Step-by-step explanation:

The diameter of Earth in kilometers is approximately 12,682 km, making option D the correct answer.

To convert the diameter of Earth from miles to kilometers, we can multiply the given diameter in miles by the conversion factor of 1.6 kilometers per mile.

Given that Earth's diameter is 7,926 miles, we can calculate its diameter in kilometers as follows:

Diameter in kilometers = Diameter in miles × Conversion factor

Diameter in kilometers = 7,926 miles × 1.6 kilometers/mile

Diameter in kilometers = 12,681.6 kilometers

Rounding this value to the nearest whole number, we get 12,682 kilometers.

Therefore, the correct answer is option D: 12,682 km.

Option A: 49,553 km is not the correct answer. It is not consistent with the given diameter of Earth.

Option B: 120,586 km is also not the correct answer. It is not consistent with the given diameter of Earth.

Option C: 1,392,650 km is significantly larger than the actual diameter of Earth and is not a plausible value.

In conclusion, the diameter of Earth in kilometers is approximately 12,682 km, making option D the correct answer.

The mean is the same as the average.

He invested $18,000 in first account and $14,000 in second account

The term "percentage" refers to a quantity or ratio that is stated as a fraction of 100. Although the acronyms "pct.," "pct." and occasionally "pc" are also used, the percent sign is most frequently used to signify it. A % is an irrational (pure) number that has no dimensions.

Given that he is fasting $32,000 into two accounts and paid 2% and 6% simple interest respectively ,after one year the total interest was 1200 .

x + y = 32,000

0.02x + 0.06y = 1200

0.02x + 0.06(32,000 - x) = 1200

0.02x + 1920 - 0.06x = 1200

0 = 1200 + 0.06x - 1920 - 0.02x

0 = 0.04x - 720

720 = 0.04x

\(\frac{720}{0.04}\) = x

18,000 = x

y = 32000 - 18000

We need to calculate the power of the heater to warm up the given air to a specified temperature and relative humidity.

The process of heating air involves three essential steps. These are preheating, humidifying, and heating.

Firstly, we need to preheat the air to increase the temperature of the air. After that, the air is humidified to the desired relative humidity, and finally, the air is heated to the required temperature.
The air we want to warm up has the following parameters:
Volume flow rate of air = 5000 cubic meters per hour
Initial temperature of air = 5 deg C
Relative humidity = 40%
Final temperature of air = 30 deg C
Step 1: Preheating the air
The specific heat of air is approximately 1 kJ/kgK. To preheat the air, we need to calculate the amount of heat required to raise the temperature of the air from 5 deg C to 30 deg C.
The density of air is approximately 1.2 kg/cubic meter, and hence, the mass of air flowing per hour is given by:
Mass of air = Volume flow rate × Density = 5000 × 1.2 = 6000 kg/hour
The amount of heat required to raise the temperature of the air from 5 deg C to 30 deg C is given by:
Q = Mass × Specific heat × Temperature rise
 = 6000 × 1 × (30 - 5)
 = 150000 kJ/hour
Step 2: Humidifying the air
The air has a relative humidity of 40%, and we want to increase it to the desired relative humidity. We can use a steam humidifier to add water vapor to the air to increase its relative humidity. The amount of heat required to humidify the air is given by:
Q = Mass of water vapor × Latent heat of vaporization
The mass of water vapor required to increase the relative humidity from 40% to the desired value can be calculated using psychrometric charts. For the given parameters, the mass of water vapor required is approximately 0.012 kg/kg of dry air.
The latent heat of vaporization of water is approximately 2260 kJ/kg. Hence, the amount of heat required to humidify the air is given by:
Q = 6000 × 0.012 × 2260 = 162720 kJ/hour
Step 3: Heating the air

Finally, we need to heat the air from 5 deg C and relative humidity of 40% to 30 deg C. The amount of heat required to raise the temperature of the air is given by:
Q = Mass × Specific heat × Temperature rise
 = 6000 × 1 × (30 - 5)
 = 150000 kJ/hour
The total heat required to warm up the air is the sum of the heat required in the three steps, i.e.,
Total Q = 150000 + 162720 + 150000
         = 462720 kJ/hour
The power of the heater required to supply this amount of heat can be calculated using the following formula:
Power = Total Q / (Efficiency × Time)
     = 462720 / (0.8 × 3600)
     ≈ 160.77 kW

The power of the heater required to warm up five thousand cubic meter per hours of air + 5 deg C and relative humidity 40% to temperature + 30 deg C is approximately 160.77 kW.

