We have 390 and we want to find the number thart multiplied by it, will result in 390,000

If we count how many zeros of diffrence between 390 and 390,000 we have, we will notice that:

Therefore, the solution should be 1,000 because:

390 * 1,000 = 390,000

This is the solution we are looking for. Correct answer is B.

Answer:

distributive propriety

Step-by-step explanation:

Step 1 was distributive propriety  because

We distributed the multiplication between 14 and (x+5) over the addition x+5

If we have 14 multiply by a number will just do that. (e.g. 14*3= 42)

If we have 14 multiply by a number written as the sum of others we need to distribute to each part. (e.g. 14*(1+2) = 14*1 +14*2 = 14+28 = 42)

Answer:

2 : 3

Step-by-step explanation:

We'll begin by calculating the area of the entire garden. This can be obtained as follow:

Length of garden (L) = 12 m

Width of garden (W) = 5 m

Area of entire garden (A) =?

A = L × W

A = 12 × 5

Area of entire garden is 60 m²

Next, we shall determine the area of the garden reserved for flower. This can be obtained as follow:

Length of flower garden (L₁) = 12 – 4

= 8 m

Width of flower garden (W₁) = 3 m

Area of flower garden (A₁) =?

A₁ = L₁ × W₁

A₁ = 8 × 3

A₁ = 24 m²

Next, we shall determine the area of the garden reserved for grass. This can be obtained as follow:

Area of entire garden (A) = 60 m²

Area of flower garden (A₁) = 24 m²

Area of grass garden (A₂) =?

A = A₁ + A₂

60 = 24 + A₂

Collect like terms

A₂ = 60 – 24

A₂ = 36 m²

Finally, we shall determine the ratio of the area of the garden reserved for flowers to the area reserved for grass. This can be obtained as follow:

Area of flower garden (A₁) = 24 m²

Area of grass garden (A₂) = 36 m²

Ratio of flower garden to grass garden = A₁ : A₂

= 24 : 36

= 24 / 36

= 2 : 3

Therefore, the ratio of the area of the garden reserved for flowers to the area reserved for grass is 2 : 3

x=0,5

Step-by-step explanation:

Answer:

y = -x-2

Step-by-step explanation:

We are given a slope of -1 and the y intercept of -2

The slope intercept form of the equation for a line is

y = mx+b

where m is the slope and b is the y intercept

y = -1x +-2

y = -x-2

Answer:

y=-x -2

Step-by-step explanation:

Slope-intercept form is

y=mx+b

where m is the slope and b is the y-intercept

We know that the slope is -1. We also know that the y-intercept is (0, -2). For this form, we can disregard the 0, and say the y intercept is just -2.

So, m is -1, and b is -2. Substitute the values into the equation.

y=mx+b

y=-1x+-2

Simplify

y= -x -2

This is the equation of the line in slope-intercept form.

True. The statement "if the range of feasibility indicates that the original amount of a resource, which was 20, can increase by 5, then the amount of the resource can increase to 25" is true.

When a range of feasibility is given, the lower and upper bounds of the values that can be chosen for the variables in a linear programming problem are given. The range of feasibility reflects the range within which the optimum answer can be found. It is a parameter that measures the extent to which the variables can change and still allow the same optimal answer to be obtained.

Eeither A is singular or det(A) = 1.

Let A be a square matrix such that A^2 = A.

If A is singular, then det(A) = 0, and we are done.

Otherwise, let B = A(I - A). Then we have:

B^2 = A(I - A)A(I - A) = A^2(I - A)^2 = A(I - A) = B

Multiplying both sides by B^-1 (which exists since B is invertible), we get:

B^-1 B^2 = B^-1 B

I = B^-1

Now we have:

det(A) = det(B)/det(I - A)

Since B = A(I - A), we have:

det(B) = det(A)det(I - A) = det(A)(1 - det(A))

Substituting into our expression for det(A), we get:

det(A) = det(A)(1 - det(A))/(1 - det(A))

Simplifying, we get:

1 = det(A)

Therefore, either A is singular or det(A) = 1.

