Step-by-step explanation:

We Know

1 serving of stir fry uses 2/3 cup of rice.

How many cups are in 13 servings?

We Take

2/3 x 13 = 26/3 cup of rice

So, there are 26/3 cups of rice are in 13 servings.

Answer:

26/3 (8 2/3) cups

Step-by-step explanation:

If one serving of stir fry uses 2/3 cups of rice,

1:2/3

If there are 13 servings,

13: 2/3 * 13

13: 26/3

So 26/3 cups of rice

With respect to the average cost curves, the marginal cost curve: intersects both average total cost and average variable cost at their minimum points that is option B.

The fixed cost per unit of production is the average fixed cost (AFC). AFC will reduce consistently as output grows since total fixed costs stay constant. The variable cost per unit of production is known as the average variable cost (AVC). AVC generally declines until it reaches a minimum and then increases due to the growing and then lowering marginal returns to the variable input. The average total cost curve's (ATC) behaviour is determined by the behaviour of the AFC and AVC.

Considering the provided formula and information, we are going to calculate the requested percent of college freshmen in 2010, so we obtain the following:

So since x corresponds to the number of years after 1980, in this case we will replace x with 30, since it is 30 years after 1980, we have:

p=4x/5+25

Replacing:

p=4(30)/5+25

p=120/5+25

p=24+25

p=49

So, as we can see, the model assumes that in 2010 the percentage was 49%, and the real one is 47%. It means that the model overestimates the real value by 2%.

(x, y) → (–x, –y)

Step-by-step explanation:

Given

\(R_0, 180^{\circ}\)

Required

Another way to write the above transformation

The above transformation means 180 degrees clockwise rotation.

When a coordinate point (x,y) undergoes this type of transformation, the new coordinate point becomes (-x,-y).

Hence, another way to write \(R_0, 180^{\circ}\) is (x, y) → (–x, –y)

The rate at which the water level is rising when the water level is 6 cm is approximately 2.67 cm/s. if an inverted pyramid is filled with water at a constant rate of 55 cubic centimeters per second, the top of pyramid is in square shape with length of 8 cm and height of 14 cm.

Let's call this rate "r".

Volume of pyramid = (1/3) * base area * height

Since the pyramid has a square base, the base area is given by

Base area = (side length)^2

Substituting the given values

Base area = (8 cm)^2 = 64 cm^2

Height = 14 cm

V = (1/3) * 64 cm^2 * 14 cm = 298.67 cm^3

We know that the water is being added to the pyramid at a constant rate of 55 cm^3/s. Therefore, the rate at which the volume is increasing is

dV/dt = 55 cm^3/s

We also know that the volume of water in the pyramid at any given time is given by

V_water = (1/3) * base area * h_water

where h_water is the height of the water at that time.

To find the rate at which the water level is rising (r), we need to find dh_water/dt. We can do this by taking the derivative of both sides of the equation for V_water with respect to time

dV_water/dt = (1/3) * base area * dh_water/dt

Substituting the known values

dV_water/dt = (1/3) * (8 cm)^2 * dh_water/dt

dV_water/dt = (64/3) cm^2 * dh_water/dt

dh_water/dt = 3 * dV_water/dt / 64

dh_water/dt = 3 * 55 cm^3/s / 64 = 2.67 cm/s

(a) The volume of the prism is 144 cubic units. (b) Area of shaded base is 16 square units. Volume of prism is 144 cubic units. Both methods give the same result for the volume of the prism.

A rectangular prism is a three-dimensional geometric figure that consists of six rectangular faces that meet at right angles. It is also known as a rectangular cuboid or a rectangular parallelepiped. The rectangular prism is a special case of a parallelepiped, where all six faces are rectangles.

The rectangular prism has three pairs of parallel faces, each pair being congruent to each other. The length, width, and height of a rectangular prism are its three dimensions, and they are usually denoted as l, w, and h respectively.

(a) The expression to find the volume of the prism is:

Volume of prism = length x width x height

Substituting the given values, we get:

Volume of prism = 8 x 2 x 9 = 144 cubic units

(b) The shaded base of the prism is a rectangle with dimensions 8 by 2. Therefore, the area of the shaded base is:

Area of shaded base = length x width = 8 x 2 = 16 square units

We can also find the volume of the prism by multiplying the area of the shaded base by the height of the prism. The expression to find the volume of the prism using the area of the shaded base is:

Volume of prism = area of shaded base x height

Substituting the values, we get:

Volume of prism = 16 x 9 = 144 cubic units

As expected, both methods give the same result for the volume of the prism.

True/False question cannot be answered with a "main answer". However, the archaeologists do believe that the cities of Sodom and Gomorrah were near the Dead Sea.

The location of Sodom and Gomorrah is a subject of debate among archaeologists and scholars. Some believe that they were located near the Dead Sea, while others propose different locations. However, the prevailing theory is that they were situated near the Dead Sea, which is a salt lake bordered by Jordan to the east and Israel and Palestine to the west.

