7 0

Answer:  7) vertex = ∠H       sides = HG and HI

                8) ∠H, ∠IHG, ∠GHI, ∠4

                9) ∠HVI, ∠HVJ, ∠IJV

<u>NOTES:</u>

1) The vertex is the point where the two segments, rays, or lines connect.

2) When naming an angle, the vertex is ALWAYS written in the middle with the sides on the left and right.

Answer:

Add -4x to both sides--> 6x+9=4x-3 and 2x+9=-3

multiply both sides by -1/4 --> -4(5x+7)=-18 and 5x-7=4.5

multiply both sides by 1/4--> 12x+4=20x+24 and 3x+1=5x+6

multiply both sides by -4--> -5x/4=4 and 5x=-16

add -4 to both sides--> 8-10x=7+5x and 4-10x=3+5x

Assuming you are creating a book with 991 pages with a size of 8.5in x 11in, how many words will the story be?
KiRa [710]

This question is solved using proportions, as the table gives us the number of words per page given the dimensions, and the number of pages, which lets us calculate the number of words.

Doing this, we get that the story will be composed of 792,800 words.

-------------------------------------------

  • According to the table, pages of dimensions 8.5in x 11in have 800 words.
  • The book has 991 pages, of 8.5in x 11in dimensions.

Thus, considering that there will be 991 pages, each with 800 words, the total number of words in the story will be of:

991 \times 800 = 792,800

The story will be composed of 792,800 words.

a farmer wants to fence in three sides of a rectangular field shown below with 960 feet of fencing. The other side of the rectan
Alika [10]

9514 1404 393

Answer:

  240 ft by 480 ft

Step-by-step explanation:

Area is maximized when the long side is half the total length of the fence. That makes the short side (out from the river) be half the length of the long side.

The fenced field dimensions are 240 feet by 480 feet.

__

You can let x represent the length of the long side. Then the length of the short side is half the remaining fence: (960 -x)/2.

The total area is the product of these dimensions:

  A = x(960 -x)/2

We note that this is the equation of a parabola with zeros at x=0 and x=960. The maximum will be found on the line of symmetry, halfway between the zeros. That is at x = (0 +960)/2 = 480.

The area is maximized for a long-side dimension of 480 feet. The short sides are 240 feet.

A. Translate each of the following into algebraic expressions: (1 point each)
myrzilka [38]
A. Translate each of the following into algebraic expressions: (1 point each) 1.x plus y squared ---> x + y^2
2.8 times a number, x, decreased by y  ---> 8x - y
3.the sum of x and y, squared ---> (x + y)^2
4.3 times the difference of x and y ---> 3( x - y)
5.6 less than x cubed --- > x^3 - 6


B. Translate the following phrases into algebraic expressions. Explain, in complete sentences, the difference between the two. (3 points)

´twice the sum of x and y ---> 2(x + y)
´the sum of twice x and y ---> 2x + y

The first one adds first x and y, and then doubles the result, while the second one first doubles de value of x and the adds y.


C. Create your own example of a mathematical phrase you might hear in the real world and provide the translation for it. Be sure to identify what part of the phrase i

The sales of this year exceeded the sales of last year in tweny millions.

y = x + 20,000,000, where x represents the sales of last year and y represents the sales of this year,
