Answer:

x=97° a=97° b=97°

Step-by-step explanation:

83°+a=180° (by linear pair)

a=180°- 83°

a=97

and a=x°(by corresponding angle)

x= 97°

x=b(by vertical opposite angle)

b = 97°

Answer:

[tex]d=7.8\ g/cm^3[/tex]

Step-by-step explanation:

Given that,

The dimensions of a rectangular block = 4 cm x 2 cm x 1.5 cm

Mass, m = 93.6 g

We need to find the density of steel. We know that the density of an object is equal to the mass divided by volume. So,

[tex]d=\dfrac{m}{V}\\\\d=\dfrac{93.6}{4\times 2\times 1.5}\\\\d=7.8\ g/cm^3[/tex]

So, the density of the steel is [tex]7.8\ g/cm^3[/tex].

Given:

The expression is

[tex]2b+5+1b=3b+5[/tex]

To find:

Whether the two expression in the equation are equal or equivalent.

Solution:

If two expression are exactly the same, then they are equal and if the two expressions are different but the after simplification both are same, then they are called equivalent expressions.

We have,

[tex]2b+5+1b=3b+5[/tex]

Taking LHS, we get

[tex]LHS=2b+5+1b[/tex]

On combining liker terms, we get

[tex]LHS=(2b+1b)+5[/tex]

[tex]LHS=3b+5[/tex]

[tex]LHS=RHS[/tex]

In the given equation both expression are different but after simplification LHS = RHS, therefore the expression are equivalent not equal.

Answer:

C

Step-by-step explanation:

Let's say you wanted to buy a television. The television cost $200 but you only have $100, so you ask your friend for some money. Your friend says they will give you money but you have to pay them back and pay them interest. So when you go pay them, you pay them $100 dollars along with the amount of money your friend wants you to pay them for borrowing their money. In the end you could end up giving them 120 instead of 100.

C. The charge for the privilege of borrowing money

Hope this helps you and you past your test good luck too you.

Answer:

see explanation

Step-by-step explanation:

Under a reflection in the x- axis

a point (x, y ) → (x, - y ). then

G(3, 4 ) → G'(3, - 4 )

Q(4, - 1 ) → Q'(4, 1 )

L(1, 2 ) → L'(1, - 2 )

This is a simple transformation, DILATION.

Upon graphing this out, or finding the side lengths of the triangle, you will find that side length RU is triple of that of RS. This is the same for RV and RT. Dilation transformations don't change angles, only side lengths, and for the whole triangle, which means that this transformation will still equate the triangles to each other.

Answer:

1) 20

2) 4

Step-by-step explanation:

1)

I) Substitute t with 2:

2² + 5(2) + 6

II) Simplify/Evaluate:

2² + 5(2) + 6

4 + 10 + 6

14 + 6

20

2)

I) Setup the equation:

g(t) = 5t - 2 = 18

5t - 2 = 18

II) Solve it:

Reorder the terms:

-2 + 5t = 18

Add 2 to each side of the equation:

-2 + 2 + 5t = 18 + 2

Simplify:

0 + 5t = 18 + 2

5t = 18 + 2

5t = 20

Divide each side by 5:

t = 4

Answer: Option B

Step-by-step explanation:

Answer:

Step-by-step explanation:

In order for Forest to decide how many cans of paint to buy he first needs to know how many square feet make up the wall that he wants to paint. He can calculate this by multiplying the length of the wall by the height of the wall. That will give him the square footage of the wall which can be represented as x in the following formula. Now that he has that, he needs to divide this value by 150 which is what each can of paint covers. The answer will be the number of cans that Forest should buy.

x / 150 = number of cans

The numbers of cans of paint he should buy can be calculated as follows :

x / 150.

where

x = Area of the wall needed to be painted in square feet.

Forest needs to paint the right side of his house because of sunlight and

rain.

According to his analysis each can of paint will cover an area of 150 ft².

This simply means for every 150 square feet of his wall, he will require 1

can of paint.

The number of paint he should buy can be determined as follows:

let

x = area of the right side of his wall needed to be painted

The number of can required = x / 150

Answer: The answer would be D) x²-12

explanation: Values mentioned in the form of table b are not a function. Option D is correct. Given that, Four functions in the tabulated options are given we have to find the one that is not a function. What are functions? Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable. Here, From observation Function mentioned in Tables A, C and D are proper functions because each of them has a relative and corresponding value of ordinate with respect to the abscissa. While in option B one of the abscissae gives two values of the ordinates but another abscissa relates to a single value. That is why Table in B does not represent the functions. Thus, values mentioned in the form of table b is not a function. Option D is correct.

3. not sure

Step-by-step explanation:

5x +2 (x+7) =14x -7

First expand the expandables

5x +2x +14 =14x-7

7x +14 =14x -7

14x -7x =14+7

7x=21 . Divide both sides by 7

x=3.

Step-by-step explanation:

1. 5x +2x + 2*7 =14x-7

7x + 14 = 14x - 7

14 +7 = 14x - 7x

21 = 7x

21/7 =x

9x = $291 - $75

9x = $216

x = $216/9

x = 24

Answer:

La cantidad de dinero adeuda al final de los dos procesos es $1450

Step-by-step explanation:

Los parámetros del proceso son;

La cantidad ahorrada para comprar ropa = $2,000

La cantidad pagada por la ropa = $2600

La cantidad prestada a un amigo = $650

La cantidad adeuda por teléfono celular durante 3 meses = $250

Deje que 'C', represente la suma de las transacciones anteriores, tenemos;

∴ C = 2,000 - 2,600 - 650 - 200 = -1,450

La suma de las transacciones anteriores, C = -$1,450

Por lo tanto, al final de los dos procesos, la cantidad de dinero adeuda es C = $1,450

Answer:

Foci [tex](0,\pm\frac{\sqrt{17}}{4})[/tex]

Vertices:[tex](0,\pm 1)[/tex]

Eccentricity, e=[tex]\frac{\sqrt{17}}{4}[/tex]

Length of latus rectum=[tex]\frac{1}{8}[/tex]

Step-by-step explanation:

We are given that

[tex]y^2-16x^2=1[/tex]

[tex]y^2-\frac{x^2}{(\frac{1}{4})^2}=1[/tex]

The equation of hyperbola is along y-axis because y is positive

Compare the equation with

[tex]y^2/a^2-x^2/b^2=1[/tex] (Along y-axis)

We get

a=1, b=1/4

[tex]a^2+b^2=c^2[/tex]

[tex]1+\frac{1}{16}=c^2[/tex]

[tex]\frac{16+1}{16}=c^2[/tex]

[tex]c^2=\frac{17}{16}[/tex]

[tex]c=\pm \frac{\sqrt{17}}{4}[/tex]

Therefore,

The coordinates of foci=[tex](0,\pm c)=(0,\pm\frac{\sqrt{17}}{4})[/tex]

The coordinated of vertices=[tex](0,\pm a)=(0,\pm 1)[/tex]

Eccentricity, e=c/a

[tex]e=\frac{\frac{\sqrt{17}}{4}}{1}=\frac{\sqrt{17}}{4}[/tex]

First, we have to distribute -10 to 32 and -6, since 32 - 6 is in parentheses.

So, the expression becomes -320 + 60, because -10 × 32 = -320 and -10 × -6 = 60.

So, -320 + 60 = -260