The true/false question you have posed cannot be answered with a long answer as it is a binary question. However, if you want to know more about the archaeology and history of Sodom and Gomorrah, there is a wealth of information available online and in scholarly articles and books. The story of Sodom and Gomorrah is a biblical tale that recounts the destruction of two cities by God due to their wickedness. The story appears in both the Book of Genesis in the Hebrew Bible and in the Quran. Archaeological evidence suggests that there were settlements in the area of the Dead Sea around the time the story of Sodom and Gomorrah is said to have occurred, but there is no conclusive proof that these were the cities referred to in the Bible. Some scholars argue that the story is a myth, while others believe that there is a historical basis for it. Regardless of the veracity of the tale, the story of Sodom and Gomorrah has captured the imagination of people for centuries and continues to be a subject of scholarly inquiry.

Answer: The area is 6.5

Answer:

A

Step-by-step explanation:

Shape A is a dilation with scale factor 2 of shape S. Therefore, it is similar.

Similar shapes share angles, and the scale factor between their dimensions is a constant proportion. We can verify this on shape A by looking at the shape's height and width:

             shape S          shape A

height:       2                      4

width:         3                      6

We can see that shape A's dimensions are double those of shape S.

             shape S          shape A

height:       2       × 2 =       4

width:         3       × 2 =       6

—

When we compare shape S with another shape — say, for example, shape C, we can see that the side lengths are not dilated proportionately; the height is dilated by 2, but the width is dilated by 5/3. Therefore, the shape S and shape C are not similar.

             shape S          shape C

height:       2       × 2 =       4

width:         3    × 5/3 =       5

The given natural deduction proof system is valid. The premises state that for all values of a, b, and c, if Y(a, b) and Y(b, c) are true, then Y(a, c) is also true. It also states that for all values of a and b, if Y(a, b) is true, then Y(b, a) is also true. Lastly, it states that for all values of a, there exists a value of b such that Y(a, b) is true. The conclusion is that for all values of a, Y(a, a) is true.

To prove the validity of the natural deduction proof system, we need to show that the conclusion is logically derived from the given premises.

1. Let's assume an arbitrary value for a and show that Y(a, a) holds.

2. From the third premise, we know that there exists a value of b such that Y(a, b) is true. Let's call this value of b as b1.

3. Applying the second premise to Y(a, b1), we get Y(b1, a).

4. Using the first premise, we have Y(b1, a) and Y(a, a), which implies Y(b1, a) and Y(a, b1), and consequently Y(b1, b1).

5. Now, we can use the first premise again with Y(b1, b1) and Y(b1, a) to obtain Y(a, a).

Since we have shown that for any arbitrary value of a, Y(a, a) holds, we can conclude that the given natural deduction proof system is valid. It establishes that for all values of a, Y(a, a) is true.

The graph of N(t) = 75t + 120 is a straight line with a positive slope of 75. It intersects the y-axis at (0, 120) and has a y-intercept of -8/5. As t approaches infinity, N(t) increases without bound, indicating a positive relationship between the number of days of training and the average number of components assembled per day.

To sketch the graph of N(t) = 75t + 120, we can plot points on the coordinate plane by substituting different values of t into the equation.

For example, when t = 0, N(0) = 75(0) + 120 = 120. So, we have the point (0, 120).

When t = 1, N(1) = 75(1) + 120 = 195. So, we have the point (1, 195).

We can continue to calculate more points using different values of t.

The intercept is when N(t) = 0:

0 = 75t + 120

-120 = 75t

t = -120/75

t = -8/5

So, we have the intercept (0, -8/5).

To find the asymptote, we need to check what happens to N(t) as t approaches infinity. As t becomes larger and larger, the constant term 120 becomes less significant compared to the term 75t. Therefore, as t approaches infinity, N(t) approaches infinity as well.

In practical terms, this means that as the number of days of training (t) increases, the average number of components assembled (N) per day also increases. However, it is important to note that this is based on past records and the actual performance of new employees may vary. The equation provides an average trend and does not account for individual variations or other factors that may affect productivity.

Step-by-step explanation:

a)

any prime number has only 2 (1 and the number itself).

almost every even number has 1, 2, a factor of 2 and the number itself. so that did not work either.

following that line of thought, the only possible solutions are square numbers of prime numbers :

4, 9, 25, 49

they have only 1, its square root and the number itself as factors.

b)

in the same line of thinking it must be powers of 4 of prime numbers :

2⁴ = 16

with the factors 1, 2, 4, 8, 16

3⁴ = 81

with the factors 1, 3, 9, 27, 81

c)

Step-by-step explanation:

so first you are given that 6 is 128 degrees and since angle 2 is the corresponding angles of angle 6 that means they are equal to each other. So since angle m1 and m2 are linear pairs you just need to substract 180-128 and then you'll get the answer for m1 which is 52. since m1 and m3 are vertical angles they are equal so they both have a angle measure of 52
