Answer:

Step-by-step explanation:

If the diameter of the tub is 8 inches, then the height of gallon tube is,  5.25 inches

Surface area is the sum of the areas of all the faces (or surfaces) of a three-dimensional object. It is a measure of how much area the surfaces of an object take up in two dimensions. The surface area of a solid can be found by adding up the areas of its faces.

The surface area of a cylinder can be expressed as:

SA = 2πr² + 2πr x h

where r is the radius of the cylinder, h is its height, and π is the constant pi (3.14).

The diameter of the tub is 8 inches, which means the radius is 4 inches. We are also given that the total surface area is 232.36 square inches.

So we can write:

232.36 = 2(3.14)(4²) + 2(3.14)(4)(h)

Simplifying and solving for h, we get:

232.36 = 100.48 + 25.12h

131.88 = 25.12h

h = 131.88/25.12

h ≈ 5.25 inches

Therefore, the height of the ice cream tub is approximately 5.25 inches.

Answer: the maximum score was 10 feet.

Step-by-step explanation:

here's a step-by-step explanation:

Identify the minimum score: The minimum score is given in the problem as 4 feet.

Identify the range: The range is also given in the problem as 6 feet.

Calculate the maximum score: To find the maximum score, we simply need to add the minimum score and the range.

Maximum score = Minimum score + Range

Maximum score = 4 feet + 6 feet

Maximum score = 10 feet

So the maximum score was 10 feet.

The number line of the inequality is (d)

from the question, we have the following parameters that can be used in our computation:

3x+2≤4x+5≤9

When this is expanded, we have

3x + 2 ≤ 4x + 5 and 4x + 5 ≤ 9

Evaluate the like terms

So, we have the following representation

-x ≤ 3 and 4x ≤ 4

Divide by the coefficient of x

x ≥ -3 and x ≤ 1

When combined, we have

Answer:

Step-by-step explanation:

To find the probability of the sum of two randomly selected numbers from a set being greater than 12, we need to first find the total number of possible combinations of two numbers and then count the number of combinations that result in a sum greater than 12.

The set contains four numbers, so there are 4 choose 2 possible combinations of two numbers, which is equal to (4! / (2! * (4 - 2)!)), or 6 combinations. These combinations are:

(0,6), (0,12), (0,15), (6,12), (6,15), (12,15)

Next, we'll count the number of combinations that result in a sum greater than 12. These combinations are:

(6,15), (12,15)

There are 2 combinations that result in a sum greater than 12.

Finally, to find the probability, we'll divide the number of favorable outcomes (combinations with a sum greater than 12) by the total number of outcomes (all possible combinations of two numbers), and express the result as a fraction:

probability = 2 / 6

Reducing the fraction, we get:

probability = 1 / 3

So, the probability that the sum of two randomly selected numbers from the set is greater than 12 is 1/3.

That's how you find the probability of the sum of two randomly selected numbers from a set being greater than a certain value. By counting the number of favorable outcomes and dividing by the total number of possible outcomes, you can find the probability of a certain event.

The linear equation can be written as:

y = (3/2)*x - 21/5

A general linear equation can be written as:

y = m*x + b

Where m is the slope and b is the y-intercept.

First, we know that our line has the same slope than:

3x - 2y = 12

Rewriting that we will get:

3x - 2y = 12

3x - 12 = 2y

(3/2)x - 12/2 = y

So the slope of this line is (3/2).

And our lie has the same y-intercept as 5y + 21 = 4x

We can rewrite that to get:

5y = 4x - 21

y = (4/5)x - 21/5

The y-intercept is -21/5

Then the linear equation is:

y = (3/2)*x - 21/5

Answer: 523.3cm^3

Step By Step Explanation:-The volume of a sphere can be calculated using the formula:

V = (4/3) * π * r^3

where r is the radius of the sphere. The diameter of the sphere is 10 cm, so the radius is half of that, or 5 cm.