We have been given the coordinate plane showing the points (1, 3); (2, 0.6); and (3, 0.12). We need to find the sequence that is modeled by the graph below. Let us analyze the given points of the graph. It can be noticed that the y-values decrease as x increases.

So, it appears that the given graph represents an exponential function with a common ratio that is less than one. Since we have to find the sequence, we need to determine the general term of this sequence.Let a_n be the nth term of the sequence.The general formula for an exponential function is a_n = a_1 r^(n-1), where a_1 is the first term of the sequence and r is the common ratio.We can find a_1 from the given points of the graph.

We see that when x = 1, y = 3. So, a_1 = 3.To find r, we can find the ratio between any two successive terms of the sequence.Let's take the ratio between the second and first term of the sequence.The second term has coordinates (2, 0.6) and the first term has coordinates (1, 3).So, r = 0.6/3 = 0.2.Substituting the value of a_1 and r in the general formula, we get a_n = 3 x (0.2)^(n-1).Therefore, the sequence that is modeled by the given graph is an = 0.3(5)n − 1.I hope this helps.

The set of points in space whose coordinates satisfy a given combination of equations and inequalities can be described by a geometric shape or region in 3-dimensional space.

Enumerate the collection of spatial points whose coordinates fulfil the specified set of equations and inequalities.

The equations and inequalities will define the properties of the region, such as its shape, size, and location.

For example, if we have the equation x + y + z = 3 and the inequality x^2 + y^2 <= 1, the set of points that satisfy these conditions would be the points on or inside a sphere of radius 1 centered at the point (0,0,-1) in the x-y plane, and points on the plane x+y+z = 3.

Another example, if we have the equation x + y = 4 and the inequality y >= 2x-5, the set of points that satisfy these conditions would be the points on the line x+y = 4, above or on the line y = 2x-5.

It's important to note that the type of shape or region that is formed by the equations and inequalities will depend on the specific equations and inequalities being used and the number of variables in the problem.

After answering the provided question, we can conclude that Therefore, trigonometry the helicopter's horizontal distance to the hiker is approximately 388 feet.

The study of the relationship between triangle wall lengths and angles is known as trigonometry. The topic first emerged in the Hellenistic era, around the third century BC, because of the utilization of geometry in astronomical studies. The branch of mathematics known as precise methods deals with certain quaternion functions and about there potential applications in computations. There are six commonly used trigonometric functions in trigonometry. Sine, cosine, tangent, buying new furniture, secant, and cosecant are their person names and acronyms (csc). The study of triangle properties, specially those of right triangles, is known as trigonometry. As a result, geometry is really the study of the properties of all geometric shapes.

We can use trigonometry to solve this problem. Let's start by drawing a diagram:

             Hiker

               /|

              / |

             /  | 1500 ft

            /   |

           /θ   |

          /     |

         /14°   |

        /_______|

     Helicopter

We are looking for the horizontal distance between the helicopter and the hiker, which we can call x. We know the altitude of the helicopter (1500 ft), and we know the angle of depression (14°).

From the diagram, we can see that:

tan(14°) = x / 1500

We can solve for x:

x = 1500 * tan(14°)

x ≈ 387.7 ft

Answer:    Susie needs to find the length of one side of each square pillow and the circumference of the circular pillow, add them all together, and that is how much fringe she must use.

Equation: √3 + √8 + √16 + 2π

(This might not be what you are looking for but this is how I would answer this question)

Step-by-step explanation:

All decimals to 4 decimal places

Area of a square = side x side

To find the length of each side, square root the area

Pillow 1:

Side = √3

Fringe needed = 1.7321

Pillow 2:

Side = √8

Fringe needed = 2.8284

Pilow 3:

Side = √16

Fringe needed = 4

Circumference of a circle = 2πr

radius = half of the diameter

Pillow 4:

Side = 2π(1)

Side = 2π

Fringe needed = 6.2832

Total: 1.7321 + 2.8284 + 4 + 6.2832 = 14.8437

Answer:

Square pillow A:  √3 ft ≈ 1.73 ft (nearest hundredth)

Square pillow B:  √8 ft ≈ 2.83 ft (nearest hundredth)

Square pillow C:  4 ft

Circular pillow:  6.28 ft

Step-by-step explanation:

The area of a square is the square of the measure of its side length.

