Step-by-step explanation:

Answer:

8 b mod 12 is equal to 4.

Step-by-step explanation:

Use Dividend = Divisor × Quotient + Remainder

As b mod 12 = 5 (that is division of b by 12 gives a remainder of 5)

[tex]b=12k+5[/tex]

Here, k is any integer.

Multiply both sides of [tex]b=12k+5[/tex] by 8

[tex]8b=8(12k+5)\\8b=8(12k)+40[/tex]

write 40 in terms of 12

[tex]40=36+4=12(3)+4[/tex]

[tex]8b=8(12k)+12(3)+4\\8b=12(8k+3)+4[/tex]

Therefore,

8 b mod 12 is equal to 4.

Answer:

$31.50

Step-by-step explanation:

To solve this problem, create the equation

y = 0.10x + 25

Where x is equal to the number of international minutes and y is equaled to the total price paid. Since we are give the number of international minutes (the x), plug this into the equation and solve for y.

y = 0.10(65) + 25

y = 6.5 + 25

y = 31.5 or $31.50

D. -i

Step-by-step explanation:

I took the quiz and got a 100%

The required value of the complex number [tex]i^{31}[/tex] = -i.

Given that,
To determine the value of complex numbers [tex]i^{31}[/tex].

In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,

The number that are constitute of real and imaginary numbers are called complex number. complex number can be represents as z = a+ ib ,where a = real part and bi = imaginary part.

Here,
[tex]i^4 = 1[/tex] and [tex]i^3 = -i[/tex]

For complex numbers [tex]i^{31}[/tex]

[tex]=i^{31}\\=(i^4)^7.i^3\\=1.-i\\=-i[/tex]

Thus, the required value of the complex number [tex]i^{31}[/tex] = -i.

Answer:

B). x=9

Step-by-step explanation:

4 x (5 + 4) =3 ×(x + 3)

36=3x+9

3x=27

x=9

Answer:

8000309

Step-by-step explanation:

x=45, we know 2x is 90 because it is a right angle, so we can divide 90 by two, to get 45. Now to substitute, 90+55+(45-10) = 180, therefore, this answer would make logical sense.

Answer:

answer is 108

Step-by-step explanation:

You would divide 28 by 7 which is 4 so the bigger triangle is 4 times the size of the smaller rectangle. in order to find the perimeter you would multiply each side of the smaller triangle by 4 and add up all the sums. except the one you were given so 28+(12times4)+(8times 4)+108

Answer:

x = 2

Step-by-step explanation:

Vertical angles are equal to each other. It means that,

∠A = ∠B

So,

20x+10 = 30x−10

Taking like terms together, we get :

20x-30x=-10-10

-10x=-20

x=2

So, the value of x is 2.
