a 21.8 g sample of osmium would occupy a volume of approximately 0.9646 cm³.

To calculate the volume occupied by a sample of osmium, we can use the formula:

Volume = Mass / Density

Given:

Mass = 21.8 g

Density = 22.6 g/cm³

Substituting these values into the formula:

Volume = 21.8 g / 22.6 g/cm³

Simplifying:

Volume = 0.9646 cm³

what is volume?

Volume is a measure of the amount of space occupied by a three-dimensional object or substance. It quantifies the extent or capacity of an object or substance in terms of how much space it occupies.

In mathematical terms, volume is typically measured in cubic units (such as cubic meters, cubic centimeters, or cubic inches). It is calculated by multiplying together the three dimensions of the object (length, width, and height) or by using specific formulas depending on the shape of the object.

For example, the volume of a rectangular box can be calculated by multiplying its length, width, and height. The volume of a cylinder can be calculated using the formula πr²h, where r is the radius of the base and h is the height.

Volume is an essential measurement in various fields such as physics, engineering, chemistry, and everyday life. It helps determine capacities, quantities, displacements, and the amount of space occupied by objects or substances.

The maximum burn rate ∣ΔM/Δt∣ that the engine could reach before the ship's acceleration exceeded 5 g and its human occupants began to lose consciousness is approximately 51.0 kg/s.

Acceleration is directly proportional to the force acting on an object. In simple terms, if the force on an object is greater, then it will undergo more acceleration. However, there are limitations to the acceleration that can be tolerated by the human body. At about 5 g (49.0 m/s2) for more than a few seconds, an average person starts to lose consciousness. Let's use this information to answer the given question.

Let the maximum burn rate |ΔM/Δt| that the engine could reach before the ship's acceleration exceeded 5 g be x.

Let the mass of the spaceship be m and the exhaust speed of the engine be v.

Using the formula for the thrust of a rocket,

T = (mv)e

After substituting the given values into the formula for thrust, we get:

T = (3.00 × 104)(2.50 × 103) = 7.50 × 107 N

Therefore, the acceleration produced by the engine, a is given by the formula below:

F = ma

Therefore,

a = F/m= 7.50 × 107/3.00 × 104= 2.50 × 103 m/s²

The maximum burn rate that the engine could reach before the ship's acceleration exceeded 5 g is equal to the acceleration that would be produced by a maximum burn rate. Therefore,

x = a/5g= 2.50 × 103/(5 × 9.8)≈ 51.0 kg/s

Therefore, the maximum burn rate ∣ΔM/Δt∣ that the engine could reach before the ship's acceleration exceeded 5 g and its human occupants began to lose consciousness is approximately 51.0 kg/s.

The general indefinite integral is -5x + C.

To find the general indefinite integral of the given expression, we can apply the power rule for integration.

The power rule states that if we have an expression of the form \(x^n\), where n is any real number except -1, the indefinite integral of \(x^n\) with respect to x is given by \((x^(n+1))/(n+1) + C\), where C is the constant of integration.

Applying the power rule to each term in the expression, we have:

∫\((4x^2 - 6 - 4x^2 + 1)\)dx

= (4∫\(x^2\) dx) - (6∫dx) - (4∫\(x^2\) dx) + (∫dx)

= (4(\(x^3/3\))) - (6x) - (4(\(x^3/3\))) + (x) + C

= (4/3)\(x^3\) - 6x - (4/3)\(x^3\) + x + C

= -5x + C

Therefore, the general indefinite integral of the given expression is -5x + C, where C is the constant of integration.

The most effective way to reduce waste is to focus on prevention by avoiding the creation of waste in the first place.

Prevention is considered the most effective strategy for waste management because it addresses the root cause of waste generation. By adopting practices that minimize or eliminate waste creation, we can significantly reduce the environmental impact associated with waste disposal and management. One approach to waste prevention is through source reduction. This involves designing products and processes in a way that minimizes the use of materials, energy, and resources. For example, using efficient manufacturing techniques, optimizing packaging, and promoting reusable or refillable products can help reduce waste at its source. This not only reduces the amount of waste generated but also conserves resources and reduces greenhouse gas emissions associated with production.

Another aspect of waste prevention is promoting sustainable consumption patterns. Encouraging individuals and businesses to make conscious choices, such as buying durable and long-lasting products, repairing and repurposing items, and practicing responsible consumption, can help minimize waste generation. Additionally, implementing recycling and composting programs can divert waste from landfills and promote the recovery and reuse of valuable materials.

By prioritizing waste prevention, we can shift our focus from managing waste to creating a more sustainable and circular economy. This approach requires a shift in mindset and the collaboration of individuals, businesses, and governments. It involves considering the entire lifecycle of products and processes, from design to disposal, and finding innovative solutions that prioritize resource conservation, environmental protection, and long-term sustainability. Ultimately, by not creating waste in the first place, we can minimize the environmental impact, conserve resources, and build a more sustainable future.

It would be equal to twice Eli's yardage plus 122 yards.Eli gained 92 yards rushing during the football game. Samuel gained 30 more yards than Eli.

To find the total number of yards gained by Eli and Samuel, we need to add their individual yardages.

Let's denote Samuel's yardage as S.

