Which of the following is a step in simplifying the expression​

Answer:

M = 4pi²a³ / GT²

Step-by-step explanation:

Cross multiply: T² × GM = GMT²

1 × 4pi²a³ = 4pi²a³

It becomes: GMT² = 4pi²a³

Divide both sides by GT² to solve for M

We have : M = 4pi²a³ / GT²

Answer:

angles BED and DEA, and angles AEC and BEC are supplementary angles

Step-by-step explanation:

If you do not know what supplementary angles are, then just know that it means two angles added together that equal 180 degrees. So, all you need to do is find two angles on the picture that equal 180 degrees when added together.

Answer:

y=8⇒8=24x

x=24/8=3

Step-by-step explanation:

The value of y when x = 80 is 20.

It is required to find the value of y.

Arithmetic is the branch of mathematics that deals with the study of numbers using various operations on them. Basic operations of math are addition, subtraction, multiplication and division. These operations are denoted by the given symbols.

Solution:

"Y is directly proportional to X" can be rewritten as a mathematical expression of the form Y = KX

"K" is the constant of proportionality and must be determined from the initial information.

According to given question we have,

If Y = 45 when X=180

It means

45 = 180K

K = 45/180

K = 0.25

Now that we know the value of K, we can use it to calculate the value of Y when X=80

Y = (0.25)(80)

Y=20

Therefore, the value of y when x = 80 is 20.

Answer:

y = -0.5x -2

Step-by-step explanation:

if two lines are perpendicular, their product equals -1

_________________________________________

let the equation of required line be

y = mx + b as given in the problem to be slope intercept form

m = slope

given line

y = 2x

it is also in y = mx + b , comparing this with y =2x

m = 2 and b =0

now

as product of two perpendicular lines = -1

m*2 = -1

thus

m = -1/2 = -0.5

thus,

slope of required line is -0.5

in y = mx + b

m = -0.5

thus,

y = -0.5x + b

given that this line passes through(4,-4)

putting y = -4 and x = 4 in this equation we can find value of b

-4 = -0.5*4 + b

-4 = -2 + b

=> -4 + 2 = b

thus, b = -2

Thus, slope intercept form of equation is y = -0.5x -2

Answer:

[tex]-\frac{26}{2}/ -\sqrt{9}/ 13.5(percent)/ 0/ 13.5[/tex]

Step-by-step explanation:

Answer:

The given linear equation are

⇒9x+3y+12=0....eq1

⇒a1 =9,b1 =3,c1 =12

⇒18x+6y+24...eq2

⇒a2 =18,b2 =6,c2 =24

⇒a1/a2 =9/18  =1/2

​⇒  b1/b2=  3/6 =  1/2

⇒  c1/c2=  12/24=  1/2

comparing

⇒  a1/a2,b1/b2,c1/c2  

⇒  a1/a2=b1/b2=c1/c2

Hence, the line represented by eq1 and eq2 are coincidents

Answer:

[tex]y=100x[/tex]

Step-by-step explanation:

Given that [tex]x[/tex] is the length measured in meters and

[tex]y[/tex] represents the same length measured in centimeters.

Let us first have a look at the relationship between meters and centimeters units of length.

1 unit of length in meters = 100 units of length in centimeters

Therefore, it can be said that:

2 units of length in meters = 200 units of length in centimeters

3 units of length in meters = 300 units of length in centimeters

4 units of length in meters = 400 units of length in centimeters

OR

[tex]x[/tex] units of length in meters = 100[tex]x[/tex] units of length in centimeters

It is given that [tex]y[/tex] is the length in centimeters.

Therefore, the proportional equation can be written as:

[tex]y=100x[/tex]

Answer:

answer is b. a rectangle is folded by a vertical and horizontal line going through its center

Step-by-step explanation:

if you folded it along the lines of symmetry, the rectangle would line up with itself

A rectangle is folded by a vertical and horizontal line going through its center, has all the correct lines of reflectional symmetry for the rectangle.

A well-balanced proportion in which two images or figures are the same size and shape is referred to as symmetry.

When the same figure is obtained following a transformation in geometry whether it be a reflection or a rotation symmetry has occurred.

An example of a shape with reflection symmetry is a rectangle. A line of reflection that passes through the center of two different sides will always be symmetrical.

There are two symmetry lines in a rectangle.

Each side of the rectangle would match up exactly if the rectangle were folded along each line of symmetry.

Keep in mind that a shape must possess at least one line of symmetry in order to qualify as having reflection symmetry.

the answer is 6

Answer:

Interest: Amount Gained: $198,000

Final Balance: Amount After 30 days of Interest: $318,000

Step-by-step explanation:

Equation Used to Solve:

120,000 · 0.055 = 120,000 + (xy)

Let x represent 5.5% of 120,000

Let y represent the number of days.

Solving the equation:

120,000 · 0.055 = 6,600

x = 6,600; y = 30

120,000 + (6,600 · 30) = 120,000 + 198,000

120,000 + 198,000 = 318,000

Answer:

C.  The x-terms are the same, and the constant terms are the same.

Step-by-step explanation:

Solve for x:

7 (x - 4) = 8 (x + 8)

Hint: | Write the linear polynomial on the left-hand side in standard form.

Expand out terms of the left hand side:

7 x - 28 = 8 (x + 8)

Hint: | Write the linear polynomial on the left-hand side in standard form.

Expand out terms of the right hand side:

7 x - 28 = 8 x + 64

Hint: | Move terms with x to the left-hand side.

Subtract 8 x from both sides:

(7 x - 8 x) - 28 = (8 x - 8 x) + 64

Hint: | Combine like terms in 7 x - 8 x.

7 x - 8 x = -x:

-x - 28 = (8 x - 8 x) + 64

Hint: | Look for the difference of two identical terms.

8 x - 8 x = 0:

-x - 28 = 64

Hint: | Isolate terms with x to the left-hand side.

Add 28 to both sides:

(28 - 28) - x = 28 + 64

Hint: | Look for the difference of two identical terms.

28 - 28 = 0:

-x = 64 + 28

Hint: | Evaluate 64 + 28.

64 + 28 = 92:

-x = 92

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of -x = 92 by -1:

(-x)/(-1) = -92

Hint: | Any nonzero number divided by itself is one.

(-1)/(-1) = 1:

Answer: x = -92
