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

Answer:

C.) y = 9

Step-by-step explanation:

Simply substitute in -2 for x.

y = -4(-2) + 1

y = 8 + 1

y = 9

Answer:

5

Step-by-step explanation:

80 is at the top and 40 takes half of the bottom so the other half is 40.

15/120 = 0.125 so...

40x0.125 will be your answer.

You get 5.

Answer:

quite not sure

Step-by-step explanation:

Answer:

it would be 3.0 times 0.03 so the answer is 0.9

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:

8/15

Step-by-step explanation:

(2/5)/(3/4)

2*4=8

5*3=15

8/15

Answer:

[tex]\frac{8}{15}[/tex]

Step-by-step explanation:

[tex]\frac{2}{5}[/tex] ÷ [tex]\frac{3}{4}[/tex]    (convert division to multiplication by inverting the second fraction)

= [tex]\frac{2}{5}[/tex] × [tex]\frac{4}{3}[/tex]   (combine fractions by multiplying numerator with numerator and denominator by denominator)

= [tex]\frac{(2)(4)}{(5)(3)}[/tex]

= [tex]\frac{8}{15}[/tex]

Answer:

B). x=9

Step-by-step explanation:

4 x (5 + 4) =3 ×(x + 3)

36=3x+9

3x=27

x=9

Answer:

[tex]\huge\boxed{7^{x-y}}[/tex]

Step-by-step explanation:

We can use basic exponent rules to simplify this expression.

We know that [tex]a^b \div a^c = a^{b-c}[/tex].

Since we have the same base (7) and different exponents (x, y), we can subtract the exponents and raise the base to that power.

[tex]7^{x-y}[/tex]

Answer:

D

Step-by-step explanation:

It is x<2 which means x can not be 2, so it is a dotted line, then x is anything less than 2, so it is shaded to the left.

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.

Answer:

T = 38

Step-by-step explanation:

T = 38 because:

1) Plug in all the variables into the equation

Equation: T = 62 - 4(6)

2) Next, solve the equation. First, do multiplication because of order of operations.

Equation: T = 62 - 24

3) Now just subtract 62 and 24

Equation: 38 = 62 - 24

Therefore, T = 38

y = -8

Answer:

option #2

Step-by-step explanation:

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

hope this helps you out :)

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:

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.

The number of turns completed in 1 week is 10.5.

Given that,

Based on the above information, the calculation is as follows:

As we know that in one week there are 7 days, so the no of turns in one week is

[tex]= 1.5 \times 7[/tex]

= 10.5

Therefore we can conclude that the number of turns completed in 1 week is 10.5.
