Answer:

The diameter of the floor is 6 yards

Step-by-step explanation:

Here, we are to calculate the diameter of a circular floor that has a circumference of 18.84 yards

Mathematically,

C = π * D

where C is the circumference

Plugging the values of the circumference , we have ;

18.84 = 22/7 * D

7 * 18.84 = 22D

D = (7* 18.84)/22 = 5.99 which is approximately 6 yards

Answer: Choice B.

Step-by-step explanation:

Censuses are complete data collections of every member of a population.

For example, the U.S. Census occurs every 10 years and documents every member of the American population.

Choice A only surveys the first ten students; this is not a complete census.

Choice B surveys all the students in the targeted data group. This is a census.

Choice C only surveys the male students, even though there are female students in his data group. This is not a census.

Choice D only surveys the girls on the soccer team, even though there may be boys on the team as well. This is not a census.

Choice E only surveys his friends in the chorus, even though there may have been people that were not his close friends. This is not a census.

Only choice B is a complete census.

Answer:

choice B

Step-by-step explanation:

because choice b is the only complete census  

Answer:

- In a 3-D setting, straight line aa can be perpendicular or parallel to straight line cc.

- In a 2-D setting, straight line aa can only be parallel to straight line cc.

- W ustawieniu trójwymiarowym linia prosta aa może być prostopadła lub równoległa do linii prostej cc.

- W ustawieniu 2-D linia prosta aa może być równoległa do linii prostej cc.

Step-by-step explanation:

English Translation

Straight line aa and straight line bb are perpendicular to each other, as well as straight line bb and straight line cc are perpendicular to each other. Choose the correct completion of the sentence. Line aa is perpendicular / parallel to line cc.

Solution

If the frame of reference for the lines is in 3-D, then, it is the straight line aa can also be perpendicular to the straight line cc in the same vein as the x, y and z component lines are usually all perpendicular to one another. Note that straight line aa could also be parallel to straight line cc in a 3-D frame of reference.

But in a 2-D frame of reference, straight line aa can only be parallel to straight line cc. This is because the only directions that straight line bb can be perpendicular to, in a 2-D setting, are all in the same parallel direction.

In Polish/Po polsku

Jeśli układ odniesienia dla linii jest w 3-D, to jest to linia prosta aa może być również prostopadła do linii prostej cc w tej samej żyle, ponieważ linie składowe x, y i z są zwykle wszystkie prostopadłe do jednego inne. Należy zauważyć, że linia prosta aa może być również równoległa do linii prostej cc w trójwymiarowym układzie odniesienia.

Ale w dwuwymiarowym układzie odniesienia linia prosta aa może być tylko równoległa do linii prostej cc. Jest tak, ponieważ jedyne kierunki, w których prosta bb może być prostopadła, w ustawieniu 2-D, wszystkie są w tym samym kierunku równoległym.

Answer:

$250 + $23x

Step-by-step explanation:

One time set-up fee for jerseys = $250

cost of one jersey = $23

therefore, cost x jersey = cost of one jersey*x = 23x

Total cost for this deal will be sum of  One time set-up fee for jerseys and cost x jersey

Total cost = One time set-up fee for jerseys + cost x jersey

Total cost =  $250 + $23x

Expression represents the total cost of x number of jerseys for the team is  $250 + $23x.

Answer:

|-3| - |6| = 9

| 6 - -3| = | 6+3| = 9

Step-by-step explanation:

The distance between points is given by

d = sqrt( (x2 -x1) ^2 + (y2-y1) ^2 )

Since the y coordinates are the same

d = sqrt( (x2 -x1) ^2  )

d = sqrt( x2-x1)^2)

Or the distance between the two points

The distance between them is 9 units

|-3| - |6| = 9

| 6 - -3| = | 6+3| = 9

Answer:3,969[tex]^{2}[/tex](squared) or 63

Step-by-step explanation:

First you must plug the answers into the equation A[tex]^{2}[/tex] + B[tex]^{2}[/tex]=C[tex]^{2}[/tex]

Then you square the numbers. example: 2[tex]^{2}[/tex]=2 x 2=4

After that you subtract from both sides of the equation to get the variable by itself.     Example:   4+b[tex]^{2}[/tex]=10    

                              -4       -4

                                 b[tex]^{2}[/tex]=10

After that you square both sides or you could say answer[tex]^{2}[/tex]

Answer:

The cost of the carpet at Magic Carpet is: 90 + 9*(area of carpet)

The cost of carpet at Carpeteria is: 50 + 13*(area of carpet)

The algebraic expression for which the cost is the same is: 90 + 9*(area of carpet) = 50 + 13*(area of carpet)

The area of carpet for which the cost is the same is: 10 square yard

Step-by-step explanation:

6a) The cost for magic carpet:

This company charges a fixed fee and a price for each square yard of carpeting, therfore the expression for the cost is:

cost = 90 + 9*a

Where a is the area of carpet to be installed.

