Evaluate the number sequence. What number should come next in this following sequence? 6, 2, 12, 4, 24 =

Answers

Answer:  Either 6 or 8

Explanation:

Notice that the first, third and fifth values are: 6,12,24. It appears the pattern here is "times 2". So we double each value to get the next item. This only seems to apply for the odd numbered slots.

For the even number slots, we have the pattern: 2,4. The next item isn't clear. We could do two things

add 2multiply by 2

If we go with the first option, then we have 4+2 = 6 as the next term

OR

If we go with the second option, then we have 4*2 = 8 as the next term

Unfortunately, there isn't enough information to know which would actually be the next term. A common problem with sequence problems like this is that there are often many ways to generate the same subsequence, which leads to ambiguity as to what the next term would be.

Sam baked an equal number of sausage buns and
custard buns. During the day, 68 sausage buns were
sold. Sam also baked another 27 custard buns to meet a last-minute
order. At the end of the day, Sam had baked 6 times as many custard
buns as the number of sausage buns remaining. How many sausage
buns did Sam bake at first?

Answers

Answer:

87

Step-by-step explanation:

number of sausage buns = s

number of custard buns = c

at the start of the day, s = c

at the end of the day

c+27=6(s-68)

since c = s,

s+27=6(s-68)

s+27=6s-408

-5s = -435

s=87

Let us represent:

The number of sausages baked at first =  s

The number of custard buns baked at first =  c

During the day, 68 sausage buns were  sold. This can be expressed using algebraic equations as:

       s - 68

Sam also baked another 27 custard buns to meet a last-minute  order. This can be expressed using algebra as:

        c + 27

At the end of the day, Sam had baked 6 times as many custard  buns as the number of sausage buns remaining.

Hence:

c + 27 = 6 (s - 68)

c + 27 = 6s - 408

Note: Sam baked an equal number of sausage buns and custard buns. This means:

        c = s

Hence,

c + 27 = 6s - 408

s + 27 = 6s - 408

Collect like terms

408 + 27 = 6s - s

435 = 5s

Divide both sides by 5

435/5 = 5s/5

s = 87

Therefore, the number of sausage buns Sam baked at first is 87 sausage buns.

Answer:

1) The polar form of that equation will be r= √5cos(2θ)

2) i am stuck on this one (sorry)

Step-by-step explanation:

(i) We know that [tex]x = r\cos{\theta}\:\text{and}\:y = r\sin{\theta}.[/tex] So we can write the given equation as

[tex]r^2\cos^2\theta - r^2\sin^2\theta = 5[/tex]

[tex]\Rightarrow r^2(\cos^2\theta - \sin^2\theta) = 5[/tex]

[tex]r^2 = \dfrac{5}{(\cos^2\theta - \sin^2\theta)}[/tex]

[tex]\:\:\:\:\:=\dfrac{5}{\cos{2\theta}} = 5\sec{2\theta}[/tex]

(ii) Recall that

[tex]\cot{\theta} = \dfrac{\cos{\theta}}{\sin{\theta}}[/tex]

[tex]\csc{\theta} = \dfrac{1}{\sin{\theta}}[/tex]

so we can write r as

[tex]r = 8\cot{\theta}\csc{\theta}[/tex]

[tex]\:\:\:\:= 8\left(\dfrac{\cos{\theta}}{\sin{\theta}}\right)\left(\dfrac{1}{\sin{\theta}}\right)[/tex]

[tex]\:\:\:\:= 8\left(\dfrac{x}{y}\right)\!\left(\dfrac{r}{y}\right) = \dfrac{8xr}{y^2}[/tex]

Upon simplification, we get

[tex]y^2 = 8x[/tex]

you are given numbers, {30 + n, n/3, square root n+16}. Find the smallest value of n so that all of the numbers in the set are natural numbers.

Answers

Answer:   n = 9

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

Explanation:

Let's assume that n is not negative. If we tried the smallest nonnegative value, n = 0, then we get

30+n = 30+0 = 30n/3 = 0/3 = 0sqrt(n+16) = sqrt(0+16) = 4

The middle result 0 isn't a natural number. The set of natural numbers is {1,2,3,4,...} which is the set of positive whole numbers.

So we can't use n = 0.

Through trial and error, you should find that n = 9 is the next value we can try such that sqrt(n+16) is a natural number, and so is n/3.

If n = 9, then,

30+n = 30+9 = 39n/3 = 9/3 = 3sqrt(n+16) = sqrt(9+16) = 5

We see that the middle result is now larger than 0 and it's a natural number. The same can be said for the last result as well.

The smallest value of n = 9 is that all of the numbers in the set are natural numbers in {30 + n, n/3, √(n+16)}.

What are Natural Numbers?

Natural numbers are defined as which range from 1 to infinity, are the most fundamental sort of numbers. Commonly known as positive numbers or counting numbers, these numbers. Natural Numbers are represented by the symbol N.

Assume n is not negative for the whole number. Using n = 0, the smallest nonnegative value, we obtain

30 + n = 30 + 0 = 30

n/3 = 0/3 = 0

√(n+16) = √(0+16) = 4

In the middle result, 0, there is no natural number. The set of positive whole numbers starting with {1, 2, 3, 4, ..} is known as the natural numbers.

Therefore, n = 0 is not a possibility.

We have to determine by trial and error that n = 9 is the next possible value we may test such that √(n+16) is a natural number and so is n/3.

If n = 9, then,

30 + n = 30 + 9 = 39

n/3 = 9/3 = 3

√(n+16) = √(9+16) = 5

The middle result, which is now greater than 0, is a natural number, as can be shown. The final outcome also corresponds to this description.

Thus, the smallest value of n = 9 is that all of the numbers in the set are natural numbers.

Kelsey deposited $3,600 in a bank account with annual interest rate 4.25%. How much interest was earned in 5 years?

Answers

Answer:

in 1year =4.25%in 5year=xthen 1=4.25%5=x then cross x=4.25%*5=21.25%

Answer:

$765

Step-by-step explanation:

If an amount of money, P, called the principal, is invested for a period of t years at an annual interest rate r, the amount of interest, I, earned is given by

I =Prt           where

I =interest

P =principal

r =rate

t =time

The following information is given.

Prt=$3,600=4.25%=5 years

Substituting the given information into the simple interest formula and solving for I gives

I =Prt

I =(3,600)(0.0425)(5)

=765

The amount of interest Kelsey earned in 5 years was $765.

Step-by-step explanation:

HCI is a straight line , so

3x + 2x + 4x = 180 , that is

9x = 180 ( divide both sides by 9 )

x = 20

∠ ABF and ∠ BCI are corresponding angles and are congruent , so

∠ ABF = 2x + 4x = 6x = 6(20) = 120°

A small publishing company is planning to publish a new book. The production costs will include one-time fixed costs (such as editing) and variable costs (such
as p rinting). There are two production methods it could use. With one method, the one-time fixed costs will total $16,465, and the variable costs will be $20.50
per book. With the other method, the one-time fixed costs will total $37.815, and the variable costs will be $11.75 per book. For how many books produced will
the costs from the two methods be the same?

Answers

9514 1404 393

Answer:

   2440

Step-by-step explanation:

The difference in fixed costs is ...

  37815 -16465 = 21350

The difference in variable costs is ...

  20.50 -11.75 = 8.75 . . . . per book

Then the number of books that must be produced for the difference in variable costs to be equal to the difference in fixed costs is ...

  21350/8.75 = 2440

For production of 2440 books, the costs of the two methods will be the same.

Additional comment

You can write expressions for total cost of each production method. When you set them equal and solve for the number of books, you find the math you end up doing is the same as that shown above.
