The only option in which B can be the limiting reagent is A/B = 1.

The molecular equation for this hypothetical reaction is 3A + 3B → 3C + 3D. To determine which reactant is the limiting reagent, we must calculate the mole ratios of the reactants. In this case, we need to compare the ratio of A to B.

If we assume that the equation is balanced, then this means that there are an equal number of moles of A and B in the reaction. Therefore, the mole ratio of A to B is 1:1 (A/B = 1).

The other given options are 2A/7B, A/4B and A/5B. All of these ratios are greater than 1, meaning that B is in excess and will not be the limiting reagent. Therefore, the only option in which B can be the limiting reagent is A/B = 1.

The translation from figure 1 to figure 2 is 4 units to the left and one unit up.

Here we have two figures, the blue one is figure 1 and the orange one is figure 2.

Clearly we have a translation here, to identify the translation just analyze one of the vertices.

The top vertex at the blue figure is (2, 1)

The top vertex at the orange figure is (-2, 2)

The translation is given by:

Answer:

Step-by-step explanation:

answer is a

a) Y can be found using the midpoint formula, which states that the midpoint of a line segment has coordinates equal to the average of the coordinates of its endpoints. In this case, the coordinates of Y are equal to the average of the coordinates of X and M.

The formula for finding the midpoint of two points is:

Midpoint = ( (x1 + x2) / 2, (y1 + y2) / 2 )

So, the midpoint of X and Y is ( ( -4 + 4 ) / 2, ( 2 + 3 ) / 2 ) = (0, 2.5)

b) In the same way, the midpoint of X and Y is ( ( -1 + 1 ) / 2, ( -3 + -3 ) / 2 ) = (0, -3)

c) The midpoint of X and Y is ( ( 6 + 2 ) / 2, ( -3 + 1 ) / 2 ) = (4, -1)

The probability of the spinner not stopping at a white section 0.82.

The probability of the spinner not stopping at a white section is 1 minus the probability of the spinner stopping at a white section.

Since there are 2 white sections out of 11 total sections, the probability of stopping at a white section

The sum of the interior angles of a triangle is always 180°, using that we will see that x = 80°

The first thing you can notice is that we have a triangle with two equal sides, that means that the two bottom angles have the same measure.

Also, remember that the sum of the interior angles of any triangle is always equal to 180°, then we can write the equation:

50° + 50° + x = 180°

Solving that for x we will get:

x = 180° - 50° - 50° = 80°

The series 16+24+36+54+... diverges.

Divergent series are those that contain an infinite series that never converges and an infinite sequence of partial sums with no finite limit. In contrast, a series is considered to be convergent when its limits converge to its finite range of values. A limit that is finite in nature and exists for the partial sum of the series is crucial since only at that point will the series converge.

The given series in question 16 + 24 + 36 + 54 + deviates from the series. 16n, where n is the number of terms, can be used to denote the series' overall term. The total of the terms in the series also increases as n increases since 16n grows along with n, too. This indicates that the series diverges since it does not reach a particular finite value.

Step-by-step explanation:

X is tha same as the samll angle next to 77°

77+ x = 90    shows x = 13 degrees

Answer:

x=13 degrees

Step-by-step explanation:

by vertical angles, angle FGD = angle CGE = x

by supplementary angles, angle AGD = 90 degrees because angle AGC = 90 degrees

Because you know that AGF = 77 degrees, you can determine that

FGD = AGD-AGF

FGD = 90-77

FGD = 13

because of vertical angles, x = 13 degrees

The required surface area of a rectangular container is 588cm² using a volume of 1,372 cm³.

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In comparison to the definition of arc length for one-dimensional curves or the definition of surface area for polyhedra (i.e., objects with flat polygonal faces), where the surface area is equal to the sum of the areas of its faces, the mathematical definition of surface area in the presence of curved surfaces is significantly more complex.

The surface area of smooth surfaces, such as spheres, is determined using their representation as parametric surfaces.

Partial derivatives and double integration are used in this definition of surface area, which is based on infinitesimal calculus techniques.

So, we have the volume:

1,372 cm³

Then, h = 1372/s².

