Carlita has a swimming pool in her backyard that is rectangular with a length of 26 feet and a width of 14 feet. She wants to install a concrete walkway of width c around the pool. Surrounding the walkway, she wants to have a wood deck that extends w feet on all sides. Find an expression for the perimeter of the wood deck.

Answers

Lets solve the question,

Given dimensions are:

Length = 26 feet

Width = 14 feet

concrete walkway with width = c

After installing the concrete walkway dimensions of the walkway will be,

Length = 26 + 2c

Width = 14 + 2c

She wants to build a wooden deck around the pool with a concrete walkway of width = w

Thus the dimensions of the wooden deck around the pool will be,

Length = [tex]26 + 2c + 2w[/tex]

Width = [tex]14 + 2c + 2w[/tex]

Now the perimeter of the wooden deck will be,

Perimeter = 2(length + width)

 [tex]= 2[(26 +2c + 2w) + 2(14 + 2c + 2w)] = 2(40 + 4c + 4w) = (80 + 8c + 8w)[/tex]

Therefore, perimeter of the wooden deck would be: 80 + 8c + 8w

Perimeter = (80 + 8c + 8w)

What is an Arithmetic Sequence ?

An arithmetic sequence is a series of terms which have  common difference between its consecutive numbers.

The sequence given is

−7, −4, −1, 2, 5, …

The common difference between each term is d =3

-4-(-7) = 3

-1-(-4) =3

The nth term for a sequence is given by

[tex]\rm T_n = a +(n-1)d[/tex]

Here a is the first term = -7

n is the no. of terms  = n

d is the common difference = 3

Therefore the equation will be

[tex]\rm T _n = -7 + (n-1) * 3[/tex]

[tex]\rm T _n[/tex] = -7 +3n -3

[tex]\rm T _n[/tex] = 3n -10

Given that the sum to infinity of a G.P. is 10. If the first term of the series is given as 5, determine the 3rd term.

Answers

Answer:

a₃ = 1.25

Step-by-step explanation:

the sum to infinity is calculated as

S ∞ = [tex]\frac{a_{1} }{1-r}[/tex]

a₁ is the first term and r the common ratio

given a₁ = 5 and S∞ = 10 , then

10 = [tex]\frac{5}{1-r}[/tex] ( multiply both sides by (1 - r)

10(1 - r) = 5

10 - 10r = 5 ( subtract 10 from both sides )

- 10r = - 5 ( divide both sides by - 10 )

r = 0.5

then

a₂ = a₁ × r = 5 × 0.5 = 2.5

a₃ = a₂ × r = 2.5 × 0.5 = 1.25

What is the chance of landing on $500 and then Lose A Turn?

Answers

Answer:

B = an event that in the second turn it will land on Lose a Turn. Based from the given wheel, there are 24 equal parts with three $500 and one Lose a Turn. Thus, the probability of landing on $500 then lose a turn is 1921 .

this is possible IF thewheele consists of 24 parts

The chance of landing on $500 and then Lose A Turn will be 1/192. Then the correct option is C.

What is probability?

Its basic premise is that something will almost certainly happen. The percentage of favorable events to the total number of occurrences.

The diagram is given below.

The total number of the events will be

Total events = 24

Then the chance of landing on $500 will be

The number of favorable events will be

Favorable events = 3

⇒ 3/24

⇒ 1/8

Then the chance of the Lose A Turn will be

Favorable event = 1

⇒ 1/24

The chance of landing on $500 and then Lose A Turn will be

P = (1/24)(1/8)

P = 1/192

The chance of landing on $500 and then Lose A Turn will be 1/192.

Then the correct option is C.

Answers

A ratio shows us the number of times a number contains another number. The length of the pieces of wire are 200m, 250m, 300m, 350m, and 400m.

What is a Ratio?

A ratio shows us the number of times a number contains another number.

Given the piece of wire are in the ratio 4:5:6:7:8. Therefore, the total length of the wire will be,

4x + 5x + 6x + 7x + 8x = 1500m

30x = 1500 m

x = 50 m

Now, the length of the wire will be,

4x = 4(50) = 200m

5x = 5(50) = 250m

6x = 6(50) = 300m

7x = 7(50) = 350 m

8x = 8(50) = 400 m

Hence, the length of the pieces of wire is 200m, 250m, 300m, 350m, and 400m.

