A circular flower bed is 21 m in diameter and has a circular sidewalk around it that is 4 m wide. Find
the area of the sidewalk in square meters. Use 3.14 for Pi
The area of the sidewalk is ____ m2.

Answer:

The pair of shoes cost $33.50

Step-by-step explanation:

let the cost of dresses be d and the cost of shoes be s

2 dresses and 1 shoe pair cost $70.5

2d + s = 70.5 •••••(i)

Shows cost $15 more than one dress

s = d + 15

d = s-15 ••••(ii)

Substitute ii into i

2(s-15) + s = 70.5

2s -30 + s = 70.5

3s = 70.5 + 30

3s = 100.5

s = 100.5/3

s = $33.50

Answer:

True

Step-by-step explanation:

2x + 14y - y  = 2x + 13y

Have a good day :)

Answer:

true

Step-by-step explanation:

Distribute the 2 to the x and 7y. your equation will nob be 2x+14y-y=2x+13. so combine the like terms, 14y and -y, so you get 13y. you now have 2x+13y=2x+13y. which is true

Consequently, this student's quiz results have a median, or "middle," value of 16.

When a dataset is ordered, the median value is the one that appears exactly in the middle of the dataset. The difference between the lowest and highest 50% of data is a measure of central tendency or average. Depending on whether you have an odd or even number of data points, the procedures for determining the median , mode change.

Here,

the median, or "middle" value in a data set. Your data must be in numerical order in order to calculate the median.

Exam results:

9, 13, 20, 15, 18, 17

Number the rows and columns.

9, 13, 15, 17, 18, 20

Calculate the "middle" value:

9, 13, 15, 17, 18, 20

If there are two middle values, put them together and divide by two.

15 + 17 = 32

32/2 = 16

Consequently, this student's quiz results have a median, or "middle," value of 16.

On solving the provided question, we can say that by permutation If an ID card has six digits and each digit may only be used once, then 151,200 distinct ID cards can be created.

The permutation of a set in mathematics is essentially the rearranging of its elements if the set is already ordered, or the arrangement of its members in a linear or sequential order. The act of altering the linear order of an ordered set is referred to as a "permutation" in this context. The mathematical calculation of the number of possible arrangements for a given set is known as permutation. Permutation, in its simplest form, refers to the variety of possible arrangements or orders. The placement of the elements matters with permutations. The placement of items in a specific order is known as a permutation. Here, the set's components are sorted in either chronological order or linear order. like in the case of.

There are 6 digits on a card ( 0 - 9 ).

10 * 9 * 8 * 7 * 6 * 5 = 151,200

Therefore, the fraction 5/4 in this equation represents the growth factor of the height of the item over time.

An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a correct fraction is smaller than the denominator.

The total number of equally sized components chosen is shown in the numerator. The denominator, however, shows the total number of equal pieces.

The fraction 5/4 in this equation represents the growth factor of the height of the item over time. The value of 3 in front of the fraction is the initial height and the exponent x represents the number of days that have passed, so the height of the item increases by a factor of 5/4 for every additional day. The height equation represents exponential growth.

Answer:

  3.  B  (1, -7)

  4.  B  x < -4

Step-by-step explanation:

3. An ordered pair is a solution to a set of equations or inequalities when putting the x and y values into each expression makes the expression true.

Here, all of the y-values offered are less than 2, so we need to look at whether the given points satisfy the second inequality.

  A 0 -(-5) > 5   ⇒   5 > 5 . . . FALSE

  B 1 -(-7) > 5   ⇒   8 > 5 . . . True

  C -3 -(-4) > 5   ⇒   1 > 5 . . . FALSE

The point (1, -7) satisfies both inequalities, so is a solution of the system.

__

4. The boundary line of an inequality is solid when the "or equal to" case is included in the solution. The symbols used for that are ≤ or ≥. When the symbol is < or >, the "or equal to" case is not included, and the boundary line is dashed.

Here, you can answer the question based simply on the < symbol. There is only one inequality shown that will have a dashed boundary line: choice B.

__

On a usual graph, x-values increase to the right, and y-values increase in the up direction. This means lesser values of x or y are to the left or down. You can determine the side of a boundary line that is shaded by considering this fact.

All you really need to do is find a variable term with a positive coefficient and look at where it stands in relation to the inequality symbol. Here, we have ...

  x < (something)

This tells us the shading will be where x-values are less than (left of) those on the boundary line.

So, for x < -4, shading will be to the left of the dashed boundary line.

When B is the circumcenter of  triangle ADG the lengths of AE and DG are 4 and 12 respectively

The intersection of the perpendicular bisectors of a triangle's sides is known as the circumcenter of that particular triangle.

In other terms, the circumcenter is the point at which the bisector of a triangle's sides coincides.

The perpendicular lines radiating from the sides of the triangle are the bisectors hence the line it radiates from shares the is shared into two halves at that point

Having this in mind

AE = DE = 4

and

DF = GF = 6

Also, DF + GF = DG

DG = DF + DF

DG = 6 + 6

DG = 12

The plane intercepts on the x,y, z axes are 1, ∞, and 1/2. Hence, the Miller indices for the plane inside the cubic unit cell is (102).

Miller indices are used to specify planes and directions. These planes and directions could be in lattices or crystals. The number of indices will correspond to the size of the lattice or crystal.

In the given graph, the plane intercepts are:

x-intercept : 1

y-intercept : ∞  (since the planes does not intercept y-axes)

z-intercept = 1/2

Take the reciprocal:

1/1 = 1

1/∞ = 0

1/(1/2) = 2