Since Samuel gained 30 more yards than Eli, we can write:

S = Eli's yardage + 30

To find the total yardage, we add Eli's yardage and Samuel's yardage:

Total yardage = Eli's yardage + Samuel's yardage

Substituting the values we know, we have:

Total yardage = 92 yards + S

Since S represents Samuel's yardage, we can substitute S with Eli's yardage + 30:

Total yardage = 92 yards + (Eli's yardage + 30)

Combining like terms, we get:

Total yardage = Eli's yardage + Eli's yardage + 30 + 92

Simplifying further, we have equation

Total yardage = 2Eli's yardage + 122

Since we don't have the exact value for Eli's yardage, we cannot determine the total number of yards gained by Eli and Samuel during the game

. However, we can say that it would be equal to twice Eli's yardage plus 122 yards.

The sidereal time tomorrow at 8 p.m. will be 4 hours 56 minutes .

A sidereal day is the amount of time needed by earth to complete one rotation. And the time for one sidereal day is 23 hours 56 minutes and 4.1 seconds. In the solar system , starts appear at the same location at the same time ,each sidereal day. The 4 minutes difference between the solar day and the sidereal day is visible by watching the stars rise 4 minutes earlier every night. So if any star is rising at 7p.m today , it will rise at 6:56 p.m. tomorrow and at 6:52 p.m. the following day.

Similarly if the sidereal time today is 8p.m. , tomorrow it will be four minutes less i.e.  at 4 hours 56 minutes.

Answer:

$72.80

Step-by-step explanation:

You would multiply 52 with .40 to get 20.8. This is how much the price increased by. Then you would add the 20.8 to your original price of 52 to get 72.80.

(Also you use .40 initially because percent means out of 100. So 40% is the same as .4)

The new price after the sale of a new computer is, $72.8

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

The price of the computer was $52 on the day he bought it.

And, The next day it had been marked up by 40%.

Let the new price after the sale of a new computer = x

So, We can formulate;

⇒ x = $52 + 40% of $52

⇒ x = $52 + 40 × 52/100

⇒ x = $52 + $20.8

⇒ x = $72.8

The correct statements are:

The area of the whole pie is 78.5 in.² (true)

The problem is asking for the area of a fractional piece of the pie (true)

The solution is 68.7 in.² (true)

To find the area of the pie that is left after Adrianna cuts and eats a slice, we first need to calculate the area of the whole pie.

The formula for the area of a circle is A = πr², where A represents the area and r is the radius. Given that the diameter of the pie is 10 inches, the radius is half of that, which is 5 inches.

Substituting the values into the formula, we have:

A = 3.14 * (5 inches)²

≈ 3.14 * 25 square inches

≈ 78.5 square inches

Therefore, the area of the whole pie is 78.5 square inches.

Since Adrianna cuts the pie into 8 equal slices, each slice represents 1/8th of the whole pie.

To find the area of one slice, we divide the total area by the number of slices:

Area of one slice = (78.5 square inches) / 8

≈ 9.8 square inches

Therefore, the area of one slice of the pie is approximately 9.8 square inches.

Since Adrianna eats one slice, we subtract the area of one slice from the total area of the pie to find the remaining area:

Remaining area = Total area - Area of one slice

= 78.5 square inches - 9.8 square inches

≈ 68.7 square inches

The equation for the temperature, d, in terms of t (the number of hours since midnight), is:  d = 16 × sin((π/12) × t) + 55

To find an equation for the temperature, we need to determine the amplitude, period, phase shift, and vertical shift of the sinusoidal function.

The amplitude is half the difference between the high and low temperatures, which is (71 - 39) / 2 = 16 degrees. The period is the number of hours in a day, which is 24 hours. Since the temperature is at its highest point at 12:00 PM (midday), there is no phase shift. The vertical shift is the average of the high and low temperatures, which is (71 + 39) / 2 = 55 degrees.

Putting these values together, the equation for the temperature, d, in terms of t can be written as:

d = 16 × sin((2π/24) × t) + 55

⇒ First, factor the numerator by grouping:

⇒ Now, factor the denominator by grouping:

\(=\dfrac{(2e+9)(2e-1)}{2e(f+6)-(f+6)}\\\\\\=\dfrac{(2e+9)(2e-1)}{(2e-1)(f+6)}\)

⇒ We must determine which values of e and f are unacceptable, meaning, will make this expression undefined. These will be the values of e and f that make the denominator equal to 0.

\(=\dfrac{(2e+9)(2e-1)}{(2e-1)(f+6)}\)

A chart that compares three sets of values in a three-dimension chart is called surface.

A two-dimensional collection of points (flat surface), a three-dimensional collection of points with a curved cross section (curved surface), or the perimeter of any three-dimensional solid are all examples of surfaces in geometry.

A surface is typically a continuous boundary that separates two areas of a three-dimensional space. For instance, a sphere's surface divides its interior from its exterior, and a horizontal plane divides the half-planes above and below it. Despite the fact that regions they contain are three-dimensional and have a volume, surfaces are basically two-dimensional and have an area. Despite this, surfaces are frequently referred to by the names of the regions they surround. Differential geometry studies the characteristics of surfaces, particularly the concept of curvature.
