[tex]\fbox{\fbox{Circumference = 226.08 feet}}[/tex]

Step-by-step explanation:

Given:

distance from center to the edge(Radius) of playground = 36 feet

To find:

Circumference of playground=?

Solution:

we know that,

Circumference of circle = 2πr

substituting the radius value in above formula,

[tex]2 \pi r = 2 \times 3.14 \times 36 = 226.08 \: ft[/tex]

[tex]\fbox{\fbox{Circumference = 226.08 feet}}[/tex]

Thanks for joining brainly community!

Answer: 226.08ft

Step-by-step explanation: we are finding the circumference of a circle so we will make 3.14 times 2 times 36 as it is a radius I think .

3.14 ×2×36=226.08 and the units is feet . Hope it helps buddy

Since, there are 36 inches in 1 yard, multiply 3 1/3 by 36

So, 3 1/3 yards = 120 inches

Answer:

120 inches

Step-by-step explanation:

To convert 3 1/3 yards to inches, you first need to figure out how many inches are in one yard. 1 yard=36 inches.

After this, you would turn your mixed fraction into an improper fraction and then multiply by 36 inches. It would look like this:

10/3 * 36/1

Here, you would cancel out the common factors by factoring 36 by 3.

12*3=36 ----> 10/3 * [tex]\frac{3(12)}{1}[/tex] ----->

Lastly, multiply 10 by 12 and your answer would be 120 inches.

Answer:

the answer in the question mark that was in the green box ???

Answer:

6.856

Step-by-step explanation:

8² + x² = 17

8² - 17 = -x²

64 - 17 = -x²

-47 = -x²

x² = 47

x = 6.856

missing angle:

180° - 90° - 30°

180° - 120°

60°

missing sides:

(a)

[tex]\rightarrow \sf tan(x)= \dfrac{opposite}{adjacent}[/tex]

[tex]\rightarrow \sf tan(30)= \dfrac{4}{adjacent}[/tex]

[tex]\rightarrow \sf adjacent= \dfrac{4}{tan(30)}[/tex]

[tex]\rightarrow \sf adjacent= 4\sqrt{3}[/tex]

[tex]\rightarrow \sf adjacent= 6.93 \ cm[/tex]

(b)

[tex]\sf \rightarrow sin(x)= \dfrac{opposite}{hypotensue}[/tex]

[tex]\sf \rightarrow sin(30)= \dfrac{4}{hypotensue}[/tex]

[tex]\sf \rightarrow hypotensue= \dfrac{4}{ sin(30)}[/tex]

[tex]\sf \rightarrow hypotensue= 8 \ cm[/tex]

Answer:

m∠X = 60°

BX = 8 cm

BM = 4√3 cm

Step-by-step explanation:

The sum of the interior angles of a triangle is 180°

Given:

⇒ m∠B + m∠M + m∠X = 180°

⇒ 30° + 90° + m∠X = 180°

⇒ 120° + m∠X = 180°

⇒  m∠X = 180° - 120°

⇒  m∠X = 60°

Using the sine rule to find the side lengths:

[tex]\dfrac{a}{\sin A}=\dfrac{b}{\sin B}=\dfrac{c}{\sin C}[/tex]

(where A, B and C are the angles, and a, b and c are the sides opposites the angles)

Given:

[tex]\implies \dfrac{4}{\sin 30\textdegree}=\dfrac{BX}{\sin 90\textdegree}=\dfrac{BM}{\sin 60\textdegree}[/tex]

[tex]\implies BX=\sin 90\textdegree \cdot\dfrac{4}{\sin 30\textdegree}[/tex]

              [tex]=1 \cdot \dfrac{4}{\frac12}[/tex]

              [tex]=1 \cdot 4 \cdot 2[/tex]

              [tex]=8 \textsf{ cm}[/tex]

[tex]\implies BM=\sin 60\textdegree \cdot\dfrac{4}{\sin 30\textdegree}[/tex]

              [tex]=\dfrac{\sqrt{3}}{2}\cdot \dfrac{4}{\frac12}[/tex]

              [tex]=\dfrac{\sqrt{3}}{2}\cdot 4 \cdot 2[/tex]

              [tex]=4\sqrt{3} \textsf{ cm}[/tex]

Answer:

18 freshmen, 18 sophomores, 30 juniors, 30 seniors

Step-by-step explanation:

Given ratio

  freshman : sophomores : juniors : seniors

= 320 : 300 : 500 : 510

320 ≈ 300  and  500 ≈ 510

Therefore, 300 : 300 : 500 : 500

Ratio of 300 : 500 = 18 : 30

So  18 : 18 : 30 : 30 best represents the population

Given nos

Ratio:-

Round out

Option A

Lets have Anisah be x right now.

