Step-by-step explanation:

Answer:

im pretty sure the answer is 7

Answer:

37 boxes

Step-by-step explanation:

At first, Dymin had some boxes. Let x be the starting number of boxes.

Then, she bought 7 more boxes. Let y be the new number of boxes that she had.

y = x + 7

Next, her little brother destroyed half of them. It means half of y. So, the number of boxes left is

Number of boxes = y/2

The number of the boxes left is 22 boxes. Then, we can use the equation above.

Number of boxes = 22

y/2 = 22

Substitute y = x + 7 into the equation.

(x + 7)/2 = 22

x + 7 = 44

x = 44 - 7

x = 37

Thus, Dymin has 37 boxes at first.

The definite integral of -f(u) from 3 to 4 is 4.

Since we know the definite integral of f(x) from 3 to 4 is -4, we can use the following formula to find the definite integral of 9f(u) from 3 to 4:
∫[3 to 4] 9f(u) du = 9 ∫[3 to 4] f(u) du

This is because we can factor the constant 9 outside of the integral, and we're left with the integral of f(u) from 3 to 4.

So, we can substitute -4 for the integral of f(x) from 3 to 4:
∫[3 to 4] 9f(u) du = 9(-4) = -36

Therefore, the definite integral of 9f(u) from 3 to 4 is -36.

Now, let's find the definite integral of -f(u) from 3 to 4. We can use a similar method:
∫[3 to 4] -f(u) du = -∫[3 to 4] f(u) du

This is because we can factor out the constant -1, which changes the sign of the integral. So, we can substitute -4 for the integral of f(x) from 3 to 4:
∫[3 to 4] -f(u) du = -(-4) = 4

Therefore, the definite integral of -f(u) from 3 to 4 is 4.

The independent variable in this study is the temperature of the water in each tank. The independent variable is the factor that is intentionally manipulated or changed by the researcher in order to observe its effect on the dependent variable. In this case, the researcher is testing the effects of habitat space on the size of fish populations, and they are manipulating the temperature of the water to see how it impacts the survival of the goldfish.

The researcher sets up four aquariums of the same size with six goldfish in each one. The independent variable, temperature, is kept different in each tank. This means that each tank is maintained at a different temperature throughout the experiment.

By manipulating the temperature in each tank, the researcher can observe how the different temperature conditions affect the survival of the goldfish. This allows them to determine whether the size of the fish populations is influenced by habitat space, as measured by the temperature of the water.

To summarize, in this study, the independent variable is the temperature of the water in each tank. The researcher is manipulating the temperature to observe its effect on the survival of the goldfish and determine the impact of habitat space on fish populations.

Answer:

Se obtuvo $ 448 de ganancia por la venta de donas.

Se obtuvo $ 280 de ganancia por la venta de bolillos.

Step-by-step explanation:

1) ¿Cuanta ganancia se obtuvo en la venta de donas?

La ganancia es el producto del porcentaje producido de donas, expresado como razón, el precio unitario de la dona y el total producido de panes. Es decir:

\(C = \frac{40\,donas}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{dona} \right)\)

\(C = 448\,USD\)

Se obtuvo $ 448 de ganancia por la venta de donas.

2) ¿Cuanta ganancia se obtuvo en la venta de bolillos?

La ganancia es el producto del porcentaje producido de bolillos, expresado como razón, el precio unitario del bolillo y el total producido de panes. Es decir:

\(C = \frac{25\,bolillos}{100\,panes}\times (140\,panes)\times \left(8\,\frac{USD}{bolillo}\right)\)

\(C = 280\,USD\)

In this exercise we have to use the knowledge of finance to calculate the profit.

1) $ 448 profit was made from donut sales.

2) A profit of $ 280 was obtained from the sale of cupcake.

1)The profit is the product of the percentage produced of donuts, expressed as a ratio, the unit price of the donut and the total produced of breads. That is to say:

\(C= (\frac{40}{100} )*(140)*(8)= 448 USD\)

$ 448 profit was made from donut sales.

2) The profit is the product of the percentage of cupcake produced, expressed as a ratio, the unit price of the cupcake and the total amount of bread produced. That is to say:

\(C= (\frac{25}{100}) *(140)*(8)= 280 USD\)

Answer:

Answer:x − x^{2} − 1.

Step-by-step explanation:

.

1.1) The volume of the cube is 27 cubic centimeters. 1.2)the density of the ice cube is approximately 0.917 grams per cubic centimeter (g/cm³).

1.3) the mass of the water cube is 27 grams. 1.4) the weight of the water and the ice would be the same under the same conditions. 1.5)In simpler terms, ice floats on water because it is lighter (less dense) than the water, allowing it to displace an amount of water equal to its weight and float on the surface.

1.1) The volume of the cube can be calculated using the equation: Volume = width x height x length. In this case, the cube measures 3 cm wide, 3 cm tall, and 3 cm long, so the volume is:

Volume = 3 cm x 3 cm x 3 cm = 27 cm³.

Therefore, the volume of the cube is 27 cubic centimeters.

1.2) Density is defined as mass divided by volume. The mass of the ice cube is given as 24.76 grams, and we already determined the volume to be 27 cm³. Therefore, the density of the ice cube is:

Density = Mass / Volume = 24.76 g / 27 cm³ ≈ 0.917 g/cm³.

Therefore, the density of the ice cube is approximately 0.917 grams per cubic centimeter (g/cm³).

1.3) The volume of the water cube is the same as the ice cube, which is 27 cm³. Given the density of liquid water as 1.00 g/cm³, we can calculate the mass of the water cube using the equation:

Mass = Density x Volume = 1.00 g/cm³ x 27 cm³ = 27 grams.

Therefore, the mass of the water cube is 27 grams.

1.4) The weight of an object depends on both its mass and the acceleration due to gravity. Since the volume of the water cube and the ice cube is the same (27 cm³), and the mass of the water cube (27 grams) is equal to the mass of the ice cube (24.76 grams), their weights would also be equal when measured in the same gravitational field.

Therefore, the weight of the water and the ice would be the same under the same conditions.

1.5) Ice floats on water because it is less dense than liquid water. The density of ice is lower than the density of water because the water molecules in the solid ice are arranged in a specific lattice structure with open spaces. This arrangement causes ice to have a lower density compared to liquid water, where the molecules are closer together.

When ice is placed in water, the denser water molecules exert an upward buoyant force on the less dense ice, causing it to float. The buoyant force is the result of the pressure difference between the top and bottom surfaces of the submerged object.

In simpler terms, ice floats on water because it is lighter (less dense) than the water, allowing it to displace an amount of water equal to its weight and float on the surface.

Step-by-step explanation:

Spontaneous recovery is the reappearance of the conditioned response when a rest period has taken place or when there's a period of lessened response.

In this case, since the researchers put the dog back in his cage for three hours after which the dog went through the conditioning process again after the three hours, then there'll be a spontaneous recovery.

A Increment value in a loop can be either a positive or a negative number.

Positive Increment: A positive increment is when the value of the loop increases on each iteration.

Negative Increment: A negative increment is when the value of the loop decreases on each iteration.

In a step value, the counter variable is either an increment or a decrement every time the loop is executed. If the counter variable is decreased, it can go as low as a negative number, whereas with an increment, the counter variable can be either negative or positive with each loop executed increased.

Thus, the relationship between the students and the tickets sold is not a function A function is a relation in which one input can have only one output.

Let the students be = x

Let the number of tickets sold by the student be = y

Thus, from the table, it can be inferred -