Now, calculate as follows:

4 s 1372/s^2 + s^2 = area

5488/s + s^2 = area

s^2 + 5488 (s^-1) = area    

2s - 5488 s^-2 = 0

5488 s^-2 = 2s

5488 = 2 s^3

2744 = s^3    

s =  14        

s * h * s = 1372    

Then, we will have: h = 7

Surface area = 14*14+4*7*14 = 196+4*7*14 = 588 cm²

Therefore, the required surface area of a rectangular container is 588cm² using a volume of 1,372 cm³.

Answer: 12$

Step-by-step explanation: To find the revenue produced for 45 units, we need to find the equation that represents the relationship between the number of units sold (u) and the revenue produced (r). Based on the information given in the table, we can see that the revenue increases as the number of units sold increases. So, we can assume that there is a direct proportion between the number of units sold and the revenue produced. Therefore, we can use the equation: r = ku, where k is the constant of proportionality.

We can use any two of the given pairs (u, r) to find k. For example, using (30, 8), we have:

8 = k * 30

k = 8 / 30 = 4/15

So, the equation representing the relationship between the number of units sold and the revenue produced is: r = 4/15 * u. To find the revenue produced for 45 units, we can plug in u = 45 into the equation:

r = 4/15 * 45 = 12.

Therefore, the revenue produced for 45 units is $12.

The price of each shirt is $7.5.

The price of each pant is $18.5.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 7 is an equation.

We have,

Cost of shirts = x

Cost of pants = y

Lisa buys her children four shirts and three pairs of pants for $85.50.

She returns the next day and buys three shirts and five pairs of pants for $115.00.

This means,

We can make two equations.

4x + 3y = 85.50

3x + 5y = 115

Now,

4x + 3y = 85.50

4x = 85.50 - 3y

x = (85.50 - 3y)/4

Substituting in 3x + 5y = 115.

3 (85.50 - 3y)/4 + 5y = 115

256.5 - 9y + 20y = 460

11y = 460 - 256.6

11y = 203.4

y = 18.5

And,

x = (85.50 - 3y)/4

x = (85.50 - 55.5)/4

x = 30/4

x = 7.5

Thus,

The cost of the shirt is $7.5.

The cost of the pant is $18.5.

Step-by-step explanation:

There are 150 different types of this shirt made.

There are 25 different colors, two different versions (male and female), and three different sizes for each. To calculate the total number of different types of shirt, we can use the formula: (25 colors) x (2 versions) x (3 sizes) = 150. Therefore, there are 150 different types of this shirt made.

To further illustrate, each color is available in both male and female versions, and each version has three sizes (small, medium, and large). As a result, 25 colors x 2 versions x 3 sizes = 150 different types of shirts. So, if you wanted a yellow shirt in size medium, there would be a total of 150 different types of this shirt to choose from. There are 150 different types of this shirt made.

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 3 = 7 is an equation.

We have,

y = x³ - 6x² - 15x - 7

Differentiating w.r.t x.

[ d[tex]x^n[/tex]/dx = n[tex]x^{n - 1}[/tex] ]

[ dc/dx = 0 ]

dy/dx = dx³/dx - 6dx²/dx - 15dx/dx - d7/dx

dy/dx = 3[tex]x^{3 - 1}[/tex]dx/dx - 6 x 2[tex]x^{2-1}[/tex]dx/dx - 15 - 0

dy/dx = 3x² - 12x - 15

Now,

dy/dx = 0

3x² - 12x - 15 = 0

3(x² - 4x - 5) = 0

x² - 4x - 5 = 0

x² - (5 - 1)x - 5 = 0

x² - 5x + x - 5 = 0

x(x - 5) + 1(x - 5) = 0

(x - 5) (x + 1) = 0

x - 5 = 0

x = 5 _____(1)

x + 1 = 0

x = -1 _____(2)

Now,

For x = 2,

dy/dx = 3x² - 12x - 15

dy/dx = 3 x 4 + 24 - 15

dy/dx = 12 - 24 - 15

dy/dx = 12 - 39

dy/dx = -27 _____(3)

For x = 2/3,

dy/dx = 3x² - 12x - 15

dy/dx = 3 x 4/9 + 24 x 2/3 - 15

dy/dx = 4/3 + 16 - 15

dy/dx = 4/3 + 1

dy/dx = 7/3 _____(4)

From (1), (2), (3), and (4)

dy/dx = 0 when x = - 2 and x = 2/3 is not possible.
