What is volume?

Each thing in three dimensions takes up some space. The volume of this area is what is being measured. The space occupied within an object's borders in three dimensions is referred to as its volume. It is sometimes referred to as the object's capacity.

The radius of Economy Barrel is = 50 cm

The height of Economy Barrel is = 100 cm

The formula for volume of a cylinder is -

Volume = πr²h

Substitute the values into the equation -

Volume = 3.14 × (50)² × 100

Volume = 3.14 × 2500 × 100

Volume = 785000 mL

Now converting it into litres -

785000 / 1000 = 785 Litres

Therefore, Economy barrel can hold 785 litres.

The radius of Oceanview Barrel is = 75 cm

The height of Oceanview Barrel is = 100 cm

The formula for volume of a cylinder is -

Volume = πr²h

Substitute the values into the equation -

Volume = 3.14 × (75)² × 100

Volume = 3.14 × 5625 × 100

Volume = 1766250 mL

Now converting it into litres -

1766250 / 1000 = 1766.25 Litres

Therefore, Oceanview barrel can hold 1766.25 litres.

The radius of Rainforest Barrel is = 75 cm

The height of Rainforest Barrel is = 150 cm

The formula for volume of a cylinder is -

Volume = πr²h

Substitute the values into the equation -

Volume = 3.14 × (75)² × 150

Volume = 3.14 × 5625 × 150

Volume = 2649375 mL

Now converting it into litres -

2649375 / 1000 = 2649.375 Litres

Therefore, Rainforest barrel can hold 2649.375 litres.

The radius of Mountain Flow Barrel is = 100 cm

The height of Mountain Flow Barrel is = 150 cm

The formula for volume of a cylinder is -

Volume = πr²h

Substitute the values into the equation -

Volume = 3.14 × (100)² × 150

Volume = 3.14 × 10000 × 150

Volume = 4710000 mL

Now converting it into litres -

4710000 / 1000 = 4710 Litres

Therefore, Mountain Flow barrel can hold 4710 litres.

Therefore, the florist should go with Rainforest barrel.

Step-by-step explanation:

An equation of the plane through the point (8, 5, 6) and with normal vector 4i 9j 3k is 4x + 9y + 3z = 95.

A plane in geometry is a level surface that never ends. Other names for it include a two-dimensional surface. A plane has an unlimited width, an endless length, zero thickness, and no curvature. The flat surfaces of a cube or cuboid, as well as the flat surface of paper, are all true examples of geometric planes, despite the fact that it is difficult to envision a plane in real life.

A point is given that is (8, 5, 6) and is passing through 4i + 9j + 3k so ,

4(x - 8) + 9(y - 5) + 6(z - 6) = 0

4x + 9y + 3z = 95.

A plane is a flat, infinitely long, two-dimensional surface in mathematics. A plane may appear as a subspace of a multidimensional space, such as one of the room's infinitely expanding walls, or it may live independently on its own, such as in the context of Euclidean geometry.

If A and B matrices have linearly independent column vectors, then the column vectors of C = AB will also has linearly independent column vectors.

Linearly independent vectors are defined when there exists no non-trivial linear combination of the vectors that equals the zero vector. We have, A∈ Rᵐ × Rⁿ and B∈ Rⁿ × Rʳ and C = AB . If both A and B both have linearly independent column vectors. So, A and B are invertible matrix . Then, Cᵀ = Aᵀ Bᵀ where the column vectors of A and B are row vectors of Aᵀ and Bᵀ matrices respectively. Also, the independence of A and B implies the independence of Aᵀ and Bᵀ. As we see Cᵀ = Aᵀ Bᵀ ,then Cᵀ is linearly independent. That means C is invertible matrix . So, the columns of matrix C is also be linearly independent.

Step-by-step explanation:

So 3a + 10c = 125 is translation of first sentence. Second part says a = c+7, "more than" indicating addition.

