The radius of a sphere is 3 inches. Which represents the volume of the sphere?

1. Only constraint 2 would be met if 18 pairs of leather boots and 36 pairs of running  shoes were ordered.

2. Only constraint 1 would be met if 12 pairs of leather boots and 36 pairs of running shoes were ordered.

Data and Calculations:

Total pairs of shoes required = 48 pairs

Running shoes required (r) = 2 of leather boots

Leather boots required (b)= 1/2 of running shoes

Constraint 1:

The total pairs of different shoes required:

Running shoes = 32r

Leather boots = 16b

Total pairs = 32r + 16b = 48

Constraint 2:

Ratio equation:

Running shoes = 2r

Leather boots = b

Equation = 2r + b = 48

Thus, Constraint 2 satisfies the first order, while Constraint 1 satisfies the second order. The two constraints do not satisfy the two orders.

Amanda needs 48 pairs of shoes total, with twice as many running shoes as leather boots. Constraint 1 is x + y = 48, and constraint 2 is y = 2x. An order of 18 boots and 36 running shoes meets only constraint 2, while 12 boots and 36 running shoes meet both constraints.

Amanda needs to order a total of 48 pairs of shoes, with twice as many pairs of running shoes as leather boots. To set up the equations, let x represent the number of pairs of leather boots and y represent the number of pairs of running shoes.

Constraint 1:

The total number of pairs of shoes:

x + y = 48

Constraint 2:

The ratio of the number of running shoes to leather boots:

y = 2x

To check which constraints are met by given orders:

1. For 18 pairs of leather boots (x = 18) and 36 pairs of running shoes (y = 36):

Using constraint 1: 18 + 36 = 54. This does not meet constraint 1.

Using constraint 2: 36 = 2(18). This meets constraint 2.

2. For 12 pairs of leather boots (x = 12) and 36 pairs of running shoes (y = 36):

Using constraint 1: 12 + 36 = 48. This meets constraint 1.

Using constraint 2: 36 = 2(12). This meets constraint 2.

Answer:

ALL REAL NUMBERS

Step-by-step explanation:

Any quadratic function is ALWAYS R.

The answer can be stated as "The solution to a system of two linear equations in two variables corresponds to the intersection of straight lines represented by them."

To represent a straight line on a graph consider two points namely x and y intercepts of the line. To find x-intercept put y = 0 and for y-intercept put x = 0. Then draw a line passing through these two points.

A system of linear equation in two variables can be written as,

a₁x + b₁y + c₁ = 0

a₂x + b₂y + c₂= 0

In order to find their solution these equations are solved either by substitution or elimination.

A linear equation in two variable represents a straight line.

Thus, the solution to these equations are the coordinates of the intersection point of these two lines.

Hence, the solution to a system of linear equation in two variables indicate the coordinate of their intersection.

Answer:

The dimensions of the garden are

Length [tex]25.5\ ft[/tex]  and Width [tex]16.5\ ft[/tex]

Step-by-step explanation:

Let

x----> the length of the rectangular garden

y ---> the width of the rectangular garden

Aw ----> the area of the walkway

we know that

[tex]x=y+9[/tex] ----> equation A

[tex]Aw=(x+8)(y+8)-xy[/tex]

[tex]Aw=400\ ft^{2}[/tex]

so

[tex]400=(x+8)(y+8)-xy\\400=xy+8x+8y+64-xy[/tex]

[tex]400=8x+8y+64[/tex] ----> equation B

Substitute equation A in equation B

[tex]400=8(y+9)+8y+64[/tex]

[tex]400=8y+72+8y+64[/tex]

[tex]400=16y+136[/tex]

[tex]16y=400-136[/tex]

[tex]y=16.5\ ft[/tex]

Find the value of x

[tex]x=16.5+9=25.5\ ft[/tex]

therefore

The dimensions of the garden are

Length [tex]25.5\ ft[/tex]

Width [tex]16.5\ ft[/tex]

[tex]m^{24}n^{18}[/tex]

We can distribute the terms using the distributive property first. [tex](m^4)^6 * (n^3)^6[/tex]

Then, use the power of a power property to multiply the powers. [tex]m^{4*6} * n^{3*6} = m^{24}n^{18}[/tex]

The value of n and the distance from Point B to Point C cannot be determined without specific coordinates for these points. Given that B is the midpoint between points A and C, the x-coordinate for Point B should be n/2. The distance between the points would be calculated using the distance formula derived from the Pythagorean Theorem.

To calculate the distance between points in a graph, we typically use the distance formula, which is derived from the Pythagorean Theorem. From our given information, Point A lies on the y-axis and has the same y-coordinate as Point B. Point C is graphed at (n, -3). Given that the distance is the same from Point B to both points A and C, this implies that Point B is the midpoint between Points A and C. The coordinates of the midpoint are obtained by averaging the x and y coordinates of the two points. Therefore, the x-coordinate of Point B must be n/2.

The distance from Point B to Point C (or similarly to Point A) can be obtained using the distance formula: sqrt((x2−x1)² + (y2−y1)²), where x1, y1 are the coordinates of one point and x2, y2 are the coordinates of the other point.

However, without concrete values for some of these points in the given equation, we cannot provide a specific numerical value for the distance or n. This calculation depends specifically on the placement of the points on the graph.

