The circumference of a circle is 6.28 kilometers. What is the circle's radius?
Use 3.14 for Pi.

I'm doing this right now too :)

You start by writing the original numbers given into a proportion, which would be

miles          

_____      

hours

Then you have to convert the top unit, miles, into feet. You have to use the rate 1mile:5280 feet. You write that as a proportion too.

miles        1

_____ =  ___

hours      5280

Next, you have to add a conversion rate for changing the hours into seconds. You'd use the rate 1 hour: 60 seconds.

miles        1          60

_____ =  ___  =  ____

hour        5280      1

Then you'd cross multiply to solve.

Answer:

A. 12 centimeters B. 4 centimeters C. 20 centimeters

Step-by-step explanation:

To find area you need to do the Height time the Length.

For A it is 3x4

For B it is 4x1

And for C it is 4x5

You get this equation by multiplying the amount of squares that the Height and Length measured!

The area of the rectangle is 12 units².

The area of the triangle is 2 units².

The area of the trapezium is  16 units.

We have,

The area of the rectangle.

= length x width

= 4 units x 3 units

= 12 units²

The area of the triangle.

= 1/2 x base x height

= 1/2 x 1 unit x 4 units

= 2 units²

The area of the trapezium.

= 1/2 x (sum of the parallel sides) x height

= 1/2 x (5 units + 3 units) x 4 units

=1/2 x 8 units x 4 units

= 4 x 4

= 16 units²

Thus,

The area of the rectangle is 12 units².

Answer:

Cost of one pack = h+8

Step-by-step explanation:

Given that:

Amount Azil have = RM (h²-64)

Packs of flour Azil wants to buy = h-8

To find the price of a pack of flour, we will divide the total amount by packs of flour.

Unit rate = \(\frac{h^2-64}{h-8}\)

Unit rate = \(\frac{h^2-8h+8h-64}{h-8} = \frac{h(h-8)+8(h-8)}{h-8}\)

Unit rate = \(\frac{(h-8)(h+8)}{(h-8)}\)

Unit rate = h+8

Hence,

Cost of one pack = h+8

The number of fiction books in the library is equal to 16

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given the ratio of fiction to nonfiction books in a classroom, the library is 2 to 3, and then the total ratio of both books will be 2+3 = 5. If there are 24 books non-fiction books in the library, to get the number of fiction books that are there we will follow the following steps.

First, we will calculate the total number of books in the shelf;

3/5  x Total number of books = total non fiction books

3/5 * Total number of books = 24

3*Total number of books = 5*24

3*Total number of books = 120

Total number of books = 120/3

Total number of books = 40

Therefore there are 40 total books on the shelf.

Total number of fiction books = 2/5 * 40

Total number of fiction books = 2* 8

Total number of fiction books = 16 books

Hence there are 16 fiction books on the shelf.

The only value that belongs to the solution set is -1

We have the inequality as follows;

|3-2x| < 5

We need to isolate |3 - 2x|.

So, we need to eliminate the absolute value by separating the inequality into two separate inequalities.

The first inequality we have is;

3 - 2x < 5

We will solve for x as follows;

3 - 5 < 2x-2 < 2x+2 < 2-2 < 2x/2-1 < x < 3/2

The second inequality is;

-(3 - 2x) < 5

We will solve for x as follows;

-3+2x < 5-3-5 < 2x-8 < 2x/2-4 < x < 2

So, we have the solution set as;

(-4, -1/2) U (1, 7/2)

The only value that belongs to the solution set is -1,

The missing property?

In step 1, we have:

\(\angle A \cong \angle B,\ \angle C \cong \angle B\)

Transitive property states that:

If \(a = b\) and \(b = c\)

Then \(a = c\)

Similarly:

If \(\angle A \cong \angle B\) and \(\angle C \cong \angle B\)

Por lo tanto, la cantidad de interés que se pagará en el préstamo de 30,000 pesos durante 3 años con una tasa de interés anual del 17.5% es de 16,691.25 pesos.

para calcular la cantidad de interés que se pagará en un préstamo de 30,000 pesos con una tasa de interés anual del 17.5% durante 3 años, es necesario utilizar la fórmula de interés compuesto. Esta fórmula es: I = P * (1 + r)^n - P, donde I es el interés, P es el principal, r es la tasa de interés anual y n es el número de períodos.