6)b) The cost for Capeteria:

This company also charges a fixed fee and a price for each square yard of carpeting, so the expression is:

cost = 50 + 13*a.

6) c) The algebraic expression for the cost to be the same in both stores:

90 + 9*a = 50 + 13*a

6) d) We need to solve the expression above for a:

50 + 13*a = 90 + 9*a

13*a - 9*a = 90 - 50

4*a = 40

a = 40/4 = 10

Answer:

t = 7.54 seconds

Step-by-step explanation:

The distance h(t) in feet traveled by a freely falling object is given by the function :

[tex]h(t)=16t^2[/tex]

The height of a tower is 912 feet.

It is required to find the time it will taken to fall on ground from the top of the building. It can be calculated as :

[tex]16t^2=912\\\\t=\sqrt{\dfrac{912}{16}}\\\\t=7.54\ s[/tex]

So it will taken 7.54 seconds to fall on the ground.

Answer:

0 < x < 50

Step-by-step explanation:

We start out with a square (which IS a rhombus for all sides are equal in

length. That's when the diagonals are equal in length, which, by the

Pythagorean theorem equal to

5*√2

C^2=a^2+b^2

=25^2+25^2

Factorise

c^2=25^2 × 2

c=square root of 25^2 × 2

That is

c=√25^2 × 2

=5×√2

As we decrease the angle on the bottom left and increase the angle on

the bottom right, the green diagonal increases to 25+25 or 50, but never gets to 50. The red diagonal shrinks to 0 but never gets to 0.

the lengths of a diagonal can only be in the open interval from 0 to 50. In interval notation that is (0,50) or 0 < x < 50.

Answer:

Minimum value: 0, Maximum value: 50

Step-by-step explanation:

A rhombus is a quadrilateral with side of same length but different angle pairs. Let consider the following rhombus (See attachment). It is known that sum of all angles in quadrilateral is equal to 360°. The length of each diagonal is, respectively:

[tex]d_{1} = 2\cdot l\cdot \sin 0.5\alpha[/tex]

[tex]d_{2} = 2\cdot l \cdot \sin (90-0.5\alpha)[/tex]

[tex]d_{2} = 2\cdot l \cdot (\sin 90^{\circ}\cdot \cos 0.5\alpha - \cos 90 \cdot \sin 0.5\alpha)[/tex]

[tex]d_{2} = 2\cdot l \cdot \cos 0.5\alpha[/tex]

Each expression shows that value of a diagonal changes at the expense of the other one inasmuch angle changes. The minimum and maximum values of any of the diagonal occur when trigonometric functions are equal to 0 and 1, respectively.

Minimum value: [tex]d_{min} = 0[/tex], Maximum value: [tex]d_{max} = 2\cdot l = 2 \cdot (25) = 50[/tex]

Answer:

Think about a dice. When a dice is rolled there are 6 possible outcomes: 1, 2, 3, 4, 5 and 6. To find the probability of the event of rolling a 4, find the number of possible ways of rolling a 4 and divide it by the total number of possible outcomes.

There is one way of rolling a 4 and there are six possible outcomes, so the probability of rolling a 4 on a dice is . This is called the ‘theoretical probability’ - in theory, if you roll a dice six times then you should roll a 4 once.

Answer:

[tex]-\dfrac{1}{4}[/tex]

Step-by-step explanation:

Given two points (-9,-6) and (3,-9). The slope of the line through the points is determined by the formula:

[tex]Slope, m=\dfrac{y_2-y_1}{x_2-x_1} ,$ where (x_1,y_1)=(-9,-6), (x_2,y_2)=(3,-9)\\$Therefore:\\ m=\dfrac{-9-(-6)}{3-(-9)}\\=\dfrac{-9+6}{3+9}\\=\dfrac{-3}{12}\\\\m=-\dfrac{1}{4}\\[/tex]

The slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]

Answer:

the slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]

Step-by-step explanation:

Given that,

Points (x₁ , y₁) is (-9,-6) respectively and

( x₂ , y₂) is (3,-9) respectively.

The slope of the line through the points is determined by the formula:

[tex]Slope, m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

where x₁ = -9

y₁ = -6

x₂ = 3

y₂ = -9

Therefore:

[tex]\\ m=\dfrac{-9-(-6)}{3-(-9)}\\=\dfrac{-9+6}{3+9}\\=\dfrac{-3}{12}\\\\m=-\dfrac{1}{4}\\[/tex]

Therefore, the slope of the line through the points (-9,-6) and (3,-9) is [tex]-\dfrac{1}{4}[/tex]

Answer:

cosθ= [tex] \frac{ \sqrt{15} }{8} [/tex]

Step-by-step explanation:

Please see attached picture for full solution.

In the 4th quadrant, the cosine of an angle is positive.

The opposite side takes the negative sign in -⅞ since it is below the x-axis. Likewise, we reject [tex]x = - \sqrt{15} [/tex] since x lies on the right side of the y axis.
