18 4/7 into an improper fraction

Answers

Answer 1

Answer: To find an improper fraction, you want to do 18* 7 which equals, 126, so then 126+4=130. So then 130/7 would be your answer.

Answer 2

Answer:

Final answer:

The mixed number 18 4/7 can be converted to an improper fraction by first multiplying the whole number (18) by the denominator of the fraction (7), then adding the numerator of the fraction (4). This results in the improper fraction 130/7.

Explanation:

The problem is asking to convert the mixed number 18 4/7 into an improper fraction. A mixed number contains a whole number and a proper fraction combined. An improper fraction is a fraction where the numerator (top number) is greater than or equal to the denominator (bottom number).

To convert a mixed number to an improper fraction, you multiply the whole number by the denominator of the fraction, then add the numerator of the fraction.

So in the case of the mixed number 18 4/7, the calculation would be as follows: (18 * 7) + 4 = 130.

So, 18 4/7 as an improper fraction is 130/7.

The question that I'm having issues with is, "The complement of an angle, A, in degrees, is equal to one-sixth of the supplement of the angle, also in degrees. Then A= "I know the answer is 72 degrees, but I don't know how to figure the problem out!

Answers

'Complement' = difference between an angle an 90 degrees.

'Supplement' = difference between an angle and 180 degrees.

Complement of A = 90 - A

Supplement of A = 180 - A

The problem says that the complement is 1/6 of the supplement, right ?

So 90 - A = (1/6) x (180 - A)

Multiply each side of this equation by 6 :

540 - 6 A = 180 - A

Subtract 180 from each side:

360 - 6 A = - A

Add 6A to each side :

360 = 5 A

Divide each side by 5 :

A = 72°

$90-A=(180-A)/(6)\n 540-6A=180-A\n 5A=360\n A=72$

Write an algebraic rule to describe the translation C(5, –4) C’(–2, 1)

Answers

Answer:

The required algebraic rule of translation is $(x,y)\rightarrow (x-7,y+5)$ .

Step-by-step explanation:

The coordinates of a point are C(5, –4) and the coordinates of image are C’(–2, 1).

$C(5,-4)\rightarrow C'(-2,1)$ .... (1)

Let the algebraic rule of translation is

$(x,y)\rightarrow (x+a,y+b)$ .... (2)

From (1) and (2) we get

$x=5,y=-4$

$x+a=-2$

$5+a=-2$

$a=-2-5$

$a=-7$

The value of a is -7.

$y+b=1$

$-4+b=1$

$b=1+4$

$b=5$

The value of b is 5.

The algebraic rule of translation is

$(x,y)\rightarrow (x-7,y+5)$

Therefore the required algebraic rule of translation is $(x,y)\rightarrow (x-7,y+5)$ .

We can solve this by using the formula:
(x, y) (x + a, y + b) = (5,-4) (-2,1)

So, plugging in the values and solving for a and b,
5 + a = -2
a = -8

-4 + b = 1
b = 5

Therefore, the translation is
(x,y) (x - 8, y +5)

You have to simplify this without any negative exponents. Where would I start?

Answers

You have these: (a^m)^n = a^(m*n) and a^(-n) = 1/ (a^n), with n > 0 => (81^5 * y)/(x^5);

Sam rotated parallelogram ABCD 90° clockwise around the origin. If angle A is 130° and angle B is 50°, what is the degree measurement of angle A'?

Answers

Answer-

The measurement of angle A' will be 130° .

Solution-

Transformations like - rotations, reflections, and translations are isometric. That means that these transformations do not change the size of the figure. If the size and shape of the figure is not changed, then the figures are congruent.

It doesn't matter the order or how much degree of rotation has taken place, the final image will be congruent to the original image.

So, even after the rotation of 90° clockwise around the origin, the measurement of angle A will be 130° and so do all the rest of the angles.

Answer:

B, 130 degrees.