En este caso, el principal es 30,000 pesos, la tasa de interés anual es del 17.5%, y el número de períodos es de 3 años. Entonces, podemos calcular el interés utilizando la fórmula:

I = 30,000 * (1 + 0.175)^3 - 30,000 = 16,691.25 pesos.

Once we have established that all three angles are congruent and all three sides are proportional, we can conclude that the two triangles are similar.

To prove that the two triangles are similar, we need to show that all three angles are congruent, and all three sides are proportional.

We know that angle N is congruent to angle Q, but we need to find additional information to prove that the triangles are similar. One possible piece of information could be the length of one side or the ratio of two sides.

If we know the ratio of the lengths of two corresponding sides in the two triangles, we can use that information to show that all three sides are proportional.

Alternatively, if we know the length of one side in both triangles, we can use the angle-angle similarity theorem to show that all three angles are congruent.

A hexagon

Step-by-step explanation:

A hexagon - - - the allen wrench has 2 hexagonal heads. See attached pic.

The geometric shape that forms the hole that fits an allen wrench is a hexagon, which is a six-sided polygon with straight sides and angles.

The geometric shape hexagon-shaped hole in an allen wrench, also known as a hex key, is designed to fit tightly over the hexagonal socket of a screw or bolt head. A hexagon is a six-sided polygon, meaning it has six straight sides and angles. In the case of an allen wrench, the hexagon has internal angles of 120 degrees and opposite sides that are parallel.

The hexagonal shape of the hole in the wrench allows for a tight and secure fit onto the corresponding hexagonal socket of the screw or bolt head. This design ensures that the wrench can apply a significant amount of torque to the fastener without slipping, which is essential for many applications in construction, mechanics, and other industries.

The use of a hexagonal shape also allows for greater precision and control when turning the screw or bolt, making it easier to achieve the desired level of tightness. Overall, the hexagon is an ideal shape for the hole in an allen wrench due to its strength, stability, and precision.

The numbers of the jerseys of 5 randomly selected Carolina Panthers would fall under the category of quantitative discrete data.

Quantitative data are numerical measurements or counts that can be added, subtracted, averaged, or otherwise subjected to arithmetic operations. Discrete data, on the other hand, can only take on specific, whole number values, as opposed to continuous data which can take on any value within a range.

Qualitative data, on the other hand, are non-numerical data that cannot be measured or counted numerically. Examples include colors, names, opinions, and preferences. Since the numbers of the jerseys are specific numerical values, they are considered quantitative data.

Since they can only take on specific, whole number values (i.e. the jersey numbers are not continuous values like weights or heights), they are considered discrete data. Therefore, the correct option for the given question is option "quantitative discrete".

The answer is , an approx. value of m such that the equation cos(x) = mx has exactly two solutions is m = 1 and m = -0.3183

To find an approximate value of m such that the equation cos(x) = mx has exactly two solutions, we can use the fact that the graph of y = cos(x) intersects the line y = mx at exactly two points.

The graph of y = cos(x) is a periodic function with a maximum value of 1 and a minimum value of -1.

Since we want the line y = mx to intersect the graph of y = cos(x) at exactly two points, the slope m must satisfy the condition -1 ≤ m ≤ 1.

Furthermore, for the line y = mx to intersect the graph of y = cos(x) at exactly two points, the line must pass through the maximum and minimum points of the graph of y = cos(x).

These occur at x = 0 and x = π.

At x = 0, we have cos(0) = 1 and the equation cos(x) = mx becomes 1 = m(0), which simplifies to m = 1.

At x = π, we have cos(π) = -1 and the equation cos(x) = mx becomes -1 = m(π), which simplifies to m = -1/π.

Therefore, an approx. value of m such that the equation cos(x) = mx has exactly two solutions is m ≈ 1 and m ≈ -0.3183 (rounded to four decimal places).
