x = 2.5*x

Let's solve this to see how many solutions we have, if we subtract 2.5x in both sides we get:

10x - 2.5x = 0

7.5x = 0

The only solution of this linear equation is x = 0.

7.5*0 = 0

(d) the Present United States is not a good example of a command economy.

A command economy is a crucial component of a political system in the economy in which the degree of output that is permitted and the prices that may be paid for goods and services are set by a central governing body. Most industries are owned by the public.

The principal alternative to a command economy is a free market b where supply and demand determine prices and output.

A communist political system includes a command economy, whereas capitalist countries have a free market.

Cuba, North Korea, and the former Soviet Union all have command economies. Up until 1978, when it started to shift to a mixed economy that combines communist and capitalist features, China maintained a command economy. A socialist market economy has been used to characterize its existing setup.

The central government of a country must possess and manage the means of production in a command economy, commonly referred to as a planned economy.

There is no private ownership of land or capital, or it is very restricted. Prices are determined by central planners, who also manage production levels and restrict or forbid competition in the private sector. There is no private sector in a command economy because all companies are owned by or under the supervision of the central government.

Government officials establish national economic priorities in a command economy, such as when and how to promote economic growth, how to share resources, and how to disperse the produce. This frequently takes the shape of a long-term plan.

Hence, the United States today is not a very good example of a command economy.

Answer:

  852

Step-by-step explanation:

You want the next number in the pattern that starts with 5, 12, 33, 96, 285.

When looking for patterns in sequences, it is often useful to consider first differences and the relations between them.

  12 -5 = 7

  33 -12 = 21

  96 -33 = 63

  285 -96 = 189

We notice that these differences have a common ratio of 3. This suggests the next difference will be 189×3 = 567.

The next number in sequence is 285 +567 = 852.

__

Additional comment

When differences have a common ratio, an exponential sequence is indicated. These differences have a ratio of 3, but are not powers of 3, so the exponential term needs additional components to completely describe the sequence. We expect there are horizontal and vertical offsets involved.

Answer: 1L = 1000 mL

Step-by-step explanation:

1.     1 milligram (mg) is equal to 0.001 gram (gm), so 10mg = 0.01. The first choice is incorrect

2.    1 liter (L) = 1000 milliliter (mL) so the second choice is correct

3.    1 microgram (mcg) is equal to 0.001 milligram (mg), so the third                                                                 choice is incorrect.

4.    1 liter (L) = 1000 milliliter (mL), so the fourth choice is evidently                                        incorrect. (1000 L would be 1,000,000 mL)

Greetings from Brasil...

In a trigonometric function of Cosine, we have:

where

A = move the graph up or down

B = change the amplitude

M = change period

N = move the graph left or right without distorting it

According to the statement, we don't have A and N, so

F(X) = ± B.COS(MX)

According to the graph presented, we have:

B = amplitude = 2.5 = 5/2

period = π

detail that

Period = 2π/M

π = 2π/M ⇒ M = 2

As B = 5/2 and M = 2, then

(I used the cosine function, because in X = 0  Y will have a non-zero value, as we can see in the graph)

Answer: Why is the question blank

Also the answer is 5.2

Step-by-step explanation:

The coordinates of our position after moving up and down will be (0, -7)

We are given a coordinate plane and we are standing at the origin of the plane.

That is, our position is (0, 0).

Now, we move 2 units in the positive direction.

So, now our position will be:

(0, 2)

Then, we move downward a distance of 9 units.

So, our position will now become:

(0, 2 - 9)

(0, -7)

Therefore, the coordinates of our position after moving up and down will be (0, -7)

From the example that if a = 3 and b = 3 so the value of n = 6. It means that a ≤ n/2 and b ≤ n/2.

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that all integers a, b, and n, if n = a + b, then a ≤ n/2 or b ≤ n/2. Let the value of a = 3 and b = 3 now the value of n will be:-

n = a + b

n = 3 + 3 = 6

a = 3, n = 6 then a ≤ n/2.

b = 3, n = 6 then  b ≤ n/2.