Substituting the radius into the formula, we get:

V = (4/3) * π * (5 cm)^3

= (4/3) * π * 125 cm^3

= approximately 523.6 cm^3

So, the closest measurement to the volume of the sphere in cubic centimeters is approximately 523.3 cm^3.

The equation (p+1)x² + (2p+3)x+ (p+2)=0 has real roots for all real values of p at x = -1, -2

A polynomial equation is a mathematical equation in which the polynomial is set to zero. The equation is made up of variables, non-negative integer exponents, coefficients, arithmetic operations, and an equal sign.

Given that:

(p+1)x² + (2p+3)x + (p+2) = 0

Open brackets;

px² + x² + 2px + 3x + p + 2 = 0

Move all terms not containing p to the right side of the equation.

px² +  2px + p = −x² − 3x − 2

Factor p out of px² + 2px + p.

p(x² + 2x + 1) = −x² − 3x − 2

Factor using the perfect square rule.

p(x+1)² = −x² − 3x − 2

Divide each term in p( x + 1 )² = −x² − 3x − 2 by (x + 1)² and simplify.

[tex]p= - \dfrac{x^2}{(x+1)^2}-\dfrac{3x}{(x+1)^2}-\dfrac{2}{(x+1)^2}[/tex]

Set [tex]p= - \dfrac{x^2}{(x+1)^2}-\dfrac{3x}{(x+1)^2}-\dfrac{2}{(x+1)^2}[/tex] to be equal to zero;

[tex]- \dfrac{x^2}{(x+1)^2}-\dfrac{3x}{(x+1)^2}-\dfrac{2}{(x+1)^2}=0[/tex]

Solve for x;

-x² - 3x - 2 = 0

Factor the left side of the equation.

-(x + 1) (x + 2) = 0

x = -1

x = -2

The final solution is all the values that make -(x + 1) (x + 2) = 0 true

x = -1, - 2

Exclude the solutions that do not make  [tex]- \dfrac{x^2}{(x+1)^2}-\dfrac{3x}{(x+1)^2}-\dfrac{2}{(x+1)^2}=0[/tex] true.

Answer:

The circumference of one of the semicircles with a radius of 7 meters would be approximately 21.98 meters.

Step-by-step explanation:

The circumference of a circle can be calculated using the formula:

C = 2πr

where C is the circumference, π (pi) is approximately equal to 3.14, and r is the radius of the circle.

For a semicircle with a radius of 7 meters, the circumference can be calculated as follows: Because the semicircle is a half circle, then:

C = (2πr)/2= 3.14 × 7 = 21.98 meters

So, the circumference of one of the semicircles with a radius of 7 meters would be approximately 21.98 meters.

Answer:

The circumference of one of the semicircles is 21.98 m.

Step-by-step explanation:

The formula for the circumference of a circle is C = 2πr, where r is the radius of the circle.

A semicircle is half a circle, therefore the length of the curved part of the circumference of a semicircle is half the circumference of a circle: πr.

Given the radius of one of the semicircles is 7 m and π ≈ 3.14, the circumference of the semicircle is:

⇒ C = 3.14 · 7

⇒ C = 21.98 m

The volume of the composite figure is 2592 cubic feet.

The area that any composite shape covers is known as the area of composite shapes. The composite shape is a shape created by joining a small number of polygons to create the desired shape. These shapes or figures can be constructed from a variety of shapes, including triangles, squares, quadrilaterals, etc. To calculate the area of a composite object, divide it into simple shapes such a square, triangle, rectangle, or hexagon.

The volume of the figure = Volume of the mounted object + Volume of the base object.

The volume of the mounted object is:

V = (l)(b)(h)

V = (9)(12)(6)

V = 648 cubic feet.

The volume of the base object is:

V = (l)(b)(h)

V = (27)(12)(6)

V = 1944 cubic feet.

The total volume of the composite figure is:

V = 648 + 1944

V = 2592 cubic feet

Hence, the volume of the composite figure is 2592 cubic feet.