Therefore, if the customer wants fringe placed on only one edge of each of 3 different square shaped pillows, we can calculate how much fringe should be used for each pillow by square rooting the given areas.

\(\boxed{\textsf{Fringe needed}=\sqrt{\sf Area}}\)

Area = 3 ft²

\(\begin{aligned} \implies \textsf{Fringe needed}&=\sqrt{3\; \sf ft^2}\\&=\sqrt{3}\sqrt{\sf ft^2}\\&=\sqrt{3}\; \sf ft\\&\approx1.73 \sf \; ft\;(nearest\;hundredth)\end{aligned}\)

Area = 8 ft²

\(\begin{aligned} \implies \textsf{Fringe needed}&=\sqrt{8\; \sf ft^2}\\&=\sqrt{8} \sqrt{\sf ft^2}\\&=\sqrt{8} \; \sf ft\\&\approx 2.83\; \sf ft\;(nearest\;hundredth)\end{aligned}\)

Area = 16 ft²

\(\begin{aligned} \implies \textsf{Fringed needed}&=\sqrt{16\; \sf ft^2}\\&=\sqrt{16}\sqrt{\sf ft^2}\\&=4 \; \sf ft\end{aligned}\)

If the same customer also has a circular pillow that is 2 ft in diameter and they want fringe placed all the way around it, we can calculate the amount of fringe to use by calculating the circumference of the circle.

The formula for a circumference of a circle is C = πd, where d is the diameter of the circle.  Given that d = 2 ft and using π ≈ 3.14:

\(\begin{aligned}\implies \textsf{Fringe needed for the circular pillow}&=\pi \cdot 2\\&=3.14 \cdot 2\\&=6.28\; \sf ft\end{aligned}\)

The closest estimate for the experimental probability of rolling a 4 on the cube is 0.116.

Probability is a metric used to determine how likely an event is to take place. Often, it is stated as a number between 0 and 1, with 0 denoting an impossibility and 1 denoting a certainty. With a typical six-sided dice, for instance, the likelihood of rolling a 1 is 1/6 or around 0.167.

Several techniques can be used to determine probability, depending on the circumstance. When rolling a fair die, for example, the likelihood of each potential result is equal and may be estimated using the formula:

Amount of favorable outcomes / Total number of potential outcomes is how you calculate an event's probability.

Given that, cube numbered from 1 through 6 is rolled 500 times.

The experimental probability of 4 landing face-up on the cube is:

Experimental probability = Number of times 4 lands face-up / Total number of rolls

Experimental probability = 58 / 500 = 0.116.

Hence, the closest estimate for the experimental probability of rolling a 4 on the cube is 0.116.

The equation of a line that is perpendicular to another line, we need to determine the slope of the original line and then find the negative reciprocal of that slope.

Given that the line passes through the point (4,2), we can assume that this point lies on the perpendicular line. Let's first find the slope of the original line. Since we don't have the equation of the line, we can assume it's in the form y = mx + b, where m represents the slope. We need more information to find the value of m.

Now, let's find the slope of the perpendicular line. Since it is perpendicular to the original line, its slope will be the negative reciprocal of the original line's slope. Let's say the slope of the original line is m, then the slope of the perpendicular line will be -1/m. We are given a point (4,2) that lies on the perpendicular line.

Using the point-slope form of a line, y - y1 = m (x - x1), we can substitute the values of x1, y1, and m to find the equation of the perpendicular line. Let's say the equation of the perpendicular line is y = mx + c, where c represents the y-intercept.

Using the point (4,2) and the slope -1/m, we can substitute these values into the equation y - y1 = m (x - x1) to find c. Once we have the value of c, we can substitute it back into the equation y = mx + c to get the final equation of the perpendicular line.