Answer:

The correct option is D.

Step-by-step explanation:

A histogram is a bar chart wherein the horizontal scale signifies class interval (or classes of data values) and the vertical scale signifies frequencies or percentages. The altitudes of the columns relate to the frequency values, and the columns are drawn together without breaks.

The histogram has the following properties:

• Shows the shape of distribution

• Shows the location of center

• Shows the spread of data

• Helps in identifying outliers

Since the sample collected is so small, the true nature of the distribution cannot be seen with a histogram.

Thus, the correct option is D.

Let's use the distributive property to undo the parentheses. We multiply the number next to the parentheses by each number inside of the parentheses.

-7+3(-4e-3)

-7-12e-9

We combine like terms.

-16-12e

This means that Answer B is incorrect. Answer A could still be correct though as it could have equal value to -16-12e.

-4(3e+4)

We use distributive property.

-12e-16

We see that these have the same value, so the correct answer is A.

The probability will be 0.037 or 3.7% when it is rounded to the nearest tenth.

To calculate the probability of hitting the clown's mouth, we need to compare the area of the clown's mouth to the total area of the rectangular wood piece.

The area of the clown's mouth can be found using the formula for the area of a circle: A = π * (r^2), where r is the radius. In this case, the diameter is given as 3 inches, so the radius is 1.5 inches.

Plugging the values into the formula, we get A = π * (1.5^2) = 7.065 square inches. The total area of the rectangular wood piece is 16 inches * 12 inches = 192 square inches.

Therefore, the probability of hitting the clown's mouth is 7.065 / 192 ≈ 0.0367, which rounds to 0.037 or 3.7% when expressed as a percentage rounded to the nearest tenth.

Answer: 3

Step-by-step explanation:

The missing number in the simplified ratio ?/4 is 3.

Here, we have to find the missing number in the simplified ratio ?/4, we need to determine the ratio of girls to boys in Mr. Stevenson's class.

Given that there are 6 girls and 8 boys in the class, the ratio of girls to boys can be expressed as:

Number of girls : Number of boys = 6 : 8

To simplify the ratio, we can divide both the number of girls and the number of boys by their greatest common divisor (GCD).

In this case, the GCD of 6 and 8 is 2.

Dividing both 6 and 8 by 2, we get:

Number of girls : Number of boys = 6/2 : 8/2 = 3 : 4

So, the simplified ratio of girls to boys is 3/4.

Therefore, the missing number in the simplified ratio ?/4 is 3.

To use the chain rule, we first identify the outer function and the inner function. We then take the derivative of the outer function, leaving the inner function untouched. Finally, we multiply the result by the derivative of the inner function.In summary, the chain rule is an important tool in calculus used to find the derivative of composite functions.

However, I can give an explanation of the chain rule. The chain rule is a rule in calculus used to find the derivative of a composite function. A composite function is a function that is made up of two or more functions, where the output of one function is the input of another.  To use the chain rule, we first identify the outer function and the inner function. We then take the derivative of the outer function, leaving the inner function untouched. Finally, we multiply the result by the derivative of the inner function. For example, let's say we have the function f(x) = sin(3x). The outer function is sin(x) and the inner function is 3x. Using the chain rule, we take the derivative of the outer function, which is cos(3x), and leave the inner function untouched, which is 3. We then multiply the two together to get the derivative of f(x), which is f'(x) = 3cos(3x).
