Answer:

Step-by-step explanation:

Number of countries would west Virginia be expected to have is  18 countries

The number of campgrounds that North Dakota has = 465 campgrounds

The number of countries = 12 countries

The number of campgrounds that West Virginia has = 711 campgrounds

Given that the North Dakota was proportional to West Virginia in the number of campgrounds to counties.

The proportion will be

465 / 12 = 711 / x

Divide the terms

38.75 = 711 / x

x = 711 / 38.75

Divide the terms

x = 18.4

x ≈ 18 countries

Hence, number of countries would west Virginia be expected to have is  18 countries

The number of strides the runner will make during 1 hour run will be =

10,800.

To calculate the distance or number of strides made by the runner in an

hour, the graph given above is considered as follows;

The y-axis which represents the number of strides is plotted against the x-axis which is the number of hours.

From the graph

20 minutes= 3600 strides

60 minutes = X strides

make X the subject of formula;

x= 3600×60/20

Solve for n

subtract 6 both sides

6 + 4n-6 > 30-6

4n > 24

divide by 4 on both sides

n > 24/4

n > 6

Answer:

\(\frac{1}{3}\)

Step-by-step explanation:

The computation is shown below:

The numbers of possible results at the time when we drawing in two tries is 9

i.e. shown below:

11, 12, 13, 21, 22, 23, 31, 32, 33

Now the probability is

\(p=\frac{\text{no. of favorable cases }}{\text{total no. of outcomes}}\\\\=\frac{3}{9}\\\\=\frac{1}{3}\)

The graph of g(x) is obtained from the graph of f(x) by the following transformations:

- A horizontal stretch by a factor of 9. This is because the graph of g(x) is 9 times wider than the graph of f(x).

- A vertical translation down by 2 units. This is because the graph of g(x) is 2 units lower than the graph of f(x).

In other words, to obtain the graph of g(x) from the graph of f(x), we stretch the graph horizontally by a factor of 9 and then translate it down by 2 units.

Here is a more detailed explanation of the transformations:

- Horizontal stretch by a factor of 9: To stretch the graph horizontally by a factor of 9, we multiply all of the x-coordinates by 9. This means that every point on the graph of f(x) will be moved 9 units to the right on the graph of g(x).

- Vertical translation down by 2 units: To translate the graph down by 2 units, we subtract 2 from all of the y-coordinates. This means that every point on the graph of f(x) will be moved 2 units down on the graph of g(x).

Answer:

Igloos, Cones (such as ice cream cone), triangles ( such as roofs seen from one ... The tiles need to tessellate to cover an area without leaving any gaps .

Step-by-step explanation:

Any form of tiling involves polygons. The tiles need to tessellate to cover an area without leaving any gaps. This is directly connected to the angle properties of polygons.

Architects include polygons with every plan of a house - rooms usually have 90° corners, but not always. Rooms on a plan are polygons.

The cost of building any structure depends on the lengths of the walls and the size of the angles - all properties of polygons.

If a single free-standing room is to be built, the greatest ratio between the area and the perimeter is in a circle.

The smallest ratio between the area and the perimeter is found in a triangle. The best ratio in tessellating polygons is in a hexagon.

As soon as the cost of doing something one way as compared to another, it becomes a real life issue.

We are surrounded by polygons all the time.

Answer: it has no solutions

Step-by-step explanation:

Factor then solve to find the complex solutions.

Answer:

The magnification is the ratio of the size of the image to the size of the object. In this case, the length of the insect is the size of the object, and the length of the drawing is the size of the image.

To find the magnification, we can divide the size of the image by the size of the object:

Magnification = size of image / size of object

Plugging in the values, we have:

Magnification = 85mm / 23mm

Calculating, we find that the magnification is approximately 3.7. This means that the length of the drawing is 3.7 times the length of the insect.

Answer:

Order of Operations.

Step-by-step explanation:

If we include -7 in the parenthesis, the exponent acts the negative as well. Therefore:

(-7)²= 49.

However, when squaring without the parenthesis, it will give us a negative number because:

The order of operations, or PEMDAS, states that exponents come before multiplication. Therefore, when doing '-7²', you would first need to square the '7', giving us:

-7² = -49

However, within parenthesis, everything inside will be squared.

The given system of equations will have infinite solutions.

Coincident lines are two lines that exactly overlap one another, or we may say that one line exactly lies on top of another one. When simplified, the equations of two concurrent lines are identical.

Two lines that cross one another are said to be coincident lines, and they have an infinite number of solutions. Additionally, the linear equations are consistent.

Here we have

- 6x - 9y = 0 ---- (1)

- 24x = 36y  ----- (2)

Here equation (2) can be written as

=> - 24x - 36y = 0

=>  -6x - 9y = 0 --- (3)

Now the system of equations is

- 6x - 9y = 0    

- 6x - 9y = 0  

Here coefficients of x and y are equal

So given lines are coincident lines.

As we know the solutions of coincident lines are infinite.

Therefore,

The given system of equations will have infinite solutions.

Answer: -1/2

Step-by-step explanation:

To find the slope: rise/run

starting from the point (0,2), you go up 1 to reach the line

Therefore 1 is your rise.

Then go right 2 units and you hit the line again.

Therefore the slope is 1/2.

But the linear line is going downwards, so it is a negative slope

Therefore your final answer is:

Pair 2.

Step-by-step explanation:

For the volumes to be the same the base areas must also be the same.

For Pair 2 the areas are 25π and 24π while the other 2 pairs have both base areas = 25π.

Answer: The slope is −2/3

Step-by-step explanation:

2 x + 3 y = 12  is the standard form for a linear equation. To determine the slope, solve the equation for  y  in order to convert to the slope-intercept form  y = m x + b , where  m  is the slope and  b  is the y-intercept.

2 x + 3 y = 12  

Subtract  2 x  from both sides.

3 y = − 2 x + 12

Divide both sides by  

3 . y = − 2 /3 x + 12 /3 =

y = − 2 /3 x + 4

The slope is

Step-by-step explanation:

Based on the fact that the sum of the interior angles need to be equal to 180°, the missing angle is 110°

The sum of all the interior angles need to add up to 180° which means that to find the missing angle, you should subtract the known angles from 180°.

The missing angle is:

= Total angle - Known angles

Solving for the missing angle gives:

= 180 - 21 - 49

= 180 - 70
