Answer:

V = 3.

Step-by-step explanation:

(I'll try.)

v/9 = 4/12

you cancel the common factor which is four.

next, you multiple both sides by nine, which make:

9v

_ = 1 , 9

_____

and I guess you simplify it, and then it becomes V = 3.

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

       s - 68

        c + 27

Hence:

c + 27 = 6 (s - 68)

c + 27 = 6s - 408

        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:

Option C.

Step-by-step explanation:

Notice that only option B and C involves the vectors in transformation

[tex]A=\begin{bmatrix}4\\2\end{bmatrix}, B=\begin{bmatrix}-8\\-4\end{bmatrix}[/tex]

However, option B is not a defined multification since the dimension of both matrices are not matching. Vector A is 2x1 but the second matrix is 2x2.

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

Explanation:

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

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,

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)}.

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.

Step-by-step explanation:

one x equal to 20 degree

and if 3x= 60 degree the ? = 120 degree

Answer:

∠ ABF = 120°

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°

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.

Answer:

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.

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]
