Answer:

It's 14 inches on Ed

Step-by-step explanation:

Final answer:

The volume of the sphere is given as 1372π/3 cubic inches. Using the volume formula for a sphere, V = (4/3)πr³, we calculate the radius and then double it to find the diameter, which is 14 inches.

Explanation:

The student asks for the diameter of the great circle of a sphere, given its volume is 1372π/3 cubic inches. To find this, we'll make use of the formula for the volume of a sphere, V = (4/3)πr³, where V represents the volume and r is the radius of the sphere.

Let's start by equating the given volume to the volume formula:

1372π/3 = (4/3)πr³

Cancelling out π and the fraction (4/3) on both sides, we get:

1372/4 = r³

This simplifies to:

343 = r³

Taking the cube root of both sides gives us the radius:

r = ∛343

r = 7 inches

The diameter of the sphere is twice the radius, so:

diameter = 2r = 2 × 7 = 14 inches

Therefore, the diameter of the great circle of the sphere is 14 inches.

Answer:

A) CD

B)  AB

C) Plane ABCD is parallel to EFGH.

Plane BDFH is parallel to ACGE.

Plane ABFE is parallel to CDHG.

Step-by-step explanation:

We are given the following in the question:

A cuboid  ABCDEFGH is given.

A) line segment that is parallel to AB

A line segment that is parallel to AB is CD.

B) line segment that is skew to AB

Skew lines are the line that never lie in the same plane and never intersect each other.

Thus line segment FH is skew to line segment AB.

C) pair of parallel planes.

Plane ABCD is parallel to EFGH.

Plane BDFH is parallel to ACGE.

Plane ABFE is parallel to CDHG.

There are 432 total barns when multiplying 48 chicken farms by 9 barns per farm. For question number 27, without knowing the number of mice per barn, we cannot determine the exact number of cats needed to control the grain destruction.

To determine the number of total barns if there are 48 chicken farms near an Ohio town and each farm has 9 barns, we simply need to multiply the number of farms by the number of barns per farm. This can be represented by the equation: 48 farms times 9 barns/farm = 432 barns. Therefore, there are 432 total barns.Now, addressing the second question (Number 27): To calculate the number of cats required to control the destruction of stored grain by mice, we need to find out how many mice are in each barn, and then see how many cats are needed to kill that number of mice. A mouse eats 521 ikats of grain each year, and if we are to prevent the destruction of grain in each of the 24 barns, we need to find out how many mice a single cat can kill in a year, and then divide the number of mice by this figure.If one cat kills 96 mice a year, and assuming each barn has the same number of mice, then for one barn: Total mice killed in one barn/year = Number of cats times 96 mice/cat/year. Therefore, to find the number of cats needed: Number of cats = Total mice in one barn/year extdiv 96 mice/cat/year. Without the number of mice, we cannot complete the calculation. More information on the number of mice per barn is required to give a definitive answer.

The final velocity of the sprinter is 7.23 meters per second.

Acceleration of any object is defined as the variation in the speed of the object with the variation of time. Acceleration is a vector term and to define it we require both the magnitude and the direction. The unit of acceleration can be m / sec², miles / sec², etc.

Given that a sprinter starts from rest, and accelerates at 1.87 m/s² over a distance of 14.0 m.

The final velocity will be calculated by the equation of the motion formula as below,

V² = u² + 2as

V² = 2 x 1.87 x 14

V² = 52.36

V = √52.36

V = 7.23 meter per second

Hence, the final velocity is 7.23 meters per second.

Solution to y = 3x - 1: B. (2, 5)

Matching equation for "The sum of -4x and 2 is 9": A. -4x + 2 = 9

Solve x - 6 = -18: A. x = -12

Solve 4x + 3 = 47: A. x = 11

Let's solve each of the given equations one by one:

Solution to y = 3x - 1:

The equation y = 3x - 1 represents a linear relationship between x and y with a slope of 3 and a y-intercept of -1. To find the solution, we can substitute the given options for x and see which one satisfies the equation:

A. (4, 1): 1 = 3(4) - 1 => 1 = 12 - 1 => 1 = 11 (Not a solution)

B. (2, 5): 5 = 3(2) - 1 => 5 = 6 - 1 => 5 = 5 (This is a solution)

C. (4, 3): 3 = 3(4) - 1 => 3 = 12 - 1 => 3 = 11 (Not a solution)

D. (0, -3): -3 = 3(0) - 1 => -3 = 0 - 1 => -3 = -1 (Not a solution)

So, the solution is B. (2, 5).

Matching equation for "The sum of -4x and 2 is 9":

The statement can be translated into the equation: -4x + 2 = 9. So, the correct equation is A. -4x + 2 = 9.

Solving x - 6 = -18:

To solve for x, add 6 to both sides of the equation:

x - 6 + 6 = -18 + 6

x = -12

So, the solution is A. x = -12.

Solving 4x + 3 = 47:

To solve for x, subtract 3 from both sides of the equation:

4x + 3 - 3 = 47 - 3

4x = 44

Now, divide both sides by 4 to isolate x:

(4x)/4 = 44/4

x = 11

So, the solution is A. x = 11.

In summary, the solutions to the given equations are:

B. (2, 5)

A. -4x + 2 = 9

A. x = -12

A. x = 11

Answer: the church was dependent on the princes power

Step-by-step explanation:

The compound inequality which represents the recommendation of economists for a GDP growth rate to be between 7.1 and 7.9 percent (inclusive) is given by '7.1 ≤ g ≤ 7.9'. This mathematical expression indicates that the acceptable rates are all the values including and between 7.1 & 7.9.

In the context of mathematics, specifically the subject of inequalities, the student's question is asking to represent the given GDP rates as a compound inequality. A compound inequality is a statement with two inequalities joined by the word 'and' or 'or'.

Here, economists recommend the GDP growth rate to be between 7.1 and 7.9 percent (inclusive). So, the GDP growth rate (let's denote it as 'g') is more than or equal to 7.1 percent and, at the same time, less than or equal to 7.9 percent. So, the compound inequality which represents this situation is 7.1 ≤ g ≤ 7.9. So the correct option from the provided ones is the first one: '7.1 ≤ g ≤ 7.9'.

This inequality tells us that the growth rates 'g' are all the values including and between 7.1 & 7.9. This is crucial information for economists when monitoring the health and progress of a nation's economy. The percentage rate of GDP growth is a measure of economic success and can impact many aspects like standard of living, employment rates, and business growth.