4 years ago, Adrian was (x-4) + 28 = x+24
Right now, Adrian is 3x.

Knowing those two pieces of information, we can say that x+24 is equal to 3x-4. (This is because Adrian is 3x right now, and for 4 years ago, you subtract 4.)

x+24=3x-4
24=2x-4
28=2x
x=14

Right now Anisah is 14, and in 4 years he will be 14+4 = 18.

Answer:

5/9

Step-by-step explanation:

Let the probability of getting a multiple of 3 is "A"

Let the probability of getting an even number is "B"

Total number of outcomes=36

Total number of favourable outcomes of either a multiple of 3 or an even number are

(1,1) ,(1,2) ,(2,1) ,(1,3) ,(3,1) ,(2,2) ,(1,5) (5,1) ,(3,3) ,(2,4) ,(4,2) ,(2,6) ,(6,2) ,(3,5) ,(5,3) ,(4,4) ,(6,4) ,(4,6) ,(5,5) ,(6,6)

That is we have 20 favourable outcomes

Hence, Probability=\frac{\text{favourable outcomes}}{\text{total number of outcomes}}Probability=

total number of outcomes

favourable outcomes

Therefore, after substituting the values we get

probability=\frac{20}{36}probability=

36

20

After simplification we will get

probability=\frac{5}{9}probability=

Answer:

Price of an adult ticket: 12$

Price of a student ticket: 8$

Step-by-step explanation:

Let x be the price of an adult ticket, and y be the price of a student ticket.

We have the equation:

2x + 5y = 64

3x + 4y = 68

=> x - y = 4

2x + 5y = 64

=> x = 4+y

2*(4+y) + 5y = 64

=> x = 4+y

8 + 2y + 5y = 64

=> x = 4 + y

7y = 56

=> x = 4 + y

y = 8

=> x = 12

y = 8

  cost = 33

Step-by-step explanation:

Kruskal's Algorithm is a "greedy" algorithm that adds the next minimum-weight edge to the tree, provided that it does not create a loop.

__

The minimum-weight edge in the graph is DF, with weight 1.

The next minimum-weight edge is GH, with weight 2.

The next minimum-weight edge is AB, with weight 3.

The next minimum-weight edge is EF, with weight 4.

Edge DE is the next lowest-weight, but it creates a loop (DEF), so we ignore it.

BC is the next edge we'll add to our tree.

FG is the next edge we'll add to the tree.

Edge DG creates a loop, so we ignore it.

Edge FH creates a loop, so we ignore it.

CF is the next edge we'll add to the tree. This completes the minimum spanning tree using Kruskal's Algorithm.

Included edges are AB, BC, CF, DF, EF, GF, GH.

The cost of the tree is 3+6+10+1+4+7+2 = 33.

square two sides

x+8=(x+8)2

x+8=x2+16x+64

x2+16x+64-x-8=0

x2+15x+56

Answer:

2.75

Step-by-step explanation:

When x = 4, y = 11

when x = 1, y = 2.75

k = 2.75

Part a)

The home value is $120,000 and they get a loan for $90,000.

This must mean the down payment was 120,000 - 90,000 = 30,000 dollars. This is the payment made up front.

The mortgage has a monthly payment of $786.60 which is done for 25 years = 25*12 = 300 months. They pay back 786*300 = 235,800 dollars.

Therefore, the total amount they pay for the house is:

downPayment + loanRepayment = 30,000 + 235,800 = 265,800

=======================================================

Part b)

Refer to the previous part. Laura and Martin pay back $235,800 after being loaned $90,000

The total amount of interest is 235,800 - 90,000 = 145,800 dollars.

=======================================================

Part c)

The annual interest rate is 9.5% which converts to the decimal form 0.095

Divide this over 12 to get the monthly interest rate in decimal form.

0.095/12 = 0.00791667 approximately

Then multiply this with the initial balance of $90,000

90,000*0.00791667 = 712.5003

This rounds to 712.50 and this represents the interest for the first month.

This leads to:

principal = monthlyPayment  - interest

principal = 786.60 - 712.50

principal = 74.10

It is unfortunately common practice that the starting monthly payments will be mostly interest. As time goes on, the increase payments decrease because they are tied directly to the remaining balance.

Answer:

∠s = ∠v

Step-by-step explanation:

Supplementary angles add up to 180°

∠s + ∠v = 180

90 + ∠v = 180

     ∠v = 180 - 90

      ∠v = 90°

⇒∠s ≅ ∠v