Substitute the 1st equation's a with c+7

So 3(c+7) + 10c = 125

Distribute.*+

3c + 21 +10c = 125

*Remember that 3(c+7) means to add up

c+ 7

c + 7

c + 7

‐-----------------

3c + 21

Combine 3c + 10c as 13c

So 13c + 21 = 125. Subtract 21 on each side (always treat left and right sides equally, believe in equality for all!!)

13c = 104. Divide each side by 13 (opposite of x)

c = 8........this is cost of each children's ticket

($8). Check: adult ticket is c +7 or $15. Does 3 adult tickets x $15 + 10 child tickets × 8 = 125? 45. + 80 = 125

The 95% confidence interval for the mean daily income of a parking garage is between $5123.48 and $5134.52, indicating that the average daily income will be within this range.

Mean is a form of average that is calculated by adding all of the numbers in a set and then dividing the total number of numbers in the set by the total number of numbers in the set. It is sometimes referred to as the arithmetic average.

Assuming the assumptions given in section a) are correct, the 95% confidence interval for the mean daily income generated by this parking garage may be computed using the method for calculating the confidence interval for a population mean. This confidence interval is computed by taking the sample mean, 5129, and multiplying it by 1.96 times the standard error of the mean, which is the standard deviation divided by the square root of the sample size. As a result, the 95% confidence interval is (5123.48, 5134.52).

This 95% confidence range implies that we can be 95% certain that the average daily income generated by this parking garage will be between $5123.48 and $5134.52. To put it another way, we may be 95% positive that the average daily income in this parking garage is generated.

The number of labor hours required to install the ceiling is 24.528 labor hours.

What is ceiling?

Ceiling is the overhead surface of a room, typically flat and finished with paint, wallpaper, or tiles. It is the highest point or top part of a room, and can be made up of different materials including drywall, plaster, tiles, or even wood. Ceilings also help to separate the room from the outside air and create a space that is more comfortable and insulated. Ceilings can be used to add visual interest to a room, as they can be decorated with different colours and textures. Ceilings can also be used to conceal mechanical and electrical systems, such as wiring, piping, and ductwork.

The number of labor hours required to install the ceiling is 24.528 labor hours. This is determined by multiplying the area of the ceiling (1,856 square feet) by the productivity rate (0.013 labor hours per square foot) and then multiplying that result by the productivity factor (0.95).

Answer:

Step-by-step explanation:

You want the least common multiple (LCM) of {6a²b, 9b²c, 3c²a} and of {4x²y²z², 6x³yz, 12xy²z}.

The LCM of two or more terms is a product that has includes all of the factors of each of the terms. One way to find the LCM is to list the factors of the terms, identify the different ones and the powers of each, then choose the highest power of each of the different factors.

  6a²b — factors are ...

  9b²c — factors are ...

  3c²a — factors are ...

The distinct factors are ...

The product of highest powers is the LCM:

  LCM = 2¹·3²·a²·b²·c² = 18a²b²c²

The distinct factors are ...

The product of the highest powers is ...

  LCM = 2²·3¹·x³·y²·z² = 12x³y²z²

__

Additional comment

Sometimes the process of finding the LCM can be confused with finding the GCF (greatest common factor). The GCF will be the product of the lowest of the powers of the distinct factors. That power may be zero for any given factor in any given term.

For example, in the first set of terms, the factor 2 has a power of 0 in the last two terms. The factor 'a' has a power of zero in the second term; b has a power of 0 in the third term; c has a power of 0 in the first term. Then the GCF is ...

  2⁰·3¹·a⁰·b⁰·c⁰ = 3 . . . . . GCF of {6a²b, 9b²c, 3c²a}

In the second set of terms, 2 has a power of 1 in the 2nd term; 3 has a power of 0 in the 1st term; x, y, z all have powers of 1 in at least one of the terms. Then the GCF is ...

  2¹·3⁰·x¹·y¹·z¹ = 2xyz . . . . . GCF of {4x²y²z², 6x³yz, 12xy²z}

In short, every term must be a factor of the LCM, and the GCF must be a factor of every term.

One way to find the LCM of two terms is to divide their product by their GCF. The process can be repeated to include more terms in the LCM.