The height of the balloon (n +1) minutes after it starts to descend, hn + 1 metres, is given by
hn + 1 = K×hn
+ 20 where K is a constant.
The balloon starts to descend from a height of 1200 metres at 09 15
At 09 16 the height of the balloon is 1040 metres.
Work out the height of the balloon at 09 18

Answers

Answer:

The height of the balloon at 09 18 =  788.4 meters.

Step-by-step explanation:

As the hot air balloon is descending.

and the height of the balloon n minutes after it starts to descend is [tex]h_{n}[/tex]

meters.

The height of the balloon (n +1) minutes after it starts to descend, [tex]h_{n+1}[/tex]meters, is given by

[tex]h_{n+1}[/tex]= [tex]k *h_{n}+20\\[/tex] where K is a constant

Here the balloon starts to descend from a height of 1200 meters at 09 15

So [tex]h_{n}[/tex]=1200 meters

At 09 16 the height of the balloon is 1040 meters.

So  [tex]h_{n+1}[/tex]= 1040 meters

the height of the balloon at 09 18 = [tex]h_{n+3}[/tex] meters

now  [tex]h_{n+1}[/tex]= [tex]k *h_{n}+20\\[/tex]

k = [tex]\frac{h_{n+1 }-20 }{h_{n} }[/tex]

k= (1040 - 20) ÷ 1200

k = 0.85

Now [tex]h_{n+2}[/tex] = (0.85 × 1040) +20 =904 meters

Similarly  [tex]h_{n+3}[/tex] = (0.85 × 904) +20 = 788.4 meters.

Therefore the height of the balloon at 09 18 =  788.4 meters.

The reason I multiplied 3 to the second equation is for when we add the equations together the x will cancel out.

  -3x-4y=20

+  3x-30y=48

  -34y=68

Divide -34 from both sides.

y=-2

To find x you need to plug in -2 for y into one of the equations.

Given two terms in a geometric sequence find the first five terms.
6) a5 = -162 and a2=-6

Help please!!!

Answers

The first five terms of the geometric series is : -2, -6, -18, -54, -162.

To solve the given problem :

Given :  [tex]a_{5} = -162[/tex]

[tex]a_{2} = -6[/tex]

We know G.P. series always increases in the form [tex]a.r^{n-1}[/tex]

Similarly, [tex]a_{5} = a.r^{5-1} = a.r^{4} = -162[/tex]

[tex]a_{2} = a.r^{2-1} = a.r = -6[/tex]

Now, [tex]\frac{a_{5} }{a_{2} } = \frac{a.r^{4} }{a.r^{1} } = r^{4-1}[/tex]

[tex]r^{3} = \frac{-162}{-6} = 27[/tex]

[tex]r = \sqrt[3]{27} = 3[/tex]

Now,

[tex]a_{2} = a.r = -6\\a.(3) = -6\\a = -2[/tex]

The first 5 terms are  :  [tex]a, a.r, a.r^{2} , a.r^{3} , a.r^{4}[/tex]

[tex]-2 , (-2).3 , (-2).3^{2} , (-2).3^{3} , (-2).3^{4}[/tex]

The given is a right triangle, in right triangles the sum of square value of two legs (base and height) is equal to square value of hypotenuse.

Now, know the value of base and hypotenuse are 24  and 26

let x represent the missing side:

The length of D G is 15, the length of G F is 5, the length of E H is 12, and the length of D E is 8.To prove that DFE ~ GFH by the SSS similarity theorem using the information provided in the diagram, it would be enough additional information to know that Using the conclusion from ruthefords model, identify a charged subatomic particle that is located in the nucleus What do we call risks in the absence of controls and after controls have been implemented?. Insert a digit in each place "..." to make numbers that are divisible by 6if it is possible:4...9 Square root of (-16)^2 (5x-1) -(2-8x) for x = 0.75 Question 4 (Essay Worth 10 points)(05.06; 05.07 MC)A prism and two nets are shown below:Image of a right triangular prism and 2 nets. The triangle bases have base 4, height 3, and diagonal side 5. The length of the prism from the bases is 8.6. Net A has 3 rectangles in a row. The middle one has sides AC and CD. This middle one has triangle ABC on top and identical triangle below. Net B is the same except that the triangle base ABC is on top of the last rectangle which has sides AC and CD. Units are in inches.Part A: Which is the correct net for the prism? Explain your answer. (2 points)Part B: Write the measurements of Sides AB, BC, and CD of the correct net.