Answer:

Dist = 45 m/h * x h

Step-by-step explanation:

We know a speed is a measure of distance over time:  speed = dist / time

In this case, we are looking for a distance expressed in terms of time.

So, we only need to modify the formula a bit: dist = speed * time

We don't know the time (which will be a variable), but we know their speed.  So, the formula becomes:

Dist = 45 m/h * x h

Enter the number of hours in the formula and that will give you an approximation of the distance traveled within that time (approximation since our result will be rely on an average).

5 sqrt 3i is the correct answer

Answer: b) √108

c√18.√6

e)√3.√36

Step-by-step explanation:

We know that, for example, √4 = √2² = 2

As the index of the number inside the root maches the index of the root, we can remove it from the root.

And the inverse process is also correct, so 2 can be written as

√2² = √4, this way:

6√3 = √3.√6² = √3.√36 = √108

a) √54 ≠ √108

b) √108 = √108 ok

c) √18.√6 = √108 ok

d) √3.√6 = √18 ≠ √108

e) √3.√36 = √108 ok

f) 108 ≠ √108

Answer:

The answer to this problem is 22.

Step-by-step explanation:

To solve this problem, we simply need to plug in the values given for a and b into the expression given and simplify.

We are given that a=3 and b=4, thus, these are the numbers we will plug in before we simplify.

2a^2 + b =

2(3)^2 + 4

Next, we should follow the rules of PEMDAS.  This tells us that we should solve the parentheses first, but since there are no parentheses, we can move onto exponents.

If we simplify, we get:

2(9) + 4

Next, we should perform the multiplication.

18 + 4

Finally, we can add together the remaining terms.

18 + 4 = 22

Therefore, your answer is 22.

Answer:

4x^2 - 12x + 9

Step-by-step explanation:

Please use " ^ " to denote exponentiation:  4x^2 - 12x + 9.

This 4x^2 - 12x + 9 factors into (2x - 3)^2, and is thus a perfect square trinomial.

The polynomial [tex]4x^2-12x + 9[/tex] is a perfect square trinomial. It has a binomial factor (2x - 3).

The product of a binomial by itself gives the perfect square trinomial.

A trinomial is a polynomial that has only three terms and A binomial is a polynomial that has only two terms.

A. Trinomial  [tex]4x^2-12x+9[/tex]

⇒ [tex](2x)^2-2(2x)(3)+(3)^2[/tex]

This is in the form of [tex]a^2-2ab+b^2[/tex] . So, we can write [tex](a - b)^2[/tex]

⇒ [tex](2x - 3)^2[/tex] or (2x - 3)(2x - 3)

Thus, this is a perfect square trinomial.

B. Trinomial [tex]16x^2+24x-9[/tex]

⇒ [tex](4x)^2+2(4x)(3)-(3)^2[/tex]

Since it cannot split into a binomial square, this trinomial is not a perfect square trinomial.

C. Trinomial [tex]4a^2-10a+25[/tex]

⇒ (2a)^2-2(5a)+(5)^2

This cannot be split into a binomial square, this is not a perfect square trinomial.

D. Trinomial [tex]36b^2-24b-16[/tex]

⇒ [tex](6b)^2-2(6b)(2)-(4)^2[/tex]

So, this is not a perfect square trinomial.

Therefore, the trinomial at option A is a perfect square trinomial.

To calculate the area of triangle ABC with sides measuring 8, 11, and 15 units, Heron's formula is used. The semiperimeter s is 17 units, which leads to an area of the square root of 1836 or approximately 42.8 square units.

Explanation:

To find the area of triangle ABC with sides a = 8, b = 11, and c = 15, we can use Heron's formula, which is a method of finding the area of a triangle when you know the lengths of all three sides. The formula states that the area of a triangle is the square root of s(s-a)(s-b)(s-c) where s is the semiperimeter of the triangle, or half of the triangle's perimeter. First, we calculate the semiperimeter: s = (a + b + c) / 2. Then, we substitute the values of a, b, and c into the formula to find the area.

The semiperimeter s is (8 + 11 + 15) / 2 which equals 17. Using Heron's formula, the area is the square root of 17(17-8)(17-11)(17-15). Therefore, the area of triangle ABC is equal to the square root of 17  imes 9  imes 6  imes 2, which simplifies to the square root of 1836, resulting in an area of 42.8 square units.

Answer:

The correct option is B) zero x = -2.

Step-by-step explanation:

Consider the provided graph y = x + 2

The zeros of a function are the point on which graph intersects the x axis or we can say the value of x when y = 0.

Substitute y = 0 in the provided equation.

0 = x + 2

x = -2

The coordinate is (-2,0). Also the zero of the graph is at x = -2 because it follows the definition of zeros.

Now substitute x = 0 in the provided equation.

y = 0 + 2

y = 2

The coordinate is (0,2).

Now, draw a line passing through the point (-2,0) and (0,2).

The required line is shown in figure 1.

Now consider the provided options only option A and B have the same graph.

But the correct option is B as the zero of the option B is x = -2.

Hence, the correct option is B) zero x = -2.

Explanation of graphing y=x+2 and finding its zero. Find the correct graph and x-intercept.

Graph: First, graph the equation y = x + 2. This is a straight line with a slope of 1 (rise of 1, run of 1) and y-intercept at 2.

Zero of the function: To find the zero of the function (where y = 0), set x + 2 = 0 and solve for x. In this case, x = -2.
