Answer:

Step-by-step explanation:

0.947 g/ml is the cube density the volume was 9.01.

The term "density" refers to the ratio between the volume (the amount of space taken up by an item or substance) and the amount of matter contained inside (its mass). The quantity of mass per unit of volume is another method to define density.

We are know that items float in liquids when their density is less than that of the liquid.

Objects floating in a liquid are those whose density is equal to that of the liquid.

So, in this case, the cube is solely suspended in the first liquid combination. Therefore, the first liquid mixture's density is the same as a cube. The other mixes have densities that are higher than that of the cube.

Density of methanol = 0.7913 g/ml

Density of water = 1 g/ml

Density of the 6th liquid mixture:

= {(2 × 0.7913 ) + (1 × 6)}/8 g/ml

= 0.947 g/ml

Therefore density of cube = 0.947 g/ml

The cost of a 32-ounce container is 2.92 and the cost of 6 8-ounce containers is $4.18.

Word problems are sentences describing a 'real-life' situation where a problem needs to be solved by way of a mathematical calculation.

Let's call the unit price of 8-ounce yogurt x.

32-ounce unit price = x + 0.002

32-ounce container cost = 32 * (x + 0.002) =0.064 + 32x

6 * 8-ounce container cost = 6 * 8 * x = 48x

Given, 32-ounce container cost = 6 * 8-ounce container cost - $1.33

Substituting the costs,

0.064 + 32x = 48x - 1.33

Solving for x,

48x - 32x = 0.064 + 1.33

16x = 1.394

x = $0.087125

So, the unit price of 8-ounce container is $0.087125

Cost of 32-ounce container = $0.064 + 32 * (0.087125 + 0.002) = $2.92

Cost of 6 8-ounce containers = 6 * 8 * 0.087125 = $4.18.

The equation for the volume of a cylindrical shell is:

V = πr² * h * w, where r is the radius of the semicircle base, h is the height of the shell, and w is the width of the shell.

The volume of the solid can be found using the method of cylindrical shells. The volume of each cylindrical shell is equal to the product of the area of the base (a semicircle), the height of the shell, and the width of the shell (which is equal to the difference in the x-coordinates of the two vertices that define the height).

To find the total volume, we would sum up the volumes of all the cylindrical shells, from the top to the bottom of the solid.

The equation for the volume of a cylindrical shell is:

V = πr² * h * w, where r is the radius of the semicircle base, h is the height of the shell, and w is the width of the shell.

The standard form of a circle is given by ⇒ (x - h)² + (y - k)² = r²,

where (h, k) is the center of the circle and r is the radius.

To find the standard form of the circle that has center (6, 1) and a solution point (5, 9), we need to find the radius "r" first.

The distance(r)  between the center and the solution point is given by the Pythagorean theorem:

⇒ r = √((5 - 6)² + (9 - 1)²)

⇒ r = √((-1)² + (8)²)

⇒ r = √65

Now substituting  radius(r = √65) in  the standard form of the circle:

Ponyboy shivered as he recalled the Socs jumping him and asking if he was a greaser.

The statement is referencing a scene from the novel "The Outsiders" by S.E. Hinton. In the novel, Ponyboy is a member of a poor, lower-class gang called the "greasers." The Socs are the wealthier, more privileged gang in town. The scene described in the statement is likely one in which Ponyboy is confronted and beaten up by members of the Socs gang, who are asking him if he is a member of the greaser gang.

The scene highlights the tensions and conflicts between the two gangs and their different experiences growing up in different social classes.

"The Outsiders" is considered a young adult novel, so it can be read by kids who are at or near the target age range for that genre, typically around 12 to 18 years old. However, the themes and content of the novel may be mature for some younger readers, so it is always a good idea for parents or guardians to read the book first and determine if it is appropriate for their child.

The length of sides are proportional in similar triangles.

Given a figure of a big triangle.

We can clearly see that angles made by each of the triangles ALE, BKE, CHE and DGE are equal and thus they are similar triangles.

The sides of similar triangles are proportional.

DG / GE = CH / HE = BK / KE = AL / LE

We have DG = 3, GE = 5,HG = 5, KH = 5, LK = 5

HE = 5 + 5 = 10

KE = 5 + 5 + 5 = 15

LE = 5 + 5 + 5 + 5 = 20

Substituting,

Consider DG / GE = CH / HE

3 / 5 = CH / 10

CH = (3/5) × 10 = 6

Consider DG / GE = BK / KE

3 / 5 = BK / 15

BK = (3/5) × 15 = 9

Consider DG / GE = AL / LE

3 / 5 = AL / 20

Probability that the customer is either older than 40 or younger than 20:

The equation of the plane that passes through (1, 3, 6) and is parallel to x = 11 is x = 1.

An algebraic expression is a mathematical phrase that can contain numbers, variables, and operations (such as addition, subtraction, multiplication, and division). It represents a value that can be determined if the values of the variables are known. An algebraic expression does not contain an equal sign and cannot be solved like an equation, but it can be simplified or manipulated using algebraic rules. For example, the expression 2x + 3y is an algebraic expression, where x and y are variables.

A plane can be represented by a normal vector (a,b,c) and a point (x⁰,y⁰,z⁰) that lies on the plane. If a plane is parallel to the plane x = 11, the normal vector must be in the direction of the x-axis, meaning (a,b,c) = (1,0,0).

The equation of the plane can then be found using the point-normal form, which is given by:

ax + by + cz = d, where d = ax⁰ + by⁰ + cz⁰

Plugging in the values for (1,3,6) and (a,b,c) = (1,0,0), we get:

a(1) + b(3) + c(6) = d

1 + 0 + 0 = d

d = 1

The segment drawn from the apex to the edge of the circular base is 24.2 units.

A right triangle's hypotenuse, or side opposite the right angle, has a square length that, according to the Pythagorean theorem, is equal to the sum of the squares of the lengths of the other two sides.

The Pythagorean Theorem can be used to determine the slant height of a right cone. The circular base's radius is equal to its diameter times half, or 6/2 = 3 units.

The volume of the cone can be found using the formula:

V = (π/3)r²h

Where r is the radius, and h is the height of the cone. Plugging in the given values, we have:

72π = (π/3)r²h

72π = (π/3)3²h

72π = (π/3)9h

72π = 3πh

24 = h

Using the Pythagorean Theorem, we can find the slant height as follows:

c² = a² + b²

Where a and b are the height and radius of the cone, and c is the slant height. Plugging in the values we have:

c² = 24² + 3²

c² = 576 + 9

c² = 585

c = 24.2

Hence, the segment drawn from the apex to the edge of the circular base is 24.2 units.

Joint variation describes a situation in which, while the other variables are held constant, the value of one variable relies on the values of two or more additional variables.

Joint variation is used to describe when more than two variables are directly correlated or when one variable changes as a result of the change product of more than two variables. X can be symbolically expressed as X YZ if it is in joint variation with Y and Z. If Y is also constant, then X and Z directly depend on one another.
